There is no known effective treatment. Treatment is supportive and based on the control of symptoms. In some cases, rehabilitation is needed for weakness or clumsiness. This can include physical, occupational, or speech therapy.
Occasionally, some patients are good candidates for medications that can help improve memory.
The disorder is generally progressive. It cannot be definitively diagnosed in most cases until after death.
Go to the emergency room or call the local emergency number (such as 911) if there is any sudden loss of movement, sensation, vision, speech or other impairments that may indicate a loss of neurologic functions.
