Symptoms of Schizophrenia

Schizophrenia is a serious but treatable mental health condition. Its hallmark features are persistent disturbances in perception, thinking, emotions, and behaviour. These symptoms affect daily functioning, relationships, and overall quality of life. Not every patient experiences all symptoms, but persistent impairment lasting more than a month requires professional attention.

1. Hallucinations

Hallucinations are among the most common symptoms:

• Auditory hallucinations: Hearing voices that comment, criticise, or command.
• Visual hallucinations: Seeing images or figures that are not real.
• Tactile hallucinations: Feeling sensations that have no physical source.

Hallucinations blur the boundary between reality and imagination, causing distress and behavioural changes.

2. Delusions

Delusions are fixed false beliefs, resistant to correction:

• Persecutory delusions: Belief of being harmed, monitored, or followed.
• Grandiose delusions: Belief of having special powers, status, or mission.
• Referential delusions: Belief that everyday events or media messages carry personal meaning.

Delusions shape behaviour and relationships, often leading to fear or conflict.

3. Disorganised Thinking and Speech

Patients may show:

• Incoherent or fragmented speech.
• Difficulty organising thoughts, disrupting communication.
• Severe cases may present with “word salad,” where speech loses logical structure.

These impairments affect learning, work, and social functioning.

4. Abnormal Behaviour

Behavioural changes include:

• Odd or illogical behaviours: Talking to oneself, unusual postures, ritualistic actions.
• Social withdrawal: Avoiding interactions and isolating from others.
• Decline in self-care: Neglecting hygiene, irregular eating, lack of motivation.
• Changes in activity: Either slowed movements or excessive restlessness.

Such behaviours are often noticed first by family or colleagues.

5. Negative Symptoms

Negative symptoms reflect reductions in emotional and motivational capacity:

• Blunted affect: Reduced emotional expression and lack of interest.
• Avolition: Loss of motivation to engage in daily tasks.
• Alogia: Reduced speech output or lack of initiative in conversation.

These symptoms are persistent and significantly lower quality of life.
