Understanding ADHD
What is ADHD?
Attention-Deficit/Hyperactivity Disorder is a neurodevelopmental condition affecting approximately 5% of children and 2.5% of adults worldwide. It is characterized by persistent patterns of inattention, hyperactivity, and impulsivity.
The DSM-5 recognizes three presentations:
- Predominantly Inattentive -- difficulty sustaining focus, following through, and organizing
- Predominantly Hyperactive-Impulsive -- fidgeting, talking, interrupting, restlessness
- Combined -- features of both inattention and hyperactivity-impulsivity
When to Seek Professional Help
Consider seeking a professional evaluation if you experience:
- Persistent difficulties with attention, focus, or organization
- Problems completing tasks or frequently making careless mistakes
- Restlessness, excessive energy, or inability to sit still
- Impulsive behavior that causes problems in relationships or work
Early identification and treatment can significantly improve outcomes.
