What is the Typical Duration of a Mental Health Rehab Program?

Stress can push the brain to its limits, sometimes distorting perception and creating sensory experiences that feel real but aren’t. While commonly associated with psychotic disorders, hallucinations can also emerge from extreme fatigue, chronic anxiety, or prolonged emotional distress. When stress overwhelms the nervous system, it disrupts normal sensory processing, leading to misinterpretations of reality.

Stress-induced hallucinations can be disorienting, temporarily affecting one’s ability to distinguish between reality and perception. Factors like sleep deprivation, heightened anxiety, and overstimulation can all contribute to these experiences. However, distinguishing between momentary stress-induced distortions and more serious medical concerns is crucial.

This article explores the link between stress and hallucinations, their causes, and when professional intervention is necessary. For those experiencing persistent or distressing hallucinations, seeking professional psychiatric evaluation at Amae Health can provide clarity and evidence-based treatment options.

What Causes Hallucinations?

Hallucinations occur when the brain perceives something that isn’t actually there — whether it’s sights, sounds, smells, or physical sensations. While often linked to psychotic disorders, they can also result from stress, sleep deprivation, and anxiety, which alter brain chemistry and disrupt sensory processing.

‍

Research suggests that stress-induced hallucinations may stem from dopamine and serotonin imbalances. Chronic stress can overactivate the limbic system, increasing dopamine levels, which is linked to hallucinations in psychotic disorders. The perceptual release theory also explains that when sensory input is reduced — due to exhaustion or stress — the brain “fills in the gaps” with internally generated images or sounds.

‍

Neuroimaging studies indicate that abnormal activation in the temporal and frontal lobes is associated with stress-related hallucinations. Understanding these mechanisms helps differentiate temporary hallucinations from more serious conditions.

Common Psychological and Medical Causes

Psychotic Disorders

Psychotic disorders, such as schizophrenia and schizoaffective disorder, are among the most well-known causes of hallucinations. These conditions affect the way the brain processes reality, leading to persistent auditory, visual, or tactile hallucinations. Individuals with psychotic disorders often experience delusions alongside hallucinations, making it difficult to differentiate between what is real and what is not.

Anxiety and Panic Disorders

Although less commonly associated with hallucinations, severe anxiety and panic disorders can lead to sensory distortions. During intense episodes, individuals may experience fleeting visual distortions, auditory misperceptions, or even a sense of detachment from reality. Hypervigilance and overstimulation from chronic anxiety can create a state where the brain misinterprets normal stimuli as hallucinations.

Sleep Deprivation and Fatigue

Lack of sleep can have profound effects on brain function, sometimes leading to hallucinations. Individuals suffering from extreme fatigue, insomnia, or conditions like sleep apnea may experience visual or auditory hallucinations, particularly in the form of fleeting images or phantom sounds. Sleep deprivation alters neurotransmitter levels, making it easier for the brain to misinterpret sensory input.

Substance Use or Withdrawal

Psychoactive substances, including alcohol, stimulants, and hallucinogenic drugs, can cause hallucinations both during use and withdrawal. Substances like LSD or psilocybin directly alter perception, while withdrawal from alcohol or benzodiazepines can lead to temporary hallucinations as the nervous system readjusts. Chronic substance abuse may also cause long-term changes in perception.

Chronic Stress (Hyperstimulation)

Prolonged exposure to stress can lead to a state of hyperstimulation, where the nervous system remains in overdrive. This heightened state of alertness can distort sensory processing, making individuals more susceptible to hallucinations. Chronic stress alters cortisol levels, impacting brain areas responsible for perception and memory, potentially leading to transient hallucinatory experiences.

How Can Stress Cause Hallucinations?

Dissociation as a Response to Stress

Dissociation is a defense mechanism triggered by overwhelming stress, leading to a sense of detachment from reality. A study published in Schizophrenia Bulletin Open found that individuals with a history of trauma are significantly more likely to experience hallucinations following acute stressors, reinforcing the link between stress, dissociation, and sensory distortions.

Individuals experiencing dissociation may feel disconnected from their surroundings, themselves, or time. In severe cases, dissociation can manifest as hallucinations, where the brain creates sensory experiences to cope with the overwhelming stress and emotional dysregulation.

Acute Stress and Hallucinations

Acute stress triggers the body's fight-or-flight response, flooding the system with stress hormones like cortisol and adrenaline. This heightened state of alertness can lead to sensory distortions, causing brief auditory or visual hallucinations. Individuals under extreme stress may misinterpret sounds, see fleeting images, or feel an unexplained presence due to heightened neural activity and hyper-awareness.

Chronic Stress (Hyperstimulation) and Its Impact

Chronic stress results in long-term hyperstimulation of the nervous system, altering brain chemistry and perception. Persistent stress can disrupt neurotransmitter balance, increasing susceptibility to hallucinations. Over time, heightened stress levels can cause hallucinations like auditory whispers, visual flashes, or phantom sensations as the brain struggles to filter sensory input properly.

Sleep Deprivation and Hallucinations

Stress often leads to sleep deprivation, which in turn increases the risk of hallucinations. Sleep deprivation disrupts cognitive processing, causing the brain to enter micro-dream states while awake. This can result in visual distortions, auditory misinterpretations, or a sensation of movement. The longer an individual goes without sleep, the more severe these hallucinations can become.

Types of Stress-Related Hallucinations

Auditory Hallucinations

Auditory hallucinations are among the most common stress-induced hallucinations. Individuals may hear whispers, distant voices, or even music when no external sound is present. These hallucinations can be disorienting, often occurring during periods of extreme anxiety or fatigue or after prolonged exposure to stress. According to research from Yale’s COPE Project, recent social stress directly correlates with both the frequency and distress levels of auditory hallucinations, highlighting the role of everyday stressors in exacerbating these experiences. Managing stress levels and improving sleep quality can help reduce these occurrences.

Visual Hallucinations

Visual hallucinations involve seeing objects, shapes, or figures that are not actually there. They can appear as fleeting shadows, flashes of light, or fully formed images. Stress-induced visual hallucinations often stem from sleep deprivation or severe emotional distress. Practicing relaxation techniques, mindfulness, and ensuring adequate rest can help minimize these experiences.

Tactile and Somatic Hallucinations

Tactile hallucinations create the sensation of physical touch when there is no actual contact. Individuals might feel crawling, tingling, or pressure on their skin. These can occur due to heightened anxiety, sleep deprivation, or intense stress. Grounding exercises and cognitive behavioral therapy (CBT) can be beneficial in managing these symptoms.

Olfactory and Gustatory Hallucinations

Olfactory hallucinations involve detecting smells that are not present, while gustatory hallucinations cause individuals to perceive unusual tastes. These can be triggered by prolonged stress, migraines, or neurological conditions. Identifying and managing stressors, along with medical evaluation, can help determine the cause and reduce their occurrence.

When Should You Be Concerned About Stress-Induced Hallucinations?

Signs You Should Seek Help

If hallucinations become frequent, intense, or start interfering with daily life, seeking professional help is essential. Persistent hallucinations, confusion, or distress warrant medical evaluation. Identifying underlying causes, such as extreme stress, sleep disorders, or mental health conditions, can help in developing an effective treatment plan to restore well-being.

How Are Stress-Related Hallucinations Treated?

Short-Term Coping Strategies

Immediate coping mechanisms include deep breathing, grounding techniques, and mindfulness exercises. Engaging in relaxation activities like meditation or progressive muscle relaxation can help reduce the intensity of hallucinations. Addressing stressors and improving sleep hygiene can also provide quick relief.

Long-Term Treatment Options

Managing stress-induced hallucinations requires a combination of professional and self-care approaches. Amae Health’s specialists offer evidence-based therapies, including cognitive behavioral therapy (CBT) and medication management, to help patients regain stability.

Therapy, such as cognitive behavioral therapy (CBT), can help address underlying stressors. In some cases, medication may be recommended. For individuals with chronic stress-induced hallucinations, psychiatric interventions such as medication targeting neurotransmitter regulation may provide significant relief. Lifestyle changes, including regular exercise, balanced nutrition, and structured routines, can further support mental and emotional well-being.

Regaining Control Over Stress-Induced Hallucinations

Stress-induced hallucinations can be disturbing, but they are often temporary and manageable with the right strategies. While occasional hallucinations caused by stress, sleep deprivation, or anxiety might not indicate a deeper issue, persistent or distressing experiences should not be ignored. 

Seeking professional help, practicing stress management techniques, and maintaining a healthy lifestyle can significantly reduce the risk of experiencing hallucinations. If you or someone you know is struggling with stress-related hallucinations, remember that support is available, and addressing the root cause can lead to long-term relief.

FAQ

Can anxiety cause hallucinations? 

Yes, severe anxiety and chronic stress can contribute to hallucinations, particularly auditory or visual ones. Anxiety-induced hallucinations often occur during heightened distress or panic attacks.

Are stress hallucinations dangerous? 

While stress-induced hallucinations can be distressing, they are not inherently dangerous. However, they may indicate underlying mental health concerns that require attention.

Do hallucinations from stress go away on their own? 

In many cases, stress-related hallucinations subside once the underlying stressor is managed. Prioritizing stress reduction, proper sleep, and relaxation techniques can help accelerate recovery. If hallucinations persist, seeking medical guidance is recommended.

TMS is not shock therapy. That is the first thing to settle in any TMS vs ECT comparison, because that phrase, and all the baggage that comes with it, refers to electroconvulsive therapy (ECT), not transcranial magnetic stimulation. TMS uses magnetic pulses, involves no anesthesia and no seizure, and you drive yourself home afterward. Both are evidence-based brain stimulation treatments for depression, and both work. They differ substantially in how they work, what the treatment is like to go through, and who they are typically used for. Knowing the difference between TMS and ECT is what lets you and your psychiatrist match the treatment to the situation.

What Is TMS?

Transcranial magnetic stimulation delivers focused magnetic pulses through a coil resting on the scalp to a specific region of the brain, usually the left dorsolateral prefrontal cortex, which is involved in mood regulation. The stimulation is targeted to that one site rather than generalized across the brain, and because it stimulates a small area without inducing a seizure, the procedure needs no anesthesia and takes place in an ordinary clinic or office, as the National Institute of Mental Health describes. FDA clearance came in 2008 for major depressive disorder, with obsessive-compulsive disorder added in 2018.

‍

At our clinics, a standard course of TMS therapy is 20 to 30 sessions, one per weekday, 30 to 40 minutes each, over about four to six weeks, and you sit awake in a chair for every one of them. No seizure is induced, nothing enters your bloodstream, and when the session ends you can drive yourself home and return to your day.

What Is ECT?

Electroconvulsive therapy is a controlled medical procedure performed under general anesthesia. You are given a short-acting anesthetic and an intravenous muscle relaxant to prevent movement, and electrodes on the scalp deliver a brief electrical current that produces seizure activity in the brain lasting under a minute. You wake within minutes, recover over the following hour or so, and need someone to take you home. A typical course is three sessions a week until symptoms improve, usually within 6 to 12 treatments.

‍

ECT is one of the oldest treatments in psychiatry and one of the most effective for severe depression. The FDA's clearance covers catatonia and severe depressive episodes in people age 13 and older with major depression or bipolar disorder who have not responded to other treatments or need a rapid response, and it is also used for mania and for certain presentations of schizophrenia and schizoaffective disorder. It is most often reserved for situations where fast, powerful relief matters: acute suicidality, depression with psychotic features, or catatonia.

‍

The stigma around ECT comes from portrayals that are decades out of date, from an era before anesthesia and muscle relaxants were used. Modern ECT is delivered in a monitored setting by a full medical team, and its main drawback is not what those old images suggest. It is the effect on memory, covered below.

TMS vs ECT: Side-by-Side Comparison

Effectiveness: What the Research Shows

Both treatments work. In head-to-head trials of electroconvulsive therapy vs TMS, ECT comes out ahead. A 2014 systematic review and meta-analysis in Depression Research and Treatment pooled nine randomized clinical trials comparing the two, with 384 participants in total. Both groups improved significantly. On the Hamilton Depression Rating Scale, the standard clinician-rated measure, scores fell by an average of 15.4 points with ECT and 9.3 points with TMS, a statistically significant difference (P = 0.011). The author concluded that ECT produced larger reductions in depressive symptoms, while the results also supported the therapeutic validity of TMS for people with treatment-resistant depression.

‍

A few things keep that finding in proportion. The trials were conducted between 2000 and 2011, largely with early TMS protocols. And "more effective" is not the same as "the right choice." Real-world TMS outcomes come from a different population. In naturalistic data from 42 U.S. clinics, 58% of outpatients with medication-resistant depression responded to a standard course and 37% reached remission. For someone whose depression has resisted medication but who is stable enough for outpatient care, that is the relevant number.

‍

In the head-to-head studies that exist, ECT delivers stronger short-term symptom reduction. TMS delivers a meaningful effect without anesthesia, without a hospital, and without the recovery and memory considerations described next.

Side Effects and Memory Concerns

Memory is the question people bring to this comparison more than any other, and it deserves a direct answer.

‍

ECT is associated with memory effects, particularly for events around the time of treatment. NIMH describes memory loss close to the treatment period that is sometimes more severe but usually improves over the days and weeks after the course ends, alongside headaches, upset stomach, muscle aches, and short-lived confusion. The largest analysis of the question, a 2010 meta-analysis in Biological Psychiatry covering 84 studies and 2,981 patients, found that measurable cognitive effects were mainly limited to the first three days after treatment. By 4 to 15 days, nearly all measures had recovered, and after 15 days processing speed, working memory, new learning, and some aspects of executive function had improved beyond where they were before treatment, most likely because the depression itself had lifted. Some people do report longer-lasting gaps in personal memories from the months around treatment, and that possibility belongs in the conversation before ECT.

‍

TMS carries no known negative effect on memory or thinking, and it requires no anesthesia. Its side effects are local: discomfort where the coil sits, tingling or twitching of scalp or facial muscles during the pulses, mild headache, and occasional brief lightheadedness. Those usually fade within the first week. Seizure is the one serious risk, and it is exceedingly rare. Screening for seizure history, metal in the head, and implanted devices is what keeps it that way.

What to Expect: The Treatment Experience

The daily reality of the two treatments could not be more different.

‍

A TMS session is a 30-to-40-minute appointment. You sit in a chair, awake, while the coil delivers pulses that feel like tapping on the scalp. When it ends, you stand up, get in your car, and go on with your day, then repeat tomorrow. There is no downtime and no preparation beyond an initial screening visit.

‍

An ECT session is a medical procedure. You fast beforehand, an IV is placed, and you are under anesthesia for a few minutes while the treatment is delivered in a hospital or specialized clinic with an anesthesia provider and a psychiatrist present. You wake up groggy, spend time in recovery, and need someone to take you home. Over several sessions a week for several weeks, that is a real commitment from you and whoever supports you, and ECT is sometimes delivered during an inpatient stay rather than as an outpatient.

Who Is Each Treatment Typically Recommended For?

These are different tools for different clinical pictures, not simply a better and a worse option.

‍

ECT is typically recommended when depression is severe, acute, or urgent, and the speed of response matters: someone at high risk of suicide, someone with psychotic depression, someone with catatonia, or someone who has not responded to multiple treatments. The trade-off of anesthesia and memory effects is accepted because the alternative is worse, and for anyone in that situation care for suicidal thoughts comes first.

‍

TMS is typically recommended for moderate or treatment-resistant depression in someone who is stable enough for outpatient care and can attend daily sessions, when there is no need for the fastest possible response. It is often the next step after antidepressants have failed and before ECT would be considered. For that person, a treatment without anesthesia, without memory effects, and without disruption to work or family life has real value, even if its average effect size is smaller.

Talking to a Psychiatrist About Your Options

Choosing between TMS and ECT is a clinical decision, made with a psychiatrist, that turns on three things: how severe your depression is, how urgently it needs to change, and what you have already tried. It is not a decision to make from a comparison table alone, including this one.

‍

At Amae, we offer TMS at our Los Angeles, Los Altos, and San Mateo clinics as part of our integrated outpatient clinics, where psychiatry, therapy, primary care, and peer support come from one team. We do not offer ECT. If our psychiatrists conclude that ECT is the better clinical fit for you, they will say so and help coordinate a referral, because the goal is the right treatment, not the treatment we happen to provide. If you are trying to work out where you stand, talk with an Amae psychiatrist. And if you are having thoughts of suicide right now, call or text 988, the Suicide and Crisis Lifeline.

Frequently Asked Questions

Is TMS the same as ECT?

No, and it is not "shock therapy" either. That phrase refers to ECT. TMS uses magnetic pulses targeted to one region of the brain, with no anesthesia and no seizure, and you stay awake and drive yourself home. ECT uses electrical stimulation to produce a brief, controlled seizure under general anesthesia in a monitored medical setting.

Does TMS cause memory loss like ECT can?

No. TMS has no known negative effect on memory or thinking; its side effects are scalp discomfort and headache, both short-lived and usually gone within a week. ECT can cause memory loss around the time of treatment that typically improves over the weeks after the course ends.

Which is more effective, TMS or ECT?

In head-to-head research, ECT produces larger short-term symptom reductions. A 2014 meta-analysis of nine randomized trials found average Hamilton scale drops of 15.4 points with ECT versus 9.3 with TMS, with both treatments producing significant improvement. TMS remains a well-supported outpatient option without anesthesia or recovery time, so "more effective" is not the same as "right for your situation."

Is ECT still used today?

Yes. ECT remains a well-established, evidence-based treatment, typically used for severe, urgent, psychotic, or catatonic depression and for depression that has not responded to other treatments. The stigma around it comes from decades-old portrayals that do not resemble modern practice.

Can you drive yourself home after TMS or ECT?

After TMS, yes. There is no anesthesia or sedation, so people typically drive themselves home and return to their day immediately. After ECT, no. General anesthesia means you need a support person to take you home and some recovery time before normal activities.

Does Amae Health offer ECT?

No. We offer TMS at our Los Angeles, Los Altos, and San Mateo clinics as part of integrated psychiatric care. We do not offer ECT, and if a psychiatrist concludes that ECT is the better fit for your situation, we help coordinate a referral to a provider who does.

‍

f you are comparing TMS, ketamine, and Spravato for depression, you have probably reached the point where standard antidepressants have not done enough. All three are evidence-based options for treatment-resistant depression, and beyond that they have little in common. TMS is a course of magnetic stimulation delivered while you sit awake in a chair. Ketamine is an anesthetic given by IV, used off-label for depression. Spravato is a nasal spray made from esketamine, one of the two mirror-image forms that make up ketamine, with its own FDA approval and its own rulebook.

‍

None of the three is universally better. They differ in mechanism, speed, setting, and monitoring, and the right one depends on your clinical history and how you respond. Treatment-resistant depression generally means depression that has not adequately improved after at least two antidepressants taken at a proper dose for long enough, and that is the group where all three are most often used.

What Is TMS?

Transcranial magnetic stimulation uses a coil placed against the scalp to deliver focused magnetic pulses to the left dorsolateral prefrontal cortex, a region involved in mood regulation. The FDA first cleared TMS for major depressive disorder in 2008, according to the National Institute of Mental Health. It is delivered in an office, with no anesthesia and no medication.

‍

Our standard TMS course runs 20 to 30 daily sessions over four to six weeks, each 30 to 40 minutes long. You stay awake throughout and drive yourself home afterward. In real-world outcome data from 42 U.S. practices, more than half of patients with medication-resistant depression responded to a standard course, and more than a third reached remission.

What Is Ketamine Therapy?

Ketamine has been an FDA-approved anesthetic since 1970. Its use for depression is off-label: prescribed for a purpose the FDA has not formally approved, which is legal and common in medicine but leaves the safeguards less standardized. It is usually given as an IV infusion in a monitored clinic, as a series of sessions over a few weeks.

‍

Ketamine blocks the NMDA receptor, a glutamate receptor, rather than acting on serotonin like standard antidepressants, and that difference is thought to explain its speed. In a landmark 2006 trial, 18 people with treatment-resistant depression received a single infusion of 0.5 mg/kg, and their symptoms improved significantly within 110 minutes. By the next day, 71% had responded and 29% were in remission. One week later, 35% still met the response threshold. Rapid, real, and often short-lived.

‍

The catch is in the monitoring. Ketamine causes dissociation, a sense of detachment from your body or surroundings, plus sedation and blood pressure rises during and after the infusion, so you are observed until those effects pass and cannot drive that day. In a 2017 consensus statement in JAMA Psychiatry, an American Psychiatric Association task force found the evidence for rapid antidepressant effects convincing but the studies small, the longer-term efficacy data lacking, and the safety data on repeated dosing limited.

What Is Spravato (Esketamine)?

Ketamine is a mixture of two mirror-image molecules. Spravato is esketamine, one of those two, delivered as a nasal spray. Unlike IV ketamine, it has FDA approval for depression. The original approval came in March 2019 for treatment-resistant depression alongside an oral antidepressant, a second indication followed for adults with major depressive disorder and acute suicidal thoughts or behavior, and in January 2025 the FDA approved Spravato as a standalone monotherapy for treatment-resistant depression, with no oral antidepressant required, per the current prescribing information.

‍

That approval comes with a rulebook. Spravato can only be given at a setting certified under a Risk Evaluation and Mitigation Strategy (REMS) program: you take the spray under supervision, you are monitored for at least two hours before an assessment clears you to leave, and you cannot drive until the next day after a restful sleep. Its label carries a boxed warning for sedation, dissociation, respiratory depression, abuse and misuse, and suicidal thoughts and behaviors in younger patients.

‍

So is Spravato the same as ketamine? Related, not identical: same molecular family, same receptor, similar rapid onset and dissociative effects, but a different route, a formal FDA indication, and mandatory monitoring rules that off-label ketamine does not carry. For most people comparing TMS vs Spravato, those rules and insurance coverage are the practical differences that matter.

TMS vs Ketamine vs Spravato: Side-by-Side Comparison

Onset and Duration of Effect

Speed is the clearest dividing line. TMS builds gradually, and many people do not notice a clear change until the second or third week or later. Ketamine and Spravato can shift symptoms within hours to days.

‍

Speed and staying power are different things. Ketamine's effect after a single infusion often fades within a week or two, which is why it is given as a series with maintenance dosing. Spravato starts at twice a week and tapers, with the need for continued treatment reassessed along the way. Research on durability is still developing for all three, and none should be described as permanent.

Side Effects and Safety Considerations

TMS side effects are local and short-lived: scalp discomfort where the coil sits, headache, and sometimes brief lightheadedness or facial muscle twitching during the pulses. These usually settle within the first week, and because nothing enters the bloodstream there is no weight gain, sexual dysfunction, or sedation. Seizure is the one serious risk, exceedingly rare, and TMS is not used in people with a seizure history, metal in the head, or implanted electronic devices.

‍

Ketamine and Spravato share a different profile. The most common reactions to Spravato in trials were dissociation, dizziness, nausea, sedation, vertigo, numbness, anxiety, lethargy, increased blood pressure, vomiting, feeling drunk, and headache. Those effects peak in the hours after dosing, which is what the monitoring window is for, and both drugs carry a potential for misuse that shapes who is a candidate. Each option has its own screening, and a contraindication to one does not rule out the others.

Cost and Insurance

For TMS, most commercial insurers cover treatment for major depressive disorder once eligibility criteria are met, typically a confirmed diagnosis and documented antidepressant trials without adequate relief. Prior authorization is standard. For TMS we take all commercial insurance plans, cash pay is available, and authorization is something our intake team manages for you.

‍

Spravato is more commonly covered than off-label ketamine because it has an FDA indication insurers can write criteria around, though prior authorization and documentation of failed antidepressant trials are typically required. Ketamine infusion coverage varies widely, and many clinics are self-pay. Published cost estimates vary so much by dose, frequency, and insurance status that a single dollar figure would mislead; ask each provider and your insurer directly.

Can These Treatments Be Combined?

Sometimes, and the research is early. A 2024 systematic review found six published studies on combining TMS with ketamine, mostly case reports plus one retrospective review and one small pilot, and reported substantial and sustained improvement with generally mild side effects. The authors also said the designs were too varied and the samples too small for firm conclusions, and called for randomized trials.

‍

In practice, TMS and Spravato are sometimes used one after the other. Combining any of these is a clinical judgment a psychiatrist makes from your history, not a general recommendation, and the more common pattern is to use one, assess the response, then decide.

Choosing Between Them: What Influences the Decision

A psychiatrist weighing these options usually works through a short list:

‍

• Treatment history. Which antidepressants, at what doses, for how long, and whether psychotherapy has been tried.
• How urgently relief is needed. When symptoms are severe or suicidal thoughts are present, a faster-acting option may take priority, alongside care for suicidal thoughts.
• Tolerance for the experience. Dissociation and a two-hour monitored window, versus a daily half-hour appointment for several weeks with no drug effects.
• Practical constraints. Whether you can get to daily sessions, whether someone can drive you home after Spravato or ketamine, and what your insurance will authorize.
• Health factors. Seizure history, metal implants, blood pressure, and any history of substance misuse each rule options in or out.
• What else is in place. Any of the three works better inside ongoing psychiatric care and therapy than as a standalone fix.

Making the Decision With an Integrated Care Team

TMS, ketamine, and Spravato are tools, and tools do their best work inside a plan: a psychiatrist who knows your history, a therapist working alongside the biological treatment, and a team that notices when the plan needs to change.

‍

That is how we work. At Amae, our one-team care model combines psychiatry, therapy, primary care, and peer support, and TMS and Spravato are available through our Los Angeles and Bay Area clinics as part of that care. If you have been through the antidepressant cycle and want a clear, unhurried look at what comes next, talk with an Amae psychiatrist about your options. If you are in crisis or thinking about suicide, call or text 988 now.

Frequently Asked Questions

What is the difference between TMS and ketamine for depression?

TMS stimulates the brain with magnetic pulses over a course of daily outpatient sessions, with no drug, no sedation, and no monitoring afterward. Ketamine is a medication that acts on NMDA receptors, given by infusion or, as esketamine, by nasal spray, with monitored sedation and dissociation and often faster but shorter-lived effects.

Is Spravato the same as ketamine?

Related but not identical. Spravato is esketamine, the S-enantiomer of the ketamine molecule, delivered as an FDA-approved nasal spray under a required monitoring program. Ketamine infusions use the full ketamine compound and are prescribed off-label for depression, without an FDA indication for that use.

Is Spravato only approved with an antidepressant?

Not anymore. The original 2019 approval was for use alongside an oral antidepressant, and in January 2025 the FDA also approved Spravato as a standalone monotherapy for adults with treatment-resistant depression. Whether it is used alone or with an antidepressant is a decision your psychiatrist makes based on your situation.

Which works faster, TMS or Spravato?

Spravato. Esketamine and ketamine can produce symptom change within hours to days, while TMS builds gradually across a four-to-six-week course. Faster onset does not mean more durable improvement, and both durability and side effects belong in the comparison.

Can TMS and Spravato be used together?

Sometimes, as a clinical decision made with a psychiatrist based on your individual history. Both can be part of a broader treatment-resistant depression plan alongside medication and therapy, and the evidence on combining them is still early.

Is ketamine or Spravato covered by insurance?

Spravato is more commonly covered, because it has an FDA indication insurers can build criteria around, though prior authorization and proof of failed antidepressant trials are usually required. Coverage for off-label ketamine infusions varies widely and is often self-pay. Confirm with the provider and your insurer before starting.
