Impulsivity can be conceptualised as a predisposition
towards rapid, unplanned actions without regard to consequences
[20]. As impulsive behaviour is one of the diagnostic
criteria for mania [1] the concept of impulsivity is particularly
relevant to bipolar disorder (BD). It is unclear, however,
whether increased impulsivity occurs in depression as well and
whether it persists as a trait characteristic during periods of
remission.
