Excerpt
Schizophrenia is a serious and lifelong mental
disorder that affects 1% of the population worldwide. It
is characterized by a range of striking disturbances in mental functioning
that are conceptualized as signs and symptoms that can be grouped
into discrete categories. These include symptoms of disruption in
the experience of reality, such as hallucinations and delusions,
which are grouped as positive symptoms. In addition, many patients
with schizophrenia show signs of impoverishment in thinking, emotional
experience, and social engagement, which are grouped as negative
symptoms. A wide range of other signs and symptoms are also observed in
this illness, including disorganized thoughts and behaviors, negative
mood states, and behavioral impulsivity.
