Schizophrenia is a condition that hinders the ability of a person to think, feel, and act. Although the exact cause of schizophrenia is unknown, altered brain structure and chemistry, genetics, and environmental factors all may play a role. In Schizophrenia, a decrease or absence of normal motivational and interest-related behaviors or expressions are referred to as negative symptoms. They are also identified as characteristics deficient in a person. These comprise loss of directedness or motivation, evolution, withdrawal from social life, alogia, and blunted effect. On the other hand, positive symptoms indicate abnormal or excessive activity. They can also be bizarre additions to the behavior of an individual. For instance, disordered speech, disorganized behaviorand thinking, hallucinations, heightened perceptions, delusions, and inappropriate affect.
Negative symptoms in Schizophrenia entail a ‘minus’ or ‘reduction’ in behavior. For example, anhedonia, social withdrawal, loss of interest in other things rather than themselves, and being flat and emotionless. Once a person is diagnosed with Schizophrenia, they tend to depict difficulties in following schedules and are unhappy. Contrastingly, positive symptoms pertain to changes in behavior or thoughts. It is an ‘addition’ that yields negative effects like delusions (persecutory, eretomanic, and referential) and hallucinations (visual, tactile, gustatory and olfactory).
