Neurobiology of Addiction Part 2: Physiological Damage, Recovery, and Holistic Interventions

This episode, Part 2 of the neurobiology of addiction, delves into the profound physiological damage caused by chronic stress, trauma, and addiction, and outlines a multifaceted approach to recovery. It begins by recapping HPA axis activation and emphasizing the strong correlation between trauma, adverse childhood experiences (ACEs), and the development of mood and addictive disorders. The speaker highlights how trauma and addiction lead to increased emotional dysregulation, even to general negative stimuli, and how repeated HPA axis activation creates toxic environments in the brain, impacting brain chemistry and overall functioning.\n\nThe discussion then expands to specific physical complications, including compromised liver function (leading to neurotransmitter synthesis issues, neurotoxin buildup, malnutrition, and renal failure), and the additional challenges faced by individuals with uncontrolled diabetes (fatigue, irritability, HPA axis activation from low blood sugar, and impaired wound healing). The podcast explains hypercortisolism and hypocortisolism as protective but ultimately dysfunctional responses to chronic stress, leading to exaggerated stress responses (flat-to-furious) and increased risk of PTSD and relapse. It also touches on the impact of substance use and detox stress on the HPA axis, perpetuating these cycles of dysregulation.\n\nThe episode further details how addiction and HPA axis dysfunction alter major neurochemicals and hormones. It explains the impact on dopamine (arousal, motivation, attention), norepinephrine (energy, anxiety), glutamate (neurotoxicity), GABA (inhibitory control), serotonin (mood, cravings, sleep), thyroid hormones (t3, t4), and sex hormones (testosterone, estrogen), leading to a "wonky" system. Inflammation, autoimmune disorders, irritable bowel syndrome, and reduced pain tolerance are also presented as consequences of chronic HPA axis activation, underscoring the systemic nature of the damage.\n\nFinally, the podcast shifts to practical recovery strategies, emphasizing a holistic approach. Key recommendations include ensuring adequate nutritional building blocks for hormone and neurotransmitter synthesis (e.g., tyrosine for dopamine/norepinephrine, tryptophan for serotonin/melatonin, glutamine for glutamate/GABA, cholesterol for gonadal hormones), assessing and addressing hormonal imbalances with medical professionals, regulating circadian rhythms for sleep and hormone synchrony, developing stress tolerance skills to prevent HPA axis overstimulation, and actively increasing the natural release of beneficial neurochemicals through activities like deep breathing, laughter, and light exercise. The speaker stresses that recovery is a process of healing internal injuries, much like physical surgery, requiring patience and comprehensive support.

"There is a very strong correlation between trauma and addiction unfortunately when you you know factor out all of the potential confounds there is still a much higher rate of trauma in people with addictions than there is in the general population."

"The young brain is so much more what's the word I'm looking for able to be injured so much more sensitive to chemical changes and neurotoxicity."

"People with mood disorders or addictions are more likely to experience dysregulation of the HPA axis."

"Repeated activations of the HPA axis can create toxic environments in the brain."

"Low blood sugar activates the HPA axis so when somebody is diabetic they have a difficult time regulating their blood sugar when it goes low what happens the HPA axis is activated cortisol's release norepinephrine saliste which causes the release of what drumroll please blood glucose."

"Hypercortisolism is actually a protective mechanism designed to conserve energy during threats that are beyond the organisms ability to cope."

"When somebody has hypo cortisol ISM it perpetuates dysfunctional HPA axis activation."

"Recovery is multifaceted we need to ensure that people are providing their body the building blocks necessary to make the hormones and neurotransmitters and recover if you don't have the ingredients you can't make the soup."

"Just because this isn't a physical injury that we can see you know it is a physical injury but it's not like getting cut open for surgery just because it wasn't actual surgery doesn't mean we don't have jewelle injuries that need to heal."

"Light exercise will help increase serotonin levels so there's a lot of things that people can do and people can't even be doing you know right now."
