Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — dopamine

Dr. Tracy Tranchitella explores why ADHD in women is so often missed — from the quiet, dreamy girl in the classroom to the menopausal woman struggling with focus and memory — and how declining estrogen affects dopamine, executive function, and cognitive health across a woman's lifespan.

Neurotransmitter imbalances can affect mood, behaviour, sleep, and focus in both adults and children. Discover how urine-based neurotransmitter testing can help identify the root cause of symptoms like anxiety, depression, and ADHD — and guide personalised treatment.

  Important limitation: The original article below contains broad diagnostic and treatment claims that should not be treated as clinical guidance. Urinary neurotransmitter measurements do not reveal brain neurotransmitter concentrations, diagnose psychiatric or neurological disorders, select antidepressants or establish that testing improves health outcomes. They are not screening tests for Parkinson’s disease or Alzheimer’s disease and do not prevent their progression. Persistent symptoms require appropriate clinical assessment. Neurotransmitters are chemical messengers in the brain that play a crucial role in regulating our mood, emotions, behaviour, and overall mental health. Imbalances in neurotransmitters have been linked to a range of psychiatric...

The contraceptive pill is one of the most widely used medications in the world — but its effects on mood, brain chemistry and hormone balance are still poorly understood. This article explores how synthetic hormones disrupt oestrogen, progesterone, cortisol and neurotransmitters, and why some women are far more vulnerable to depression and anxiety as a result.

Perimenopause is far more than a reproductive transition — it is fundamentally neurological. As oestradiol declines, the brain’s bioenergetic system becomes compromised, neurotransmitter balance shifts, and the thermoneutral zone narrows, giving rise to hot flashes, mood instability, memory changes and sleep disruption. This article explores the neuroscience behind the menopausal transition and why hormone replacement therapy — timed correctly — may be the most effective intervention.
