Well first you must ask if ADHD exists, or if it is appropriately defined. Secondly, there are treatment options such as ritalin
(which is often abused, so adults should monitor administration). Some of my friends say ritalin only made them worse in the long run. Either way a treatment is not a cure.
ADHD may just be a new developemental stage in humanity's mental evolution helping us deal with a fast-paced world and multi-dimensional society. Psychiatrist
can help return you to the "norm", but they can't justify that its the right thing for everyone.
More Natural treatments include the following from what I've heard (these might seem self-evident):
-Classical Music while studying
-Giving up caffiene, nicotine
, and high sugar content foods
-Getting More Sleep
-Giving up Television (this may be more effective than many people realize), occasional movies are okay
-Montessouri or Hands on education
-Avoiding Florecent or Neon Lighting
