Stroke: How does long-term cognitive function change after a stroke

In the past 20 years, the death rate from stroke has declined, but the increasing ageing of the population may lead to an increase in the incidence of stroke, thereby increasing the burden of stroke

Post-stroke cognitive impairment is very common.

A recent systematic review described mixed results from longitudinal studies, which may be due to differences in cognitive testing, follow-up periods, study design, and/or patient characteristics

3) Risk factors for cognitive impairment shortly after stroke, such as diabetes , are also related to long-term cognitive decline after stroke

They were included in 9 hospital-based longitudinal cohorts from 7 countries

A total of 1488 patients (mean age, 66.

After the initial improvement period to 1 year after stroke, after adjusting for age, gender, education, vascular risk factors, and stroke characteristics, overall cognition and all areas declined (-0.

Recurrent stroke and advanced age are associated with faster decline

The important significance of the study is that it found that the cognitive decline of stroke patients within 1-3 years after the onset of the disease was faster than that of the control group without stroke
