Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with daily life. Symptoms often begin in childhood and can continue into adulthood. Examples include difficulty sustaining attention, excessive fidgeting, talking excessively, interrupting others, and acting without considering consequences.
Causes and Risk Factors of ADHD Symptoms
The exact cause is unknown, but genetic and neurological factors play a major role. Risk factors include family history of ADHD, premature birth or low birth weight, prenatal exposure to alcohol, tobacco, or drugs, and early head injuries. Environmental exposures, such as lead, may also contribute.
When to Seek Medical Care
Consider professional evaluation if inattention or hyperactive behaviors persist for six months or longer, occur in more than one setting (home, school, or work), and significantly disrupt daily activities. Early diagnosis and treatment can improve school performance, workplace functioning, and relationships.
