Adult attention-deficit disorder
Adult attention deficit disorder (AADD) refers to the psychiatric condition currently known as attention-deficit hyperactivity disorder (ADHD) (also known as attention deficit disorder (ADD)) when it occurs in adulthood. Although the exact prevalence in adults is unknown, epidemiologic studies thus far reveal that the condition, marked by inattentiveness, difficulty getting work done, procrastination, or organization problems, probably exists in about 2-4% of adults. Adults' symptoms may manifest themselves differently from children's. Often the most prominent characteristic in ADHD adults is difficulty with executive functioning, which is the brain activity that oversees the ability to monitor a person's own behavior by planning and organizing. Other symptoms observed in adults include inattention, impulsivity, and restlessness as well as frequently accompanying behavioral, learning, and emotional problems. Adults with hyperactive-impulsive symptoms feel restless and constantly "on the go" as they try to do multiple tasks at once. They are often perceived as not thinking before they act or speak.
