- Schizophrenia is a serious mental disorder with disturbed thinking, perception, mood, and behaviour.
- Main symptoms are delusions, hallucinations, disorganized speech, abnormal behaviour, and negative symptoms.
- Symptoms must last 1 month, with overall disturbance for 6 months for diagnosis.
- Delusions are false beliefs (e.g., persecution, control, grandeur).
- Hallucinations are false perceptions; hearing voices is most common.
- Patients may show flat/inappropriate emotions and abnormal motor behaviour (e.g., catatonia).
- Social withdrawal is common, and cultural factors are important in diagnosis.

Introduction
Schizophrenia represents a group of psychoses marked by severe distortions in thought, perception, mood, bizarre behaviour, and social withdrawal. DSM-IV-TR identifies five key symptoms, including delusions, hallucinations, disorganised speech, disorganised or catatonic behaviour, and negative symptoms like reduced normal functions.
CISCE: Class 12
Definition: Schizophrenia
Schizophrenia is a label given to a group of psychoses in which deterioration of functioning is marked by severe distortion of thought, perception, and mood; by bizarre behaviour and by social withdrawal.
CISCE: Class 12
Thought and Language Disorders
Thought and Language Disorders - Delusions
- Delusions are strongly held false beliefs that have no basis in reality and are not culturally accepted.
- Delusions of persecution involve believing that others are trying to harm or conspire against the person.
- Delusions of control include feelings that thoughts are being inserted, removed, broadcast, or controlled by outside forces.
- Other types include delusions of reference, grandeur, guilt, illness, or beliefs that nothing exists (nihilistic).
Thought and Language Disorders - Speech Issues
- Speech jumps between unrelated ideas and becomes hard to understand.
- Speech is grammatically correct but gives very little meaningful information.
- New and meaningless words are created and used in conversation.
- Words are linked together because they rhyme or sound similar, not because they make sense.
- Speech becomes completely disorganized and incoherent.
CISCE: Class 12
Definition: Hallucinations
Schizophrenics perceive things that are not there. Such perceptions occurring in the absence of any appropriate external stimulus are called hallucinations.
CISCE: Class 12
Perception Disorders
- Hallucinations occur as perceptions without external stimuli, most commonly auditory, like voices conversing or commenting derogatorily.
- Visual hallucinations rank second in frequency, followed by those in other senses like touch or smell.
CISCE: Class 12
Mood Disorders
- Blunted affect shows minimal emotional expression in patients.
- Flat affect displays no emotion whatsoever.
- Inappropriate affect mismatches emotions to situations, such as giggling over painful memories or anger at gifts.
CISCE: Class 12
Definition: Stereotyped Acts
The act of engaging in purposeless behaviours repetitively over long periods of time is called stereotyped acts.
CISCE: Class 12
Motor Behaviour Disorders
- Stereotyped acts involve repetitive, purposeless behaviours like head rubbing or paper tearing over long periods.
- Catatonic stupor features patients remaining mute and immobile for days.
- Catatonic rigidity resists limb movement by others, while flexibility allows excessive bending.
- Echolalia mimics others' speech, echopraxia copies their movements, and negativism prompts opposite actions to requests.
CISCE: Class 12
Social Withdrawal
- Social withdrawal begins as emotional detachment and lack of interest in external activities or people.
- Patients gradually isolate from their environment and social interactions.
CISCE: Class 12
Cultural Factors
- DSM-IV emphasises cultural influences, as some disorders like Koro appear only in Southeast Asia and Windigo among Native Americans.
- Cultural context shapes the form and direction of psychological disorders.
- DSM-V, recently published, further refines these classifications.
CISCE: Class 12
