What is Psychosis?
Psychosis is a symptom of serious mental disorders which affect thoughts, feelings, and behaviours. People with psychosis have an altered perception and sense of reality with a breakdown in communication.
According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) there are five characteristic symptom dimensions in schizophrenia.
- Disorganized Speech
- Disorganized Behavior
- Negative Symptoms
Schizophrenic psychoses are aetiologically complex disorders that affect about 1-2% of the population during their lifetime. The clinical symptom presentation varies greatly between psychosis patients with identical diagnoses and there is a marked inconsistency in findings regarding associated biological disease markers, including structural and functional neuroimaging substrates. Accordingly, it has been suggested that psychoses are best conceptualized as a set of heterogeneous conditions with multiple distinct underlying pathophysiological processes that give rise to the diverse psychopathological symptoms. The heterogeneity of the psychosis phenotype is being regarded as a major obstacle in the identification of biological mechanisms.
