What is attention deficit?

The TDA is the behavioral disorder that is diagnosed in childhood and is estimated to affect 3% to 5% of school-age children, ie around 1.5 million children in Mexico suffering from this condition that is characterized mainly by inattention.
What causes it?
The causes of this disorder are not yet clear, it appears that familial predisposition is also scientific evidence that support the conclusions that the TDA has a biological basis and that children with ADD may have lower levels of the neurotransmitter dopamine in critical regions of the brain. Other studies suggest a decline in activity in some brain areas in which implementation tasks are handled (such as organization, integration, anticipation, attention, etc.)..
