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.

Study demonstrates profound anhedonia in people with frontotemporal dementia

People with early-onset dementia are often mistaken for having depression and now Australian research has discovered the cause: a profound loss of ability to experience pleasure - for example a delicious meal or beautiful sunset - related to degeneration of 'hedonic hotspots' in the brain where pleasure mechanisms are concentrated.

Imbalanced bacterial community in the gums linked to Alzheimer's disease biomarker

Older adults with more harmful than healthy bacteria in their gums are more likely to have evidence for amyloid beta--a key biomarker for Alzheimer's disease--in their cerebrospinal fluid (CSF), according to new research from NYU College of Dentistry and Weill Cornell Medicine.

Study shows intricate association of aluminum in the neuropathology of familial Alzheimer's disease

This study builds upon two earlier published studies (Mold et al., 2020, Journal of Alzheimer's Disease Reports) from the same group. The new data, also published in the Journal of Alzheimer's Disease Reports, demonstrate that aluminum is co-located with phosphorylated tau protein, present as tangles within neurons in the brains of early-onset or familial Alzheimer's disease (AD).
