Memory Loss
	It’s normal to have momentary memory lapses, but some people have trouble on a regular basis. Persistent memory loss is the hallmark of mild cognitive impairment. About 12% to 15% of people over 65 with this problem per year will go on to develop Alzheimer’s. That’s compared to older people with normal memory that develop Alzheimer's at a rate of 1-percent per year. Researchers use a variety of tools to find the best way to diagnose mild cognitive impairment--like memory tests, which evaluate recall, or short term memory. Blood tests check for known genetic markers and a protein that may be a valid predictor. MRI brain scans measure a memory structure known as the hippocampus. Researchers have also identified a measurable brain chemical associated with dementia. Research is currently underway to see what treatments might delay memory loss. Vitamin E, the drugs Aracept and Exelon, estrogen, non-steroidal anti-inflammatory drugs, and even the supplement ginko bilboa are all being studied.
	If a patient gets a diagnosis of mild cognitive impairment what can they do about it? The best thing to do is be regularly monitored by a physician. The doctor can also help make sure there’s not another reason for the memory loss such as a medical condition or even depression that can impair memory. It’s important to continue to be active and engaged.
