Is Attention Deficit Hyperactivity Disorder A Real Disorder?

 

Beyond our own observations and experiences, Neuroimaging results (MRI, PET, SPECT, etc.) have found differences in brain development and/or brain activity in individuals with Attention Deficit Hyperactivity Disorder (ADHD) in several areas of the brain, such as the cerebral cortex (frontal, parietal, and temporal lobes), basal ganglia, cerebellum, and other areas.

 

Frontal Lobe decisions & planning

Parietal Lobe processing sensory information from the body

Temporal Lobememory & emotion

Basal Ganglia movement, coordination, cognition, & memory

Cerebellumattention, fine movement coordination, & balance

 

In the field of Molecular Genetics, several gene associations have been identified, such as the 7-Repeat Allele (7R) of the Dopamine Receptor D4 Gene (DRD4) located on Chromosome 11; an allele is an alternative form, or variant, of the D4 Gene. Some studies have shown a strong correlations with some genes, while other studies have shown a weaker significant association.

 

Besides confirming the existence of ADHD, evidence increases our knowledge about the disorder, giving us a better understanding that can lead to more solutions. Because of the myriad of ongoing research in the ADHD field, it is important that individuals find therapists who remain competent by staying current with modern best practices and treatment modalities.
