Avolition


Avolition, as a symptom of various forms of psychopathology, is the decrease in the motivation to initiate and perform self-directed purposeful activities. Such activities that appear to be neglected usually include routine activities, including hobbies, going to work and/or school, and most notably, engaging in social activities. A person experiencing avolition may stay at home for long periods of time, rather than seeking out work or peer relations.

The literal meaning of avolition is "poverty of will" and is a disabling restriction in the initiation of activity, including (but not limited to), goal-directed behaviour. People with avolition often want to complete certain tasks but lack the ability to initiate behaviours necessary to complete them. Avolition is most commonly seen as a symptom of some other disorder, but might be considered a primary clinical disturbance of itself (or as a coexisting second disorder) related to disorders of diminished motivation. In 2006, avolition was identified as a negative symptom of schizophrenia by the National Institute of Mental Health (NIMH), and have been observed in patients with bipolar disorder as well as resulting from trauma.

Avolition is sometimes mistaken for other, similar symptoms also affecting motivation, such as aboulia, anhedonia and asociality, or strong general disinterest. For example, aboulia is also a restriction in motivation and initiation, but characterized by an inability to set goals or make decisions and considered a disorder of diminished motivation. In order to provide effective treatment, the underlying cause of avolition (if any) has to be identified and it is important to properly differentiate it from other symptoms, even though they might reflect similar aspects of mental illness.

Implications from avolition often result in social deficits. Not being able to initiate and perform purposeful activities can have many implications for a person with avolition. By disrupting interactions with both familiar and unfamiliar people, it jeopardizes the patient's social relations. When part of a severe mental illness, avolition have been reported, in first person accounts, to lead to physical and mental inability to both initiate and maintain relationships, as well as work, eat, drink or even sleep.
