Can a neurologist help children with ADHD?
ADHD is most commonly, due to an deficiency in dopaminergic activity in the prefrontal cortex, which leads to more impulsivity, difficulty staying still (inhibiting movement), and diffculty maintaining focus or concentrating.
The most common reason for this is due to mutations (variations) in the dopamine receptor genes, which lead to reduced binding affinities for dopamine (dopamine can't bind as well to the existing dopamine receptors, leading to reduced dopaminergic activity in the brain).
That is why dopaminergic stimulants are most often used to treat ADHD, as it is a neurochemical disorder.
As such, a neurologist or psychiatrist can administer medication or help with alternative therapies to help treat the disorder.
