avolition
Pronunciation: ay-voh-LISH-un
A negative symptom characterized by severe lack of motivation and initiative to pursue goal-directed activities.
Full Definition
Avolition is one of the core negative symptoms of schizophrenia, characterized by a severe reduction in motivated, goal-directed behavior and activity. Patients with avolition demonstrate persistent lack of initiative in work, education, self-care, or social activities, which cannot be attributed to cognitive impairment, depression, or environmental factors. This symptom significantly impacts functional outcomes and quality of life, often persisting despite treatment of positive symptoms. Avolition represents a distinct clinical entity separate from apathy or depression, though differential diagnosis can be challenging in clinical practice.
Usage
Usage note: Distinguish from depression or apathy in differential diagnosis; part of negative symptom cluster.
