Avolition

Avolition is a symptom classified among the so-called negative symptoms of schizophrenia, alongside related symptoms such as anhedonia and emotional blunting, both already documented elsewhere in this section, consisting of a marked reduction or near-absence of the motivation and inner drive needed to begin and follow through on purposeful, goal-directed activities, including basic self-care and hygiene, work or study, and social engagement. Clinicians distinguish avolition carefully from simple laziness or a voluntary lack of effort, since the underlying difficulty is understood as an impairment in the person's actual motivational capacity rather than a conscious choice to withhold effort that the person could otherwise exert. Avolition and the other negative symptoms of schizophrenia are recognized as being among the most functionally disabling and among the most difficult to treat aspects of the illness, since research has repeatedly found that negative symptoms respond far less consistently to standard antipsychotic medication than the positive symptoms of schizophrenia, such as hallucinations and delusions, which these medications were originally developed primarily to address. Beyond schizophrenia, avolition-like reductions in motivation and initiative are also observed in a number of other psychiatric and neurological conditions that involve disruption to the brain's frontal-subcortical circuits, which are understood to play a central role in generating and sustaining goal-directed motivation more generally.
