Schizophrenia: Definition, Causes, Diagnosis, and Treatment

Accurate diagnosis is essential for effective treatment and long term stability. Age is also an important factor, as symptoms most commonly emerge between the ages of sixteen and thirty, with males often experiencing earlier onset than females. Understanding these influences reinforces that schizophrenia does not result from a single event, decision, or personal weakness. Even as diagnostic practices have evolved, these classifications continue to offer helpful context for understanding the different ways schizophrenia can present. Historically, schizophrenia was divided into subtypes to reflect differences in symptom presentation.

Newer medications are often preferred due to improved tolerability, though they require careful monitoring for metabolic effects such as weight gain or changes in blood sugar . Clinicians often gather information from family members or caregivers and assess for co occurring conditions such as mood disorders or substance use disorders. Environmental and experiential factors can further increase risk, especially when combined with genetic vulnerability .

Pharmacological Treatment of Patients with Alcohol Use Disorder (

We did not include two outcomes that are sometimes evaluated. For psychosocial and nonpharmacological interventions, we limited to the most commonly-used interventions relevant to United States practices. While the success of any given treatment depends on the balance of benefit and harm, specific treatment considerations will vary across the lifespan.

What are the ‘positive symptoms’ of schizophrenia?

Electroconvulsive therapy (ECT) is not often used for the treatment of schizophrenia but may be considered when other treatments have not been effective. A key worker such as a community psychiatric nurse or psychiatric social worker is usually allocated to co-ordinate the care for each person with schizophrenia. Therefore, as with everyone else in the population, people with schizophrenia are encouraged to adopt a healthy lifestyle. Such things as smoking, lack of exercise, obesity and an unhealthy diet Grief and bereavement resources at CSUSM are more common than average in people with schizophrenia. Art therapyThis has been found to be helpful, particularly for negative symptoms. Family interventionThis may be offered and consists of about 10 therapy sessions for relatives of patients with schizophrenia.

• In comparison with usual care, most of the psychosocial interventions to treat schizophrenia reviewed were more effective in improving two or more outcomes, including nontargeted but patient-important outcomes.

The first-generation antipsychotic drugs act mainly by blocking dopamine D2 receptors in the brain. Some phenothiazine antipsychotics (e.g., periyazine) have been proven to cause fewer extrapyramidal effects than others, which is thought to be correlated with their antagonist properties to muscarinic receptors. Furthermore, block of 5-HT2A receptor appears to improve the negative symptoms on account of enhancing the release of both dopamine and glutamate in the mesocortical circuit.

Staying on medication can significantly reduce the risk that you will experience any further relapses. There is a high risk of relapse if you stop taking your medication within 1 to 2 years of starting it. Many people want to know how long they will have to take medication, and if they will be able to stop taking it in the future.

In this and the following sections, the most common adverse effect of antipsychotics are mentioned. Maintaining the balance between dopamine and acetylcholine was also the rationale behind the use of benztropine, the muscarinic antagonist, to reduce extrapyramidal side effects of neuroleptics. These are serotonin 5-HT2A and 5-HT1A receptors that play an important role in the treatment of schizophrenia. Sudden cessation of administration of antipsychotic drugs may result in a rapid onset of psychotic episode, that are different from the underlying illness .
