|ADHD Sleep Problems caused by Melatonin Deficiency|
The Swedish study looked at the genes that regulate Melatonin in over 300 individuals of which 100 had a diagnosis of ADHD. They found significant changes in the melatonin signaling pathways only in the ADHD patients and not in the controls.
This is the first study that confirms that ADHD sleep problems are not related to medication effects or hyperactivity symptoms but rather are the result of melatonin deficiencies.
Melatonin, according to the authors of this Swedish study, is a "powerful antioxidant and a synchronizer of many physiological processes". It is unknown how much of a role melatonin deficiencies play in the presence of the inattention seen in ADHD Inattentive but it is clear from many other studies that inattention, loss of concentration and loss of focus in people with and without ADHD Inattentive or the other types of ADHD can all be the result of sleep deprivation.
I have noticed improved attention in myself and in my ADHD Inattentive son when we are well rested. It is encouraging that researchers are getting to the bottom of the sleep disturbance issues that are a common problem in people with ADHD.
