ADHD is categorized as a mental health condition with symptoms such as inattentiveness, impulsivity, and hyperactivity. The symptoms differ from person to person. ADHD was formerly called ADD, or Attention Deficit Disorder. Both children and adults can have ADHD, but the symptoms always begin in childhood. People with ADHD may have trouble managing time, being organized, setting goals, making friends and holding down a job. A Speech-Language Pathologist can help.
