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.

Does motherhood influence brain aging? New research suggests a positive cognitive association

Longitudinal data from postmenopausal women suggest that cumulative pregnancy duration and breastfeeding history are associated with modestly better cognitive performance later in life. These associations reflect higher cognitive trajectory levels rather than proven slowing of decline, and causality remains uncertain.
