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.

Menopause may raise women’s Alzheimer risk earlier than doctors once thought

This review argues that women’s higher Alzheimer disease risk may be shaped in part by midlife neuroendocrine aging, especially the menopause transition, rather than by longevity alone. It highlights early menopause, bilateral oophorectomy, vasomotor symptoms, and midlife cognitive changes as underinvestigated but potentially important risk markers, while calling for sex-specific, biomarker-driven prevention strategies.

Study links financial strain to faster cognitive aging

Worse financial well-being in midlife and older age -and especially declines over time-are associated with lower memory scores and faster cognitive decline, reports a new study at Columbia University Mailman School of Public Health.

Targeting protein fragment may improve Huntington disease treatments

Treatments that target a fragment of the mutant protein that causes Huntington's disease might be more effective than treatments, now in clinical trials, that target the whole protein but leave this fragment intact, a new study in mice suggests.

New data platform transforms prediction and understanding of Alzheimer’s disease

A powerful new real-world data platform could transform how scientists predict and understand Alzheimer's disease and Alzheimer's disease related dementias (AD/ADRD), reports a new study at Columbia University Mailman School of Public Health and collaborators at the Vagelos College of Physicians and Surgeons, the School of Nursing as well as the University of Miami and University of Chicago.

Study finds common brain mechanism behind different anesthesia drugs

When patients undergo general anesthesia, doctors can choose among several drugs. Although each of these drugs acts on neurons in different ways, they all lead to the same result: a disruption of the brain's balance between stability and excitability, according to a new MIT study.
