ADHD Kids and Moms Have
Shorter Telomeres (or Chromosome Caps)
Children with attention deficit hyperactive disorder — and their mothers — are more likely to have shorter than normal telomere length, a new study finds.
Often described as similar to the hard plastic ends of a shoe string, telomeres “cap” the ends of chromosomes, protecting against the loss of DNA during cell division. Telomere length (at birth) appears to be genetic and was found correlated to the degree of hyperactivity and impulsivity, not inattention.
Previous studies have linked shortened telomere length to conditions such as autism.
According to Dr. Harold Levinson, this study provides several interesting insights. It suggests a maternal hereditary component for only the hyperactivity-impulsivity component of ADHD. It further indicates that the inattention and hyperactivity-impulsivity symptoms of ADHD have different mechanisms and origins.
Current traditionalist theories do not clearly and simply explain how ADHD, its varied symptoms, as well as the overlapping of this disorder with dyslexia, autism and many other comorbid impairments occurs genetically and can be acquired at any age. By contrast, Levinson’s cerebellar theory of ADHD and dyslexia readily accounts for all the characteristics and variations of the above disorders while offering new and better treatment modalities.
