ABSTRACT
Schizophrenia is still one of the most serious psychiatric disorders. With a lifetime prevalence of almost 1%, it is one of the world’s leading causes of chronic disability. The symptomatology can be divided into ‘positive’ and ‘negative’ symptoms. Positive symptoms include delusions, hallucinations and thought disorders. Negative or deficit symptoms include cognitive defects, emotional defects and deficits in energy, language and contact.
