Study says stressful experiences at a young age linked to Alzheimer's

Stressful life experiences can age the brain, and may explain the higher rates of Alzheimer's disease among African Americans, according to researchers from Wisconsin University's school of medicine and public health.

The study: Researchers gave a series of neuropsychological tests to over 1,300 people who identified as having stressful life experiences such as losing a job, living with an abusive or drug-addicted parent, poverty, or death of a child. They tested for immediate memory, verbal learning and memory, visual learning and memory, and story recall.

The results: They concluded that a stressful event in someone's early years causes poor cognitive functioning later in life. Further, African Americans reported 60% more stressful events throughout their lives. The researchers say each of those stressful events is equal to four years of cognitive aging.

Keep in mind: The research was presented at the Alzheimer's Association international conference in London, but has not yet been peer reviewed. In addition, of the nearly 1,300 participants, only 82 were African American. Doug Brown, the director of research at the Alzheimer's Society, told The Guardian, that while they are aware that stress can impact a person's health later in life, the direct link between these events and an increased risk of dementia needs to be studied further.

President Trump said on Saturday he is considering a "short term" quarantine of New York, New Jersey and parts of Connecticut — areas congruent with the New York metro area, the epicenter of the novel coronavirus in the U.S.

Reality check: These states have already taken steps to quarantine residents and promote social distancing to combat COVID-19. The governors of New York and New Jersey issued statewide stay-at-home orders last week, and non-essential businesses in Connecticut were ordered to close as of this Monday.

New York is latest state to delay primary due to coronavirus

New York — the epicenter of the coronavirus outbreak in the U.S. — has moved its presidential primary to June 23, Gov. Andrew Cuomo said on Saturday.

Why it matters: 23 other states and the District of Columbia haven't held primaries yet. The White House is recommending, for now, that Americans practice social distancing and gather in groups of no more than 10 people — while many states have issued stay-at-home orders.
