Aboulia or Abulia (from the Greek "αβουλία", meaning "un-will"), in neurology, refers to a lack of will or initiative and is one of the Disorders of Diminished Motivation or DDM. Aboulia falls in the middle of the spectrum of diminished motivation, with apathy being less extreme and akinetic mutism being more extreme than aboulia. A patient with aboulia is unable to act or make decisions independently. It may range in severity from subtle to overwhelming. It is also known as Blocq's disease (which also refers to abasia and astasia-abasia). Abulia was originally considered to be a disorder of the will.
