Vascular Cognitive Impairment and Dementia.

Area of Science:

• Neurology
• Geriatrics
• Public Health

Background:

• Vascular cognitive impairment and dementia (VCID) is a significant cause of cognitive decline, distinct from degenerative dementias.
• Understanding the diverse pathophysiology of VCID, including various cerebrovascular diseases, is essential for effective management.
• VCID represents the leading nondegenerative cause of dementia, highlighting the importance of preventative strategies.

Purpose of the Study:

• To provide a comprehensive overview of vascular cognitive impairment and dementia (VCID).
• To discuss epidemiology, pathophysiology, clinical approaches, and management strategies for VCID.
• To emphasize the role of understanding cerebrovascular diseases and managing risk factors in VCID.

Main Methods:

• Review of current literature on vascular cognitive impairment and dementia.
• Analysis of diagnostic criteria and phenotypic categories for vascular dementia.
• Examination of risk factor management and therapeutic interventions for VCID.

Main Results:

• VCID pathophysiology is heterogeneous, with diagnostic criteria categorizing it into four main phenotypes.
• Control of cardiovascular risk factors (blood pressure, cholesterol, blood sugar) is key for VCID prevention.
• Cerebral amyloid angiopathy requires specific risk factor management due to hemorrhage risk.
• Cognitive rehabilitation shows promise in improving global cognitive function in VCID patients.

Conclusions:

• Diagnosis relies on thorough clinical evaluation and neuroimaging.
• Optimizing management of identified risk factors is paramount for preventing and managing VCID.
• Symptomatic management and secondary prevention are crucial after vascular brain injury.
