Alzheimer's Disease

The olfactory system offers a direct pathway to the brain's memory and emotion centers. Now, scientists find this connection may also serve as a crucial diagnostic window into long-term neurological health, preceding traditional clinical symptoms.

A recent paper details a new mechanism for protecting the brain from Alzheimer's-related damage. The research shows how the metabolite NAD+ helps repair cellular function and improve memory.

New research reveals how Alzheimer's disease extends beyond the brain, potentially disrupting the body's energy management system.

A study of dolphins stranded in Florida suggests that repeated exposure to algal toxins may trigger brain changes associated with Alzheimer’s disease.

An individual's genetic tendency for elevated levels of a key protein in the blood signal a heightened risk for developing Alzheimer's disease, according to new research.

A new study offers a surprising look at the link between physical activity and the proteins that build up in the brains of people with Alzheimer's disease.

Women are more often diagnosed with Alzheimer’s disease, but why? New research challenges a common assumption about brain aging, pointing scientists toward other potential explanations for this well-known disparity.

A novel treatment for Alzheimer's doesn't attack brain plaques directly. Instead, it repairs a critical protective barrier, leading to remarkable recovery in animal models and offering a new direction for future therapies.

Inhaled CBD reduced inflammation and improved cognition in mice with Alzheimer’s, according to a study in eNeuro, pointing to a promising immune-based approach for treating the disease beyond traditional amyloid-focused therapies.

New research suggests that higher iron levels in specific brain regions may help identify who is at risk for developing memory problems years before symptoms emerge. The findings may offer a new way to track Alzheimer’s risk using MRI scans.

New research suggests the Mediterranean diet may be especially powerful for those at high genetic risk for dementia. The study found this diet more effectively modulates dementia-related blood metabolites, offering a targeted strategy for prevention in susceptible individuals.

Researchers have discovered that an oral dose of sodium benzoate, a widely used food preservative, lowers Alzheimer's-related amyloid proteins in patients. This finding points toward a potentially safe and convenient treatment option compared to current infusion-based therapies for the disease.

New research using UK Biobank data suggests that people with a higher genetic risk for Alzheimer’s disease may actually report less social isolation and stronger family relationships in midlife, challenging the idea that risk for dementia always reduces social connection.

A new study pinpoints where and when the earliest signs of Alzheimer’s disease begin. Researchers discovered a marker for brain inflammation rises in a specific memory-related brain region, coinciding precisely with the appearance of the disease’s first toxic plaques.

For the first time, researchers have directly linked air pollution to the physical hallmarks of Alzheimer’s disease in human brain tissue. An autopsy study found individuals from more polluted areas had significantly more amyloid plaques and tau tangles, worsening their...
