Brain size may one day be able to indicate if a person is prone to Alzheimer's disease or not. A new study has reveled that the brain of Alzheimer's sufferers starts shrinking 10 years before the onset of the memory-robbing disease.

Intelligence poorly related to brain size

London -- British scientists say they've found brain size is much less related to the complexity of an organism's thought and behavior than is currently assumed.

Professor Lars Chittka of the Queen Mary's Research Center for Psychology at the University of London and Jeremy Niven of the University of Cambridge examined the brain size of a broad range of organisms, ranging from insects to vertebrates. They also analyzed the complexity of behaviors, social structures and mental processes of the organisms.

The scientists said they concluded animals with bigger brains are not necessarily more intelligent.
