Attention Deficit Hyperactivity Disorder, or ADHD, causes problems with physical activity levels, focusing on family and control of impulses. Even though some people prefer to believe that men and women who are overly active or cannot focus on family have behavioral issues that can be corrected with good discipline, studies show that ADHD is a real condition, possibly with genetic or environmental causes. The Center for Disease Control recognizes ADHD is one of the most common neurobehavioral disorders that are diagnosed in both adults and children. Though many adults often have difficulties sitting still or focusing on tasks, those with ADHD can lead to progressively more serious problems at work and at home. Not all men and women with ADHD have the same degree of physical activity. Some may have a low degree of activity, while others may be highly active. Symptoms include chronic daydreaming, fidgeting, constant motion, inability to listen, inability to sit quietly, problems taking turns, speaking out of turn and difficulty paying attention. Researchers believe ADHD may have a strong genetic component because of their work with twins. Other proposed causes may be exposure to lead, alcohol and tobacco use during pregnancy, low birth weight, premature delivery and brain injury. No research concludes that poverty, family problems, and too much television or consuming large amounts of sugar causes ADHD, though these factors may exacerbate symptoms. These are serious problems that can seriously affect your marriage. If you see any of these symptoms in your spouse or partner you need to pick up a copy of this book : The Effect ADHD Has On Marriage by Terence A.
