What You Need To Know About Lewy Body Dementia

Diagnosis

A Lewy body dementia diagnosis requires a decline in the patient’s ability to think and two of the following: Parkinson’s disease symptoms, progressive visual hallucinations, or impaired cognitive function or fluctuating alertness. Other characteristics of Lewy body dementia that are used to make a diagnosis include REM sleep behaviour disorder and autonomic dysfunction. No single test is used to diagnosis the disease. Instead, a doctor may use tests to rule out other conditions.
