CLEVELAND -- New guidelines from the American Academy of Neurology now state an athlete with a suspected concussion should be immediately removed from play and not allowed to return to the game until they are evaluated by a professional.

Even then, they shouldn't play again until all symptoms are gone.High School and younger athletes should be managed more carefully because their recovery time is longer.

Concussion symptoms include headache, dizziness, trouble with memory or sleep, and changes in reaction time or balance.

Experts say football, rugby and hockey cause the most concussions in male athletes.For females, it's soccer and basketball.

The first 10 days post-concussion has the greatest risk for suffering a repeat concussion and the second one could be life altering.
