Dementia with Lewy Bodies – Overview
Dementia with Lewy bodies is a progressive neurodegenerative disorder that combines symptoms of both dementia and Parkinson’s disease. It is the second most common form of degenerative dementia in older adults, after Alzheimer’s disease. This disease is characterised by abnormal protein deposits—known as Lewy bodies—accumulating in the brain, particularly in areas that regulate thinking, movement, behaviour, and mood.
These protein deposits interfere with normal brain cell function, causing a decline in mental abilities. What makes this distinct from other forms of dementia is its combination of cognitive decline, visual hallucinations, fluctuating alertness, and motor symptoms such as stiffness or tremors. These features often overlap with those of Alzheimer’s disease and Parkinson’s disease, which can complicate diagnosis.
People affected by this condition typically experience changes in their ability to think clearly, visualise space, and regulate bodily movements. Symptoms tend to progress gradually but may vary in intensity from day to day. It is common for individuals to experience vivid dreams, disrupted sleep, mood disturbances, and sensitivity to certain medications, particularly antipsychotics.
Dementia with Lewy Bodies
Although this condition has no known cure, a combination of treatments, therapies, and support strategies can significantly enhance quality of life. Early recognition and management of symptoms are essential in providing appropriate care and improving outcomes for both individuals and their families.
In summary, dementia with Lewy bodies is a complex and multifaceted condition that blends features of dementia and movement disorders. Awareness, timely diagnosis, and compassionate care are key in helping those affected live as fully and independently as possible.
