Dementia

Lower caffeine consumption was linked to a higher risk of memory impairment and worse Alzheimer's disease biomarkers, suggesting caffeine might offer protective effects against cognitive decline. However, more research is needed to confirm any direct benefits.

Recent longitudinal research found that older adults with mild cognitive impairment who engaged more frequently in cognitively stimulating activities maintained better memory, working memory, and attention, suggesting such activities could help slow cognitive decline.

A meta-analysis of 35 studies with over 849,000 participants found that higher fish consumption is associated with a lower risk of cognitive decline, but the link to dementia and Alzheimer’s disease remains less conclusive and requires further research.

Active social contact appears to reduce the elevated dementia risk associated with high neuroticism, with higher social interaction lowering the risk by up to 22%, according to a large-scale UK study published in the Journal of Affective Disorders.

A 15-year study reveals that depression boosts the risk of dementia by 74%.

A new study has found that patients with type 2 diabetes taking SGLT-2 inhibitors had a 35% lower risk of developing dementia compared to those on DPP-4 inhibitors, likely due to additional health benefits beyond blood glucose control.

New research suggests that exposure to artificial light at night may increase the risk of Alzheimer’s disease, particularly in younger people, highlighting light pollution as a potential factor in the rise of neurodegenerative conditions.

A 12-week study found that a daily fiber supplement improved memory in older adults by enhancing gut health, particularly increasing beneficial bacteria like Bifidobacterium. These findings suggest that gut-targeted interventions could help protect cognitive function as we age.

Researchers discovered that some brain cells age faster than others, especially in people with Alzheimer’s disease. Women’s brains also show more of these rapidly aging cells, which may increase their risk for neurodegenerative disorders.

Simple lifestyle changes can dramatically lower your risk of dementia.

Addressing 14 preventable risk factors, including vision loss and high cholesterol, could reduce global dementia cases by 45%, according to a new Lancet Commission report, emphasizing prevention and improved quality of life for those affected.

UCLA researchers have discovered a compound, DDL-920, that restores memory and cognitive function in Alzheimer’s model mice by enhancing brain gamma oscillations, offering a potential new treatment that goes beyond slowing disease progression.

Alzheimer’s disease risk is more strongly influenced by maternal genetics, with higher amyloid plaque levels in those with a maternal history of memory loss, suggesting mitochondrial dysfunction may play a key role.

Scientists have uncovered a significant clue to understanding why some individuals are more susceptible to Alzheimer’s disease.

A new study has found that genetic predispositions for neuroticism may predict the onset of Alzheimer's in individuals with amnestic mild cognitive impairment.
