What is the difference between psychosis and schizophrenia?

Psychosis is a set of symptoms affecting the mind, where a person loses partial contact with reality. During a psychotic episode, a person's thoughts and perceptions are affected, and they may find it difficult to distinguish between what is real and what is not [1]. Schizophrenia, on the other hand, is a chronic and complex mental disorder characterized by recurring psychotic episodes, as well as other symptoms that affect thinking, feelings, and behavior. Psychosis can be a symptom of various mental illnesses, including schizophrenia, bipolar disorder, or severe depression, but it does not necessarily mean a diagnosis of schizophrenia [1].

Understanding Psychosis

Psychosis can affect anyone, and it is estimated that between 15 and 100 people out of every 100,000 develop psychosis each year. Symptoms of psychosis often begin in young adulthood, from late adolescence to the mid-twenties, but they can occur at any age [1].

Common symptoms of psychosis include hallucinations (such as hearing or seeing things that do not exist) and delusions (false beliefs, such as feeling that others are trying to harm them). Other symptoms may include incoherent speech or behavior inappropriate to the situation. Before psychosis fully emerges, warning signs may appear, such as suspicion or paranoid thoughts, difficulty thinking clearly, social withdrawal, unusual thoughts, neglect of personal hygiene, and sleep disturbances [1].

Psychosis as a Symptom of Schizophrenia

Schizophrenia is one of the disorders in which psychosis can appear as part of its symptoms. When diagnosing schizophrenia, other causes of psychosis are ruled out first. Schizophrenia is a complex disorder that involves a range of symptoms beyond just psychotic episodes, including difficulties in thinking, emotional expression, and daily functioning [1].

Causes of Psychosis

There is no single cause for psychosis; rather, it appears to result from a complex combination of genetic predisposition, differences in brain development, and exposure to stress or trauma. Psychosis can also be a symptom of other medical conditions such as geriatric diseases (such as Parkinson's and Alzheimer's), sleep deprivation, certain prescription medications, or alcohol and drug abuse [1].

Diagnosis and Treatment

Psychosis and schizophrenia are diagnosed by a qualified mental health professional (such as a psychiatrist or psychologist). Diagnosis involves a comprehensive assessment to rule out other causes for the symptoms [1].

Treatment for psychosis usually includes antipsychotic medications, which are available in various types and have varying side effects. It is important to work with a healthcare provider to determine the most effective medication with the fewest side effects. Treatment often also includes other elements such as individual or group psychotherapy, cognitive behavioral therapy, family support and education programs, medication management, and supported employment and education services [1].

Early treatment is crucial for achieving better outcomes. Studies indicate that people often suffer from psychotic symptoms for more than a year before receiving treatment. Reducing this duration of untreated illness can significantly improve the chances of recovery [1].

When to Seek Help?

If you are experiencing changes in behavior such as increased suspicion, difficulty thinking, social withdrawal, or hallucinations and delusions, or if you notice these symptoms in someone you know, and these symptoms start to worsen or do not disappear, it is important to contact a healthcare provider [1]. In life-threatening emergencies, such as suicidal thoughts or violent behavior, emergency assistance must be sought immediately [1].

One rare and serious side effect of some antipsychotic medications is Neuroleptic Malignant Syndrome, which is characterized by high fever, muscle stiffness, sweating, blood pressure instability, and altered mental status [3]. If these symptoms appear, immediate medical attention must be sought.
