Narrator: TThis is Science Today. Although Alzheimer's Disease is the most common cause of dementia, there are several health problems which may affect memory as a secondary change. Jay Luxenberg, an associate clinical professor at the University of California, San Francisco says in these cases, memory loss may improve with proper intervention.
Luxenberg: For example, people with high blood pressure have a faster decline in their memory if they don't treat their blood pressure well. We also know that people who have significant hearing impairment or visual impairment have a greater rate of decline in their memory and we always advocate that somebody who has a reversible cause of a sensory impairment, for example a hearing impairment that can be improved with a hearing aid, they should go ahead and do that.
Narrator: Depression in elderly patients has also been linked to memory loss.
Luxenberg: When it's not treated, their memory will appear impaired and that impairment can improve dramatically when you treat the depression.
