Ketamine for anxiety: a simple guide to new findings

Anxiety disorders are increasingly prevalent and often respond poorly to standard treatments such as SSRIs or benzodiazepines. Growing evidence suggests ketamine-assisted psychotherapy may offer rapid relief, particularly in treatment-resistant anxiety. By modulating glutamate via NMDA and AMPA receptors, ketamine enhances neuroplasticity and may reduce pathological worry within hours or days. Clinical trials show benefits in social and generalized anxiety, and real-world studies report sustained symptom reduction and decreased suicidal ideation. When combined with psychotherapy and integration, ketamine may help consolidate meaningful and lasting change.

The potential of ayahuasca assisted with psychotherapy in acute grief processes: a scientific and artistic exploration

Recent research suggests ayahuasca-assisted psychotherapy may support people facing acute grief. In a structured therapeutic setting, ayahuasca was associated with reduced grief severity, fewer prolonged-grief symptoms, and greater post-traumatic growth. The study compared ayahuasca-assisted therapy, psychotherapy alone, and no intervention, finding the strongest improvements when ritual, psychotherapy, and community support were combined. Results indicate ayahuasca may help integrate loss by easing pain while preserving emotional connection to the deceased, offering a humane complement to existing grief care within ethically guided clinical frameworks.

Neuroplasticity and ketamine: a new horizon in mental health

Depression, anxiety and chronic stress are associated with the loss and retraction of dendritic spines, disrupting communication between key brain regions involved in emotion, memory and decision-making. This disconnection reduces cognitive flexibility and promotes rumination and rigid negative patterns. Ketamine and other psychedelics have been shown to rapidly enhance neuroplasticity by increasing the formation and stabilization of dendritic spines, reopening critical learning periods. When combined with psychotherapy and supportive habits, this window of plasticity can facilitate lasting emotional and behavioral change.

Ketamine administration methods

Ketamine-assisted psychotherapy can use several routes of administration, each with different pharmacokinetic profiles. This article explains bioavailability and half-life, and compares intramuscular, intranasal and oral ketamine. Intramuscular administration offers very high bioavailability, rapid onset and longer half-life, while intranasal delivery has moderate bioavailability and shorter duration, and oral use shows slower onset and lower absorption. Based on these factors, the clinic prioritizes intramuscular injection as a balanced option combining efficacy, predictability, patient comfort and clinical safety in routine ketamine-assisted psychotherapy settings.

Psilocybin – what is it, and what is its current legal status?

Psilocybin is a naturally occurring psychedelic found in certain mushrooms with a long history of ritual use. Research shows it can alter perception, mood and sense of self, often producing meaningful or mystical experiences. Recent studies highlight potential benefits for depression, anxiety, addiction and grief, linked to temporary increases in brain connectivity and neuroplasticity. Evidence supports structured, high-dose sessions combined with psychotherapy, while microdosing lacks solid support. Despite advanced clinical trials in the US and Europe, psilocybin remains illegal in Spain and is not offered clinically.

Ketamine-assisted therapy in the treatment of grief for the loss of a loved one

Prolonged or complicated grief affects around 10% of bereaved people and is marked by persistent longing, intense emotional distress, and functional impairment. Current evidence shows only moderate benefits from psychotherapy and no proven efficacy of medication alone. Recent research highlights psychedelic-assisted therapies as promising alternatives. Ketamine-assisted therapy may support grief treatment through two complementary mechanisms: a neurobiological window of enhanced neuroplasticity that increases psychological flexibility, and meaningful altered-state experiences that facilitate acceptance, emotional processing, and the reconstruction of personal narratives around loss.

Psilocybin and depression

Psilocybin-assisted therapy is emerging as a promising approach for depression, particularly treatment-resistant cases where standard antidepressants show limited efficacy and burdensome side effects. Research suggests psilocybin can produce rapid and sustained reductions in depressive symptoms, partly by enhancing neuroplasticity and facilitating meaningful psychological experiences. When embedded in a structured therapeutic model with preparation, dosing, and integration sessions, psilocybin may foster emotional openness, cognitive flexibility, and long-term positive change, highlighting a potential paradigm shift in how depression is treated within modern clinical research frameworks.

Music in psychedelic-assisted therapy

Music has played a central role in psychedelic practices for centuries and is now recognized as a key therapeutic component in psychedelic-assisted therapy. Research shows that psychedelics heighten emotional responsiveness to music, transforming it into an active guide for inner exploration. Carefully selected music can evoke deep emotions, access unconscious material, and support transformative or mystical experiences. By amplifying emotional processing and reducing psychological defenses, music helps patients surrender to the experience, facilitating insight, emotional release, and therapeutic change that is difficult to reach through verbal therapy alone.

Ketamine for chronic neuropathic pain

Chronic neuropathic pain is often severe, persistent, and poorly responsive to conventional treatments such as anti-inflammatories or opioids. Ketamine has emerged as a promising option by modulating NMDA receptors involved in pain perception and memory. Clinical studies show that ketamine can significantly reduce pain for weeks, particularly in complex neuropathic conditions. Beyond analgesia, ketamine may also improve comorbid depression and PTSD, which frequently accompany chronic pain. When combined with psychotherapy, ketamine offers an integrative approach addressing both physical suffering and psychological distress.

Fear, trauma and MDMA

Fear is a fundamental emotion that protects us, but when it becomes chronic it can lead to disorders such as phobias and post-traumatic stress disorder (PTSD). Conventional treatments often show limited efficacy, prompting new approaches like MDMA-assisted psychotherapy. Research promoted by Multidisciplinary Association for Psychedelic Studies (MAPS) and led by figures such as Rick Doblin suggests that MDMA can reduce fear responses, enhance emotional processing, and strengthen the therapeutic alliance. These effects may allow patients to revisit traumatic memories with less avoidance, fostering recovery and improved quality of life.
