Brain Under Siege: Demystifying the Neuroscience of PTSD

  • PTSD What We Know and What we Don't

    9 ENE. 2024 · Post-traumatic stress disorder, or PTSD, is a complex disabling psychiatric condition that can develop after someone experiences or witnesses a profoundly disturbing, frightening or life-threatening event. The trauma triggers a cascade of physiological and psychological symptoms interfering with daily functioning and overall wellbeing. Who PTSD Impacts PTSD can impact anyone who has gone through severe emotional or physical trauma regardless of gender, age, nationality or background. However, certain populations face disproportionately higher risk including: - Military veterans exposed to combat violence - Victims of violent crimes like sexual assault, child abuse, domestic violence, mugging, terrorism - Refugees fleeing warzones, persecution or natural disasters - First responders handling catastrophic accidents with casualties - Patients surviving critical health episodes through emergency interventions Not everyone exposed to trauma develops PTSD which depends on unique risk factors like trauma severity, available social supports, inheritance patterns, childhood adversity levels, and tendency for dissociation or panic responses. But an estimated 8 million American adults have PTSD in a given year with women twice as likely to develop it as men. Global prevalence ranges between just under 4% in peace regions to over 15% in conflict areas. PTSD Causes & Symptoms When external threats like violence or accidents trigger the body’s natural survival “fight or flight” stress response, a flood of adrenaline, cortisol and neurotransmitters alter functioning for quick reaction. Heart rate elevates. Pupils dilate scanning for danger as breathing intensifies circulating oxygen to large muscles prepping to confront the threat. Non-essential bodily processes like digestion shut down to conserve energy for emergency alertness. Under normal circumstances when threats pass, the parasympathetic nervous system kicks in a calming hyper-aroused “fight or flight” response bringing equilibrium. But for PTSD sufferers this off-switch fails leaving systems stuck in overdrive cycles of hypervigilance exhausting the mind and body long after the crisis stabilized. The traumatic memory imprints intense associations linking environmental cues to overwhelming panic. The psyche struggles to integrate shattering experiences outside normal realms into a cohesive understanding of self and world. Core PTSD clusters include: 1) Intrusive memories forcibly reliving the trauma through flashbacks, nightmares, and emotional/physical distress when recall triggers manifest 2) Avoidance of people, places or scenarios reminiscent of the events. Emotional numbing, withdrawal, and selective amnesia lock trauma in the subconscious but sap joy too. 3) Negative thought/mood shifts like survivor’s guilt, shame, difficulty recalling details worsened by lack of sleep or irritable overreactions 4) Heightened arousal levels through aggressive, erratic or self-destructive behavior. Hypersensitivity manifesting as constant anxiety hampers function PTSD Treatment Method History & Options As greater numbers returned from 20th-century wars or survived accidents that would have killed previous generations, psychological trauma echoes became increasingly apparent. But medical understanding evolved slowly from dismissing shell shock and battle fatigue as cowardice to linking PTSD onset to neurological changes. 1950’s-60’s Treatments Though still mistaken as rare rather than widespread among survivors, early roots of formal interventions emerged via: - Psychoanalytic talk therapy allows the discharge of avoided memories - Anxiety and arousal reduction techniques like hypnosis or systematic desensitization joint with cathartic flooding exposure methods 1970’s-80’s Trauma Therapy As Vietnam veteran’s advocacy broadened PTSD perspective, treatment incorporated further techniques: - Cognitive processing therapy focusing on stuck trauma beliefs blocking growth - EMDR intensive memory stimulation while incorporating bilateral eye movement - Group talk sessions to normalize common symptoms among populous building support - Medications like SSRIs alleviating anxiety, depression and insomnia also helped manage (not cure) distress Integrative 21st Century Gold Standards Today's “gold standard” consensus favors combining therapies in coordinated 12-week programs: - Stabilizing symptoms through SSRIs to establish a safe baseline - Education on PTSD brain adaptations providing self-compassion - Altering misassigned danger associations using systematic desensitization - Challenging distorted automatic thinking through cognitive techniques - Carefully progressively exposing patients to avoided trauma narratives via writing, telling or virtual reality while preventing destabilizing overwhelm Additional promising options gaining evidence include: - FDA research ongoing around using MDMA or cannabis derivatives to amplify talk therapy benefits - Mindfulness-based stress reduction through trauma-sensitive meditation/yoga protocols - Transcranial magnetic stimulation targeting memory emotional intensity centers - Ceremony or ritual to construct coherent trauma narrative with communal support Broader PTSD societal destigmatization and trauma-informed care also spread concentrating not just on individual treatment but transforming systems preventing compounding harms. While PTSD remains challenging, better-recognizing prevalence and integrating survivors back into supportive communities aids healing. In summary, PTSD constitutes a very treatable but often difficult condition arising from exposure to severely distressing events outside normal experience flooding healthy coping reserves. Growing knowledge around root causes, brain changes and gold standard multi-modal treatments continues progressing prognosis, functionality and support networks for impacted individuals through societal change accelerating destigmatization. But by increasing awareness and emotional intelligence around trauma responses we all gain the power to foster post-traumatic growth over paralysis. Thanks for listening to Quiet Please.

  • Ibogaine shows promise

    9 ENE. 2024 · Ibogaine and PTSD: A Promising Path with Cautious Steps Several recent studies, including a particularly noteworthy one published in Nature Medicine in December 2023, have highlighted the potential of ibogaine to significantly reduce symptoms of PTSD. Here's what we know: What is Ibogaine?: Ibogaine is a naturally occurring psychedelic drug found in the Tabernanthe iboga plant, native to West Africa. It has a complex pharmacological profile, acting on various neurotransmitter systems in the brain. Traditionally used in religious and healing rituals, it's also gaining traction in the treatment of various mental health conditions, including PTSD. The Recent Study: The Nature Medicine study focused on 30 military veterans diagnosed with PTSD and severe co-occurring psychiatric conditions, like depression and anxiety. Participants received a single oral dose of ibogaine, followed by psychological support. After one month, researchers found: - 88% reduction in PTSD symptoms: This is significantly higher than the effects of traditional PTSD treatments like medication and therapy. - 87% reduction in depression symptoms - 81% reduction in anxiety symptoms - Improved cognition and overall functioning: Participants reported feeling more focused, motivated, and connected to others. Mechanism of Action: While the exact mechanism by which ibogaine works for PTSD is still under investigation, it's believed to involve several factors: - Resetting the brain: Ibogaine may act as a "brain reset," reducing activity in areas associated with trauma and fear, and promoting neuroplasticity, the brain's ability to adapt and form new connections. - Processing and integrating trauma: The psychedelic experience induced by ibogaine might allow individuals to safely confront and integrate their traumatic memories, leading to emotional healing and closure. - Reduced inflammation: Some research suggests ibogaine may have anti-inflammatory properties, potentially benefiting conditions like PTSD, where inflammation is linked to symptom severity. Cautious Optimism: While these findings are promising, it's important to note several caveats: - Small sample size: Larger studies with longer follow-up periods are needed to confirm the long-term efficacy and safety of ibogaine for PTSD. - Intense experience: The ibogaine experience can be physically and emotionally challenging, requiring careful monitoring and support in a controlled setting. - Legal restrictions: Ibogaine is currently classified as a Schedule I drug in the US and many other countries, meaning it has a high potential for abuse and no currently accepted medical use. The Road Ahead: Despite the limitations, these studies represent a significant step forward in the search for effective PTSD treatments. Further research, coupled with regulatory changes, could pave the way for ibogaine to become a valuable option for individuals suffering from this debilitating condition. Additional Points: - Ibogaine is not a cure-all, and its potential side effects and risks should be carefully considered. - Combining ibogaine with traditional therapies may offer optimal results. - Continued research is crucial to understand the long-term effects and refine treatment protocols. - Ethical considerations and responsible use are paramount in exploring this promising avenue. Remember, this information is not a substitute for professional medical advice. Always consult with a qualified healthcare professional before considering any new treatment for PTSD. I hope this provides a comprehensive overview of the recent research on ibogaine and its potential for PTSD treatment. Stay informed, stay hopeful, and continue advocating for accessible and effective mental healthcare for all. Thanks for listening to Quiet Please.
