Lewy Body Dementia

Lewy Body Dementia is a brain disorder that affects the nervous system and leads to problems with thinking, movement, and behavior. It is caused by abnormal clumps of protein called Lewy bodies that build up inside brain cells. These clumps interfere with normal brain function, causing symptoms like memory loss, difficulty with attention, and changes in alertness. People with this condition may also experience hallucinations and problems with movement similar to Parkinson’s disease. The disease progressively worsens over time, impacting daily activities and quality of life.

Lewy Body Dementia (LBD) is a progressive neurodegenerative disorder characterized by the accumulation of alpha-synuclein protein aggregates known as Lewy bodies within cortical and subcortical neurons. It is a major cause of dementia in the elderly, distinct from but overlapping with Parkinson’s disease dementia. The pathophysiology involves widespread neuronal loss and synaptic dysfunction, particularly affecting the dopaminergic and cholinergic systems. Clinically, LBD presents with fluctuating cognition, recurrent visual hallucinations, and parkinsonism. Autonomic dysfunction and REM sleep behavior disorder are common non-cognitive features. The disease is significant due to its rapid progression and sensitivity to neuroleptic medications.
