Early Odor Detection Loss Linked to Alzheimer’s Gene Variant

Individuals carrying a gene variant associated with Alzheimer's disease, APOE e4, may experience early loss in their ability to detect odors, hinting at future cognitive challenges. The study employed an at-home survey to test over 865 people's sense of smell and cognitive skills at five-year intervals.

Taking Vitamin D Could Help Prevent Dementia

Taking a vitamin D supplement daily may help stave off dementia in older adults, a new study reports. Researchers found taking vitamin D was associated with adults living dementia free for longer, and there were 40% fewer cases of dementia reported in those who frequently took vitamin D supplements. The effects were significantly greater in women than men.

Alzheimer’s Risk Gene Undermines Insulation of Brain’s ‘Wiring’

When people carry the Alzheimer's associated APOE4 gene, oligodendrocytes fail to transport fatty molecules to wrap neurons that make brain circuitry connections. This deficit of myelin may contribute to the pathology and symptoms of Alzheimer's disease.

Omega-3’s Linked to Improved Brain Structure and Cognition at Midlife

Boosting omega-3 fatty acid intake helps to preserve brain health and improve cognition in middle age, a new study reports. For those with the Alzheimer's associated APOE4 gene, omega-3 fatty acid intake was associated with greater hippocampal volume and less small vessel disease.

Common Alzheimer’s Gene Variant Linked to COVID Mortality

Mice with the Alzheimer's disease-associated APOE4 and the APOE2 genes were more likely to die from COVID-19 than those with the APOE3 gene. Those with APOE4 and APOE2 genes had more virus replication in the lungs, higher inflammation, and increased tissue damage following coronavirus infection.

How Microglia Contribute to Alzheimer’s Disease

Microglia that express the Alzheimer's associated APOE4 genetic variant are unable to effectively metabolize lipids. This causes lipids to build up, promoting inflammation and preventing effective neurotransmission.

Changes in the Retina Can Be Linked to Parts of the Brain of Healthy Subjects at Risk of Alzheimer’s

In cognitively healthy people with a genetic risk for Alzheimer's, retinal changes have been associated with alterations in the entorhinal cortex, hippocampus, and lingual gyrus. Researchers say retinal changes can be used to track changes in brain structures associated with Alzheimer's in those with genetic risk factors.

People With a High Omega-3 DHA Level in Their Blood Are at 49% Lower Risk of Alzheimer’s

People with higher levels of omega-3 DHA in their blood are 49% less likely to develop dementia than those with lower levels. Researchers say adding additional omega-3 DHA to the diet, especially in those with the Alzheimer's associated Apoe4 gene, could slow the development and progress of dementia.
