Understanding Schizophrenia
Schizophrenia is a complex and severe mental disorder that affects how a person thinks, feels, and behaves. People with schizophrenia may seem like they have lost touch with reality, which can be distressing for them and for their families and friends. The symptoms of schizophrenia can make it difficult to participate in usual, everyday activities, but effective treatments are available. Early intervention can significantly improve long-term outcomes.

Common symptoms
Symptoms vary in severity and presentation. Diagnosis is made only when they significantly affect daily life over time.
- Hallucinations (hearing or seeing things that aren't there)
- Delusions (strongly held false beliefs that are not supported by reality)
- Disorganized thinking and speech (e.g., switching topics erratically)
- Abnormal motor behavior (e.g., agitation, lack of response)
- Negative symptoms (e.g., reduced emotional expression, lack of motivation, social withdrawal)
Possible causes
Mental health conditions rarely have a single cause — they arise from a mix of biological, psychological and social factors.
- Genetics: Having a family history increases the risk.
- Brain chemistry and structure: Imbalance in neurotransmitters like dopamine and glutamate.
- Environment: Exposure to viruses, toxins, or malnutrition before birth.
- Substance use: Use of mind-altering drugs during teen years or young adulthood.
Risk factors
Certain factors may increase the likelihood of developing this condition:
- Family history of schizophrenia
- Pregnancy and birth complications
- Taking psychoactive or psychotropic drugs during teen years and young adulthood
How it is evaluated
Evaluation involves a comprehensive psychiatric assessment to observe behavior and symptoms, and a medical history to rule out other causes like substance abuse, medication side effects, or medical conditions.
When to seek help
People with schizophrenia often lack awareness that their difficulties stem from a mental disorder. It often falls to family or friends to get them help. Seek immediate psychiatric evaluation if a loved one experiences hallucinations, severe paranoia, or disorganized speech.
Evidence-based treatments
Treatment is highly individualised. A combination of therapy, medication and lifestyle support is usually most effective.
Antipsychotic Medications
Medication is the cornerstone of schizophrenia treatment. These drugs help control symptoms by affecting the brain neurotransmitter dopamine. Finding the right medication and dose can take time.
Psychosocial Interventions
Once psychosis recedes, psychological and social (psychosocial) interventions are important. These include individual therapy, social skills training, family therapy, and vocational rehabilitation.
