Psychomotor retardation

Psychomotor impairment involves a slowing down of thought and a reduction of physical movements in an individual. Psychomotor impairment can cause a visible slowing of physical and emotional reactions, including speech and affect.[1]

Psychomotor impairment is most commonly seen in people with major depression and in the depressed phase of bipolar disorder;[2] it is also associated with the adverse effects of certain drugs, such as benzodiazepines.[3] Particularly in an inpatient setting, psychomotor impairment may require increased nursing care to ensure adequate food and fluid intake and sufficient personal care. Informed consent for treatment is more difficult to achieve in the presence of this condition.[citation needed]



Examples of psychomotor impairment include the following:[citation needed]

  • Unaccountable difficulty in carrying out what are usually considered "automatic" or "mundane" self care tasks for healthy people (i.e., without depressive illness) such as taking a shower, dressing, self grooming, cooking, brushing one's teeth and exercising.
  • Physical difficulty performing activities which normally would require little thought or effort such as walking up a flight of stairs, getting out of bed, preparing meals and clearing dishes from the table, household chores or returning phone calls.
  • Tasks requiring mobility suddenly (or gradually) may inexplicably seem to be "impossible." Activities such as shopping, getting groceries, caring for your daily needs and meeting the demands of employment or school are commonly affected.
  • Activities usually requiring little mental effort can become challenging. Balancing one's checkbook, making a shopping list or making decisions about mundane tasks (such as deciding what errands need to be done) are often difficult.

In schizophrenia, activity level may vary from psychomotor retardation to agitation; the patient will experience periods of listlessness and may be unresponsive, and at the next moment be active and energetic.[5]
