This course is designed for all medical professionals who come in contact with persons who have been diagnosed with a form of dementia and may have difficult behavior. These patients may be seen at home with a caregiver, in doctors' offices, hospitals, mental health settings, long-term care communities, or other settings.


Friedrich Heinrich Lewy
Friedrich Heinrich Lewy

Dr. Lewy was a prominent German-born American neurologist. In 1912, Friedrich Heinrich Lewy first described these inclusion bodies named after him. He is best known for the discovery of the protein masses in brain biopsy samples, which are a characteristic indicator of Parkinson's disease and dementia with Lewy bodies.

The second most common form of dementia is Lewy Body. It is also called Lewy Body Dementia (LBD), Diffuse Lewy Body Disease, Lewy Body Disease, Senile Dementia of Lewy Type, Cortical Lewy Body Disease, Lewy Body Variant of Alzheimer's Disease or Parkinson's Disease Dementia. It is currently widely underdiagnosed and yet affects an estimated 1.3 million people (considerably more men than women) just in the United States. LBD usually occurs sporadically, in people with no known family history of the disease. About 20% of persons with a dementia have Lewy Body Dementia. This is a progressive degenerative disease of the brain. It shares characteristics and clinically recognizable features with several other diseases, especially Alzheimer's and Parkinson's.

There are two types of LBD:

The earliest signs of these two diseases differ but reflect the same biological changes in the brain. Over time, people with dementia with Lewy bodies or Parkinson's disease dementia may develop similar symptoms. LBD patients will benefit from regularly scheduled visits with a neurologist who specializes in dementia and/or movement disorders. Memory disorder and movement disorder clinics are found all over the world. They are usually associated with a medical university or large hospital systems.
