Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

Alzheimer’s Disease | Definition, Causes, Diagnosis & Treatment

Alzheimer’s Disease (AD) is the most common form of dementia worldwide (60-70% of all dementia cases) and is a progressive neurodegenerative disorder.

Niigata University study updates Alzheimer's risk for APOE-e4 homozygotes

Researchers at Niigata University have conducted the first comprehensive reappraisal in nearly 30 years of the risk of Alzheimer's disease (AD) associated with APOE-e4 homozygosity (e4*4) in the Japanese population.

Blood metabolism maps how lifestyle tracks function in cognitive aging

A new study used pathway-level blood metabolomics to identify lifestyle-associated metabolic patterns linked to physical, cognitive, and daily functional performance across CN, MCI, and AD. The findings suggest that diet- and activity-linked pathway signals span energy, amino acid, lipid, inflammatory, oxidative stress, and microbiome-related metabolism, but require independent and longitudinal validation.

Extreme heat and cold threaten health of people with dementia

Exposure to extreme heat and cold is associated with an increased risk of emergency department (ED) visits among people living with dementia, according to preliminary research presented today at the European Academy of Neurology (EAN) Congress 2026.

Scientists discover how Arc protein spreads Alzheimer's brain pathology

Alzheimer's disease is driven by a buildup of a toxic protein called Tau that kills neurons. As toxic Tau spreads to new regions of the brain, symptoms become worse and ultimately fatal.

Hearing aids may lower dementia risk in adults with epilepsy and hearing loss

Adults with both epilepsy and hearing loss who use hearing aids may have a 23% lower risk of developing dementia than those who do not, according to new research presented at the European Academy of Neurology (EAN) Congress 2026.

Blood metabolites reveal lifestyle links to brain health before dementia

Blood metabolome profiling in dementia-free middle-aged adults linked 14 metabolites to cognition and 22 metabolites to MRI markers of brain health. Lifestyle, clinical factors, medication use and gut microbiota appeared to shape many of these metabolites, with ergothioneine emerging as a notable cognition-linked signal.

Iron overload gradually increases neurons' vulnerability to neurodegeneration

Neurodegenerative diseases affect tens of millions of people worldwide. Among these, Alzheimer's and Parkinson's diseases are the most common; in the United States alone, the Alzheimer's Disease Association and Parkinson's Foundation report roughly 7 million people with Alzheimer's and another million with Parkinson's.
