Reference from A.D.A.M. Neurological deficits - focal. A focal neurologic problem can affect any of these functions: Movement changes including paralysis, weakness, loss of muscle control, increased muscle tone, loss of muscle tone, or movements a person cannot control (involuntary movements, such as tremor)
One or more symptoms or deficits affecting voluntary motor or sensory function that suggest a neurological or other general medical condition. Psychological factors are judged to be associated with the symptom or deficit because the initiation or exacerbation of the symptom or deficit is preceded by conflicts or other stressors. The symptom or deficit is not intentionally produced or feigned (as in Factitious Disorder or Malingering). The symptom or deficit cannot, after appropriate investigation, be fully explained by a general medical condition, or by the direct effects of a substance, or as a culturally sanctioned behavior or experience.
