Predictors for vascular cognitive impairment in stroke patients

Area of Science:

• Neurology
• Neuroscience
• Public Health

Background:

• Vascular cognitive impairment (VCI) affects approximately two-thirds of stroke patients.
• A previous study validated the NINDS-CSN harmonization standard for VCI diagnosis in the Chinese population.
• This study investigated predictors of VCI in Chinese patients following a stroke.

Purpose of the Study:

• To identify key predictors for vascular cognitive impairment (VCI) in Chinese stroke patients.
• To analyze epidemiological, clinical, and neuroimaging factors associated with VCI.
• To provide insights for VCI prevention and management strategies in this demographic.

Main Methods:

• Compared epidemiological, clinical, and neuroimaging data between stroke patients with and without VCI.
• Utilized univariate and logistic regression analyses to determine significant VCI predictors.
• Assessed infarcts, lacunes, white matter hyperintensities, and brain atrophy.

Main Results:

• 56 stroke patients (55.4% diagnosed with VCI) were analyzed.
• VCI was associated with older age, lower education, female sex, recurrent stroke, higher apathy, and worse pre-stroke cognition.
• Independent predictors included lower educational level, female sex, recurrent stroke, and global cortical atrophy.

Conclusions:

• Lower education, female sex, recurrent stroke, and global cortical atrophy are independently associated with VCI in Chinese stroke patients.
• These findings highlight specific risk factors for VCI in this population.
• Understanding these predictors can aid in targeted interventions and improved patient outcomes.
