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

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

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

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.

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.

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.

Scientists may have learned why opioids depress breathing while relieving pain. The finding could lead to pain drugs that don't cause respiratory failure, the usual cause of death in opioid overdoses.

The virus that causes COVID-19 can cause strokes, inflammation, oxygen deprivation and infection in the brain. And each of these may lead to long-term neurological problems.

Scientists are beginning to understand how COVID can cause brain injuries. The virus can lead to a stroke, starve the brain of oxygen, cause inflammation brain and might infect and kill brain cells.

A new Alzheimer's drug isn't reaching many patients. Doctors say reasons include its high cost, and lingering questions about its effectiveness.

A concussion can make it difficult to converse in a noisy room. Scientists say that's because the injury has impaired the brain's ability to process sounds.

People who sustain a concussion can develop an unusual hearing problem. Their ears work fine, but their brain struggles to process sounds.

Scientists have created detailed maps of the brain area that controls movement in mice, monkeys and people. The maps could help explain human ailments like Alzheimer's and Lou Gehrig's disease.

Two scientists who helped explain how we sense temperature and touch have received the Nobel prize in physiology or medicine. Their research could lead to new pain treatments.

Intensive rehabilitative therapy that starts two to three months after a stroke may be key to helping the injured brain rewire, a new study suggests. That's later than covered by many insurance plans.

The visual problem is usually treated in kids by temporarily covering the other eye with a patch. But that doesn't always work. Research now shows crucial brain rewiring can happen in adulthood, too.

The surf is always up in Waco, Texas, thanks to an artificial wave so good it's attracting top professionals and casual riders. It's a sign of just how far the technology of wave making has come.

The reason Waco has become a must-visit for surfers from around the world, is a surf park with state-of-the-art artificial waves. It can make 120 waves an hour and costs surfers about $10 a ride.

Alzheimer's researchers are trying new treatment approaches, including trying to boost the immune system, remove toxic tangles of protein and stimulate brain waves with light and sound.

Weeks after the Food and Drug Administration approved the Alzheimer's drug Aduhelm, doctors are struggling to figure out who should get the drug and how to use it safely.
