Alzheimer's disease affects roughly 5.4 million Americans, and the progressive illness slowly eats away at the cognitive abilities of those who it affects, according to the Alzheimer's Association. Scientists are continually working to better understand dementia, including how to prevent it and how to treat it.

Since dementia affects an individual's ability to comprehend spacial relationships, this could increase the risk of falling. A personal emergency response system can provide security that a medical alert will get help if an older adult is injured.

New research that was conducted by scientists at the University of Gothenburg's Institute for Neuroscience and Physiology found that a diet that includes lots of fish may reduce the risk of developing dementia. This could be due to the high content of omega-3 fatty acids in certain types of fish, such as salmon, tuna and halibut. The researchers also noted that the high content of saturated fats in meat and dairy products can increase the risk.

"It seems pretty clear that if you're picking a diet to prevent Alzheimer's disease with the knowledge we have today, you would pick a diet rich in fish, fruits and vegetables and low in [saturated] fat," William Thies, the scientific director of the Alzheimer's Association, told WebMD.
