New research provides evidence that LSD alters the effects of brain stimulation and produces different and potentially larger changes in brain activity. The preliminary findings suggest that psychedelic drugs and brain stimulation may have a synergistic effect that could be used in innovative ways for treating various conditions. The proof-of-concept study has been published in the journal Psychedelic Medicine.
Psychedelic-assisted psychotherapy has shown promising potential as a therapeutic approach for various mental health conditions. This treatment combines the use of psychedelic substances, such as psilocybin or LSD, with psychotherapy sessions to enhance the therapeutic process.
The psychedelic substances used in this type of therapy are known to induce altered states of consciousness, leading to profound experiences that can have therapeutic benefits. These substances are thought to work by affecting brain receptors, particularly the serotonin 2A receptor, which influences perception, mood, and cognition.
These drugs have also been found to enhance neural plasticity, which refers to the brain’s ability to reorganize and form new connections. This may contribute to their long-term therapeutic effects. It is believed that combining psychedelic drugs with therapies like psychotherapy or brain stimulation could help direct these neuroplastic changes and lead to lasting behavioral changes.
“Current treatments like transcranial magnetic stimulation (TMS) have a large potential to help people with a variety of psychiatry disorders, however, these neuromodulatory treatments tend to have relatively short-lived effects,” explained study author Lucas Dwiel, a postdoctoral fellow at The Doucette Lab at the Geisel School of Medicine at Dartmouth. “So if we could prolong the effects of these treatments by first using drugs like LSD to make the brain more malleable or susceptible to change, we could help a large number of patients achieve their therapeutic goals.”
The researchers conducted experiments using rats to eliminate the biases inherent in human studies. The study focused on the effects of LSD and involved two main components: measuring brain activity changes after LSD administration and assessing the effects of brain stimulation combined with LSD.
