Abstract

Dementia represents a heterogeneous group of neurodegenerative syndromes characterized by progressive cognitive decline, impaired daily functioning, and behavioral changes. The most common forms include Alzheimer’s disease (AD), vascular dementia (VaD), dementia with Lewy bodies (DLB), and frontotemporal dementia (FTD), each with unique pathophysiological underpinnings. Despite differences, these disorders share converging pathways such as synaptic dysfunction, protein aggregation, and neuroinflammation. This review summarizes the major dementia subtypes, highlights their clinical and molecular features, and discusses overlapping and distinct mechanisms. Understanding both shared and divergent aspects is essential for diagnostic accuracy and therapeutic development.
