Off-label Use of Lamotrigine and Naltrexone in the Treatment of Ketamine Use Disorder: A Case Report.
Journal of addiction medicine
Summary
A promising treatment breakthrough emerges for ketamine addiction: combining two existing medications - lamotrigine and naltrexone - helped a patient overcome severe cravings and achieve sustained recovery. The medications reduced hallucinogenic effects, triggered nausea when using ketamine, and decreased cravings. When paired with therapy and support groups, this novel approach offers hope for treating ketamine dependency.

Mapping the Use of Ketamine in Treatment-Resistant Depression and Other Psychiatric Disorders: A Scoping Review of Practice Patterns, Efficacy, and Patient Demographic Trends.
American journal of therapeutics
Summary
Ketamine therapy shows promising results for patients who don't respond to traditional depression treatments, with success rates reaching 70% in some cases. This comprehensive analysis of treatment patterns reveals that IV administration remains the preferred method, though accessibility varies widely. Private clinics offer more flexible psychiatric care than hospitals, but health care accessibility remains a challenge, especially in rural areas. Most patients are middle-aged, and insurance coverage limitations create financial barriers to this innovative treatment option.

Ketamine's Altered States Meta-Analysis: The Relationship Between Psychomimetic and Clinical Effects With Focus in Depression.
Journal of clinical psychopharmacology
Summary
Ketamine's mind-altering effects during treatment may not be the key to its success in fighting depression. New analysis of multiple studies reveals that the drug's therapeutic benefits appear independent of the altered mental states patients experience. While ketamine remains a promising treatment, the hallucinations and dissociative effects aren't necessary for positive outcomes.

Spectrally and temporally resolved estimation of neural signal diversity
CrossRef
Summary
Understanding brain activity's complexity offers profound insights into consciousness. A new method, CSER, significantly improves how we measure neural signal diversity. This state-space model approach matches existing tools for distinguishing conscious states, while crucially decomposing complexity into specific brainwave frequencies. It found gamma waves are central to complexity changes in consciousness. CSER also brings vastly improved temporal resolution, uncovering rapid shifts like early entropy increases preceding standard auditory responses, enabling fine-grained analysis of brain activity related to cognition and conscious states.

Accurate and Interpretable Prediction of Antidepressant Treatment Response from Receptor-informed Neuroimaging
CrossRef
Summary
Predicting individual depression treatment response is challenging. New predictive tools, using pre-treatment brain imaging and clinical data, accurately forecast antidepressant response in major depressive disorder. This advanced approach achieved strong accuracy, identifying biomarkers tied to better outcomes in serotonin systems. Comparing psychedelic-assisted therapy with psilocybin and escitalopram, psilocybin showed a group-level advantage. It also pinpointed specific brain profiles suggesting who would benefit more from escitalopram, enhancing treatment selection. This advances precision medicine and biomarker discovery, enabling more personalized care.

Modulation of event-related potentials of visual discrimination by meditation training and sustained attention
CrossRef
Summary
Did you know mental training can sharpen your visual focus? Research reveals that meditation practice significantly enhances the brain's ability to discriminate visual stimuli and sustain attention. When participants engaged in meditation while facing a consistent visual task, their brain activity showed improved early sensory processing. This indicates that developing perceptual capacity beyond a task's demands positively impacts attentional control and visual processing.

Cognitive Aging and Long-Term Maintenance of Attentional Improvements Following Meditation Training
CrossRef
Summary
Remarkably, intensive meditation training can help preserve sharp focus for years, even as we age. Researchers explored if dedicated mental practice could offer lasting benefits against age-related cognitive decline. Following a 3-month full-time meditation program, participants' attentional improvements were partially maintained up to seven years later. Crucially, continued meditation practice significantly moderated typical age-related declines in sustained attention and response inhibition. This suggests that ongoing mental training has the potential to positively alter long-term cognitive trajectories, offering enduring benefits for brain health across the lifespan.
Abstract
Sustained attention is effortful, demanding, and subject to limitations associated with age-related cognitive decline. Researchers have sought to e...
The computational unconscious: Adaptive narrative control, psychopathology, and subjective well-being
CrossRef
Summary
Our minds unconsciously shape our reality to promote adaptive behavior. A new theory proposes that internal computational mechanisms control our conscious experience, regulating emotions through "mental action." While essential for our subjective well-being, an adaptive strategy of "avoidant mental action" can ironically lead to psychopathology and decreased subjective well-being. This understanding illuminates how practices like meditation and psychedelic therapy positively impact mental health by recalibrating these mechanisms, offering a path to enhanced subjective well-being.

Executive control and felt concentrative engagement following intensive meditation training
CrossRef
Summary
Intensive meditation training significantly boosts mental focus and control. A recent investigation found that one month of daily Vipassana meditation enhanced participants' ability to inhibit responses and reduced their reaction time variability on a challenging task. Crucially, they also reported higher levels of concentration, which directly correlated with improved attentional stability. This suggests that meditation not only sharpens cognitive abilities but also cultivates a clearer, more stable sense of engagement, validating the subjective experience of enhanced focus.

Ketamine Cystitis in a Female Patient Ketamine Therapy for Treatment Resistant Depression – Case Report
CrossRef
Summary
A significant safety concern has emerged for therapeutic ketamine, a promising antidepressant for treatment-resistant depression. While ulcerative cystitis, causing painful urinary symptoms and kidney damage, affects over 25% of recreational users, it was previously unreported in medical settings. The first documented case now links therapeutic ketamine use to this severe condition. A 28-year-old woman developed confirmed cystitis symptoms after starting ketamine for depression. This highlights a crucial safety consideration, emphasizing that early detection and stopping treatment are vital to prevent further harm.

Summary
A single dose of DMT led to 57% of major depressive disorder patients experiencing remission 12 weeks later. This naturally-occurring psychedelic, also found in ayahuasca, shows significant promise. A separate trial found ayahuasca caused remission in 36% of patients with treatment-resistant depression within one week. While generally safe, ayahuasca can cause transient vomiting. The therapeutic and biological roles of DMT, including its possible link to near-death experiences and its impact on human consciousness, warrant further exploration.

Summary
At-home subcutaneous ketamine significantly reduces symptoms of depression, anxiety, and PTSD. Among 3,870 patients, 81.8% with depression, 80% with anxiety, and 84.6% with PTSD achieved clinically meaningful improvement after six weeks. Depression scores dropped from 14.64 to 6.30, anxiety from 13.06 to 6.09, and PTSD from 46.7 to 27.5, demonstrating large effect sizes (1.35-1.58).

Turn on, Tune in, and Drop out: Predictors of Attrition in a Prospective Observational Cohort Study on Psychedelic Use (Preprint)
CrossRef
Summary
Concerns about bias in online psychedelic research may be overstated. A prospective investigation of 654 participants found that demographic factors like age and education, alongside personality traits such as conscientiousness and extraversion, predict who completes follow-up surveys. Significantly, neither initial enthusiasm for psychedelics nor challenging experiences influenced dropout rates. This suggests that data gathered from naturalistic psychedelic use is more robust and less prone to certain biases than previously thought, strengthening the field's insights.
