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.

Sex-based differences and role of BMP signaling in neurogenesis in Alzheimer's mice models

Alzheimer's disease (AD) is a serious neurodegenerative disease largely affecting older adults. Apart from age, it also shows sex-based differences, with women being more at risk. However, the origin of these differences remains unknown.

APOE gene: A major driver in Alzheimer's disease

Potentially more than 90% of Alzheimer's disease cases would not occur without the contribution of a single gene (APOE), according to a new analysis led by UCL researchers.

Homeless shelters for seniors pop up, catering to older adults’ medical needs

Just outside Salt Lake City sits an old, two-story, brick hotel. It's been given new life as a homeless shelter for seniors. The Medically Vulnerable People shelter — or MVP shelter, as it's known — is for people 62 and older or for younger adults with chronic health issues.

Restoring brain energy balance reverses advanced Alzheimer’s disease in mouse models

For over a century, Alzheimer's disease (AD) has been considered irreversible. Consequently, research has focused on disease prevention or slowing, rather than recovery.

Simple drug treatments could help older brains cope with memory decline and postoperative recovery

Simple pharmaceutical interventions could help older brains cope with memory impairment and recovery after surgery, new studies in mice suggest.

Finger-prick blood test shows promise for detecting Alzheimer’s disease biology

Finger-prick dried blood sampling can accurately measure key Alzheimer’s disease biomarkers, including p-tau217, GFAP, and NfL, showing strong concordance with venous plasma and meaningful associations with CSF pathology. While analytical limitations remain, this minimally invasive approach shows promise as a scalable research and screening tool within biomarker-based diagnostic pathways.

Two isoforms of a cellular energy sensor play distinct, opposing roles in Alzheimer's disease

A comprehensive mini-review published today after peer review in Brain Medicine by Dr. Tao Ma and colleagues at Wake Forest University School of Medicine synthesizes emerging evidence that two isoforms of a critical cellular energy sensor play distinct, and sometimes opposing, roles in Alzheimer's disease.

Common blood signals explain why chronic diseases cluster as we age

This population-based study shows that shared and pattern-specific blood biomarkers reflect biological vulnerability underlying multimorbidity and the pace at which chronic diseases accumulate in older adults. Metabolic and systemic stress markers such as GDF15, HbA1c, cystatin C, and insulin consistently tracked higher disease burden and faster accumulation, with findings replicated across cohorts.
