Rare Dementia Can Strike Swiftly, Experts Warn
31 Oct
Summary
- Some dementias, including Lewy body dementia, can progress rapidly over weeks or months.
- Fluctuating cognition, hallucinations, and sleep disturbances are early signs of LBD.
- Co-existing conditions like Alzheimer's can accelerate dementia decline.
While often perceived as slow-progressing, certain dementias, including Lewy body dementia (LBD), can advance rapidly, sometimes over weeks or months rather than years. This rapid progression, affecting less than five percent of dementia cases, can be difficult to detect early. Initial symptoms of LBD may involve cognitive fluctuations, attention difficulties, visual hallucinations, and sleep disturbances like acting out dreams.
Lewy bodies are protein clumps in neurons, and their exact cause remains unclear. LBD shares symptoms with Parkinson's disease, such as stiffness and falls, and can also coexist with Alzheimer's disease. When LBD and Alzheimer's occur together, the decline can be significantly accelerated. Diagnosing Alzheimer's often involves cognitive evaluations and imaging, while new blood tests are improving detection.
Proper diagnosis is critical, as misdiagnosis, such as Robin Williams' case where LBD was only confirmed post-mortem, can impact care. A supportive "village approach" involving various therapies and simplified communication strategies can help individuals and families navigate LBD. It's vital to remember the person with dementia remains present, and tailored approaches can maintain connections.
