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.

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

Everything we do, feel, think – it all starts with the brain. A balanced, healthy brain helps lay the essential foundation for optimal wellbeing. A small but significant aspect of brain health is regulated by a specific class of steroid molecules called neurosteroids. 

That the brain is a steroidogenic organ is widely accepted, and neurosteroids are woven into its very fabric. In fact, the term “neurosteroid” refers to cholesterol-derived steroid compounds that play critical roles in the nervous system - its development, maintenance and survival. “Neurosteroids: of the nervous system, by the nervous system, for the nervous system” as Baulieu said a decade and a half following the remarkable discovery of the very first neurosteroid - DHEA-S [1] [2]

We're in a new year now and it seems like everyone's weighing in on the 5 or 10 or 20 things you and I should be doing to improve our health and wellness this year.

If you want to improve brain health, you need to make sure it gets enough oxygen, nutrition, and anti-oxidant support so that’s the unifying theme. I have a feeling if everyone did these, in 20 years we’d have fewer cases of psychological dysfunction and of neurodegenerative disease.
