Lewy Body Dementia (Dementia with Lewy Bodies)
- Progressive dementia of the elderly
- Second MCC of degenerative dementia after Alzheimers
- Motor features of Parkinsons
- Visual hallucinations
- Variation in alertness and attention
- Sleep disorder
- Orthostatic hypotension leading to syncope and repeated falls.
- Round, eosinophilic, intracytoplasmic neuronal inclusions
- Composed of alpha- synuclein and ubiquitin
- Loss of dopinergic neurons (like Parkinsons)
- Loss of ACH-producing neurons (Like Alzehimers)
- Presence of amyloid plaques (Like Alzehimers)
Notice that Lewy body dementia has a lot of crossover with Parkinsons and Alzheimers which can lead to a misdiagnosis.
