Alzheimer's disease may look and act differently in men and women, new research suggests.

An emerging field known as gender-specific medicine has shown pronounced differences among the sexes in heart disease and other conditions. These latest findings -- if confirmed by further research -- may have significant implications for diagnosing and treating Alzheimer's.

Women also lost more gray matter in their brains in the year before their diagnosis. However, men seemed to have more problems with their thinking ability when diagnosed with Alzheimer's than their female counterparts did.

The study was presented at the Radiological Society of North America annual meeting, in Chicago.
