Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental condition that includes a group of symptoms, such as inattentiveness, hyperactivity, and impulsiveness. These symptoms can range in a continuum from mild to severe. 

Symptoms of ADHD tend to be first noticed at an early age and may become more noticeable when a child's circumstances change, such as when they start school. Most cases are diagnosed in children between the ages of 6 and 12. The symptoms of ADHD usually improve with age, but many adults who are diagnosed with the condition at a young age will continue to experience problems in adulthood. It is also very common that many children with ADHD were misdiagnosed, or simply undiagnosed, and obtained a diagnosis of the condition later in adulthood.

Common symptoms include short attention span or being easily distracted, restlessness, constant fidgeting or over-activity, and being impulsive. People with ADHD may find it difficult to regulate intense emotional experiences, often resulting in symptoms of anxiety, depression, and sleep problems.

 CBT, when adapted for the needs of the neurodivergent brain, can help individuals with ADHD, and through tailored strategies and techniques alleviate distress and related symptoms.
