The Link between Estradiol Deficiency and Attention Deficit Hyperactivity Disorder (ADHD)
ADHD impacts millions of women and girls and yet many go undiagnosed or misdiagnosed for most of their lives.1 It’s a disorder that manifests in childhood, but has never been easily recognized in girls. For a lot of years, ADHD was thought to be a boys’ phenomenon. Now we know better.
ADHD simply displays differently in girls. They don’t fit the stereotype of this disorder and their symptoms are more subtle. Where boys seem to be “bouncing off walls” or acting out in other ways, girls tend to turn inward and suffer from self-esteem issues, self-blame, major depressions, anxiety and eating disorders.
Girls and women are commonly misdiagnosed as bipolar or having a primary depressive disorder rather than ADHD. If they do get the appropriate diagnosis, they are generally treated with the same drugs given to young boys, which don’t address the complexities seen in females with the condition.
The Hormone Connection with ADHD
Steroid hormones are not just sex hormones. They play an important role throughout the body and especially in the brain. Estradiol in particular exerts a significant and complex impact on brain chemistry. This hormone has been shown to be neuroprotective2 and has a substantial influence on memory, cognition and brain plasticity, thus helping the brain perform better and faster. Estradiol does this by increasing vital concentrations of serotonin, dopamine, and other neurotransmitters significant to healthy brain performance.
Conversely, when hormones are fluctuating or deficient, neurotransmitters cannot be manufactured in the quantities needed for normal brain function. Evidence shows that the brains of those with ADHD are deficient in these neurotransmitters. Treatment usually involves medications that target these deficiencies by stimulating the production of serotonin and dopamine. What is often left out of that equation for girls and women is the impact fluctuating hormones have on ADHD.3
Insufficient Estradiol Levels Worsen ADHD in Women
Scientific research continues to explore the vital role estradiol plays in the brain.4,5 Several decades ago, it was noted that there was a possible link between hormones and ADHD in women (Hussey 1990). Low estradiol states—such as those occurring during a woman’s monthly cycle, post pregnancy, or during perimenopause and menopause—seem to exacerbate ADHD symptoms.6 It consistently appears that girls with ADHD experience increasingly severe problems at the onset of puberty, a time when hormone levels fluctuate between highs and lows. Women have likewise reported that the arrival of perimenopause caused their ADHD symptoms to worsen while at the same time lessening the effectiveness of their ADHD medications. Physicians frequently respond to these women by upping their stimulant medication, which does little to help.
Support for Women with ADHD
What does seem to help women with ADHD is a holistic treatment approach that combines various strategies. These can include ADHD medications; behavioral techniques—such as cognitive behavioral therapy and coaching; diet; exercise; and last, but not least, hormone replacement therapy.
HRT, especially properly administered bioidentical HRT, has been shown to ease some symptoms of ADHD for perimenopausal and menopausal women with this disorder. Restoring physiologic levels of testosterone and estradiol enables these hormones to combine efforts in the brain and increase vital serotonin and dopamine levels. This beneficial replenishing of key hormones can provide relief from depression, anxiety and other disabling symptoms related to the neurotransmitter deficiencies of ADHD.
Some Common Signs of Adult ADHD
Women are often not diagnosed with ADHD until their mid-30s or even into their 40s or 50s when hormone insufficiencies cause symptoms to worsen. If you have had at least 5 of the symptoms listed below during puberty or sometime prior to the onset of perimenopause, you may want to get tested for ADHD. And while you’re at it, contact a bioidentical hormone replacement expert who can measure your hormone levels to determine if you have hormone deficiencies that also need treatment.
