Schizophrenia is a chronic mental disorder characterized by a detachment from reality and a range of symptoms, including:
- Delusions: Delusions are fixed, false beliefs that persist despite contradictory evidence or reasoning. Examples include delusions of persecution, grandeur, or reference.
- Hallucinations: Hallucinations are sensory perceptions that occur without an external stimulus. The most common type is auditory hallucinations (hearing voices). Other types include olfactory (smelling), tactile (touching), and visual hallucinations.
- Disorganized Thinking and Speech: Disorganized thinking and speech (dyslogia) are characterized by incoherent thoughts, illogical speech patterns, and difficulty communicating effectively. This may manifest as derailment (jumping from one topic to another), incoherence (nonsensical speech), or poverty of speech (lack of content).
- Disorganized Behavior: Disorganized behavior (catatonia) includes inappropriate or purposeless actions that are often bizarre or illogical. Examples include catatonia (lack of movement or excessive movement), echolalia (repeating others’ words), and echopraxia (imitating others’ actions).
- Negative Symptoms: Negative symptoms are a reduction or loss of normal emotional and behavioral responses. They may include:
- Alogia (poverty of speech): Speaking little or not at all
- Affective flattening: Reduced emotional expression
- Avolition: Lack of motivation or initiative
- Anhedonia: Inability to experience pleasure
- Asocial withdrawal: Social isolation and withdrawal from social activities
