A study in mice and people from Washington University School of Medicine in St. Louis shows that sleep deprivation causes tau levels to rise and tau tangles to spread through the brain. Tau tangles are associated with Alzheimer's disease and brain damage.
Researchers at University of California San Diego School of Medicine report that autopsies of patients diagnosed with Alzheimer’s disease when they were alive — and confirmed by autopsy — indicate many cognitive issues symptomatic of the condition are less noticeable in living Hispanic patients.
Permanently arrested cell growth is known as "cellular senescence", and the accumulation of senescent cells may be one cause of aging in our bodies. Japanese researchers have discovered that a certain enzyme in our bodies promotes cellular senescence by producing reactive oxygen species. Drugs that target this enzyme could potentially suppress this process, and inhibit aging and aging-related illnesses.

Emergency and urgent hospitalizations are associated with an increased rate of cognitive decline in older adults, report researchers at Rush University Medical Center. Results of their study, published in the Jan. 11, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology, shows that hospitalization may be a more of a major risk factor for long-term cognitive decline in older adults than previously recognized.
Poor sleep is a hallmark of Alzheimer's disease, and now researchers at Washington University School of Medicine in St. Louis think they know why. They found that older people who have less slow-wave sleep – the deep sleep you need to consolidate memories and wake up feeling refreshed – have higher levels of the brain protein tau. Elevated tau is a sign of Alzheimer’s disease and has been linked to brain damage and cognitive decline.
Researchers from the University of Southern California have discovered that a drug currently being developed to treat stroke patients could also prevent Alzheimer’s disease.

A new study finds that some brain cells protect themselves from Alzheimer’s with a cellular cleaning system that sweeps away toxic proteins associated with the disease.
A new study from biomedical engineer Qi Wang, who is developing innovative ways of selectively activating neural circuitry to enhance perception and cognition, demonstrates a major advance in understanding how the locus coeruleus (LC) modulates information processing in the thalamus. Wang found that activating the LC improves the transmission of information about different features of sensory stimuli from the thalamus to the cerebral cortex, and subsequently perceptual performance in perceptual tasks.
UT Southwestern researchers have succeeded in neutralizing what they believe is a primary factor in late-onset Alzheimer’s disease, opening the door to development of a drug that could be administered before age 40, and taken for life, to potentially prevent the disease in 50 to 80 percent of at-risk adults.
In a study published in the journal BRAIN, neuroscientists led by Michael D.

Rutgers scientists have found a compound in coffee that may team up with caffeine to fight Parkinson’s disease and Lewy body dementia – two progressive and currently incurable diseases associated with brain degeneration.
Researchers have discovered what might be an effective strategy to prevent and combat cognitive dysfunction in obese individuals. They are the first to examine the modulatory role of an exercise-induced protein in the brain that promotes neuron survival using high-intensity interval exercise (HIIE) in obese and normal-weight subjects. Obesity reduces the expression of this protein and lower levels are associated with Alzheimer’s, Parkinson’s and obesity. HIIE upregulated this protein in the obese subjects compared to normal-weight subjects.
Researchers at Johns Hopkins Medicine have identified in live human brains new radioactive “tracer” molecules that bind to and “light up” tau tangles, a protein associated with a number of neurodegenerative diseases including Alzheimer’s disease and other related dementias.
The non-pregnant uterus is commonly assumed to be an unimportant organ. One third of American women have a hysterectomy by age 60, often before natural menopause. Arizona State University researchers have found an animal model of hysterectomy resulted in decreased memory capacity and an altered hormonal profile within two months after surgery. The study suggests an important role for the uterus that could impact cognitive aging.
