Updates on vascular dementia

Area of Science:

• Neurology
• Gerontology
• Cardiovascular Medicine

Background:

• Vascular dementia (VaD) is the second most common dementia type, following Alzheimer's disease (AD).
• Improvements in managing cardiovascular risk factors have led to a decreased incidence of VaD compared to AD.
• While vascular pathologies causing brain hypoperfusion and hypoxia are primary suspected mechanisms, neuroinflammation may also play a role.

Purpose of the Study:

• To review current knowledge on VaD epidemiology, risk factors, and disease mechanisms.
• To highlight the significance of lifestyle modifications and comorbidity management in VaD prevention and progression.
• To summarize existing treatments and emerging therapeutic strategies for VaD.

Main Methods:

• Narrative review of existing literature on vascular dementia.
• Analysis of epidemiological data and risk factors.
• Examination of current and investigational therapeutic approaches.

Main Results:

• VaD incidence is decreasing due to improved cardiovascular health management.
• Clinical presentation of VaD often overlaps with AD, posing diagnostic challenges.
• Biomarkers are being developed to aid in differentiating VaD from other dementias.
• Current treatments for VaD are largely symptomatic, lacking disease-modifying agents.

Conclusions:

• Optimizing lifestyle and managing comorbid conditions are crucial for preventing or slowing VaD.
• Novel therapies, including stem-cell therapy and neuromodulation, are under investigation.
• Further research is needed to develop effective treatments that target the underlying mechanisms of VaD.
