Why is schizophrenia split into the categories negi tive and positive?

Schizophrenia is divided into negative and positive categories to better describe and understand its diverse symptoms. Positive symptoms, such as hallucinations and delusions, represent an excess or distortion of normal functions. Negative symptoms, like apathy and social withdrawal, reflect a reduction or absence of normal emotional and behavioral functions. This classification aids in diagnosis, treatment planning, and enhancing our comprehension of the disorder's complexity.
