Schizophrenia is a chronic and severe mental disorder that affects approximately one in every 100 people globally. It can cause hallucinations, delusions, and disordered thinking, making it difficult for individuals to distinguish between what is real and what is not. Despite common misconceptions, schizophrenia does not mean a "split personality" and is not caused by personal weakness.
In Malaysia, the Ministry of Health has expanded community-based mental health services to support individuals living with schizophrenia and their families. With proper treatment and support, many people with schizophrenia can manage their symptoms and lead productive, meaningful lives.
What Is Schizophrenia?
Schizophrenia is a complex brain 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 both the individual and their loved ones. The condition typically emerges in late adolescence or early adulthood, usually between the ages of 16 and 30.
The symptoms of schizophrenia are generally categorised into three groups: positive symptoms (additions to normal experience), negative symptoms (reductions in normal experience), and cognitive symptoms (problems with thinking and concentration).
Signs and Symptoms
Schizophrenia manifests differently in each person, but the following are common symptoms:
- Positive symptoms: Hallucinations (hearing or seeing things that are not there), delusions (fixed false beliefs), and disordered speech
- Negative symptoms: Reduced emotional expression, lack of motivation, social withdrawal, and reduced ability to experience pleasure
- Cognitive symptoms: Difficulty concentrating, impaired memory, and problems with decision-making
- Disorganised thinking and speech
- Strange or unusual motor behaviour
- Difficulty with daily functioning
The severity of symptoms can vary over time, with periods of worsening and improvement. Early treatment significantly improves long-term outcomes.
Causes and Risk Factors
The exact cause of schizophrenia is not known, but research suggests it results from a combination of genetic, brain chemistry, and environmental factors. Having a first-degree relative with schizophrenia increases the risk significantly, though most people with a family history will never develop the condition.
Brain imaging studies have shown differences in the brain structure and chemistry of people with schizophrenia. Imbalances in neurotransmitters, particularly dopamine and glutamate, are believed to play a central role. Prenatal complications, maternal infections during pregnancy, and childhood trauma have also been identified as potential risk factors.
Substance use, particularly cannabis and amphetamines during adolescence, may increase the risk of developing schizophrenia in genetically vulnerable individuals. Urban living and migration have also been associated with slightly higher rates of the condition.
Treatment and Management
Schizophrenia is a lifelong condition, but it can be effectively managed with appropriate treatment. Antipsychotic medications are the primary treatment and work by affecting dopamine pathways in the brain. These medications can significantly reduce positive symptoms and help prevent relapse.
Psychosocial interventions, including Cognitive Behavioural Therapy (CBT), social skills training, and supported employment, are important components of comprehensive treatment. Family psychoeducation helps families understand the condition and develop effective coping strategies.
Community-based rehabilitation programs in Malaysia provide ongoing support, including occupational therapy, vocational training, and social integration activities. Early intervention and consistent treatment adherence are key to improving outcomes.
