Alzheimers-113015.jpg 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.

Terrier-113015.jpg 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.

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.
