ADHD, or Attention Deficit Hyperactivity Disorder, is a neurodevelopmental disorder that affects individuals of all ages. It is characterized by a persistent pattern of inattention, impulsivity, and hyperactivity that interferes with daily functioning and activities. Symptoms may include difficulty with concentration, forgetfulness, impulsivity, restlessness, and poor time management. While the exact causes of ADHD are unknown, research suggests that genetics, brain function, and environmental factors may contribute. However, with proper diagnosis and treatment, including medication, therapy, and lifestyle changes, individuals with ADHD can successfully manage their symptoms and lead fulfilling lives.
