[Vascular dementia]

Area of Science:

• Neurology
• Neuroscience
• Pathology

Background:

• Vascular dementia encompasses diverse clinical and neuropathological presentations of cerebrovascular disease leading to dementia.
• It is a prevalent condition, yet significant knowledge gaps persist regarding its underlying mechanisms and progression.
• Existing research highlights the heterogeneity of vascular dementia, complicating diagnosis and treatment.

Purpose of the Study:

• To propose an overarching disease concept for vascular dementia that integrates pre-dementia stages.
• To address the clinical and neuropathological heterogeneity inherent in vascular dementia.
• To guide future research toward identifying specific subtypes for targeted therapeutic development.

Main Methods:

• Review and synthesis of current literature on vascular dementia.
• Analysis of proposed diagnostic and conceptual criteria for vascular dementia.
• Discussion of neuropathological findings and clinical presentations.

Main Results:

• Vascular dementia presents a complex spectrum of cerebrovascular disease-related cognitive impairment.
• A unified disease concept is proposed to encompass the heterogeneity and pre-dementia phases.
• The need for subtype identification based on distinct pathophysiological mechanisms is emphasized.

Conclusions:

• Vascular dementia is a complex, heterogeneous condition requiring a refined conceptual framework.
• Further research is crucial for delineating specific vascular dementia subtypes.
• Identifying distinct pathophysiological mechanisms is key to advancing treatment strategies for vascular dementia.
