"Our finding suggests that Alzheimer's disease produces broader damage in the brain than previously thought, including damage to areas not usually associated with the disease," said lead author Sarah Madsen, a graduate student working with Paul Thompson, PhD, of the University of California, Los Angeles. "Our finding suggests a gradual progression of brain tissue loss in the caudate nucleus as dementia becomes more severe," said Madsen. "This brain area, which is associated with certain forms of learning and memory as well as motor control, is an important factor to consider when studying Alzheimer's disease and in predicting how the disease will progress," she said.
