New data on the loss of brain synapses during Alzheimer's disease could help lead to a cure for the illness, according to researchers at Neuroscience Research Australia and the Dementia Research Unit of the UNSW School of Medical Sciences. "One of the first signs of Alzheimer's disease is the loss of synapses - the structures that connect neurons in the brain," said the study leader.
Children who grow up with dogs in their household are likely to suffer from less anxiety than those who don't, according to a new study from researchers at the Bassett Medical Center in New York.

Alzheimer's can be detected in neural tissue 20 to 30 years before one first starts noticing lapses in memory, according to new research. According to Harvard's Rudy Tanzi, when brain cells, known as glia, sense the death of other brain cells from plaques and tangles, they assume one thing: infection. In an attempt to fight these "foreign invaders" the brain becomes flooded.
A new study suggests that talk therapy is better than light-box therapy in preventing relapses of Seasonal Affective Disorder.

Interrupted sleep could have a negative impact on mood, according to a new study from researchers at the Johns Hopkins University School of Medicine in Baltimore. For the study the researchers collected data from 62 otherwise healthy men over the course of three nights. Each of the men were split into one of three groups—uninterrupted sleep each night and delayed bed times.
