Lewy body dementia. 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). [2][3][4][5] Both are characterized by changes in thinking, movement, behavior, and mood. [1] The two conditions have similar features and may have similar ...

Lewy bodies may be found in the midbrain (within the substantia nigra) or within the cortex. A classical Lewy body is an eosinophilic cytoplasmic inclusion consisting of a dense core surrounded by a halo of 10 nm wide radiating fibrils, the primary structural component of which is alpha-synuclein (α-synuclein).

The Dementia with Lewy Bodies Consortium (DLB Consortium or DLBC) is an international multidisciplinary collaboration of researchers interested in the dementia with Lewy bodies. [1] It first convened in Newcastle upon Tyne, England, in October 1995. [1] Between 1995 and 2005, it issued three DLBC Consensus Reports on dementia with Lewy bodies.
Parkinson's disease dementia (PDD) is dementia that is associated with Parkinson's disease (PD). [1] Together with dementia with Lewy bodies (DLB), it is one of the Lewy body dementias characterized by abnormal deposits of Lewy bodies in the brain. [2][3][4][5] Parkinson's disease starts as a movement disorder, but progresses in most cases to ...
Dementia with Lewy bodies. In medicine, the cingulate island sign is a finding on FDG-PET brain scans that metabolism in the posterior cingulate cortex is preserved. It can help to identify dementia with Lewy bodies (DLB) and distinguish it from Alzheimer's disease and other dementias. [1][2]
