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.

“Our sons were both diagnosed with ADHD by kindergarten. More than just dealing with the disciplinary and academic issues at school, my husband and I struggled to maintain a productive and nurturing household with the kids having regular meltdowns and outbursts. Our ability to connect with them became compromised. We were at our wits’ end considering medications and home school. We agonized over the long-term repercussions of both of those choices. We turned inward and analyzed our habits and routines. One thing we noticed with both the boys was that a strict routine in the mornings and in the evenings seemed to help and that physical interventions (rather than reasoning or time-outs) worked best to correct behavioral problems – getting them outside, running them around, engaging them in a physical activity. There were particularly frenetic times when we would take them to the track at the local middle school and have them run laps. The more we intervened in that way, the fewer the outbursts and behavior issues and ironically, the better they’d sleep; but we were concerned that they would start seeing exercise as a punishment and decided to take a different approach.

The nervous system and its communication with peripheral organs is under the continuous dynamic influence of hormones, neuroactive steroids, and neurotransmitters. This is why the underlying pathology of mood disorders can often be varied and complex.

The hormonal piece is critical to our understanding of the imbalances when it comes to the complete neurotransmitter assessment. Hormones regulate key processes pertaining to neurotransmitter biosynthesis, signaling, and degradation. It is important to recognize that disturbances in the relationships between hormones and neurotransmitters can shape normal physiology toward a maladaptive state leading to suboptimal psychological wellbeing.

ZRT's senior research scientist Dr. Kate Placzek presented a webinar about the neurotransmitter testing ZRT began offering last year.

Neurotransmitter testing is a natural progression of the wellness testing options that ZRT has developed and offered over the years, and in some ways encompasses many aspects of the testing in other areas such as steroid hormone and metabolite testing, adrenal and thyroid health assessment, cardio-metabolic parameters, and heavy metals.

She addresses these questions that are commonly asked by health care providers who call in to enquire about this testing.
