Psychomotor retardation is also referred to as psychomotor slowing and is a collection of symptoms that are present in depression and in other mental disorders such as schizophrenia, reports MedScape. It is difficult to tell psychomotor retardation from reduced processing speed at this time, but scientists are working on identifying the clinical features of psychomotor retardation that differ from reduced processing speed, as of 2015.
Psychomotor retardation involves a person experiencing motor and cognitive trouble. This can be seen in a person's speech and in the way that they move their body. There is a scale for those with this depression, called the Salpetriere Retardation Rating Scale, which looks at the severity of the retardation. Patients who score in the higher ranges of the test are often prescribed antidepressant medication to help with the severity of symptoms, according to the BioMed Research Journal found on the Hindawi Publishing Corporation's website.
One of the ways that depression is diagnosed is by looking for psychomotor symptoms, according to WebMD. Some of these psychomotor symptoms may include the inability to eat, difficulty in taking care of hygiene matters and an inability to perform physical tasks, even if they are as simple as getting out of bed in the morning. Depression affects a person's ability to work, socialize and can even affect their personality.
