Concussions 

Any hit to the head can result in changes to the balance of your brain frequencies, even if you did not experience a full-blown concussion or were not knocked unconscious.

 

When brain tissue is damaged in any capacity, the brain begins to produce slower frequencies in attempt to heal affected areas. Over time, brain frequencies can become imbalanced and in turn, lead to different physical and psychological outcomes, such as anxiety, hyper-vigilance and depression.
