Brain scans may reveal a lot about mental illness, but not until studies get bigger

Tuesday, April 26, 2022

Scientists are using MRI scans to understand how mental illness shows up in the bran. But new research raises concerns that existing studies are not reliable because the sample sizes are too small.


Brain scan studies need to get much bigger to offer insight into mental illness

Monday, April 25, 2022

Researchers say most brain scan studies are too small to explain complex human traits like intelligence or mental health. Meaningful insights will require studies of thousands of brains, not dozens.


A lead COVID test investigator on how well at-home rapid tests work for BA.2

Monday, April 25, 2022

NPR's Mary Louise Kelly talks with Dr. Wilbur Lam, a lead investigator assessing COVID-19 diagnostic tests for the U.S. government, about detecting the omicron BA.2 subvariant with rapid tests.


Encore: Concussions don't necessarily hurt your ears, but they can hurt your hearing

Tuesday, April 19, 2022

People who sustain a concussion can develop an unusual hearing problem. Their ears work fine, but their brain struggles to process sounds. (Story first aired on All Things Considered on Nov. 3, 2021.)


Medicare has decided to sharply limit coverage of Aduhelm, a new Alzheimer drug

Friday, April 08, 2022

Medicare officials announced on Thursday that the health insurance program for older Americans will sharply limit coverage of a costly and controversial new Alzheimer's drug.


Scans reveal the brain's early growth, late decline and surprising variability

Thursday, April 07, 2022

A study of more than 120,000 brain scans shows rapid growth before age 2 and accelerating decline after age 50. The results may one day help pick up abnormalities in the developing brain.


In jumpy flies and fiery mice, scientists see the roots of human emotions

Wednesday, April 06, 2022

Scientists are trying to understand PTSD and other human disorders by studying emotion-related brain circuits in animals, which research suggests may have a lot in common with the human brain.


This form of memory loss is common — but most Americans don't know about it

Friday, March 18, 2022

Mild cognitive impairment, a common brain condition, can be an early sign of Alzheimer's disease. But most people don't know the symptoms. And some may mistake it for normal aging.


Why its important for more Americans to know about mild cognitive impairment

Wednesday, March 16, 2022

Mild cognitive impairment, a condition that may be a precursor to Alzheimer's disease, affects more than 12% of people 60 and up. Yet a survey found 82% of Americans know little or nothing about it.


Do masks in school affect kids' speech and social skills?

Tuesday, March 15, 2022

Scientists say that for most children, masks in school aren't a major obstacle to learning or socializing. Students in classrooms find other ways to connect.


Experts weigh in: Do masks interfere with a child's ability to learn or socialize?

Monday, March 14, 2022

Some parents have argued that masks need to come off in schools because it affects kids' speech and social development. Is that really true? Researchers address this question from several angles.


Art and music therapy seem to help with brain disorders. Scientists want to know why

Saturday, February 19, 2022

Arts therapies appear to ease brain disorders from Parkinson's to PTSD. Now, artists and scientists have launched an effort to understand how these treatments change the brain.


Watch these robotic fish swim to the beat of human heart cells

Thursday, February 10, 2022

Tiny, robotic fish powered by human heart cells suggest that scientists are getting closer to their goal of building replacement hearts from living tissue.


A brain circuit tied to emotion may lead to better treatments for Parkinson's disease

Monday, February 07, 2022

The symptoms of Parkinson's disease can vanish briefly in the face of stress or a strong emotion. Now scientists are searching for a treatment based on this phenomenon, a form of the placebo effect.


Thirsty? Here's how your brain answers that question

Thursday, January 27, 2022

Scientists have shown that the brain uses multiple checkpoints to make sure we get enough water, but not too much.


The brain science behind deciding to drink when you're thirsty is pretty complicated

Wednesday, January 26, 2022

It feels simple: When we're thirsty, we drink. But the brain science explaining that simple decision turns out to be very complicated.


Medicare considers covering expensive Alzheimer's drug for those in clinical trials

Wednesday, January 12, 2022

Under a proposal announced Tuesday, Medicare would cover the expensive and controversial Alzheimer's drug Aduhelm — but only for those participating in clinical trials.


What crying baby mice could teach us about human speech

Friday, January 07, 2022

Scientists have found a cluster of rhythmic brain cells in newborn mice that may explain why spoken languages around the world share a common tempo.


ICU teams report fatigue and frustration as they brace for omicron surge

Friday, December 31, 2021

A resurgence in COVID-19 cases is testing the endurance of health care workers who care for the sickest patients, most of whom are unvaccinated.


A brain circuit linking pain and breathing may offer a path to prevent opioid deaths

Wednesday, December 22, 2021

Opioids can kill because they reduce breathing along with pain. Now brain scientists have made a discovery that could lead to potent pain drugs that don't affect breathing.
