Article Synopsis
- Poststroke cognitive impairment is common, but the exact changes in cognitive function following a first stroke compared to pre-stroke levels are not fully understood.
- The study aimed to track cognitive performance over time in stroke survivors versus individuals without strokes, using data from 14 international cohorts of older adults.
- Results showed that incident stroke led to a significant immediate drop in overall cognitive skills and accelerated decline in cognitive abilities over time.
Article Synopsis
- The study investigates how cardiometabolic multimorbidity (CMM) and depression affect cognitive function in older adults, aiming to understand their individual and combined impacts.
- It harmonizes data from 14 international cohort studies and utilizes various scales to assess CMM and depression among participants who did not have dementia at the start of the study.
- Findings include the analysis of over 30,000 older adults, revealing that both CMM and depression are linked to cognitive decline, with further validation through additional studies across different settings.
Article Synopsis
- Previous studies suggest that using antihypertensive medication in older adults may lower the overall risk of dementia, but the effects on different types of dementia, particularly Alzheimer’s disease (AD), are still uncertain.
- This research analyzed data from over 31,000 participants across multiple countries, focusing on how history of hypertension and blood pressure levels impact the risk of developing AD and non-AD types of dementia.
- The findings indicated that untreated hypertension significantly increases the risk of developing AD and non-AD dementia compared to healthy individuals, while treated hypertension showed a similar risk for non-AD but not a significant difference between treated and untreated groups.
Article Synopsis
- A study involving 7,801 older adults examined the connection between fruit and vegetable consumption and the development of depression, finding that higher fruit intake was linked to a lower risk of depression.
- Over a follow-up period of 3 to 9 years, 21% of participants developed depression, with fruit intake showing a significant protective effect, while vegetable intake did not show a notable association.
- The authors noted limitations due to varied measurement methods and the relatively modest sample size, suggesting further research is needed on fruit and vegetable consumption in larger, more standardized studies among older adults in low- and middle-income countries.
