Abstract

Dementia presents a significant public health challenge, with Alzheimer’s disease accounting for a substantial portion of cases. This paper explores the prevalence and impact of Alzheimer’s disease, constituting 50% to 70% of dementia cases. It also delves into other common types such as vascular dementia (25%), Lewy body dementia (15%), and frontotemporal dementia. Additionally, the paper touches upon less common forms like post-traumatic dementia, Parkinson’s disease-related dementia, alpha-synuclein-associated dementia, Huntington’s disease, normal pressure hydrocephalus, Creutzfeldt–Jakob disease, and dementia in Down syndrome. Understanding the spectrum of dementia is crucial for effective management and care strategies.
