Attention Deficit Hyperactivity disorder (ADHD) is a neurodevelopmental disorder that has a genetic basis. It is associated with the specific development of the central nervous system, affecting both the biochemistry of the brain and its structure.
Symptoms of ADHD are subject to change and can be aimed at minimizing them, but the deficiency at the biological level is objective and permanent over time. Too much screen time, poor lifestyle hygiene, and poor nutrition only make the symptoms of ADHD worse, but they are not the source of it.
People with ADHD have impaired dopaminergic, noradrenergic, and serotonergic neurotransmission. The above neurotransmitters are responsible for:
-
short-term memory
-
the ability to remember acquired knowledge (science)
-
impulsivity
-
body arousal / drive, increased need for movement
-
motivation
in addition, the cerebral cortex of people with ADHD develops unevenly. Studies indicate less activity of a structure such as the prefrontal cortex, which is responsible for:
1. Planning, managing time, organizing, learning from mistakes, anticipating the consequences of your actions
2. Inhibition of impulses (including aggressive ones), control of behavior, behavior compatible with social norms
