Which term describes symptoms that indicate a reduction in the ability to function in daily life?

The term that describes symptoms indicating a reduction in the ability to function in daily life is "negative symptoms." Negative symptoms refer to a decrease or loss of normal functions and behaviors, which can significantly impact a person's capacity to engage in daily activities, maintain relationships, and express emotions. These symptoms can include social withdrawal, lack of motivation, anhedonia (inability to feel pleasure), and flat affect (reduced emotional expression).

Understanding negative symptoms is essential, as they are key in assessing the functional impact of mental illnesses, particularly in conditions like schizophrenia. By recognizing these symptoms, mental health professionals can better tailor treatment plans that address the overall functioning and well-being of the individual.
