A biopsychosocial approach to ketamine for treatment-resistant depression, called the Montreal model, pairs ketamine infusions with structured psychiatric care and psychotherapy. Developed over six years in public healthcare settings, the model conceptualizes ketamine as a brief intervention that creates windows of opportunity for enhanced care and psychological growth. It combines six ketamine infusions with psychedelic-inspired nonpharmacological adjuncts, including preparative and integrative psychological support. The model aims to bridge biomedical and psychedelic perspectives, offering a standardized yet flexible approach for severe, real-world patients. Further research is needed to assess its effectiveness and hypothesized psychological mechanisms.

A prospective longitudinal survey of eight Canadians with cancer who received legal psilocybin-assisted psychotherapy under Section 56 exemptions found significant improvements in anxiety, depression, pain, fear of COVID-19, quality of life, and spiritual well-being two weeks after the session. Attitudes toward death, medical assistance in dying, and desire for hastened death remained unchanged. Most participants found the sessions highly meaningful, though one reported a substantial decrease in well-being. These preliminary data suggest that real-world psilocybin-assisted psychotherapy can produce psychiatric benefits similar to those in clinical trials, but limited enrollment and negative experiences indicate a need for formal real-world evaluation programs.

A randomized controlled trial will test whether virtual-reality-guided meditation is feasible and acceptable for reducing stress, anxiety, and depression in older adults. Thirty community-dwelling adults aged 60 years or older with moderate stress will be randomly assigned to either an eight-session VR meditation program or a waitlist control group. Sessions last 15 minutes and occur twice weekly for four weeks, offered at home or in a hospital. Outcomes include perceived stress, anxiety, depression, sleep quality, quality of life, and mindfulness skills, measured before and after the intervention. Qualitative interviews will capture participants' experiences. The trial is registered at ClinicalTrials.gov (NCT05315609).

A course of six sub-anesthetic ketamine infusions over four weeks helped patients with treatment-resistant depression discontinue long-term benzodiazepine or z-drug use. Of 22 patients, 91% (20/22) successfully stopped all such medications by the end of the infusions, confirmed by urine tests. Fewer than 25% experienced significant worsening of anxiety, depression, sleep problems, or suicidality during withdrawal. Over a mean follow-up of one year, 64% (14/22) remained abstinent. These preliminary results suggest ketamine infusions may facilitate benzodiazepine deprescription even in patients with active depression and significant comorbidity.

In a clinical trial of ketamine combined with psychotherapy for severe treatment-resistant depression, 32 participants received six ketamine infusions with psychological support, either with or without music. Both groups showed large and sustained reductions in depression, anxiety, and suicidality at four weeks, fully maintained at eight-week follow-up. The ketamine experiences were highly emotional and mystical, comparable to those seen with psilocybin. Converging analyses suggested that mystical-like experiences contributed to the immediate and lasting antidepressant effects. Music did not enhance outcomes or psychedelic experiences.

A Canadian patient with severe, prolonged treatment-resistant depression who was actively requesting Medical Assistance in Dying (MAiD) experienced remission after a course of intravenous ketamine infusions. This is the first reported case of any intervention yielding remission in a patient who would otherwise likely have been eligible for MAiD for depression. The case raises questions about evaluating MAiD requests for psychiatric disorders, particularly regarding the definition of irremediability—whether a patient lacks any reasonable prospect for recovery. The authors suggest that a trial of ketamine warrants consideration in similar cases.

A qualitative study explored the experiences of people with advanced kidney disease who participated in the Compassionate Mindful Resilience (CMR) programme. Nineteen participants (stage 4 or 5 kidney disease or transplant recipients) took part in semi-structured interviews. Thematic analysis yielded three themes: experiences of the CMR programme that facilitated subjective benefit, participants' lived and shared experiences, and practicalities of participation. All participants reported the programme as beneficial. The CMR programme proved an acceptable intervention, providing tools that support mental health and wellbeing for this patient group.

A randomized controlled trial tested whether video-delivered Emotion Focused Mindfulness Therapy (EFMT) could reduce anxiety in adults aged 55 and older. Forty-eight participants were assigned to group EFMT via Zoom or a wait-list control. Recruitment took 32 weeks, with 62.3% of screened individuals enrolling; retention was 80.0% and adherence among the intervention group was 100.0%. At 9 weeks, the EFMT group showed a greater reduction in anxiety scores (−3.47 points) compared to the control group (−1.22 points), a statistically significant difference. The findings suggest that virtually-delivered EFMT is feasible, acceptable, and effective for late-life anxiety.

A four-week Compassionate Mindful Resilience (CMR) programme for adults with stage 4 or 5 kidney disease or a kidney transplant led to significant improvements in anxiety, depression, self-compassion, mental wellbeing, resilience, and mindfulness, with gains maintained at three months. Of 75 participants recruited, 65 completed the programme; most were female and post-transplant. All 19 interviewed participants reported benefit. The findings suggest the programme has potential to improve psychological outcomes in this population, though randomized controlled trials are needed to confirm effectiveness.

During a 10-day retreat, ten experienced meditation practitioners showed that neural dynamics can be volitionally shifted toward a critical regime—a state between order and chaos that supports flexible yet stable information processing. Compared to regular mindfulness of breathing, a refined state of meditative absorption called jhana produced pronounced sensory fading, slower respiration, higher neural signal diversity, reduced chaoticity, and enhanced mismatch negativity amplitude over frontocentral sites. Spectral analyses revealed a flatter aperiodic component and reorganization of long-range temporal correlations. These findings suggest that criticality is a candidate neurophysiological marker of absorptive, minimal-content experiences.

A proposed theoretical model suggests that mindfulness meditation training improves interpersonal relationships by increasing self-awareness, self-regulation, and prosociality, which in turn enhance the quality of interactions and socioemotional support provided to others. Better support then boosts the recipient's emotion regulation. A study protocol aims to validate this tri-process model using a multiphasic longitudinal design with 640 participants randomized into 480 dyads. The work has theoretical and social implications for developing more effective interpersonal mindfulness programs.

A pilot randomized-controlled trial tested whether Kundalini yoga could protect the aging brain. Eleven healthy older adults who had never meditated were randomly assigned to either a Kundalini yoga program or a psychoeducation comparison. Brain scans taken before and after 12 weeks showed a significant increase in right hippocampal gray matter volume only in the yoga group. The finding suggests that Kundalini yoga may have neuroprotective effects for older adults, though the small sample limits generalizability.

Late-life depression affects up to 18% of older adults and is linked to elevated dementia risk. Mindfulness-based cognitive therapy (MBCT) may help treat depressive symptoms and cognitive deficits in this population, but a definitive randomized controlled trial has not yet been conducted. This protocol describes a multi-site blinded trial comparing MBCT to an active control, a Health Enhancement Program, in 213 patients with late-life depression. Changes in depression severity, processing speed, executive functioning, and brain biomarkers will be assessed at baseline, post-intervention (8 weeks), and 26 weeks after baseline. The study will evaluate MBCT's potential to improve depression, cognitive impairments, and neurobiological markers.

Anxiety affects 6.4% of Canadian adults aged 65 and older, impairing memory and daily activities. Emotion-focused mindfulness therapy (EFMT), a meditation-based intervention that reduces anxiety in general populations, will be tested for feasibility with older adults via telehealth. This pilot randomized controlled trial will enroll 48 participants, randomly assigned to immediate EFMT or a wait-list control. Data will be collected at baseline, 8 weeks, and 16 weeks. Primary outcomes are recruitment, retention, and adherence; secondary outcomes track anxiety changes. Results will determine if a larger trial is warranted.

A brief 10-minute group mindfulness-oriented therapy was well tolerated by 92.5% of acutely hospitalized psychiatric inpatients, and 50% met stringent suitability and tolerability criteria. Among the three interventions tested, tai chi was the most suitable (76.5%) compared to body scan (35.7%) and mindful eating (22.2%). Clinical and sociodemographic factors, including gender, hospitalization length, presence of psychosis, and pre-morbid functioning, were not associated with suitability or tolerability. The findings suggest that brief mindfulness interventions, especially those with an active component like tai chi, may be suitable for this population, including those with acute psychosis.
