@SFDom415 I'm not actually support to talk about 'recs' on EVO but this is a medical case, so I'll do a short write up for you below:
The topic of using substances like ketamine or psilocybin mushrooms (often referred to in the context of "microdosing") for therapeutic purposes is quite intriguing and has been the subject of increasing research and discussion in recent years (I personally studied it on and off). These substances are believed by some researchers to offer potential benefits for certain mental health conditions, such as depression, anxiety, and PTSD, through mechanisms that might include the repair or growth of neuronal connections, among other effects. The theory you mentioned about repairing worn-out connections in the brain aligns with some of the hypotheses being explored in scientific studies. (I will cite a few studies below)
Ketamine, for instance, has been approved in a nasal spray form for treatment-resistant depression in the United States, indicating a level of recognition for its therapeutic potential under specific conditions. Similarly, research into psilocybin mushrooms has shown promising results for depression and anxiety, especially in cases where patients have not responded well to traditional treatments.
The conversation around microdosing, particularly with psilocybin, often includes anecdotal reports of improved mood, creativity, and cognitive function, yet scientific research in this area is still in the early stages.
Studies on the topic:
Ketamine for Depression:
A study published in the "American Journal of Psychiatry" in 2019 found that
ketamine significantly reduced depression symptoms in patients who had not responded to at least two other forms of treatment. The study highlighted ketamine's rapid action in alleviating symptoms, often within hours or days, which is a significant advantage over traditional antidepressants that may take weeks to become effective. Reference: JAMA Psychiatry, "Efficacy of Intravenous Ketamine for Treatment of Chronic Posttraumatic Stress Disorder: A Randomized Clinical Trial," 2019.
Psilocybin for Depression and Anxiety:
Research published in "The New England Journal of Medicine" and "JAMA Psychiatry" in 2020 presented findings from a randomized controlled trial
comparing psilocybin with a conventional antidepressant (escitalopram) for the treatment of depression. The study found that psilocybin was as effective as escitalopram in reducing depression symptoms, suggesting it could be a viable alternative treatment. Additionally, a 2016 study in the "Journal of Psychopharmacology" found that a single dose of psilocybin significantly reduced depression and anxiety symptoms in cancer patients, with effects lasting up to six months. References: NEJM, "Trial of Psilocybin versus Escitalopram for Depression," 2020; Journal of Psychopharmacology, "Rapid and sustained symptom reduction following psilocybin treatment for anxiety and depression in patients with life-threatening cancer: a randomized controlled trial," 2016.
Mechanisms of Action:
Studies investigating the mechanisms by which
ketamine and psilocybin exert their effects suggest that both substances may promote neuroplasticity—the brain's ability to form new neural connections—potentially explaining their therapeutic benefits. Ketamine, for instance, has been shown to increase the levels of a neurotransmitter called glutamate, which then stimulates the growth of synapses, essentially rewiring parts of the brain that are involved in mood regulation. Psilocybin appears to decrease activity in the brain's default mode network, a network thought to play a role in self-referential thoughts and the ego, which could be why it's effective in treating conditions like depression and anxiety.
