"Perhaps altruism did not grow out of a warm-glow feeling of doing good for others, but out of the simple recognition that that thing over there is a person that has intentions and goals. And therefore, I might want to treat them like I might want them to treat myself," explained study author Scott Huettel, an associate professor of psychology at Duke University Medical Center, in Durham, N.C.

Why Do Good? Brain Study Offers Clues

The gene — SORL1 — stands out because it's been tested in four ethnic groups and a form of it seems to confer a risk in all of them — including North Europeans, Caribbean Latinos, African Americans and Israeli Arabs.

Gene contributes to Alzheimer's risk

The Ohio State researchers are among many investigating the effects of marijuana ingredients on Alzheimer's, which progressively damages areas of the brain involved in memory, judgment, language and behavior. Reports from various investigators indicate there might be more than one therapeutic component of marijuana against Alzheimer's.

The researchers analyzed the hairs' carbon and nitrogen levels, which they say reflect the women's current diets. The test was 80% accurate in identifying women with anorexia and women with both anorexia and bulimia.

Hair May Help Reveal Eating Disorders

This is alarming news, considering that as many as one quarter of all Alzheimer's patients in nursing homes are on these antipsychotics. Physicians often prescribe these drugs to Alzheimer's patients off-label even though they are not approved to treat the disease.

None of the antipsychotic drugs is currently approved for Alzheimer's disease, and several short-term industry-sponsored clinical trials have failed to show a benefit. The FDA has required prominent "black box" warnings on the drugs' labels about side effects in elderly people following cases where the drugs were associated with strokes and death.

Little Benefit Seen in Antipsychotics Used in Alzheimer's

Not too long ago, Dennis Quaid admitted to suffering from anorexia. He said: “My arms were so skinny that I couldn’t pull myself out of a pool."

So what causes manorexia?

"You have these magazines where they're telling you this is the in thing. This is the in thing to wear. This is the way to look. This is the way to wear your hair. This is the way to get your six-pack abs. This is the way to get girls' attention. This is the way to be hunky and sexy," [Craig] Laue said. "At what cost?"

'Manorexia' Is On The Rise

In people with FTD, the frontal and temporal lobes of the brain shrink and their behavior changes. They may become fixated on sex or engage in criminal behavior, and they eventually die from the disorder. Lou Gehrig's disease, or amyotrophic lateral sclerosis (ALS), would seem like a different beast, given that it causes degeneration in motor neurons. But in recent years neurologists have observed that people with one of the conditions tend to get the other.

Q: Why did you call your book The Last Normal Child?

A: Because I had this fantasy, as more and more normal kids get psychiatric medication, that eventually the last normal child in the world finally would be brought to me for a prescription.

Parents push the new abnormal

The study found that daughters whose HLA-B genes closely matched their mothers' HLA-B genes were 70 percent more likely to develop schizophrenia than other children. If this risk factor could be removed, up to 12 percent of cases of schizophrenia in daughters might be prevented, the researchers said.

"When people can establish a secure and long-lasting intimate relationship, everything tends to be better for everybody," said Barry Ginsberg, a child and family psychologist and director of the Center of Relationship Enhancement in Doylestown, Penn.

Marriage Boosts Parents' Mental Health

It's known that stroke survivors who are not depressed live longer and have higher-quality lives than those who are depressed, the researcher pointed out. "Consequently, educating physicians, stroke survivors and their families about the risk of depression after stroke may increase identification of depression and lead to improved treatment."

Depression often goes untreated after a stroke

The film stars Jeremy Sisto and he's so good he convinces you he actually has multiple personalities. If you ever saw him as Billy on Six Feet Under, you know how good he is at going to the darker places of his characters' minds.
