Alpha brain rhythms are associated with concentration and focus. Low alpha wave activity is present in a range of mental disorders such as Attention Deficit Hyperactivity Disorder. As we age, our peak alpha frequency and overall power also shifts down, making it harder for us to concentrate.
Conversely, higher alpha peak frequencies and greater alpha wave power is associated with better attention and focus. Experiments show that people with high natural alpha peak frequencies can better distinguish visual stimuli which occur closely together – so if you’re a gamer, you are at your best when your brain is operating at high alpha frequencies.
