Understanding Lewy Body Dementia: A Lesser-Known Form of Dementia Linked to Parkinsonism

In the UK, over 944,000 people are living with dementia, but not all forms of this condition are equally understood. Dr. Kellyn Lee, CEO of The Dementia Care Hub, has shed light on Lewy Body Dementia (LBD), a lesser-discussed form of the condition that affects 10 to 15 out of every 100 dementia patients, making it the third most common type after Alzheimer's and vascular dementia. LBD is caused by abnormal protein clumps called Lewy bodies in the brain, leading to symptoms such as memory difficulties, challenges in performing daily tasks, mood changes, and alertness issues. A key symptom is 'vagueness,' which can manifest as fluctuating consciousness. Patients may also experience severe communication challenges, visual hallucinations, and a condition known as 'spontaneous Parkinsonism,' characterized by slow movement, stiffness, tremors, and shuffling gait, similar to Parkinson's disease. These symptoms can increase the risk of falls and make everyday activities like DIY projects challenging. Unlike other forms of dementia, LBD may present with gradual memory loss and early-onset issues with visual perception and alertness. While there is no cure for LBD, treatments such as medications, cognitive stimulation therapies, and rehabilitation can help manage symptoms. Dr. Lee emphasizes the importance of consulting a GP if symptoms arise. Common symptoms of Lewy Body Dementia include visual perception challenges, language difficulties, hallucinations, fainting, swallowing problems, depression, anxiety, slow movement, and disturbed sleep patterns. Alertness levels can fluctuate unexpectedly, and significant memory loss may not appear until later stages.
