Several brain neuroimaging studies have detected that there are several specific brain regions in children with ADHD. Alterations have been described in:
How does ADHD affect?
The studies carried out indicate that ADHD causes problems in the regulatory circuits that communicate two brain areas: the prefrontal cortex and the basal ganglia. These areas communicate through dopamine and norepinephrine. By having a deficient release of these neurotransmitters and a high level of their reuptake, altering neurotransmission, affecting attention, alertness, working memory, and executive control.
The decrease in synaptic metabolism of neurotransmitters produces the following consequences:
Decreases attention
Decreased ability to start and continue activities.
Impairs working memory (or short-term memory)
It makes it difficult to neutralize irrelevant stimuli.
Difficulty in the ability to block inappropriate responses
Difficulty planning complex activities.
makes organization difficult
Increase physical activity
Increases impulsivity
