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.

99% of COVID-19 deaths in Italy occur among those not fully vaccinated

In a new report out of Italy, health officials reported that almost 99 percent of people who have died from COVID-19 since February 2021 were not fully vaccinated. The report released by the National Health Institute (ISS) showed that the few fully vaccinated people who died of COVID-19 were also older than those who died without complete COVID-19 vaccine doses.

People with metabolic syndrome may be at higher risk for second stroke, death

People with larger waistlines, high blood pressure and other risk factors that make up metabolic syndrome may be at higher risk for having a second stroke and even dying than people who do not have metabolic syndrome, according to a meta-analysis published in the July 28, 2021, online issue of Neurology, the medical journal of the American Academy of Neurology.

Research provides insights into how the hippocampus contributes to memory storage in the cortex

A new MIT study of how a mammalian brain remembers what it sees shows that while individual images are stored in the visual cortex, the ability to recognize a sequence of sights critically depends on guidance from the hippocampus, a deeper structure strongly associated with memory but shrouded in mystery about exactly how.

‘Social prescribing’ may help lonely older adults to avoid harmful sedatives and painkillers

Lonely, older adults are nearly twice as likely to use opioids to ease pain and two-and-a-half times more likely to use sedatives and anti-anxiety medications, putting themselves at risk for drug dependency, impaired attention, falls and other accidents, and further cognitive impairment, according to a study by researchers at UC San Francisco.

Brain’s locus coeruleus may be a sophisticated regulator of learning and behavior

Small and seemingly specialized, the brain's locus coeruleus (LC) region has been stereotyped for its outsized export of the arousal-stimulating neuromodulator norepinephrine.

Study reveals calcium's role in directing blood flow in the brain

Unlike the rest of the body, there is not enough real estate in the brain for stored energy. Instead, the brain relies on the hundreds of miles of blood vessels within it to supply fresh energy via the blood. Yet, how the brain expresses a need for more energy during increased activity and then directs its blood supply to specific hot spots was, until now, poorly understood.
