Psilocybin and Depression; Psychedelics Can Reset Brain Function

Background created by fractal geometry.

Psychotropic plants once considered taboo are now being used as highly effective clinical solutions for treating a number of psychological issues, including depression, PTSD, and end-of-life anxiety.

And recent studies have gained traction using psilocybin, the psychoactive compound in ‘magic’ mushrooms, as a successful treatment for depression. The study found evidence of a reset mechanism in the brain triggered by psilocybin that can have lasting effects.

Psilocybin & Depression

A calm, relaxed feeling in the hours, days, and weeks after using psilocybin is familiar to those who have taken it before. This is sometimes referred to as an “after-glow,” and many attribute this to the sense of profundity or universal insight acquired during the experience. This sensation is often subjective and fleeting – something that would be difficult to measure in a lab.

But now a team of researchers has set out to measure this feeling and the potential it has for use as a clinical treatment for depression and anxiety. These researchers believe they have possibly recorded this reaction and noticed a reconfiguration of the neural pathways in patients, which they say have become narrowly reinforced in people experiencing severe depression and anxiety. Their research appears to show what they call a disintegration and reintegration in which psilocybin acts as a “reset mechanism.”

This test, conducted by researchers at Imperial College London, looked not only at subjective measures of how patients felt in the days and weeks after receiving a dose of psilocybin but also more objective measures seen in brain scans that monitor cerebral blood flow and functional connectivity. The scientists focused on the amygdala, an area of the brain where emotion, behavior, and motivation are processed, noticing that decreased cerebral blood flow to this particular location correlated with reduced depressive symptoms.

The amygdala is directly connected to the prefrontal cortex, controlling a sort of back and forth process for measuring fear. This is basically where your fight or flight response plays out. The amygdala acts as our alarm system, sending a signal to the prefrontal cortex, which in turn tells it whether that threat is something to actually be concerned about. It’s thought that higher activity in the amygdala leads to lower activity in the prefrontal cortex which causes anxiety and depression.

This has led scientists to see psilocybin as an appropriate medicine for people experiencing anxiety and depression. But psilocybin isn’t the only psychedelic shown to have this effect. And while these material observations seem to correlate things like blood flow and electrical activity with those positive changes, some still maintain that the mystical psychedelic experience rather than the plant is what is so palliative.

LSD for Depression

Similar studies have been undertaken with LSD in place of psilocybin, providing similar results. The most well-known trials have been conducted by MAPS, the Multi-Disciplinary Association for Psychedelic Studies, a group that has been working on advancing clinical research with psychedelic and empathic drugs for the treatment of depression, anxiety, and PTSD.

A 2014 study administered LSD to 12 patients experiencing severe depression, anxiety, and end-of-life anxiety, 11 of whom had never taken the drug before. Nearly all who completed the trials expressed the desire to receive more treatments in the future due to their notably positive experiences.

One subject said the experience caused a marked shift in her values to make time for things that were more important in life, like family. Another subject with end-of-life anxiety found that after her LSD experience she found humor in her illness and looked at herself as part of a larger cosmic entity rather than an individual. Meanwhile, all subjects reported no lasting adverse side effects after the experience.

While these clinical studies show promise and work well in closely monitored environments accompanied by professional psychotherapy sessions, many remain unconvinced due to the smaller data set of studies and subjects. But this is primarily due to strict laws preventing these trials as well as difficulty obtaining compounds from legitimate sources.

However, a recent shift in the public perception regarding psychedelics and cannabis seems to be bucking the trend. Meanwhile, groups like MAPS and the Beckley Foundation are helping ease the stigma, stating their belief that more psychedelic compounds will be approved for clinical use in coming years.

Ketamine Depression Treatment

Clinical trials for treating depression with LSD and psilocybin often lead critics and journalists to harken back to the ’60s and make some clichéd quip about the hippie generation, or their brief stint experimenting with drugs in college. But when it comes to ketamine, personal anecdotes are fewer and far between. This drug, which tends to also fall into the recreational club-drug scene, has shown some profound results when it comes to its potential for treating severe depression, especially for those who are suicidal.

Though ketamine for treating depression is considered an off-label drug, one that is used for a purpose other than what it is labeled for, it has shown unprecedented results. Typically used as an anesthetic, in large doses ketamine is a highly psychoactive hallucinogen, and also an antidepressant.

People who are suicidal and have not had success with typical antidepressants have seen drastic changes within a few hours of ketamine treatment. Researchers believe that ketamine acts on glutamate, rather than serotonin and dopamine, the chemicals most antidepressants focus on. This particular channel can cause drastic changes and overnight transformation in attitudes of people suffering from severe depression.

Of course, doses high enough to achieve this effect are incapacitating and can be difficult to deal with. The psychedelic effect of ketamine can lead to “k-holes” or feelings of intense and sometimes frightening psychedelic experiences often paired with paralysis. This has lead doctors to search for drugs that can target the glutamate in the brain, but skip a burdensome trip.

While these drugs have amazing potential to help solve mental issues that plague large percentages of society, there needs to be a shift in drug policy to allow them to be rescheduled. Almost all of these drugs are Schedule 1, classified as having no medical value, but clearly, there is plenty of evidence to the contrary.

While their use should be monitored and administered in a controlled set and setting, their criminalization prevents people from taking advantage of the positive results scientists are seeing. And when an effective drug is made illegal, it can lead to those who need it seeking it out on the street where purity and quality aren’t guaranteed.

Is Psychedelic Tourism Destroying the Sanctity of Plant Medicine?

As psychedelic healing and plant medicine go more mainstream, luxury psychedelic tourism is on the rise—good news for the spread of this medicine, but how might over-commercialism affect this sacred practice?

A recent Bloomberg article highlights the rise in all-inclusive psychedelic retreats. Indigenous plant medicine has been around for centuries, and its health benefits have been scientifically demonstrated, but as it gains mainstream acceptance and finds a bigger audience, some only see dollar signs.

Bloomberg reports, “according to Data Bridge Market Research the psychedelic market is expected to grow from $3.8 billion in 2020 to $10.7 billion by 2027.”

With the potential to make a lot of money, could some unscrupulous companies capitalize on this trend and remove the sanctity of this practice?

Carlos Tanner is the director of The Ayahuasca Foundation in Peru, he founded the center in 2009 as the result of his own healing journey. “When I started our retreat center, The Ayahuasca Foundation, I was coming off of a seven-year study myself; a four-year apprenticeship where I lived with a curandero and several years after that of studying with other teachers,” Tanner said.

“For most people that were starting centers at that time—which wasn’t many—you were a student first, and eventually after years of study, you came to the point where you wanted to offer this to people from outside of the culture. Now we see people who don’t have very much experience at all, but yet they’re opening a healing center.”

As this budding industry is dealing with rapid growth, there are some complicated issues regarding its increased popularity.

“When it comes to the commercialization of substances that have an ancestral background I would say that it is a delicate situation, and I hope that there would be a benefit to those indigenous populations from which those traditions were orignated. But at the same time, I know many indigenous people and they are for the spreading of what they believe to be their culture, which oftentimes was something that was looked upon negatively or was degraded as if they were second-class citizens, quite literally,” Tanner said.

“But now having people from the Western world, from the modern world, want to learn or experience elements of their culture, I think gives them a sense of pride. So it’s a complex question, to say the least.”
