The study identifies shortcomings in specialist diagnosis, diagnostic scanners, and infusion centers, and recommends measures to prepare for an Alzheimer's therapy.
A registry-based study from Aarhus University found that heart attack survivors are at a higher risk of developing vascular dementia, which is caused by vascular damage in the brain. The risk remains elevated for up to 35 years after the heart attack, with patients who underwent bypass surgery showing a fourfold increased risk.

The study of 281 deceased patients revealed a significant difference in the manifestation of aggression between the two groups.
Researchers found patients with FTD showed thinning of outer retina compared to control subjects. The degree of retinal thinning was worse in those with lower cognition scores.

A new simulation study shows that dementia can more than double the healthcare expenditure of aging individuals, with the majority of the financial burden falling on family members. The total average cost to care for a person with dementia was $321,000 over five years, compared to $137,280 without dementia.
Researchers detect granulins inside cells for the first time, suggesting a potential FTD treatment strategy by targeting lysosomal function. The discovery may have therapeutic potential for Alzheimer's disease and Parkinson's disease as well.
A recent study found that 44% of nursing home residents with dementia were taking PIMs at admission, and many stopped or started these medications during their stay. The researchers suggest a person-centered approach to discontinuing PIMs, especially for frail older adults.
Greater intraindividual reaction time variability was found to predict shorter survival times in older adults, independent of cognitive decline. The study used computerized reaction time tests to measure participants' responses and found that increased variability was associated with a higher risk of mortality.
A cohort of 861 adults aged 70-90 years showed that greater reaction time variation predicted all-cause mortality. The findings suggest that reaction time variability could be an independent marker for predicting shorter time to death, even when accounting for other risk factors.
Researchers stopped FUS protein clumping using phosphorylation, a natural cellular process that increases protein charge and repels aggregation. The findings could have positive implications for treating ALS and dementia.
Researchers found that people with high blood pressure variability are more likely to develop dementia and Alzheimer's disease. Home monitoring of blood pressure may be a useful tool for assessing future dementia risk.
