Over the past several decades a growing number of scientific studies have shown that neuro-developmental disorders – as diverse as they may seem – may in fact share a similar common neurological challenge. They are not distinct disorders or diseases but are rather part of a spectrum of disorders.
Many of these disorders show high co-morbidity rate with other disorders along the spectrum. Meaning one person may have multiple diagnoses within the spectrum. Oppositional defiant disorder, Conduct Disorder, Anxiety Disorder, Obsessive Compulsive Disorder, and Attention Deficit Hyperactivity Disorder all have high co-morbidity rates. This suggests that rather than each of these disorders being separate and distinct, they are part of a spectrum of disorders within the developmental delay realm. By addressing the developmental delay through a variety of means and approaches this can address aspects of this developmental delay in the individual.
