It is more commonly diagnosed among boys than girls, given differences in how the symptoms present. However, this does not mean boys are more likely to have ADHD. Boys tend to present with hyperactivity and other externalizing symptoms, whereas girls tend to have inactivity.
​
There are three main types of ADHD:
· Predominantly inattentive presentation.
· Predominantly hyperactive/impulsive presentation.
· Combined presentation.
ADHD is a protected disability under the Rehabilitation Act of 1973 and the Americans with Disabilities Act (ADA). This means that federal funding institutions cannot discriminate against those with disabilities. Individuals whose symptoms of ADHD cause impairment in the work setting may qualify for reasonable work accommodations under the ADA.
ADHD treatment usually encompasses a combination of therapy and medication intervention.
