Psychomotor retardation involves a slowing down of thought and a reduction of physical movements in an individual. It can cause a visible slowing of physical and emotional reactions, including speech and affect.Tryon, W.W., 1991. Activity Measurement in Psychology and Medicine.

Psychomotor retardation is most commonly seen in people with major depression and in the depressed phase of bipolar disorder;{{cite journal| vauthors=Buyukdura JS, McClintock SM, Croarkin PE| title=Psychomotor retardation in depression: biological underpinnings, measurement, and treatment | journal=Prog Neuropsychopharmacol Biol Psychiatry | year= 2011 | volume= 35 | issue= 2 | pages= 395–409 | pmid=21044654 | doi=10.1016/j.pnpbp.2010.10.019 | pmc=3646325 }} it is also associated with the adverse effects of certain drugs, such as benzodiazepines.{{Cite journal |last1=Allgulander |first1=C. |last2=Bandelow |first2=B. |last3=Hollander |first3=E. |last4= Montgomery |first4=SA. |last5=Nutt |first5=DJ. |last6=Okasha |first6=A. |last7=Pollack |first7=MH. |last8=Stein |first8=DJ. |last9=Swinson |first9=RP. |last10=World Council Of |first10=Anxiety |title=WCA recommendations for the long-term treatment of generalized anxiety disorder |journal=CNS Spectr |volume=8 |issue=8 Suppl 1 |pages=53–61 |date=Aug 2003 |pmid=14767398|display-authors=8 |doi=10.1017/S1092852900006945|s2cid=32761147 }} Particularly in an inpatient setting, psychomotor retardation 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|date=December 2018}}

Examples

Examples of psychomotor retardation include the following:{{cite book |url=https://www.mendeley.com/catalogue/69489f0e-421c-3be2-8918-ae0dc2b5d9ef |author=Benson, D.

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, grooming, cooking, brushing teeth, and exercising.
Physical difficulty performing activities that normally require little thought or effort, such as walking up stairs, getting out of bed, preparing meals, and clearing dishes from the table, household chores, and returning phone calls.
Tasks requiring mobility suddenly (or gradually) may inexplicably seem "impossible". Activities such as shopping, getting groceries, taking care of daily needs, and meeting the demands of employment or school are commonly affected.
Activities usually requiring little mental effort can become challenging. Balancing a checkbook, making a shopping list, and 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 experiences periods of listlessness and may be unresponsive, and at the next moment be active and energetic.{{cite book |first=Christopher D. |last=Frith |authorlink=Chris Frith |title=The cognitive neuropsychology of schizophrenia |chapter=HOW DO THE BEHAVIOURAL ABNORMALITIES OF SCHIZOPHRENIA RELATE TO THE BRAIN? |quote="Psychomotor retardation" is a phenomenon, often observed in neurological patients, which has much in common with the negative features of schizophrenia.
