[12] [13] The Lewy body dementias—dementia with Lewy bodies (DLB), and Parkinson's disease dementia (PDD)—are distinguished by the timing when cognitive and motor symptoms appear. [14] The two Lewy body dementias are often considered to belong on a spectrum of Lewy body disease that includes Parkinson's disease. [2] [5]
Dementia with Lewy bodies; Other names: Diffuse Lewy body disease, dementia due to Lewy body disease: Microscopic image of a Lewy body (adjacent to arrowhead) in a neuron of the substantia nigra; scale bar=20 microns (0.02 mm)
In histopathology, cortical Lewy bodies are a distinguishing feature for dementia with Lewy bodies, but may occasionally be seen in ballooned neurons characteristic of behavioural variant frontotemporal dementia and corticobasal degeneration, [18] as well as in patients with other tauopathies. [19]
Lewy body dementia, which is the condition actor Robin Williams was diagnosed with before his death, is linked with abnormal deposits of protein in the brain known as Lewy bodies, the NIA explains.
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]
In comparison, 1,286 participants taking tamsulosin developed dementia with Lewy bodies for a rate of 10.76 cases per 10,000 people per year, and 193 participants in the 5ARIs group developed ...

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.
