Negative symptoms refer to a reduction or absence of normal emotional and behavioral functions. They can include a lack of motivation, diminished emotional expression, and social withdrawal. Individuals may struggle to experience pleasure in everyday activities, leading to a decrease in overall quality of life. These symptoms are often associated with mental health conditions such as schizophrenia and can significantly impact a person's ability to engage in social interactions and maintain relationships. Unlike positive symptoms, which involve the presence of abnormal behaviors, negative symptoms reflect a deficit in typical emotional responses and actions.
