What body systems does ADHD affect?
Three types of ADHD exist. Predominately inattentive presentation makes organizing and paying attention difficult. Predominately hyperactive-impulsive presentation is marked by the inability to sit still and impulsivity. Those with combined presentation have symptoms from both categories. Diagnosis of ADHD is a multistage process that includes a medical exam to rule out other causes. Those with the disorder often have accompanying conditions such as anxiety.
