ADHD is considered a disorder that involves which types of influences?

ADHD, or Attention-Deficit/Hyperactivity Disorder, is widely recognized as a complex condition influenced by a combination of factors. The correct choice highlights that both genetic and biological factors play a crucial role in the development of ADHD. Research indicates that ADHD often runs in families, suggesting a strong genetic component. Specific genes related to neurotransmitter functions have been identified, indicating biological underpinnings.

Moreover, environmental influences, such as prenatal exposure to tobacco smoke, alcohol, or lead, as well as psychosocial factors during early development, can exacerbate or contribute to the disorder's symptoms. This multifaceted perspective emphasizes the interplay between a person's biological makeup and their environment, making it key to understanding ADHD as a disorder that does not arise from a single source. This understanding is critical for effective interventions and treatment planning, as it acknowledges the holistic nature of ADHD's origins.
