Is there any definitive solution to cure adhd on its way ?

Unlikely to happen: Add and adhd are disorders of attention and motor activity related to the pattern of neurologic development. Treatments provide temporary benefit to those affected, by altering some of the brains regulatory centers. About 1/3 kids will grow out of the problems as they mature, 1/3 will decide to self compensate but avoid medication and 1/3 have the issue as adults.You can't rewire the human brain.
