Schizophrenia: Symptoms, Causes & Treatment

Schizophrenia is a chronic and relatively serious mental disorder that affects how a person thinks, perceives reality, feels, and behaves. It is among the most misunderstood mental disorders in society, as it is sometimes wrongly confused with split personality, whereas it is in fact a disorder of thought and perception organization, not a split in personality.

Schizophrenia symptoms are divided into positive symptoms (in excess of normal) such as delusions (firmly held false beliefs), hallucinations (hearing voices or seeing things that are not there), and disorganized speech and thinking, and negative symptoms (a deficit) such as social withdrawal, reduced speech, flattened emotions, and low motivation, in addition to difficulties with concentration and memory. The illness often begins in late adolescence or the early twenties.

It is important to correct the stereotype: the vast majority of people with schizophrenia are not violent and may in fact be more vulnerable to harm than others, and they deserve understanding and support rather than stigma. Schizophrenia is a medical illness with a biological basis and is treatable: antipsychotic medications effectively control symptoms, and psychotherapy, rehabilitation, and family and social support aid recovery and integration. Adherence to treatment and regular follow-up are the keys to controlling the illness and reducing relapses.
