Secondary infections and novel inflammatory events, even ones that occur external to the brain, amplify the brain's immune response and detrimentally impact cognition in mouse models of Alzheimer's disease.
Obesity has been linked to severely restricted blood flow in the brain. Reduced blood flow in the brain, or cerebral hypoperfusion, can be an early indicator of vascular dementia and Alzheimer's disease.
Older adults with higher fear of memory loss and dementia report a significant decrease in their quality of life and reported more failures in memory.
