Behavioural and neurotoxic effects of ayahuasca infusion Banisteriopsis caapi and Psychotria viridis in female Wistar rat

Although this led to some brain injury, no permanent damage was detected. Treated animals showed higher neuronal activation in all brain areas involved in serotoninergic neurotransmission. In the forced swimming test, ayahuasca treated animals swam more than controls, a behaviour that was not significant in the fluoxetine group.

• They found no adverse effects on quality of life, measured by the CIS-R, and some participants showed significant improvements in mental health on the SF-36 as well as in minor psychiatric symptoms on the CIS-R.
• HAM-D is a questionnaire used to rate the severity of depression through the assessment of various aspects, such as mood, suicide ideation, insomnia, anxiety, or somatic symptoms.
• When administered in a laboratory, ayahuasca slightly increases heart rate and blood pressure 9,10, transiently increases prolactin and cortisol, and modifies immunological markers 11,12.
• Knowing what variables might predict eventual adverse effects may serve in screening of, or providing additional support for, vulnerable subjects.
• When analyzing the results, it was verified that the ingestion of ayahuasca led to a significant increase in phosphenic and original responses; however, this increase already occurred in the baseline .
• Four of these adverse states were negatively related to mental health, while the increase in “visual distortion” was related to better participants’ current mental health.

The participants were asked to rate every item on a seven-point Likert scale, ranging from 1 (Strongly disagree) to 7 (Strongly agree). The SWLS is five items long and includes sentences like In most ways, my life is close to my ideal; So far I have gotten the important things I want in life. The Satisfaction With Life Scale (SWLS) has been developed to quantify the life satisfaction component of subjective well-being (Diener et al., 1985). At the time of each measurement, a different (parallel) version of PCT was used to avoid learning effects.

Don’t Let Financial Worries Stop You from Getting Treatment

When designing different contexts of use, we did not create a category referred to taking ayahuasca in a cohesive group, something that future studies should consider. In our previous classical regression analysis, we found that being female significantly increased the risk of experiencing adverse states . Despite the necessary caution due to our study design, it is interesting to recall that fear has traditionally been linked to anxiety (e.g., ), and anxiety has been related to fearfulness (e.g., ). On the other side, higher increases of all the adverse effects, except for “Feeling nervous, anxious, or on edge,” was related to having a previous depressive disorder. Higher after use increases of “Hearing or seeing things that other people do not hear or see,” “Visual distortions,” and “Feeling ‘energetically attacked’ or a harmful connection with a spirit world” were observed in those participants with a higher frequency of ayahuasca use.

Life-threatening side effects and death have also been linked with ayahuasca use. Although Ayahuasca’s potential for addiction is not yet confirmed, its short and long-term side effects are disturbing. When combined, the two plants form a powerful psychoactive brew that impacts the central nervous system, producing hallucinations, out-of-body experiences, and euphoria.

Student’s t test was used to compare the means obtained for both samples of sub-study 2. When two CIs of the same variable did not overlap between different assessments, we calculated and reported the effect size (Cohen’s d). One-month and 6-months follow-up were conducted in order to relapse prevention rules observe potential changes in variables assessed. It is an assessment tool with cross-cultural validity that is used to assess the quality of life. It is a short but accurate tool for use in both clinical trials and epidemiological studies. These results suggest that the use of ayahuasca in controlled settings may offer therapeutic benefits.

• There are several reports regarding adverse effects of ayahuasca, leading some of them to psychiatric diagnoses29.
• The impact on mental health can be a bit more intense, both for good and for ill.
• It’s like ayahuasca provides a window of opportunity for the brain to rewire itself, potentially allowing people to step out of deeply ingrained patterns of substance abuse.
• Additionally, it was found that the mice used in the study, treated with DMT, performed better in memory tests than the animals in the control group .
• Only 16.0% (865) of the participants had not used ayahuasca during the previous year, while 59.9% (3,236) had used ayahuasca more than 31 times and 20.0% (1,079) had used it more than 397 times in their lifetime.

Statistical analysis

In a study with a sample of 380 regular Spanish ayahuasca users (47% women), there were no differences between genders in the GHQ-12 questionnaire, which measures mental health, while in the general population men have 10 points better mental health than women . Despite 10 post-ayahuasca use adverse mental states being initially included in the analyses, only 5 were significantly related to participants’ current mental health. Experiencing extreme fear during ceremonies and prior anxiety disorders, linked to emotional processing, warrant further study to better manage adverse post-ayahuasca mental states and enhance positive outcomes. As indicated in previously cited studies 32,41,42,76, the results from various analyses performed showed that more ayahuasca use is related to better current mental health in users. In this extended analysis of the adverse mental states after ayahuasca use based on data from the Global Ayahuasca Survey (GAS) , we have used machine learning and statistical analysis to identify specific relationships between these adverse mental states, participants’ current mental health, and key influencing factors. Further analysis of other variables collected in the GAS revealed improvements in mood disorders such as anxiety and depression , as well as reductions in alcohol and drug use , enhancements in mental health and wellbeing , and changes in life and lifestyle .

For people living with or researching certain mental health conditions, it may be a long-hoped-for breakthrough. CAPE was designed specifically to evaluate psychotic-like experiences in epidemiological studies in the general population. Better scores for depression were also observed among long-term users when compared with ayahuasca-naïve users at baseline. However, further studies using larger samples should consider potential differences between the type and setting of the ceremony. This lends support to previous research that found that ayahuasca users gained therapeutic benefits or experienced an enhanced ability to solve personal problems25,33,46.

Brain Short Circuit: Causes, Symptoms, and Treatment Options

Thus, after interviewing 13 therapists who use ayahuasca for that purpose, 14 individuals who had undergone ayahuasca-assisted therapy for addictions and 2 specialist researchers were used. Another investigation, carried out by Loizaga-Velder et al. , also evaluated the use of ayahuasca in the treatment of addictions. Additionally, inclusion in a community plays an important role in therapeutic potential . This increase was also observed in the region of the medial orbital cortex in the groups treated with naltrexone, ayahuasca 1×, ayahuasca 2× and in the control . The results revealed that the groups treated with naltrexone and ayahuasca did not lead to a decrease in ethanol intake .

Bouso et al. compared two groups of ayahuasca users, one with long term experience and the other with occasional use. Sanches et al. reported increased blood perfusion in the left nucleus accumbens, right insula, and left subgenual area eight hours after ayahuasca ingestion and that ayahuasca was well tolerated. In a research study based on results from the Ayahuasca Researcher’s Behavioral Observation Scale (ARBOS), Shamanic Experience and Net Benefit scales, and the Temperament and Character Inventory Predictor scale, Burton suggests we can predict which patients would benefit from or be harmed by participating in an drinking age map ayahuasca ceremony. In a 2012 study, Bouso et al. compared a variety of psychological measures in ayahuasca users against matched controls. Barbosa et al. concluded that religious use of ayahuasca “does not adversely affect neuropsychological functioning and may have positive effects on substance abuse and mood”. In another more recent study, Barbosa et al. looked at regular ayahuasca users within a religious setting.

4. Study Selection and Data Extraction

Perhaps most intriguing are the potential long-term effects on emotional processing. It’s as if ayahuasca use might be rewiring the brain’s communication pathways over time, potentially leading to lasting changes in how we process information and regulate our thoughts and emotions. This boost in neuroplasticity might explain why many people report profound, lasting changes in their thinking and behavior after ayahuasca experiences. One of the first things researchers noticed when studying the brain on psychedelics like ayahuasca was a significant alteration in brain wave patterns. This interaction is thought to be responsible for many of the psychedelic effects experienced during an ayahuasca journey.

4. Brain Structures Involved in the Ayahuasca 
Experience

Husbands et al. suggested that the imidazoline type 2 (I2) receptors may play a role in the hallucinogenic nature of ayahuasca given that harmine and harmaline have much higher affinities for the I2 receptor than the 5-HT2A receptor. Certain beta-carbolines have been found to bind at imidazoline binding sites, including harmine and harmaline found in ayahuasca . A study on the nucleus accumbens of rats found that harmine increases electrically evoked DA efflux in the nucleus accumbens shell. These opposite effects on the level of inhibitory neurotransmission in these two limbic structures may provide some explanation into the behavioural effects of ayahuasca, due to the importance of these structures in neural pathways involved in memory, learning, and emotion.

What Are the Long-Term Effects of Ayahuasca?

However, our previous study did not analyze the relationship of the adverse mental states with the participants’ current mental health. Recently, we published a report in which we reviewed all the scientific knowledge reporting ayahuasca’s adverse effects, and where we also reported the adverse effects collected in the Global Ayahuasca Survey (GAS), a survey conducted on more than 10,000 subjects who attended an ayahuasca ceremony, comprising participants from more than 50 countries . Ayahuasca has also attracted the interest of scientists for its potential benefits on mental health, but its adverse effects are under-researched. In the present study, the original, English version was used to acquire a better understanding of the experiences the participants had about ego dissolution during the ayahuasca ceremony. Harris and Gurel reported that ayahuasca users scored higher in the areas of Joy in Life and Relationship to the Sacred, and had an experience just as difference between na and aa spiritual as the Catholic retreat participants, and also had reduced alcohol consumption, healthier eating, better mood, and self-acceptance. The results obtained in this study help to inform us about the effects of the ritualistic use of ayahuasca on mental health.

But what exactly is ayahuasca, and why has it become such a hot topic in recent years? I can now say that psychiatric medication saved my life. However, I do have to humbly acknowledge that I was not prepare for such an experience. Nowadays, everyone can do ayahuasca, and ayahuasca is not for everyone.

After treatment with ayahuasca, there was a significant reduction in C-reactive protein levels . After analyzing the results, it was possible to verify that before treatment, the group of patients with depression had higher levels of C-reactive protein than the control group. For this purpose, blood samples were collected before and 48 h after ingestion of the substance under study in order to verify the concentration of inflammatory biomarkers. In a study developed by Bussmann et al. , the minimum inhibitory concentration (MIC) of several plant extracts, namely B. However, positive results have been found in the various other purposes, which influence well-being, reported above. Weiss et al. studied the association between the ceremonial use of ayahuasca and changes in personality traits.
