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.

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.
