This nonrandomized clinical trial assesses associations between psilocybin therapy and changes in systemic markers of inflammation and mitochondrial stress in people with Parkinson disease and mood dysfunction.
BACKGROUND Psilocybin, a serotonergic psychedelic found in hallucinogenic mushrooms, is metabolized to psilocin, the compound responsible for its psychoactive effects. Psilocybin has demonstrated therapeutic potential for neuropsychiatric conditions. While recent trials have primarily used orally administered synthetic psilocybin, alternative formulations and delivery methods may offer...
BACKGROUND: Ketamine is an effective rapid-acting treatment for treatment-resistant depression (TRD), producing antidepressant effects within hours of administration. Because it induces states of heightened neuroplasticity and psychological openness, psychotherapy may enhance its therapeutic effects. METHODS: This exploratory, nonrandomized, open-label clinical trial evaluated the adjunctive...
Background Ketamine has emerged as an effective rapid-acting treatment for treatment-resistant depression (TRD), producing significant antidepressant effects within hours of administration. Given ketamine’s capacity to induce states of heightened neuroplasticity and psychological openness, psychotherapy may represent a meaningful complement to its pharmacological effects — facilitating...
The use of psychedelics in the treatment of psychopathologies has been expanding, highlighting Psychedelic-Assisted Psychotherapy (PAP) as a promising resource in mental health care. This systematic review investigates. This systematic review investigates whether and how cognitive-behavioral therapies are integrated with psychedelic substances—both classical and atypical—for the treatment of...

There is promise for 3,4-Methylenedioxymethamphetamine (MDMA)-assistedpsychotherapy as a highly effective and durable treatment for posttraumatic stress disorder(PTSD). However, the Food and Drug Administration rejected MDMA-assisted psychotherapy inits current form, expressing concerns about the lack of standardization and empirical basis ofpsychotherapy methods. This highlights the need to...
Psychedelic-assisted therapy (PAT) is gaining recognition as a promising intervention for treatment-refractory mental health conditions in adults. While interest in its applications for adolescents is growing, critical gaps remain in understanding safe and effective delivery of PAT to this vulnerable population, including implications for caregiver/family (used interchangeably) involvement in...
Mood dysfunction is highly prevalent in Parkinson's disease (PD), a main predictor of functional decline, and difficult to treat-novel interventions are critically needed. Psilocybin shows early promise for treating depression and anxiety, but its potential in PD is unknown, as safety concerns have excluded people with neurodegenerative disease from previous trials. In this open-label pilot...
A lack of diverse and representative participant samples in mental health intervention research perpetuates mental health disparities. This issue has become a salient concern in studies of psychedelic-assisted psychotherapy (PAT), which is emerging as a promising mental health intervention. This systematic review evaluates the reporting, representation, and analysis of participant...
There is notable controversy about the role of psychotherapy in clinical trials of psychedelic-assisted therapy (PAT). This heated and perpetually evolving debate informs questions such as how much therapy should accompany a psychedelic intervention (Marseille et al. , 2022), what type of therapy most effectively complements psychedelic administration (Cavarra et al. , 2022;Yaden et al. ,...
Psychedelic-assisted psychotherapy (PAP) has emerged as a potential treatment for a variety of mental health conditions, including substance use disorders and depression. Current models of PAP emphasize the importance of psychotherapeutic support before, during, and after ingestion of a psychedelic to maximize safety and clinical benefit. Despite this ubiquitous assumption, there has been...
In recent years a renewed scientific, public and commercial interest in psychedelic medicines can be observed across the globe. As research findings have been generally promising, there is hope for new treatment possibilities for a number of difficult-to-treat mental health concerns. While honouring positive developments and therapeutic promise in relation to the medical use of psychedelics,...
Background: An emerging controversy in psychedelic therapy regards the appropriateness or necessity of psychedelic therapists having personal experience using psychedelics themselves. Although there are a number of potential advantages and disadvantages to personal use among psychedelic therapists, no studies to date have measured their use or other aspects of their training. Materials and...
In recent years, there has been a significant focus on exploring the potential therapeutic impact of altered states of consciousness on treatment outcomes for mental illness, with the goal of enhancing therapeutic strategies and patient results. This meta-analysis was designed to investigate the potential link between the psychomimetic effects of ketamine and clinical outcomes in mental health,...
