Brain-training exercises and games stimulate and improve your ability to remember, pay attention, process information quickly and creatively navigate daily life. Just as using muscle build muscles, using synapses builds synapses. Scientists call this ability of the brain to change and grow plasticity. A body builder doesn’t do the same exercise or follow the same routine daily. To build muscle, change of routine, repetition is required. The change causes discomfort and sometimes even pain. Brain must be subjected to new learning, new activities and new exercises on a regular basis.
