There are three types of ADHD, depending on the main difficulties the person is experiencing.
1. Predominantly inattentive type
The person has symptoms of inattention, such as difficulty staying focused, forgetfulness, and poor organisation skills.
2. Predominantly hyperactive/impulsive
Hyperactivity symptoms include excessive movement such as fidgeting, excessive energy, inability to still, interrupting others, and difficulty waiting their turn. Impulsivity refers to decisions or actions taken without thinking through the consequences. A person with this type of ADHD may have fewer symptoms of inattention.
3. Combined presentation
A combination of both types. For example, a person may struggle with staying focused, forgetfulness, poor organisation skills, restlessness, interrupting others, and difficulty waiting their turn.
