Lewy body dementia, also known as LBD, is the second most common type of dementia after Alzheimer's disease. Protein deposits called Lewy bodies develop in nerve cells in the brain. The protein deposits affect brain regions involved in thinking, memory and movement.

Understanding the Context

Lewy body dementia (LBD) is a progressive brain disorder that happens when certain proteins called Lewy bodies build up in your brain cells. This makes it harder to think clearly and do everyday activities. LBD is the second most common form of neurodegenerative dementia, after Alzheimer’s disease. LBD is an umbrella term for a type of dementia associated with the presence of Lewy bodies (abnormal deposits of a protein called alpha-synuclein) in the brain.

Key Insights

Lewy body dementia (LBD) stages are similar to those seen in other dementias, but this condition is known to have unique progression patterns that can make disease predictability challenging. On this page, you can learn about LBD, including common symptoms and how it is diagnosed. LBD is a disease associated with abnormal deposits of a protein called alpha-synuclein in the brain. These deposits, called Lewy bodies, affect chemicals in the brain. Lewy body dementia (LBD) is an umbrella term for two similar and common subtypes of dementia: [1] dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD).

Final Thoughts

[2][3][4][5] Both are characterized by changes in thinking, movement, behavior, and mood. [1] Through comprehensive resources and personal insights from others who have experienced LBD first-hand, you’ll find the understanding you need to cope with this disease, along with the love, support and know-how to help you and your family through the twists and turns that may lay ahead. Lewy body dementia (LBD) is a brain disorder that can lead to problems with thinking, movement, behavior, and mood. Visual hallucinations, or seeing things that are not there, are a common symptom, and tend to happen early on.
