Discovery offers promise for treatment of age-related hearing loss

Researchers have discovered that deletion of a specific gene permits the proliferation of new hair cells in the cochlea of the inner ear -- a finding that offers promise for treatment of age-related hearing loss. This type of hearing loss is caused by aging, disease, certain drugs, and the cacophony of modern life. It is the most common cause of hearing loss in older people.

Low carbohydrate diet may prevent Alzheimer's disease

Researchers found that a low carbohydrate diet that reduced total caloric intake by 30% prevented the development of a fundamental feature of Alzheimer's disease (AD) in mice genetically engineered to develop the disease. The diet eliminated amyloid plaque development, which is the underlying pathology in AD.

New tool to detect Alzheimer's early

Doctors have long known that smell is one of the first senses to fail as Alzheimer's begins its slow and incurable progression. Tracking the process whereby a person loses their ability to smell could play a pivotal role in early detection and treatment of Alzheimer's. And now researchers at Columbia have developed a tool that will aid early detection.
