ADHD, or Attention-Deficit/Hyperactivity Disorder, is a neurodevelopmental condition that affects both children and adults. It is characterized by persistent patterns of inattention, impulsivity, and hyperactivity that can impact various aspects of daily life, including school, work, and relationships. ADHD's exact cause is not fully understood but is believed to involve a combination of genetic, neurological, and environmental factors. Treatment typically involves a multifaceted approach, which may include behavioral therapy, medication, and lifestyle adjustments, aimed at helping individuals manage their symptoms and enhance their overall functioning.
