Autoimmune sleep disorders occur when the immune system turns on the brain’s own sleep-regulating machinery, destroying neurons and disrupting the circuits that control wakefulness, dreaming, and consciousness itself. The damage can be catastrophic, up to 95% of critical wake-promoting neurons gone, yet patients often spend a decade being told they’re depressed or lazy before anyone orders the right test. Understanding what’s actually happening changes everything about how these conditions are diagnosed and treated.
Key Takeaways
- In narcolepsy type 1, the immune system destroys hypocretin-producing neurons in the hypothalamus, eliminating the brain’s primary wake-promoting signal
- Specific HLA genetic variants significantly raise the risk of autoimmune sleep disorders, though genes alone don’t determine who develops them
- Viral infections, including the 2009 H1N1 pandemic, have been linked to triggering autoimmune sleep disorders in genetically susceptible people
- Autoimmune encephalitis can produce a wide range of sleep disturbances, insomnia, hypersomnia, disrupted sleep-wake cycles, depending on which brain region the antibodies target
- Treatment typically combines immunotherapy to address the underlying attack with symptom management and lifestyle changes
What Are Autoimmune Sleep Disorders?
Sleep isn’t just rest. It’s an active, precisely orchestrated neurological process controlled by specific brain circuits, and like any biological system, those circuits can become targets for a misdirected immune response.
Autoimmune sleep disorders are conditions in which the immune system attacks components of the brain’s sleep-wake regulatory system. The targets vary: in some conditions, it’s the neurons that produce wake-promoting chemicals; in others, it’s specific cell-surface receptors or synaptic proteins. What they share is a common logic, the immune system mistakes “self” for “enemy” and fires accordingly.
These disorders sit at a strange intersection of neurology and immunology, which partly explains why they’re so frequently missed.
When someone can’t sleep, the first instinct is rarely to check their antibody levels. Disrupted sleep patterns have many causes, and the autoimmune ones tend to hide behind more familiar explanations, depression, laziness, poor sleep habits, for years.
Estimates suggest that up to 20% of people with autoimmune diseases experience significant sleep-related problems, though the true figure is likely higher given how often these conditions go unrecognized. The downstream consequences reach well beyond tired mornings: cognitive impairment, mood disruption, metabolic dysregulation, and reduced quality of life compound over time.
What Autoimmune Diseases Cause Sleep Problems?
Some autoimmune conditions attack the sleep system directly.
Others disrupt sleep indirectly through inflammation, pain, or the effects of treatment.
Lupus, for instance, is associated with sleep disturbances through several overlapping mechanisms, how lupus affects sleep involves inflammatory cytokines crossing into the central nervous system, pain flares interrupting sleep architecture, and fatigue that paradoxically coexists with poor-quality rest. Rheumatoid arthritis and multiple sclerosis follow similar patterns.
Hashimoto’s thyroiditis, an autoimmune thyroid condition, is increasingly linked to Hashimoto’s disease and sleep apnea, where thyroid dysfunction alters upper airway muscle tone and respiration during sleep.
Even the medications used to treat autoimmune conditions can be culprits, corticosteroids, for example, have well-documented effects on how corticosteroids affect sleep quality, often suppressing slow-wave sleep and increasing nighttime arousal.
Then there are the conditions where the sleep system itself is the primary target, narcolepsy, autoimmune encephalitis, and related disorders, where the immune attack is not collateral damage but the central event.
Is Narcolepsy an Autoimmune Disorder?
The evidence is now strong enough that most sleep medicine specialists treat narcolepsy type 1 as an autoimmune disease, even though the precise autoantibody responsible hasn’t been definitively confirmed in all cases.
Here’s what we know. Narcolepsy type 1 is defined by the near-total loss of hypocretin (also called orexin), a neuropeptide produced by a small cluster of neurons in the hypothalamus that acts as the brain’s primary “stay awake” signal. Post-mortem brain tissue from people with narcolepsy shows a dramatic reduction in these neurons, with some studies finding losses of 85–95% compared to controls.
That’s not a gradual decline. That’s destruction.
The genetic fingerprint supports an autoimmune mechanism. More than 98% of people with narcolepsy-cataplexy carry the HLA-DQB1*06:02 allele, a gene variant that influences how the immune system recognizes self from non-self. HLA genes are the hallmark of autoimmune susceptibility; their strong association with narcolepsy is one of the clearest genetic signals in all of sleep medicine.
Complex interactions involving HLA-DR and HLA-DQ alleles confer risk across multiple ethnic populations, suggesting the mechanism is not population-specific.
The environmental trigger picture strengthened considerably after 2009. Following the H1N1 influenza pandemic, Finland and several other countries recorded sharp increases in childhood narcolepsy cases. In Finland specifically, the spike followed both natural H1N1 infection and the Pandemrix vaccine used in the pandemic response, pointing to molecular mimicry, where a pathogen or vaccine antigen resembles a self-protein closely enough to provoke an immune response that then turns on the brain.
In narcolepsy type 1, the immune system can destroy up to 95% of the roughly 70,000 neurons responsible for maintaining wakefulness, yet the average time from symptom onset to diagnosis is still around 10 years. The biological devastation is nearly complete before most patients ever hear the word “hypocretin.”
Common Autoimmune Sleep Disorders
Narcolepsy type 1 is the most studied, but it’s not the only condition in this category.
Narcolepsy Type 1 produces a recognizable cluster: overwhelming daytime sleepiness, cataplexy (sudden muscle weakness triggered by emotion, laughing, surprise, anger), sleep paralysis, and hypnagogic hallucinations at sleep onset.
The cataplexy is the telling symptom, it’s essentially REM sleep intrusion into wakefulness, the body briefly losing muscle tone the way it would during dreaming.
Narcolepsy Type 2 shares the sleepiness without confirmed cataplexy. Hypocretin levels may be normal or borderline. Whether it’s a distinct condition or an early or incomplete form of type 1 is still debated.
Idiopathic Hypersomnia involves profound daytime sleepiness despite sleeping 10–12 hours or more.
Sleep is long but unrefreshing, people wake feeling worse than when they went to bed, a pattern known as non-restorative sleep. An autoimmune mechanism is suspected in some cases; there’s evidence of a GABA-A receptor-potentiating substance in the cerebrospinal fluid of some patients, though the field is still working out the details.
Kleine-Levin Syndrome is rare and strange. Affected people, predominantly adolescent males, cycle in and out of episodes lasting days to weeks where they sleep up to 20 hours a day, eat compulsively, experience cognitive confusion, and show altered behavior.
Between episodes, they’re completely normal. The episodic, relapsing-remitting pattern and the presence of HLA associations in some patients suggest immune involvement, though direct autoantibody evidence remains limited.
Autoimmune encephalitis encompasses a growing list of antibody-mediated brain disorders, many of which produce dramatic sleep disturbances as part of their presentation, covered in more detail below.
Comparison of Major Autoimmune Sleep Disorders
Disorder Autoimmune Target / Mechanism Core Sleep Symptoms Key Diagnostic Test First-Line Treatment
Narcolepsy Type 1 Destruction of hypocretin neurons (hypothalamus) Excessive daytime sleepiness, cataplexy, sleep paralysis, hypnagogic hallucinations MSLT + CSF hypocretin level Sodium oxybate, modafinil, antidepressants for cataplexy
Narcolepsy Type 2 Unknown; no confirmed hypocretin loss Excessive daytime sleepiness (no cataplexy) MSLT Modafinil, stimulants
Idiopathic Hypersomnia Suspected GABA-A receptor potentiation Long, unrefreshing sleep; severe sleep inertia MSLT + sleep diary/actigraphy Modafinil, clarithromycin (off-label), flumazenil
Kleine-Levin Syndrome Unknown; HLA associations suspected Recurrent hypersomnia episodes (up to 20 hrs/day), hyperphagia, cognitive changes Clinical criteria + EEG/MRI Lithium (prophylaxis), supportive care
Autoimmune Encephalitis Neuronal surface or synaptic antibodies Insomnia, hypersomnia, or disrupted sleep-wake cycle depending on antibody Antibody panel (serum + CSF) IVIG, plasma exchange, corticosteroids, rituximab
Can Autoimmune Encephalitis Cause Insomnia and Sleep Disturbances?
Yes, and the sleep symptoms can be severe enough to be the presenting complaint before anyone thinks to look for an encephalitis diagnosis.
Autoimmune brain diseases caused by antibodies attacking neuronal proteins produce some of the most dramatic sleep phenotypes in medicine. Anti-NMDA receptor encephalitis, the most common form, can cause complete sleep-wake cycle reversal, patients awake at night, unresponsive during the day, along with psychosis, seizures, and movement abnormalities.
The sleep disruption here isn’t secondary to the brain inflammation; it’s a direct consequence of NMDA receptors being blocked at key regulatory sites.
Anti-IgLON5 disease is a more recently described condition that’s particularly striking from a sleep perspective. Patients develop an unusual parasomnia, abnormal, complex behaviors during sleep that don’t fit neatly into any standard category, alongside breathing problems during sleep, gait disturbances, and cognitive decline. Brain tissue from affected patients shows tau accumulation in sleep-regulating regions of the brainstem, suggesting the autoimmune attack triggers a secondary neurodegeneration.
Morvan’s syndrome, caused by CASPR2 or LGI1 antibodies, produces severe insomnia, sometimes total insomnia, along with neuromyotonia (muscle twitching), hallucinations, and dysautonomia.
The insomnia in Morvan’s can be so profound it resembles fatal familial insomnia, a prion disease. Recognition matters here, because unlike the prion disease, Morvan’s can respond to immunotherapy.
Autoimmune Encephalitis Antibodies and Their Sleep-Related Manifestations
Antibody Target Associated Condition Sleep Disturbance Produced Response to Immunotherapy
NMDA receptor Anti-NMDA receptor encephalitis Sleep-wake cycle reversal, hypersomnia Generally good with early treatment
LGI1 LGI1 antibody encephalitis Insomnia, REM sleep behavior disorder, faciobrachial dystonic seizures Moderate to good
CASPR2 Morvan’s syndrome, CASPR2 encephalitis Severe or total insomnia, abnormal movements in sleep Variable; some cases respond well
IgLON5 Anti-IgLON5 disease Complex parasomnia, sleep-disordered breathing, NREM and REM abnormalities Partial; neurodegeneration limits recovery
GABA-B receptor GABA-B encephalitis Insomnia, status epilepticus Moderate response
AMPA receptor AMPA receptor encephalitis Sleep dysregulation, psychiatric symptoms Variable
Are There Sleep Disorders Caused by Antibodies Attacking the Brain?
This is exactly the right question, and the answer has been reshaping neurology over the past two decades.
The discovery of specific neuronal surface antibodies has transformed conditions once written off as “psychiatric” or “unknown encephalopathy” into diagnosable, treatable autoimmune diseases.
The key insight is that antibodies targeting surface proteins on neurons, receptors, ion channel complex proteins, can alter neuronal function in real time, often reversibly, in contrast to antibodies that target intracellular proteins (which typically cause damage through T-cell mechanisms and are less reversible).
Sleep is particularly vulnerable because the circuits controlling it are concentrated in specific brainstem and hypothalamic structures. When antibodies hit the wrong receptor in the wrong place, the whole system can go haywire: the switch between wakefulness and sleep stops working reliably, REM intrudes into wakefulness, or the person simply cannot maintain sleep at all.
The expanding list of pathogenic antibodies, including those targeting NMDA, LGI1, CASPR2, GABA-B, AMPA, and IgLON5, means that what was once an idiopathic sleep problem may turn out, on the right antibody panel, to be a treatable autoimmune condition.
Testing is still underutilized, partly because the conditions are rare and partly because sleep complaints rarely trigger an autoimmune workup in routine practice.
Causes and Mechanisms: How Does the Immune System Disrupt Sleep?
The relationship between the immune system and sleep runs deeper than most people realize. Sleep itself is immunomodulatory, it’s when the body consolidates immune memory, reduces inflammatory load, and resets cytokine levels. Chronic sleep restriction, even modest reductions to 6 hours a night, measurably elevates inflammatory markers including IL-6 and TNF-alpha.
The immune system and sleep are not separate systems with occasional interactions; they’re deeply co-regulated.
In autoimmune sleep disorders, this relationship breaks down in a specific direction: instead of sleep supporting immune balance, the immune system actively attacks the architecture of sleep. Three broad mechanisms drive this.
Molecular mimicry is the best-supported trigger for narcolepsy. A viral protein, or occasionally a vaccine antigen, resembles a self-peptide closely enough that the immune response generated against the pathogen cross-reacts with brain tissue.
The H1N1 connection is the clearest example: a surface protein on the virus shares structural similarities with a hypocretin receptor peptide, and in genetically susceptible people, the immune response overshoots.
Direct antibody-mediated damage drives the encephalitis syndromes. Here, antibodies bind to neuronal surface proteins, blocking their function, triggering receptor internalization, or activating complement to directly destroy synapses.
Neuroinflammation, diffuse inflammation within the central nervous system, can disrupt sleep-wake regulation without a specific autoantibody target. Elevated cytokines in the brain shift sleep architecture toward lighter, more fragmented sleep, suppress slow-wave sleep, and can alter circadian timing.
Understanding how stress and anxiety trigger autoimmune responses adds another layer. Chronic psychological stress dysregulates the HPA axis and immune signaling in ways that can lower the threshold for autoimmune activation in susceptible individuals.
Genetic Risk Factors for Autoimmune Sleep Disorders
Genetics in this field centers heavily on the HLA system, a set of genes on chromosome 6 that encodes proteins used by the immune system to distinguish self from non-self. These genes vary enormously between individuals, and certain variants load the dice for specific autoimmune conditions.
In narcolepsy type 1, the HLA association is one of the strongest seen in any complex disease. The HLA-DQB1*06:02 allele is present in over 98% of narcolepsy-cataplexy patients across multiple ethnic groups — European, Japanese, African-American populations — suggesting a universal mechanism rather than a population-specific quirk.
Carrying the allele doesn’t guarantee narcolepsy; the population prevalence of the allele is roughly 25% in Europeans, while narcolepsy affects only about 1 in 2,000 people. But its near-universal presence in affected individuals points squarely at the immune system as the mediating mechanism.
HLA Genetic Risk Factors Associated With Autoimmune Sleep Disorders
Disorder Associated HLA Allele Estimated Relative Risk Populations with Confirmed Association
Narcolepsy Type 1 HLA-DQB1*06:02 >200-fold vs. non-carriers European, Japanese, African-American
Narcolepsy Type 1 HLA-DQA1*01:02 High (in linkage with DQB1*06:02) European, Japanese
Kleine-Levin Syndrome HLA-DQB1*02 Modest (data limited) European
Anti-IgLON5 disease HLA-DRB1*10:01, HLA-DQB1*05:01 Elevated (small cohort data) European
Autoimmune Encephalitis (general) Variable by antibody type Moderate Mixed populations
What Are the Symptoms of Autoimmune Sleep Disorders?
The symptom picture shifts depending on which part of the sleep system is targeted, but several patterns appear consistently across conditions.
Excessive daytime sleepiness is the most common presenting complaint, not ordinary tiredness but an overwhelming, irresistible pressure to sleep that strikes at inappropriate times. Eating, driving, mid-conversation.
Patients often describe it as a physical force rather than a preference.
Cataplexy, when present, is diagnostic in character: sudden, emotion-triggered muscle weakness ranging from a jaw drop or knee buckle to a complete collapse, while the person remains conscious throughout. It’s one of the most bizarre and underdiagnosed symptoms in medicine.
Sleep paralysis and hypnagogic hallucinations, the inability to move at sleep onset or awakening, often accompanied by vivid, realistic visions or sensations, are experienced by many people without narcolepsy, but in narcolepsy they’re more frequent and more distressing.
Cognitive symptoms are common and often the most disabling in daily life. The autoimmune-related brain fog that accompanies these conditions goes beyond sleepiness; it involves genuine deficits in processing speed, working memory, and word-finding that don’t fully resolve with stimulant treatment.
Autoimmune encephalitis adds psychiatric symptoms, paranoia, hallucinations, personality change, to the mix, and these often dominate the early clinical picture before the sleep disturbance becomes apparent. Understanding the connection between autoimmune disease and mental illness matters here, because patients presenting to psychiatry with new-onset psychosis in their 20s or 30s may have an encephalitis diagnosis missed for months.
Night sweats and thermoregulatory disturbances are worth noting too.
Night sweats during illness have immunological roots, and in autoimmune conditions involving hypothalamic dysfunction, temperature dysregulation during sleep is not unusual.
How Do Doctors Diagnose Autoimmune-Related Sleep Disorders?
Diagnosis is often a long, frustrating process, partly because these conditions are rare, partly because the symptoms overlap substantially with more common disorders, and partly because the right tests aren’t always ordered.
The core diagnostic workup for narcolepsy combines two studies. Polysomnography (an overnight sleep study) establishes baseline sleep architecture and rules out other disorders, particularly sleep apnea, which causes daytime sleepiness through a completely different mechanism.
The multiple sleep latency test (MSLT), conducted the following day, measures how quickly a person falls asleep across five 20-minute nap opportunities. Falling asleep in under 8 minutes on average, with REM sleep appearing in two or more naps, is the electrophysiological signature of narcolepsy.
CSF hypocretin measurement is the definitive test when narcolepsy type 1 is suspected: levels below 110 pg/mL are diagnostic. HLA typing adds supporting evidence but can’t confirm or exclude the diagnosis on its own given how common the risk alleles are in the general population.
For autoimmune encephalitis, antibody panels in both serum and cerebrospinal fluid are essential, serum alone misses a meaningful proportion of cases.
MRI may show signal changes in limbic regions, though it’s often normal early in the disease. EEG frequently shows diffuse slowing or, in limbic encephalitis, characteristic patterns.
Accurate diagnosis depends on recognizing how each condition presents. Mapping each sleep disorder to its defining symptoms is the first step, and the one most often skipped when clinicians default to common explanations for daytime sleepiness.
The differential is substantial. Chronic sleep deprivation mimics hypersomnolence. Depression causes fatigue and disrupted sleep. Obstructive sleep apnea causes exactly the same pattern of morning fog and afternoon crashes as narcolepsy. The distinguishing features matter, and getting them wrong delays treatment by years.
Treatment Options for Autoimmune Sleep Disorders
Treatment has two parallel goals: suppress the immune attack, and manage the symptoms it’s caused. These are not always the same problem.
Immunotherapy is the most logical intervention when an active autoimmune process is identified. For autoimmune encephalitis, intravenous immunoglobulin (IVIG) and plasma exchange are first-line acute treatments.
Corticosteroids follow. For refractory cases, rituximab (which depletes B cells) or cyclophosphamide may be used. The earlier immunotherapy is started, the better the outcomes, delay allows more neuronal damage to accumulate, some of which may be irreversible.
For narcolepsy type 1, the timing problem is fundamental: by the time symptoms appear and a diagnosis is made, most of the hypocretin neurons are already gone. Immunotherapy at that stage has shown limited benefit in most cases, though there’s ongoing research into whether early intervention in newly diagnosed patients, within weeks of onset, might preserve some neurons.
Symptomatic treatment remains the mainstay for established narcolepsy. Sodium oxybate (GHB) taken at night consolidates nighttime sleep and substantially reduces cataplexy and daytime sleepiness, it’s the most effective pharmacological option currently available.
Wake-promoting agents (modafinil, armodafinil) and stimulants (methylphenidate, amphetamines) address daytime sleepiness. Antidepressants at low doses suppress REM sleep and reduce cataplexy.
A newer agent, pitolisant, acts on histamine receptors to promote wakefulness without the scheduling restrictions of controlled substances. Low-sodium oxybate formulations (Lumryz, Xywav) have improved tolerability for some patients.
Various sleep aids for autoimmune conditions can help with symptom management under medical supervision, though they work best as part of a broader treatment plan rather than as standalone solutions.
Lifestyle adaptations matter more than they’re usually given credit for.
Scheduled naps, two brief naps timed strategically across the day, can reduce total stimulant requirements and improve functioning in narcolepsy. Consistent sleep timing, avoiding alcohol, and managing how sickness disrupts sleep architecture all contribute to baseline stability.
Living With an Autoimmune Sleep Disorder
The practical reality is harder than the clinical description suggests.
Narcolepsy, for instance, isn’t just sleepiness. It’s the constant calculation of when it’s safe to drive. It’s explaining to an employer why you fell asleep in a meeting. It’s managing cataplexy, learning which emotions to suppress in public because laughing too hard might drop you to the floor.
The social and occupational consequences accumulate alongside the neurological ones.
Comorbid sleep disorders in chronic illness are common and complicate management. A narcolepsy patient who also develops sleep apnea has competing treatment demands. Someone with autoimmune encephalitis may recover their sleep architecture only to struggle with residual cognitive symptoms and anxiety.
The psychological dimension is real. The mind-body connection in autoimmune conditions works both ways: living with an unpredictable, stigmatized condition increases psychological stress, which in turn influences inflammatory tone.
Many people with autoimmune sleep disorders also experience autonomic nervous system dysregulation that affects heart rate, blood pressure, and temperature control during sleep, adding further complexity.
Support groups, particularly condition-specific ones like those organized by the Narcolepsy Network or Wake Up Narcolepsy, offer something clinical care often can’t: contact with people who understand the day-to-day reality. Online communities have expanded access significantly for people in areas with limited specialist coverage.
Autoimmune sleep disorders invert the usual disease logic. Most autoimmune conditions cause pain or organ damage that sends people to a doctor. Here, the attack targets the invisible architecture of consciousness itself, the circuits deciding when you’re awake, dreaming, or paralyzed, meaning the destruction can be nearly complete before anyone thinks to look for an antibody.
The Role of Neurological Sleep Disorders in the Broader Autoimmune Picture
Sleep disturbances don’t exist in isolation. For many people with autoimmune conditions, sleep is the canary in the coal mine, deteriorating before other symptoms become obvious, and improving before other markers respond to treatment.
Neurologically driven sleep disorders share important features with autoimmune presentations: disrupted circadian rhythms, REM abnormalities, and impaired restorative sleep stages. The distinction between a neurological and autoimmune cause often lies in the antibody panel and the treatment response, not in the sleep study itself.
This matters for research as well as clinical practice.
As antibody testing becomes more accessible and the list of recognized pathogenic antibodies grows, conditions currently labeled “idiopathic”, meaning we don’t know the cause, will likely split into subgroups, some of them autoimmune, some not. Idiopathic hypersomnia may well be that territory already.
The broader picture also includes how different sleep disorder categories overlap with autoimmune mechanisms, an area where clinical sleep medicine and neuroimmunology are increasingly converging.
Promising Signs: When Treatment Works
Early immunotherapy, In autoimmune encephalitis, starting IVIG or plasma exchange within weeks of symptom onset significantly improves outcomes, including full sleep-wake cycle restoration in some patients.
Sodium oxybate for narcolepsy, Reduces both cataplexy frequency and daytime sleepiness; many patients achieve substantial functional improvement within weeks of reaching therapeutic dosing.
Scheduled napping, Strategic 15–20 minute naps timed across the day can reduce reliance on stimulant medication and improve alertness in narcolepsy.
Condition-specific support, Engagement with patient organizations correlates with better disease self-management and reduced diagnostic delay in future patients.
Warning Signs That Require Urgent Evaluation
Rapidly progressive psychiatric symptoms with sleep disruption, New-onset psychosis, personality change, or confusion combined with sleep-wake reversal in a young person warrants antibody testing for autoimmune encephalitis, not just psychiatric admission.
Cataplexy in any form, True emotion-triggered muscle weakness is not explained by other common conditions and requires urgent sleep medicine evaluation.
Total or near-total insomnia, Severe insomnia combined with neuromyotonia, hallucinations, or autonomic instability should prompt testing for Morvan’s syndrome or related encephalitides.
Recurrent weeks-long hypersomnia episodes, Episodic hypersomnia with behavioral changes strongly suggests Kleine-Levin Syndrome and shouldn’t be attributed to depression without investigation.
When to Seek Professional Help
A bad night’s sleep is normal. What’s described below is not.
Seek a sleep medicine specialist or neurologist promptly if you experience:
- Irresistible daytime sleepiness that doesn’t improve with more nighttime sleep and interferes with work, driving, or daily tasks
- Any episode of emotion-triggered muscle weakness, a jaw drop, knee buckle, or collapse while conscious
- Sleep paralysis occurring frequently, particularly with vivid hallucinations
- Sleep-wake reversal or complete inability to maintain normal sleep timing despite trying
- Recurrent episodes of hypersomnia lasting days to weeks, separated by periods of complete normality
- New neurological or psychiatric symptoms, confusion, hallucinations, seizures, appearing alongside severe sleep disturbance
Seek emergency evaluation immediately for:
- Acute confusion or inability to recognize people or surroundings combined with sleep disturbance
- New-onset seizures with any sleep or cognitive changes
- Psychiatric crisis, paranoia, hallucinations, or dangerous behavior, particularly with recent infection or fever
If you’re in crisis, contact the 988 Suicide & Crisis Lifeline by calling or texting 988 (US). For neurological emergencies, go to the nearest emergency room or call emergency services.
