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.

Synthetic torpor moves closer to real-world medical use

Nature is often the best model for science. For nearly a century, scientists have been trying to recreate the ability of some mammals and birds to survive extreme environmental conditions for brief or extended periods by going into torpor, when their body temperature and metabolic rate drop, allowing them to preserve energy and heat.
