Aboulia or Abulia (from the Greek "αβουλία", meaning "non-will"), in
neurology, refers to a lack of will or initiative. The patient is unable to act or make decisions independently. It may range in severity from subtle to overwhelming. Abulia may result from a variety of brain injuries which cause personality change, such as dementing illnesses, trauma, or
intracerebral hemorrhage (stroke), especially stroke causing diffuse injury to the right hemisphere. Abulia has also been associated with
amphetamine widthdrawal.It may complicate rehabilitation when a stroke patient is uninterested in performing tasks like walking despite being capable of doing so. It should be differentiated from
apraxia, when a brain injured patient has impairment in comprehending the movements necessary to perform a motor task despite not having any paralysis that prevents performing the task; that condition can also result in lack of initiation of activity.
