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)
