How to determine if a child has attention deficit hyperactivity disorder (ADHD)

The diagnosis of attention deficit hyperactivity disorder (ADHD) in children is typically based on a series of core symptoms and behavioral characteristics. 1. Inattention is the primary symptom of ADHD. Children exhibit difficulty concentrating in various settings and are easily distracted by external stimuli. 2. Hyperactivity is another prominent feature. Affected children often cannot remain seated and appear excessively active, whether during study or play. 3. Emotional instability and impulsive behaviors are also common. These children tend to be irritable and impulsive, with difficulty regulating their emotions. In making a diagnosis, clinicians must also consider the duration of symptoms. ADHD usually begins before the age of 7 and persists for at least 6 months. Additionally, it is important to assess whether these symptoms significantly impair the child's social functioning, such as academic performance and interpersonal relationships.
