Schizophrenia

Schizophrenia is a mental health condition characterized by changes in how a person thinks, perceives their surroundings, and expresses emotion. Those affected commonly experience hallucinations—perceptions without a real stimulus—and delusions, fixed false beliefs with no basis. Speech and the connection between thoughts can also become fragmented.

The condition typically begins in late adolescence to early adulthood, and appears more often in men than women. It is a long-term condition, but its severity varies widely between individuals: some recover and maintain work and family life, while others require ongoing support.

Symptoms

Symptoms are generally divided into two categories. Positive symptoms involve new additions: hearing voices, paranoid or persecutory beliefs, and disorganized speech. Negative symptoms involve diminishment of normal function: emotional flattening, reduced speech, social withdrawal, and loss of motivation. Difficulties with memory, attention, and planning also occur.

Causes and risk factors

There is no single cause. Research suggests an interaction between genetic and environmental factors. Those with close relatives who have the condition face elevated risk. Other associated factors include pregnancy and birth complications, psychological stress, and use of certain substances, particularly cannabis in younger age.

Diagnosis and treatment

No blood test or brain scan provides immediate diagnosis. Mental health specialists rely on interview, symptom history and duration, first ruling out other causes such as physical illness or medication effects. Treatment combines antipsychotic medication, psychological and social support, vocational training, and family involvement. Early intervention and ongoing care typically reduce relapse rates.

Society and language

Those with the condition often face stigma and misunderstanding, including the false assumption that they are more likely to be violent—when in fact they experience harm more often than others. Traditional Somali medical terminology such as 'waali' conflates different mental health conditions, making it harder to distinguish among different types of psychiatric illness.
