If you want to maintain your mental acuity as you get older, this research-based driving game was designed with you in mind. If you are already experiencing cognitive impairment due to a head injury, ADHD, stroke, or age related cognitive decline, these exercises can help your brain build new connections and renew your brainpower. Developed by a neuropsychologist, SmartDriver provides you with 45 different tracks ranging from easy to challenging to help you exercise your brain and stay mentally flexible.

Combining the Neurosky MindWave headset and the optional "BrainPower System", you can learn to develop "C.H.A.R.M.", a Calm Happy Alert Relaxed Mental state, while you exercise your brain.
