CNN (1/22, Howard ) reports, “Testing a person’s blood for a type of protein called phosphorylated tau, or p-tau, could be used to screen for Alzheimer’s disease with ‘high accuracy,’ even before symptoms begin to show, a new study suggests.” The research “involved testing blood for a key biomarker of Alzheimer’s called p-tau217, which increases at the same time as other damaging proteins — beta amyloid and tau — build up in the brains of people with the disease.” The “simple blood test was found to be up to 96% accurate in identifying elevated levels of beta amyloid and up to 97% accurate in identifying tau.” The findings were published in JAMA Neurology.

The Hill (1/22, Sforza ) also covers the story.

HealthDay (1/19, Thompson ) reported, “People coming off antidepressants often struggle with emotional and social turmoil, especially if they quit their meds cold turkey, a new study” indicated. The study, in which investigators “conducted interviews with 20 people who had attempted within the past year to withdraw from SSRI…antidepressants,” found that “challenges reported by patients quitting antidepressants included feeling overwhelmed by their emotions, finding social situations less enjoyable, and feeling detached and less empathetic towards others.”

The findings were published in Health Expectations.
