Psychomotor retardation

• Psychiatric disorders – schizophrenia, severe depression, bipolar disorder, eating disorders, anxiety disorders, etc.
• Psychiatric medicines (if taken as prescribed or improperly, overdosed, or mixed with alcohol)
• Parkinson's disease[4]
• Genetic disorders - Wiedemann–Steiner syndrome, Say–Meyer syndrome, Qazi–Markouizos syndrome, Tranebjaerg-Svejgaard syndrome, etc.

Examples of psychomotor retardation include the following:

• 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]
