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.

Peptide nanostructures block amyloid buildup and boost neuron survival in lab tests

Researchers developed trehalose-functionalized peptide amphiphiles (TPAs) that self-assemble into supramolecular nanostructures and demonstrated these TPAs can inhibit amyloid beta aggregation. In vitro, TPAs significantly improved survival of human neurons exposed to amyloid-induced neurotoxicity, suggesting therapeutic potential for neurodegenerative diseases.
