Motor dysfunction

What are motor disorders?

Movement disorders have been reported in people with bipolar disorder, with tardive dyskinesia among the most commonly reported. This disorder is a ‘hyper-kinetic’ (excessive movement) disorder, characterised by jerky, involuntary movements, usually of the face and/or limbs. Parkinsonism is another movement disorder, which is a ‘hypo-kinetic’ (reduced movement) disorder, characterised by slowness of movement and rigidity. Movement disorders are primarily associated with the use of antipsychotics, however they have also been reported in people who are antipsychotic-naïve.

What is the evidence for movement disorders?

Low quality evidence is unclear of the prevalence of movement disorders in people with bipolar disorder.
