Understanding the Impact of Arteriolosclerosis CSVD on Cognitive Function and MRI Burden

Published on July 14, 2023

Just as a clogged drain can affect the flow of water in your pipes, arteriolosclerosis cerebral small vessel disease (CSVD) can have a profound impact on cognitive function and the total burden seen on an MRI scan of the brain. In this study, researchers collected data from 146 patients with arteriolosclerosis CSVD to identify factors associated with cognitive function and total MRI burden. They found that deep cerebral atrophy was linked to cognitive dysfunction in CSVD, while hypertension played a role in the overall MRI burden. These findings suggest that managing hypertension and monitoring cerebral atrophy may be important for preventing cognitive decline in individuals with arteriolosclerosis CSVD. Moving forward, additional research is needed to further explore the mechanisms behind these associations and develop targeted interventions to improve outcomes for patients affected by this condition.

ObjectiveArteriolosclerosis cerebral small vessel disease (CSVD) is a common type of CSVD. This study aimed to explore the factors associated with cognitive function and total MRI burden related to the disease.MethodsThe demographic characteristics, clinical manifestations, cognitive function score, Barthel Index (BI), blood test index, and follow-up results of arteriolosclerosis CSVD patients treated for the first time in our hospital from January 2014 to August 2022 were collected. White matter hyperintensity (WMH) Fazekas score, total MRI burden, and cerebral atrophy grade were evaluated according to brain MRI findings. Factors associated with CSVD cognitive function were analyzed by binary logistic regression. The correlative factors related to the total MRI burden of CSVD were analyzed by ordered multiple logistic regression.ResultsA total of 146 patients were included in this study, of which 132 cases (90.4%) had hypertension. There were 108 patients (74.0%) with cognitive dysfunction, 97 patients (66.4%) with balance and gait disorders, and 83 patients (56.8%) with moderate-to-severe dependence in daily life (BI ≤ 60 points). Of 146 patients, 79 (54.1%) completed clinical and imaging follow-ups for a median of 3 years. The number of patients with cognitive impairment and BI ≤ 60 points after follow-up significantly increased compared with the first admission (P < 0.001). There were also significant differences in total MRI burden (P = 0.001), WMH Fazekas score, and cerebral atrophy grade (P < 0.001). Mean age (P = 0.012), median deep WMH Fazekas score (P = 0.028), and median deep (P < 0.001) and superficial (P =0.002) cerebral atrophy grade of patients with cognitive impairment at first admission were all higher than those with non-cognitive impairment. Multivariate analysis showed that deep cerebral atrophy was independently and significantly associated with cognitive impairment of CSVD (P = 0.024), and hypertension was significantly and independently associated with total MRI burden (P = 0.001).ConclusionThe disease course of arteriolosclerosis CSVD may be related to cognitive function and total MRI burden. Deep cerebral atrophy was an independent risk factor for cognitive dysfunction in arteriolosclerosis CSVD, and hypertension was an independent risk factor for total MRI burden.
