Mental illness can run in families. And Dr. Kafui Dzirasa grew up in one of these families.

His close relatives include people with schizophrenia, bipolar disorder and depression. As a medical student, he learned about the ones who'd been committed to psychiatric hospitals, or "went missing" and were discovered in an alleyway.

Dzirasa decided to dedicate his career to "figuring out how to make science relevant to ultimately help my own family."

Out-of-body experiences are all about rhythm, a team reported Wednesday in the journal Nature.

In mice and one person, scientists were able to reproduce the altered state often associated with ketamine by inducing certain brain cells to fire together in a slow, rhythmic fashion.

Some mighty mice have overcome one of the major obstacles to interplanetary space flight: muscle and bone loss.

The mice got a drug that prevented the usual decreases in muscle and bone mass during a month on the International Space Station, a team reports in the journal Proceedings of the National Academy of Sciences.

A combination of two experimental drugs appears to slow the decline of patients with amyotrophic lateral sclerosis, an illness often known as ALS or Lou Gehrig's disease.

A six-month study of 137 patients with a fast-progressing form of the disease found that those who got daily doses of a two-drug combination called AMX0035 scored several points higher on a standard measure of function, a team reports in the Sept. 3 issue of The New England Journal of Medicine.

COVID-19 forced Keriann Wilmot's son to trade his classroom for a computer. It was a tough transition for a 10-year-old with attention deficit hyperactivity disorder.

"It was a different environment for him," Wilmot says. "He wasn't used to this kind of work from school coming in the format of an email in his Chromebook every single day."

The Food and Drug Administration has approved a variant of the anesthetic and party drug ketamine for suicidal patients with major depression.

The drug is a nasal spray called Spravato and it contains esketamine, a chemical cousin of ketamine.

This is the story of a fatal genetic disease, a tenacious scientist and a family that never lost hope.

Conner Curran was 4 years old when he was diagnosed with Duchenne muscular dystrophy, a genetic disease that causes muscles to waste away.

Conner's mother, Jessica Curran, remembers some advice she got from the doctor who made that 2015 diagnosis: "Take your son home, love him, take him on trips while he's walking, give him a good life and enjoy him because there are really not many options right now."

For years, public health officials have been trying to dispel the myth that people who get a flu shot are more likely to get Alzheimer's disease.

They are not. And now there is evidence that vaccines that protect against the flu and pneumonia may actually protect people from Alzheimer's, too.

The same process that causes dew drops to form on a blade of grass appears to play an important role in Alzheimer's disease and other brain diseases.

Scientists are monitoring the virus that causes COVID-19 for genetic changes that could make a vaccine ineffective. But so far, they're not seeing any.
