This article discussed ADHD. Attention-deficit hyperactivity disorder is a behavioral disorder that develops during childhood and can be characterized by a short attention span, hyperactivity, and little to no impulse control. ADHD runs within families, the genes a person inherits from their parents play a huge role. Some with the disorder, have a hard time with school, work, and relationships with others, due to the fact that the behaviors are severe enough to interfere and cause a lack of attention. ADHD may be caused by a rare gene mutation, a mutation within a single gene is enough to trigger this disorder. Many people in my family have ADHD and it is interesting to see first hand how it may affect their day to day lives and how they do things differently than others, not being able to pay attention for long periods of time or often being forgetful.
