Lewy body dementias LBD affect an estimated 1. At the Lewy Body Dementia Association LBDA, we understand that though many families are affected by this disease, few individuals and medical professionals are aware of the symptoms, diagnostic criteria, or even that LBD exists. There are important facts about Lewy body dementias that you should know if you, a loved one, or a patient you are treating may have LBD. Lewy body dementias LBD are the second most common form of degenerative dementia. LBD is an umbrella term for dementia associated with the presence of Lewy bodies abnormal deposits of a protein called alpha-synuclein in the brain. LBD can have three common presentations: Regardless of the initial symptom, over time all three presentations of LBD will develop very similar cognitive, physical, sleep and behavioral features. The most common symptoms of LBD include: Impaired thinking, such as loss of executive function planning, processing information, memory, or the ability to understand visual information. A variety of drugs, including anticholinergics and some antiparkinsonian medications, can worsen LBD symptoms.

Under normal conditions, dopamine sends messages to the part of the brain that controls movement and coordination. As PD progresses, dopamine production decreases, affecting movement and coordination. A hallmark of PD, Lewy bodies are the clumping of the protein alpha-synuclein in the substantia nigra. Loss of cells in other areas of the brain, including the brain stem and the olfactory bulb, also may play a role in PD. Though symptoms vary from person to person, they often include stiffness, slowness, impaired balance, and tremor of the hands, arms, legs, jaw, and face. What Causes PD? Despite years of research, the exact causes are unknown. However, it has been suggested that the disease is caused by some combination of genetic predisposition and environmental factors, such as exposure to certain pesticides and heavy metals.
