Everyday tasks — such as buttoning a shirt, opening a jar or brushing teeth — can suddenly seem impossible after a stroke that affects the brain’s fine motor control of the hands. New research suggests starting intensive rehab a bit later than typically happens now — and continuing it longer — might improve recovery.

Charles Krupa/AP Nearly two months after the Alzheimer’s drug Aduhelm received conditional approval from the Food and Drug Administration, experts are still debating how, and whether, it should be used. A few doctors and medical institutions say they have no plans […]
In a decision that has sparked controversy, the Food and Drug Administration approved Aduhelm, an Alzheimer’s treatment, on June 7. The agency disregarded a recommendation against approval by a panel of independent experts, several of whom resigned in protest.

NeuroLutions People recovering from a stroke will soon have access to a device that can help restore a disabled hand. The Food And Drug Administration has authorized a device called IpsiHand, which uses signals from the uninjured side of a patient’s brain to help rewire circuits controlling the hand, wrist and arm. The device can be used at home and offers stroke patients “an additional treatment option to help them move their hands and arms […]

Fragile X syndrome involves changes in the X chromosome, seen in the four columns of chromosomes starting on the left. Two normal X chromosomes are shown in the far-right column. Richard J. Green/Science Source An experimental drug intended for Alzheimer’s patients seems to improve both language and learning in adults with Fragile X syndrome. The drug, called BPN14770, increased cognitive scores by about 10% in 30 adult males after 12 weeks, a team reports in the journal Nature Medicine. That is enough to change the lives of many people with Fragile X, says Mark Gurney, CEO of Tetra Therapeutics, developer of […]

Ley Uwera for NPR At an animal sanctuary in the Congo, several dozen Congolese schoolchildren are getting a crash course in bonobos. These gentle, endangered apes, who resemble chimpanzees, are “our closest cousins,” educator Blaise Mbwaki tells the students in French. “They have a human character, and they are Congolese.” “So if you eat a bonobo,” Mbwaki says, “you are eating your cousin.

Recruiting patients for medical studies has been challenging during the pandemic, especially older people who are more vulnerable to COVID-19. Dra_Schwartz/Getty Images hide caption toggle caption Dra_Schwartz/Getty Images Recruiting patients for medical studies has been challenging during the pandemic, especially older people who are more vulnerable to COVID-19. Dra_Schwartz/Getty Images Medical research was an early casualty of the COVID-19 pandemic. After cases began emerging worldwide, thousands of clinical trials unrelated to COVID-19 were paused or canceled amid fears that participants would be infected. But now, some researchers are finding ways to carry on in spite of the coronavirus. “It’s been a […]
