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 suggests spatial memory decline may be preventable and not universal

In the realm of memories, "where" holds special importance. Where did I leave my keys? Where did I eat dinner last night? Where did I first meet that friend? Recalling locations is necessary for daily life, yet spatial memory - which keeps track of "where" - is one of the first cognitive abilities to fade in old age. And deficits earlier in life can be a telltale sign of dementia.

Study links high neuroinflammation in young people with Down Syndrome to Alzheimer's risk

Down syndrome is associated with accelerated aging. It is estimated that up to 90% of individuals with the condition develop Alzheimer's disease before the age of 70. A study by researchers at the University of São Paulo (USP) in Brazil identified high levels of neuroinflammation in young individuals with Down syndrome, an additional factor explaining the high prevalence of Alzheimer's disease in older people with the condition. The discovery paves the way for strategies to prevent and monitor the disease.
