Recent studies suggest that frequent television viewing during midlife is associated with smaller brain structures, while cognitively stimulating sedentary tasks do not show the same negative effects.
The World Health Organization has updated its international guidelines, identifying 14 modifiable risk factors that influence the development of dementia. These findings provide a framework for public health policy and individual cognitive health management.
Emerging research indicates that the shingles vaccine might provide neuroprotective benefits beyond preventing painful rashes, potentially reducing dementia risk in older adults.
The World Health Organization has released updated guidelines identifying modifiable health and lifestyle factors that can prevent or delay dementia. Researchers are also exploring new diagnostic blood tests and experimental drug therapies to address cognitive decline.
A study of over 214,000 individuals across 14 countries shows that dementia risk factors shift based on a nation's wealth, challenging universal prevention models.
Recent neuroimaging and cellular studies link long COVID to structural damage in the dopamine system rather than widespread brain inflammation. Researchers are now exploring whether these changes, which mirror aspects of neurodegenerative disease, could be treated with dopamine-targeting therapies.
