Children here in the US are being diagnosed with ADHD at quite the alarming rate. Many believe this is due to drug pushing and so forth, but more recent research is pointing in a whole new direction.
An ever-growing number of researchers are proposing that this could simply be a sleep disorder mimicking ADHD that is getting diagnosed as ADHD or something of the sort. Several studies actually show that there is a strong link between ADHD and sleep length and quality in general.
This leads to the question: Could ADHD itself be a sleep disorder? Data presented just this month at the European College of Neuropsychopharmacology Conference in Paris seems to suggest so. Researchers looked at people’s circadian rhythms (the natural cycle of how they sleep and wake). This showed that subjects who had ADHD experienced a melatonin rise 1.5 hours later in the night than those without ADHD. This meaning they do fall asleep but get less sleep overall.
According to Sadra Kooji from the Vrije Universiteit Medical Centre in Amsterdam when night rhythm is disturbed so are temperatures, movements, and even the timing of meals. This leads to a change in behavior. Sleep disorders are quite common among children and some research actually shows they may be overall around 40 percent.
With research pointing to about 75 percent of people with ADHD having sleep disturbances and increased symptoms with less sleep, the signs are all there.
