Psychomotor Retardation

Psychomotor retardation is a slowness of thought (bradyphrenia) and movement (bradykinesia) seen in psychiatric disorders, particularly depression. It may be confused with the akinesia of parkinsonism, and abulic or catatonic states. Psychomotor retardation may also be a feature of the "subcortical" type of dementia, or of impairments of arousal (obtundation).
