Psychomotor retardation ..(also known as "psychomotor impairment" or "motormental retardation") involves a slowing-down of thought and a reduction of physical movements in an individual. Psychomotor retardation can cause a visible slowing of physical and emotional reactions, including speech and affect. This is most-commonly seen in people with major depression and in the depressed phase of bipolar disorder; it is also associated with the adverse effects of certain drugs, such as benzodiazepines, cannabis and antipsychotics. 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.
