- PSEN1 Mutations and Alzheimer’s: Who Should Consider Testing?
PSEN1 mutations account for 70% of inherited early-onset Alzheimer’s cases—test if family members developed dementia before age 60. - Genes Linked to Early-Onset Alzheimer’s: What Families Should Know
Genetic variants like APOE4 and rare mutations in PSEN1 or PSEN2 raise Alzheimer’s risk, but genes alone do not determine disease. - 23andMe and Alzheimer’s Risk: Testing Explained
Genetic testing can reveal Alzheimer’s risk factors, but genes alone don’t determine your future. - Genetic Testing for Alzheimer’s: Benefits
Genetic testing for Alzheimer’s identifies risk genes like APOE4, enabling earlier planning and preventive action before cognitive decline begins. - The Protective APOE2 Gene: Why Some Variants May Lower Risk
Some people’s brains are naturally protected against Alzheimer’s disease. Here’s why APOE2 carriers have a 99% lower risk than others. - The APOE4 Gene and Alzheimer’s: Key Facts
Carrying the APOE4 gene raises Alzheimer’s risk substantially, but lifestyle and medical management can modify that risk significantly. - Alzheimer’s Risk With a Family History: Key Safety Facts
Family history raises your Alzheimer’s risk, but genetics is only part of the story—lifestyle and individual resilience matter too. - Is Alzheimer’s Hereditary? What Family History Really Means
Family history increases Alzheimer’s risk but doesn’t determine your fate—genetics, lifestyle, and environment all play a role. - The Link Between Glaucoma and Alzheimer’s: Key Facts
Both conditions involve progressive neurodegeneration—glaucoma damages the optic nerve and retinal cells, while Alzheimer’s destroys neurons in the… - Cataract Surgery and Dementia Risk: Key Safety Facts
Vision from cataract surgery may help preserve cognition, but surgery itself carries delirium risks in dementia patients that require careful planning. - Blue Light and Sleep in Dementia: Key Facts
Blue light disrupts sleep in dementia patients far more severely than in healthy older adults because dementia damages the brain’s internal clock. - Nighttime Light and Alzheimer’s Risk: A Clear Guide
Nighttime light exposure disrupts your brain’s nightly waste-clearing process, increasing cognitive decline risk by nearly 50% compared to sleeping in darkness.
