Final answer:
Hypersensitivity in individuals with ADHD is related to neurological differences, specifically dysfunction in the prefrontal cortex and neurotransmission, which makes them more sensitive to stimuli such as clothing, lights, and sound.
Step-by-step explanation:
The cause of hypersensitivity in individuals with Attention Deficit Hyperactivity Disorder (ADHD) is largely due to neurological factors rather than emotional responses to external events like family arguments or being a '“drama queen.”
Research indicates that ADHD is associated with a delay and dysfunction in the development of the prefrontal cortex and disturbances in neurotransmission. This can contribute to a heightened sensitivity to stimuli such as clothing, lights, and sound, which can be overwhelming for someone with ADHD. This is not to be confused with the hypersensitivity seen in allergic reactions, which involve an immune response to harmless substances.
Treatment for ADHD may include behavioral therapies and the prescription of stimulant medications, which help alleviate symptoms by increasing dopamine levels, leading to improved attention and reduced impulsivity.
