Understanding Schizophrenia: Symptoms, Diagnosis, and Treatment
- Psychosis is an abnormal mental state where reality is indistinguishable from unreality, often linked to primary psychosis in psychiatry.
- Schizophrenia symptoms are categorized into positive (present in schizophrenia) and negative (absent in schizophrenia) symptoms, forming diagnostic criteria.
- Positive symptoms include hallucinations (commonly auditory), delusions (paranoid and persecutory), disorganized behavior, disorganized speech, and negative symptoms.
- Hallucinations in schizophrenia are typically auditory, clear, and distinct, often involving critical or demeaning voices from outside the patient's head.
- Delusions in schizophrenia are fixed false beliefs, often paranoid or persecutory, involving ideas of reference and control by external forces.
- Thought disorganization in schizophrenia is evident in speech, behavior, and thought coherence, leading to clang associations, neologisms, echolalia, and perseveration.
- Negative symptoms in schizophrenia include affective deficits, ambivalence, alogia, anhedonia, and asociality, impacting emotional expression, decision-making, speech, pleasure, and social interactions.
- Schizophrenia diagnosis requires two or more symptoms from the mnemonic HDBS Network (hallucinations, delusions, disorganized behavior, disorganized speech, negative symptoms) for at least six months.
- Schizophrenia onset is typically in early adulthood, more common in men, with symptoms showing signs even in childhood, leading to lifelong functional impairment and recurrent exacerbations.
- Treatment for schizophrenia involves antipsychotic medications to reduce positive symptoms, psychotherapy like CBT for psychosis, and may require hospitalization for severe cases, with poor outcomes often leading to social isolation, homelessness, and reduced life expectancy.

Duration of psychosis predicts schizophrenia prognosis and treatment
- Two-thirds of patients with schizophrenia progress from a psychotic disorder, emphasizing the importance of the duration of psychosis in predicting outcomes, with a longer period indicating a worse prognosis. Delusional disorder, characterized by firm delusions without other schizophrenia symptoms, can significantly impact patients' lives, leading to social and occupational dysfunction. Treatment options like antipsychotics offer limited benefits, while psychotherapy, such as CBT, can help patients manage the impact of their delusions on daily life.
