The polyvagal idea, launched by Stephen Porges, PhD, in 1995, explains how human adaptive responses are modulated by means of the autonomic nervous system (ANS). This idea challenges the standard idea, which describes the ANS as a functionally antagonistic system with sympathetic (“struggle or flight”) and parasympathetic (“relaxation and digest”) modes, by proposing a 3rd purposeful department.¹ The parasympathetic nervous system, predominantly mediated by the vagus nerve, subdivides within the brainstem into ventral and dorsal vagal tracks. The polyvagal idea postulates that the ventral observe induces the “social engagement system,” as illustrated by means of our means to attach interpersonally throughout occasions of security; then again, the dorsal observe triggers a death-feigning response noticed as dissociating or “freezing” throughout life-threatening conditions.² With this distinction, the polyvagal idea explains how the sympathetic and parasympathetic techniques can elicit a trio of adaptive and hierarchal responses – throughout occasions of security, hazard, and excessive menace.³ 

When experiencing a traumatic occasion, the dorsal vagal observe might change into activated, leading to each the immobilization of a person’s bodily physique processes and their emotional resiliency.² On this state, the power to adapt and in the end restore physiological and emotional homeostasis is inhibited. To remobilize, the person should obtain security cues to disengage the dorsal vagal state and revive ventral vagal tone.³ On this case examine, we study a affected person who exhibited what could also be thought-about a state of dorsal vagal activation resulting from a traumatic expertise. We sought to offer our affected person with the mandatory security cues to defuse her extended state of dorsal vagal activation and information her again to a baseline of social engagement and optimum well being.

Presenting Issues & Historical past 

A 65-year-old feminine introduced to our clinic with a 17-month historical past of extreme day by day migraines, continuously resulting in vertigo and vomiting. The affected person said that her complications inhibited actions of day by day dwelling, leading to a sense of profound isolation and hopelessness, and prompting an unyielding preoccupation with dying. Along with day by day migraines, she reported refractory insomnia, ongoing melancholy and anxiousness, and an intense longing for acidic meals. The affected person had skilled important trauma – sexual assault adopted by intrusive police interrogation – instantly previous to the onset of her power complications. She was taking sumatriptan day by day for migraines, zolpidem as wanted for insomnia, and sertraline day by day for melancholy, all of which have been prescribed by her main care doctor (PCP). 

Scientific Findings 

The affected person introduced with a flat have an effect on, delayed speech, and extreme yawning. She displayed important issue strolling and standing upright. Her conduct was cooperative, although communication was gradual, revealing cognitive delay. The neurological bodily examination elicited no optimistic findings, and neurological and spinal imaging revealed no abnormalities. Her BMI was 19 and screening blood work was regular apart from her HbA1c, which was 5.8%, indicating prediabetes. The questionnaires Basic Nervousness Dysfunction-7 (GAD-7) and Affected person Well being Questionnaire-9 (PHQ-9) revealed average anxiousness and extreme melancholy. 

Therapeutic Interventions 

Our therapy targets included migraine reduction, sleep enchancment, psychological well being help, and blood sugar regulation. We hoped to cut back the affected person’s reliance on sumatriptan for migraines (for which she discovered minimal symptom discount) and zolpidem for insomnia (because it left her incapacitated with mind fog, dizziness, and fatigue). As well as, the affected person’s use of sertraline was resulting in undesirable unwanted side effects, akin to dizziness and intention tremor, and was not successfully managing her signs of melancholy. Lastly, we needed to reverse her prediabetes standing to stop comorbidities. 

Migraine Aid 

Craniosacral remedy (CST) is a mild, hands-on therapy that examines the refined motion of cerebrospinal fluid and offers a hyperlink between the ANS and bodily illnesses.⁵ Throughout CST, the practitioner locates and releases areas of bodily stress, thereby defusing heightened sympathetic or dorsal vagal responses.⁵ On this approach, CST can rebalance a dysregulated nervous system. By means of this strategy, we launched the mandatory security cues to deliver a few extra regulated nervous system response, supporting the muse upon which subsequent therapeutic may happen. 

Analysis has proven a correlation between experiencing trauma and elevated frequency of migraines, resulting from trauma’s means to dysregulate the nervous system.⁶ Beforehand believed to be vascular in origin, migraine complications are actually understood as a dysfunction pertaining to nervous system perform; research point out diminished sympathetic perform amongst migraineurs and elevated susceptibility to migraines amongst folks with irregular nervous system responses.⁷ In regulating the nervous system by means of CST, we sought to lower the frequency of this affected person’s migraines. 

As well as, magnesium deficiencies have been linked to migraine improvement and are believed to be concerned in a number of points of migraine pathophysiology. Magnesium induces a relaxing impact within the physique by means of stimulating gamma-aminobutyric acid (GABA) receptors and limiting glutamate, an excitatory neurotransmitter within the CNS.⁸ People poor in magnesium are susceptible to nervous hyperexcitability, typically leading to migraines.⁸ Migraineurs with a magnesium deficiency could be handled prophylactically to stop assaults and scale back debility.⁸ We prescribed a magnesium complement within the well-tolerated type of magnesium glycinate to alleviate her complications and their accompanying signs. 

Sleep Enchancment 

Subsequent, we sought to enhance the affected person’s sleep, with the aim of eliminating her want for using zolpidem, partly resulting from its accompanying unwanted side effects, which included mind fog, dizziness, and fatigue. Research present sleep deprivation will increase general morbidity and results in comorbidities akin to melancholy and diabetes,⁹ so addressing sleep was a vital underlying issue to this affected person’s general well being. We chosen L-theanine as an alternative choice to promote sleep. L-theanine, an amino acid present in inexperienced tea, is believed to cut back the exercise of the excitatory neurotransmitter glutamate, permitting for sleep initiation and upkeep.¹⁰ Moreover, L-theanine might modulate the degrees of monoamines, together with serotonin, dopamine, and adrenaline. These compounds usually lower throughout sleep in a regulated CNS, leading to improved sleep high quality and faster restoration from exhaustion, thus permitting the affected person to wake feeling refreshed.¹¹ 

Psychological Well being Assist 

The etiology of melancholy, as with sleep problems, is usually based mostly in a neurotransmitter imbalance.¹² Antidepressants try to reinforce monoamine ranges, however their use can result in opposed results.¹³ The affected person famous important unwanted side effects coinciding with the initiation of sertraline, together with intention tremor, fatigue, dizziness, and insomnia, with out a noticeable alleviation of depressive signs. We prescribed a complement that included a number of monoamine precursors and cofactors, together with L-tyrosine and 5-HTP, offering constructing blocks for endogenous neurotransmitters.¹² 

Blood Sugar Regulation 

Lastly, we sought to handle the affected person’s prediabetes and fatigue, probably attributed to impaired insulin response. The polyvagal idea explains that in occasions of menace, dorsal vagal activation triggers elevated insulin exercise¹⁴; it’s an advantageous response within the short-term, although if extended, can result in insulin resistance by means of diminished insulin sensitivity.¹⁵ The affected person’s weight loss plan consisted of meats, rice, greens, and fruit. The affected person’s labs revealed blood glucose within the prediabetic vary, reflecting an insulin resistance image. To handle this, we requested the affected person to substitute brown rice for white rice,¹⁵ began her on the Ayurvedic herb gymnema (Gymnema sylvestre),¹⁶ and prescribed a day by day motion routine.¹⁷ Moreover, we prompt the homeopathic treatment Veratrum album, indicated for headache, dizziness, vomiting, and acidic craving,¹⁸ because the affected person reported juicing 10 tangerines per day. Complicated carbohydrates, like brown rice, provide extra fiber and a decrease glycemic load than white rice or juiced fruit, which spike insulin.¹⁵ Gymnema was chosen resulting from its efficacy in regulating blood glucose; when administered to people with insulin resistance, gymnema diminished fasting glucose and HbA1c scores and enhanced endogenous insulin.¹⁶ 

Comply with-ups & Outcomes 

The affected person acquired her first CST therapy, after which she famous the entire decision of her migraine within the workplace. She additionally skilled 10 minutes of incessant yawning following the therapy, and maybe most significantly, a profound realization concerning the connection between the numerous trauma she had skilled and the onset of her power complications, insomnia, and decline in psychological well being. 

On the affected person’s week-2 follow-up, she reported following our suggestions with none opposed results and skilled a noticeable discount within the length of her day by day migraines. Her cravings for acidic meals had utterly resolved, which she described as an enormous reduction. Signs of vertigo additionally resolved, and complications had change into extra intermittent. She was sleeping by means of the night time and her fatigue was enhancing. The affected person additionally disclosed that her tremor resolved after her PCP discontinued her prescription of sertraline. 

At 4 weeks, the affected person reported full decision of her migraines for a complete day following her second CST therapy, expressing that the absence of the headache allowed her psychological well being to rebound. In distinction to her earlier preoccupation with dying, she seen her ideas of dying dissolving as her vitality returned. The affected person resumed day by day actions, together with taking part in piano and yardwork, although she initially famous exhaustion following the exertion. Together with her hopelessness dissolving, she expressed a need for ongoing help and connection. She requested CST at every subsequent workplace go to, conveying her sense of empowerment upon recognizing the connection between her complications and her nervous system. At extra follow-up appointments, the affected person reported larger readability in cognition, quicker processing, and extra alertness. She reported elevated vitality and a renewed means to multitask. She famous her have to keep away from hectic ideas and feelings as they triggered migraines. 

By her 2-month go to, she had begun receiving extra, weekly CST therapies and reported alleviation of migraines for just a few days following every session. Right now, she reported elevated stress resulting from ongoing authorized proceedings associated to the trauma she had skilled, and this resulted in ruminating ideas resulting in insomnia. We addressed sleep hygiene, instructing avoidance of display screen time 1 hour previous to mattress¹⁹; reiterated the significance of day by day train²⁰; and prescribed melatonin, a hormone thought to control the sleep-wake cycle.⁹ To enhance her bedtime routine, we prescribed four-square respiratory, one other approach that deactivates a heightened sympathetic nervous system response.²¹ 

At 4 months, she reported migraines had diminished in severity and eventually felt manageable. She famous using four-square respiratory had utterly resolved her insomnia. She expressed renewed cognitive perform readability and said that her physique felt extra related following every CST session. Her PHQ-9 in workplace revealed her melancholy had dropped from extreme to gentle. 

Dialogue 

Traumatic occasions have the potential to stunt and even immobilize the physique by means of their results on the nervous system.² The polyvagal idea illuminates the complicated and dynamic mechanisms of human adaptive responses of the ANS. These embody the parasympathetic ventral vagal observe’s “relaxation and digest” state that embodies supportive social engagement and cues of security, the sympathetic nervous system’s “struggle or flight” state in response to hazard, and the parasympathetic dorsal vagal observe’s “freeze” state in response to excessive menace.³ This hierarchy of adaptive responses, crucial for survival within the short-term, can change into maladaptive if the system engages a sympathetic or dorsal vagal response that it can’t successfully disengage. Cueing the physique’s nervous system with indicators of security turns into important in defusing an activated state. Delicate physique work, akin to CST, is an choice that may present the physique with alerts to downregulate from an extreme state of both sympathetic or dorsal vagal tone. By approaching this affected person’s signs as a trauma response that led to a dysregulated nervous system, we have been in a position to goal our therapy on the underlying trigger; with correct security cues in place, this affected person may enhance every of her illnesses with extra naturopathic help within the type of herbs, vitamins, and way of life counseling. We witnessed our affected person rework from believing herself at dying’s door to in the end reengaging with life.
