How does ADHD affect the frontal lobe?

Is ADHD frontal lobe damage?

Studies have found that ADHD is associated with weaker function and structure of prefrontal cortex (PFC) circuits, especially in the right hemisphere. The prefrontal association cortex plays a crucial role in regulating attention, behavior, and emotion, with the right hemisphere specialized for behavioral inhibition.

Do people with ADHD have a smaller frontal lobe?

In simple terms, the frontal lobe is the part of the brain that helps you do work and complete tasks. Research has found that this part of the brain is smaller in people with ADHD. However, in some cases, this is a matter of delayed development, and the frontal lobe in people with ADHD grows to a normal size later.

What happens in the brain of someone with ADHD?

Brain development is also slower in people with ADHD. The neural pathways don’t connect and mature at the same rate, making it harder to pay attention and focus. This can impair executive function, which handles organization and routine tasks. ADHD impacts brain chemistry, too.

Does ADHD affect the hippocampus?

The enlarged hippocampus in children and adolescents with ADHD may represent a compensatory response to the presence of disturbances in the perception of time, temporal processing (eg, delay aversion), and stimulus seeking associated with ADHD.

Are ADHD brains smarter?

A popular misconception is that all children with attention deficit hyperactivity disorder (ADHD) are naturally smarter and have a higher IQ than children without ADHD. However, there is no correlation between this condition and intelligence.

Can you see ADHD on a brain scan?

Unfortunately, but unequivocally, no. No brain imaging modality — MRI, SPECT scan, T.O.V.A, or other — can accurately diagnose attention deficit hyperactivity disorder (ADHD or ADD).

Is ADHD neurological or psychological?
