I've recently been developing a theory as to the possible cause of ADD/ADHD which also extends itself into Bipolar Disorder. According to my theory, I believe that ADD/ADHD and Bipolar Disorder are in fact the same disorder only at perhaps different stages. The root cause of the disorders stems from the deep repression of emotions. Why might an adult with repressed emotions not share symptoms with one who has been diagnosed with ADD/ADHD at an early age? The answer is the age at which the emotions began to be repressed. A child who has repressed his or her emotions differs from an adult who has repressed his or her emotions because the child's brain is still in development. I speculate that the emotions being repressed in the child causes a change in the way their brain functions, hence causing the symptoms seen as ADD/ADHD. I personally do not believe ADD/ADHD are genetic disorders. I believe them to be developed disorders, caused by the repression of emotions. What IS genetic, at least what I think, is the hyperactivity one finds in a child. It seems to me that those affected by ADD/ADHD are generally either born hyper or naturally emotionally sensitive. Perhaps that is a gross generalization but the notion still stands. Anyone else feel that repressed emotions may play a key role in ADD/ADHD?
