Epigenetics & Psychiatry

The field of epigenetics has far-reaching implications for psychiatry. As acquired epigenetic alterations can be transferred to the next generations, what scientists used to label as an inherited psychiatric disease may in fact be the result of epigenetic changes in a family’s shared environment.

Many psychiatric diseases are consistent with the theory of epigenetic dysregulation because of their fluctuating nature and disease course. Single gene and whole genome epigenetic analyses have shown atypical epigenetic markers in the blood and brain of individuals with psychiatric diseases including abnormalities in DNA methylation, histone modifications and microRNA expression.

This is part one of Dr. Greenblatt's Nutritional Lithium series. Part two can be found here.

As far as cosmologists can tell, there were only three elements present when the universe was first formed some 13.8 billion years ago: hydrogen, helium, and lithium.

As one of the three original elements, lithium is found throughout our atmosphere. The sun, stars, and meteorites burn brightly with the gleam of this highly reactive element. On earth, lithium remains a major mineral component of granite rock, and also lingers in significant amounts in sea water, mineral springs, and soils. 

Lithium has also found its way into our cell phones, electric cars, and holiday fireworks. Every organ and tissue in the human body contains the mineral lithium, with particular importance in health, specifically brain health.

In part 1 of this series, we discussed the importance of correcting trace mineral imbalances of copper and zinc to reduce behavioral symptoms and improve medication efficiency in children with ADHD. There is another nutrient that should be considered by all healthcare professionals, parents, and those struggling with ADHD: magnesium. Magnesium is a macromineral required for hundreds of the body's biochemical reactions including protein synthesis, muscle and nerve function, blood glucose control, bone development, DNA synthesis, and glutathione synthesis.

What if there was a safe, effective, inexpensive, and simple way to help treat one of the most common neurodevelopmental disorders of childhood?

Health care professionals often overlook nutrients; yet imbalances in many minerals are frequently seen in medical disorders including ADHD. Fortunately, replenishing nutrients with an integrative treatment plan has proven to be an effective treatment for the symptoms of ADHD.

In this two-part series, we will evaluate mineral deficiencies in zinc and magnesium, excess copper, and their relationship with neuropsychiatric symptoms.
