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.

Lymphovenous anastomosis may be an effective treatment for Alzheimer's disease

A small but growing body of evidence suggests that a minimally invasive surgical procedure called lymphovenous anastomosis (LVA) might be an effective treatment for Alzheimer's disease (AD), according to a special article in the March issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS).

New review explores whether berries can slow cognitive decline linked to obesity

This systematic review in Nutrients evaluates human studies investigating whether polyphenol-rich berry consumption can modulate obesity-related metabolic dysfunction and support cognitive performance, particularly in individuals at risk of mild cognitive impairment. Evidence suggests modest memory benefits and possible metabolic improvements, although biomarker findings and long-term clinical relevance remain uncertain.

Study identifies PPP2R5C blood marker that may detect Alzheimer’s disease earlier

Blood test models predict when Alzheimer’s symptoms may start years in advance

Researchers developed plasma p-tau217–based clock models that estimate when cognitively unimpaired individuals with Alzheimer’s pathology may develop symptomatic disease. The models predicted symptom onset within about three to four years and may help improve clinical trial selection while remaining unsuitable for individual clinical decisions at present.
