Cognitive impairment after stroke is very common, but the trajectory and extent of cognitive decline after stroke are not yet clear
.
Recently, the heart blood vessels published a research article on the disease areas authoritative journal Stroke, researchers aimed to assess the use of individual participant data from stroke after stroke, cognitive and cognitive Union of the process of change and determinants
Stroke, heart blood vessels
The study included 9 longitudinal hospital cohorts from 7 countries
.
The neuropsychological test scores and normative data are used to calculate the overall cognition and standardized scores for the 5 cognitive domains
The researchers included non-stroke controls to assess differences in incidence
.
According to the literature showing short-term improvement of cognitive function after stroke and the researchers' own data, the key analysis is limited to one year after stroke to focus on its long-term effects
The study included 1488 patients (mean age 66.
3 years; SD 11.
1; 98% were ischemic stroke), and the median follow-up time was 2.
68 years (25-75th percentiles were 1.
21-4.
14 years) )
.
After the initial improvement period of up to 1 year after stroke, after adjusting for age, gender, education, vascular risk factors, and stroke characteristics, overall cognition and all areas except executive function declined (-0.
It can be seen that within 1 to 3 years after the onset of stroke , cognitive decline occurs in patients with a stroke, and the rate of decline is faster than that of controls without stroke
.
The accelerated rate of decline is associated with old age and recurrent stroke
Cognitive decline occurs in stroke patients within 1 to 3 years after the onset of the disease, and the rate of decline is faster than that of controls without stroke
