People who experience their first-ever bout of depression after having a heart attack are at greater risk for future heart problems than are patients who either don?t become clinically depressed after the medical emergency or who were depressed even before the incident, new research shows.
A new study compared a humpback whale brain with brains from several other cetacean species and found the presence of a certain type of neuron cell that is also found in humans. This suggests that certain cetaceans and hominids may have evolved side by side.
Researchers have linked chemotherapy with short-term structural changes in cognitive areas of the brain, according to a new study.

Alcohol can help people initially fall asleep, but leads to poor-quality sleep later in the night. Escalated consumption of alcohol to aid sleep can lead to alcoholism. Inaccurate sleep perceptions among alcoholics in early recovery may predict relapse to drinking.
Popular and clinical lore support the strong connection between smoking and alcohol consumption. Adolescent smokers appear to have a greater vulnerability to developing alcohol-use disorders. Results indicate that smoking “primes” the brain for subsequent addiction to alcohol and possibly other drugs.

A new study has shown that exercise can reduce sleep-disordered breathing in children, which appeared in the November issue of Obesity. Exercise can reduce snoring among overweight children, even if it doesn’t result in weight loss.
