ABSTRACT
Objective To explore the clinical characteristics of cognitive impairment in different age groups with the same severity of white matter lesions.Methods This study involved 110 consecutively recruited patients with white matter lesions(WMLs)from the Department of Neurology at Beijing Tiantan Hospital from August 2014 to March 2017.Patients were aged from 50 to 85 with a mean age of 63.1±9.7,and they were divided into an elderly group with a mean age of 71.6±5.2 (range65-85 years)and a middle aged group with a mean age of 54.8 ± 3.4 (range50-60 years).The severity of white matter lesions was evaluated with the Fazekas scale.MoCA was used to evaluate the cognitive function of patients.Results For Fazekas 1,the MoCA score was 25.5 ± 2.2 in the elderly group and 28.1 ± 1.4 in the middle aged group(t =6.946,P =0.000);the score for visuospatial and execution abilities was 3.8 ± 0.9 in the elderly group and 4.5 ± 0.6 in the middle aged group(t =3.7 2 6,P =0.0 2 3);the score for delayed memory was 2.7 ± 1.5 in the elderly group and 4.0 ± 1.0 in the middle aged group(t =4.365,P =0.018).For Fazekas 2,the MoCA score was 22.5±2.5 in the elderly group and 24.1 ± 1.5 in the middle aged group(t =3.361,P =0.034);the score for visuospatial and execution abilities was 2.8 ± 1.2 in the elderly group and 3.8 ± 0.8 in the middle aged group(t=6.473,P=0.007);the score for concentration was 4.6± 1.3 in the elderly group and 5.6±0.5 in the middle aged group(t=0.491,P=0.721).For Fazekas 3the MoCA score was 15.2 ± 3.4 in the elderly group and 19.4 ± 2.8 in the middle aged group(t =4.709,P =0.001);the score for visuospatial and execution abilities was 1.8 ± 1.1 in the elderly group and 2.8± 1.4 in the middle aged group(t =1.563,P =0.043);the score for concentration was 3.3± 1.1 in the elderly group and 4.4± 1.4 in the middle aged group(t=2.231,P=0.026);the score for orientation was 4.2 ± 1.3 in the elderly group and 5.7 ± 0.5 in the middle aged group (t=3.255,P =0.000).Conclusions WMLs can increase the risk of vascular cognitive impairment and cause decline in multiple cognitive functions in both middle aged and elderly people.Cognitive dysfunction in age-related WMLs is mainly characterized by impairment in visuospatial and execution abilities.
