Attention deficit hyperactivity disorder (ADHD) is a chronic condition that affects a person’s ability to control thoughts, actions, and emotions. Common symptoms include an inability to focus, organizational difficulties, hyperactivity, and challenges managing behavior and focusing on instructions. ADHD is one of the most common neurodevelopmental conditions in children, and it continues to affect people who have it through adulthood. Since there is no cure, treatment typically aims at improving core functional symptoms.

What is the difference between ADHD and ADD?
ADD (attention deficit disorder) was a term once used to describe people who had trouble with attention and focus without being hyperactive. The term ADHD covers a wider range of symptoms and is divided into three types: inattentive, hyperactive-impulsive, and combined (the most common).
What causes ADHD?
The exact cause remains unknown, but it may be linked to a combination of genetic and environmental factors. It could also be associated with developmental issues in the nervous system, while other risk factors include premature birth, exposure to environmental toxins such as lead, and maternal drug and alcohol use.
