Facelifts, botox, fillers, and pricey face creams are the go-to solutions for warding off those dreaded signs of aging. But while the emphasis on good skin care is obviously a no-brainer when it comes to remaining youthful, it's not the only thing you should be focusing on.

"We start aging the moment we are born," explains NYC Neuropsychiatrist Maurice Preter, MDNew York City Neuropsychiatrist Maurice Preter, MD. "But aging is just very much as much mental as it is physical, which is why self care is so important." Whether you're aware of it or not, cognitive function can rapidly decline as you get older, making you more forgetful and unable to comprehend things as quickly or as clearly as before.

Luckily, it's easier to fend off the mental signs of aging than you might think. Neurobic exercises, gathered developed by the late author and neurobiologist, Lawrence C. Katz, PhD., are shown to be some of the best ways to build and strengthen your memory. Partaking in these simple exercises could mean all the difference when it comes to keeping your mind sharp, so read on for our science-based tricks to keeping your mind as young as your face!.

Whether you're right-handed or left-handed, using your non-dominant hand to do anything at all feels like a total chore. But according to the book "Keep Your Brain Alive: 83 Neurobic Exercises to Help Prevent Memory Loss and Increase Mental Fitness," by Dr. Katz, switching to your non-dominant hand when doing an everyday task like brushing your teeth or writing notes can be a great workout for your brain.

Here's how it works: When using your non-dominant hand, the network of connections in the brain area that's involved in using that specific hand (which are infrequently used), become activated and strengthened within your brain. These networks are usually ignored when relying on the stronger networks that control your dominant hand, so switching it up from time to time will help engage your mind to make it more agile.

Your daily cup of joe might be giving you more than just an energy boost each morning. A study published in "The Journal of Nutrition" suggests that your early morning caffeine pick-me-up has long-term benefits on your thinking skills and attention span in addition to the temporary mental clarity you receive right after sipping.

In the study, researchers from the National Institute on Aging found that those who drank more caffeine did better on memory tests than those who drank it less often. The brain stimulant not only gives the body a rush of energy, but also improves mental performance -- no matter what your age is.

Who knew that waking up to a new scent could amp up your brain power? While freshly brewed coffee is the usual scent associated with the start of a new day, waking up to a smell that's not linked to your morning routine (like vanilla or citrus scents) will activate new neural pathways in the brain. Wake up and burn a lavender-scented candle, or sip some peppermint tea.

Keeping a journal or diary is not only one of the best ways to detach from digital distractions, but it can also improve concentration and memory skills. The physical action of scribbling down letters on a page (rather than just hitting the exact same keys on a keyboard) activates the part of the brain that develops the learning process, making it easier to comprehend new material.

While keeping a full, complete diary might be a bit time-consuming, using something like the Five Minute Journal, $23, is a great way to get yourself writing while also being superproductive (this particular journal helps you to prioritize tasks for the day while setting individual, short-term goals as well).
