Schizophrenia

What is Schizophrenia?

Schizophrenia is a disabling psychiatric condition that affects about 1 in 100 people worldwide and is marked by psychotic symptoms, reduced motivation and expressiveness, and problems with thinking.^[1] It is a medical illness that needs psychiatric treatment. The effect on daily life varies widely from person to person.^[1]

Common symptoms

Symptoms fall into three groups: positive, negative and cognitive.^[1]

• Positive symptoms: hallucinations such as hearing voices, delusions (fixed false beliefs), and disorganized speech or behavior
• Negative symptoms: reduced motivation, reduced emotional expression, loss of pleasure and social withdrawal
• Cognitive symptoms: problems with memory, attention, planning and processing speed

Negative and cognitive symptoms strongly affect work and relationships and often respond poorly to antipsychotic medication.^[1] Symptoms usually begin in late adolescence or early adulthood and may come on gradually or suddenly.

Causes and risk factors

No single cause is known. Schizophrenia is thought to arise from many genes acting together with early-life and environmental factors.^[2] Listed risk factors include family history, birth complications, maternal infection or severe malnutrition during pregnancy, childhood trauma, social isolation and cannabis use.^[1]

How it is diagnosed and treated conventionally

A psychiatrist diagnoses schizophrenia from a detailed history and mental status examination, after ruling out other psychiatric and medical causes of psychosis.^[1]

The mainstay of treatment is antipsychotic medication, which works by blocking dopamine D2 receptors.^[2] Cognitive behavioral therapy has relatively small effects on symptoms but is widely used.^[3] Family education, rehabilitation, community support and hospital care during severe episodes are also part of conventional care.

Why Schizophrenia calls for a whole-person approach

Medication treats the psychotic symptoms, but daily life with schizophrenia also depends on sleep, stress, physical health and the symptoms that medication does not reach well. These are the areas where supportive care may help.

Supportive care does not treat schizophrenia itself. It belongs only alongside psychiatric treatment, with your treating team aware of it.

Sleep

Sleep problems are very common. A systematic review found that about half of patients with psychosis had insomnia, and that disrupted sleep predicted paranoia and hallucinations. In the psychological treatment studies reviewed, improving sleep may have modestly eased psychotic experiences.^[4]

Stress and early adversity

Stress and trauma are linked to the illness. A meta-analysis of case-control, prospective and cross-sectional studies found that people exposed to childhood adversity were nearly three times as likely to have psychosis.^[5] Psychosocial stressors are also thought to contribute to the onset of positive symptoms.^[2]

Physical health and medication side effects

People with schizophrenia live an estimated 13 to 15 years less on average, and poor diet, weight gain, smoking and substance use contribute.^[1] Antipsychotics differ in their effects on weight, cholesterol and blood sugar, with olanzapine and clozapine showing the largest changes in a network meta-analysis of 100 trials.^[6] These are reasons to talk with your prescriber, not to stop medication.

Negative and cognitive symptoms

Low motivation and thinking problems are a major source of disability and are poorly served by current drugs.^[1] This is one reason researchers look at additional approaches, including exercise and complementary therapies.

Acupuncture as supportive care in Schizophrenia

What the research shows

Acupuncture has been studied in schizophrenia mostly as an addition to antipsychotic medication, and the evidence is low quality. A Cochrane review of 30 trials, all at moderate risk of bias, concluded that limited evidence suggests acupuncture may have some effect on global and mental state, and called for larger, better-designed studies.^[7]

A 2026 meta-analysis of 55 trials (4,256 participants) found that acupuncture added to standard-dose antipsychotics improved overall symptom scores compared with antipsychotics alone, with low-certainty evidence. In two trials with sham acupuncture, real acupuncture was not clearly better than sham, so the specific effect of needling is uncertain. Acupuncture with a reduced antipsychotic dose showed little to no difference from standard-dose medication, with very low certainty.^[8] This does not support lowering medication.

One sham-controlled trial of 60 patients with persistent auditory hallucinations on risperidone found a clinical response in 43% with real electroacupuncture and 13% with sham over six weeks.^[9] It is a single small study and needs confirmation.

For sleep, a trial of 96 patients with schizophrenia compared six weeks of shallow needling with a sleeping pill. Sleep scores improved to a similar degree in both groups, and side effects were lower with needling.^[10] A systematic review likewise found limited evidence for schizophrenia symptoms but suggested acupuncture may improve quality of life, particularly sleep, in psychiatric patients.^[11]

How acupuncture may work

How acupuncture might help in schizophrenia is not established. Brain imaging research cited in one review suggests that needling changes activity in a network linked to sleep and emotion, which could explain better sleep and quality of life.^[11] Because real acupuncture did not clearly beat sham in the pooled sham-controlled trials, part of the benefit seen in the other trials may not be specific to needling.^[8]

What treatment involves

A session uses fine, sterile, single-use needles placed for about 20 to 40 minutes, usually over a course of several visits with reassessment. For a condition like this, we ask that you are under a psychiatrist's care for it and that your treating team knows you are receiving complementary care. Serious problems from acupuncture are rare. In prospective studies, about 9 in 100 patients had a minor reaction such as brief bleeding or soreness at a needle site, and serious events occurred in about 1 in 10,000 patients.^[12] Tell the practitioner about all medicines, bleeding problems, pregnancy, a pacemaker or a seizure disorder.

Ayurvedic medicine as supportive care in Schizophrenia

The Ayurvedic view

Classical Ayurveda describes severe mental illness with confusion, false perceptions and disturbed behavior under the heading of unmada, a disorder of the mind linked to disturbance of the doshas. These are traditional categories, not biomedical diagnoses, and they do not replace a psychiatric diagnosis.

Therapies that may be used

Supportive Ayurvedic care for someone under psychiatric treatment focuses on routine:

• Regular times for sleeping, waking and meals
• Calming practices such as gentle oil massage
• Selected herbs such as ashwagandha, only with the psychiatrist's agreement

Panchakarma cleansing procedures, fasting and strong purgative or emetic therapies are not appropriate during an episode of illness, in pregnancy, or in frailty. In one trial, an Ayurvedic formula called brahmyadiyoga commonly caused nausea and vomiting.^[13]

What the research shows

The evidence for Ayurveda is limited and comes from small trials. A Cochrane review found only three small, short trials (250 participants in total). Results against placebo were mostly unclear apart from one formula assessed with Ayurvedic criteria, and patients given herbs were more likely to show no improvement than those given the antipsychotic chlorpromazine. The authors concluded that Ayurvedic medicine may have some effect but has been tested only in a few small pioneering trials.^[13]

Ashwagandha (Withania somnifera) has been tested as an add-on. In a 12-week placebo-controlled trial of 66 patients with a recent worsening of symptoms, a standardized extract added to antipsychotics reduced negative, general and total symptoms and perceived stress, but not positive symptoms. Drowsiness, stomach discomfort and loose stools were more common.^[14] A network meta-analysis of nutritional and plant supplements found a benefit for Withania in acute-phase trials at low risk of bias, but rated the overall quality of evidence in this field as low to very low.^[15]

Herbal medicine as supportive care in Schizophrenia

Herbs and formulas that have been studied

The herbal products studied most in schizophrenia are Chinese herbal formulas, such as Wendan decoction, and Ginkgo biloba extract, nearly always as additions to antipsychotic medication.^{[16, 17]}

What the research shows

The evidence is not enough to support using herbs instead of antipsychotics. In a Cochrane review of Chinese herbal medicine, the one trial comparing herbs with an antipsychotic favored the medication, and combining herbs with antipsychotics gave some benefit. The review noted that most trials did not truly test traditional Chinese medicine.^[18]

A Cochrane review of Wendan decoction (15 trials, 1,437 participants) found it was used mostly as an add-on, with better short-term global and mental state than antipsychotics alone. In two trials against an antipsychotic, it showed no difference in global state. The authors said the evidence was not high quality.^[16]

A meta-analysis of eight placebo-controlled trials (1,033 patients) found that Ginkgo biloba extract added to antipsychotics improved total and negative symptoms in chronic schizophrenia. All trials were done in China, and the authors said the safety of ginkgo needs more evidence.^[17]

Safety and herb-drug interactions

Herbal safety is a serious concern in schizophrenia. In a review of 147 adverse events from combining herbal products with psychiatric drugs, ginseng, rhodiola, ginkgo and milk thistle were the most frequent causes. Events included heart rhythm problems when ginseng was taken with haloperidol and bleeding with ginkgo and antidepressants.^[19]

Tell your psychiatrist and pharmacist before starting any herb or supplement. This matters most with clozapine, lithium, and medicines for mood, seizures or sleep, and during pregnancy or breastfeeding. Liver disease also calls for extra care. Product quality matters too: in one study, about one fifth of Ayurvedic medicines bought online contained detectable lead, mercury or arsenic.^[20] Herbs should come from tested sources and be prescribed individually by a qualified practitioner.

Translating traditional medicine into modern biological language

The links drawn here are interpretation, not equivalence. Chinese medicine describes disturbed states of mind with images such as phlegm clouding the mind, and Ayurveda speaks of disturbed doshas affecting the mind. Researchers instead measure sleep quality, stress responses and brain network activity.^{[4, 11]}

In the ashwagandha trial, for example, stress scores improved more than with placebo, while blood markers of inflammation did not differ significantly between groups.^[14] No study has shown that a traditional pattern corresponds to a specific biological process in schizophrenia.

How this care fits with your medical care

Supportive care is meant to be given after the condition is under medical management and with your treating team's knowledge. Keep taking prescribed medication exactly as directed and keep all psychiatric appointments. Never reduce or stop antipsychotic medication because you feel better, and do not change a dose because of anything you read here. Talk with your psychiatrist first.

Please bring your diagnosis, your psychiatrist's contact details and a full list of medicines and supplements. We ask that your treating team knows you are receiving complementary care. We do not diagnose or manage schizophrenia.

When to seek urgent medical care

New or worsening psychotic symptoms need prompt psychiatric assessment, and the lifetime risk of suicide in schizophrenia is estimated at 5% to 10%.^[1]

• Thoughts of suicide or self-harm, or thoughts of harming someone else
• New or worsening voices, unusual beliefs or fear that others are trying to harm you
• Not eating, drinking, sleeping or caring for oneself
• Sudden confusion, especially with fever, severe headache or a seizure
• Stopping antipsychotic medication, or a return of symptoms after missed doses
• High fever with stiff muscles while taking antipsychotic medication

Call 911 or go to the nearest emergency department for any of these. In the United States, you can also call or text 988 to reach the Suicide and Crisis Lifeline.
