Forgetting where you parked your car can be a funny story when you're in your 20s, frustrating in your 40s, but downright scary in your 60s when the threat of Alzheimer's and dementia is starting to loom large. The good news is that science is starting to unravel the mystery of why some people get the disorder and some don't. Here are 2 easy things that you can do right now to reduce your risk of developing dementia as you age.

1.) Buy A Game System

Invest in a handheld video game system (or at least a smartphone) that you can use to download games. Numerous studies indicate that staying mentally active - through reading, writing, and (gasp!) video games - can prevent or delay memory loss.

While some studies have focused on specially designed video games that target an individual's attention span, motor control, and memory - other studies support the idea that video games in general exercise the brain and keep it healthy longer. Puzzles and strategy games, in particular, are highly recommended for mental acuity.

Don't care for Sudoku or regular crossword puzzles? No problem! There are plenty of other video games, word games, logic problems and other puzzlers out there that you can use.

2.) Use A Supplement

Never start a supplement or vitamin regimen without talking to your doctor first. You want to make sure that any other health conditions that you have or medications that you take won't be adversely affected. That being said, talk to your doctor now about adding either Vitamin E or NADH supplement to your diet.

A 2013 study showed that Vitamin E supplements of 2000 IU daily slowed the functional decline of patients who were already diagnosed with Alzheimers or dementia. Vitamin E is an antioxidant that prevents free radicals from damaging the cells in the body. Free radicals are thought to play a strong role in aging because they damage healthy cells in your body. Antioxidants like Vitamin E, however, act as a barrier to protect those cells, ultimately preventing age-related disorders like dementia.

NADH is short for "nicotinamide adenine dinucleotide plus hydrogen," which occurs naturally in the body. It's a coenzyme that triggers other important chemical reactions in the body, including the production of cellular energy in the body. It's also been shown to help trigger the production of dopamine, a neurotransmitter in the body that's responsible for both alleviating depression and keeping the central nervous system functioning properly.

Oral supplements of 10-15 mg per day of NADH have been used to improve general mental functioning, staving off dementia. However, because of its wide-ranging impact on the central nervous system and brain function, NADH is also being looked at to treat or prevent Parkinson's disease, chronic fatigue syndrome, and fibromyalgia. Contact a company like ENADH to learn more about NADH's benefits.

Research is increasingly indicating that old age doesn't have to include dementia. While the exact "anti-dementia formula" isn't yet known, there's growing support for the idea that what you do now can drastically alter your likelihood of developing the disorder as you age.
