Ketamine Reshapes Neural Networks and Neuroplasticity

Ketamine triggers a corticosterone-FKBP51 signaling pathway in female mice that prompts microglia to clear extracellular matrix and enhance synaptic plasticity, an immune-driven mechanism absent in males.

Buprenorphin and Ketamine Combo Provide Anti-Suicidal Effect

A sequential combination of a single ketamine infusion followed by four weeks of low-dose daily buprenorphine successfully extends the antisuicidal window of ketamine from one fleeting week to over a month.

How Scientists Cracked the Ketamine Code for Depression

By "reverse engineering" ketamine, Weill Cornell investigators have identified a specific opioid receptor pathway and a unique receptor "cross-talk" that drives rapid antidepressant effects.

Blocking NOX-1 Extends Ketamine’s Effectiveness for Depression

Researchers have identified the NOX-1 enzyme as the reason ketamine's antidepressant effects are short-lived. By blocking NOX-1, they extended the drug's benefits from days to weeks.

This shows PET scan images of the brain in response to ketamine.

Ketamine Fails to Outperform Placebo in Major Depression Trial

A large randomized and blinded clinical trial has found no additional benefit of repeated ketamine infusions over standard inpatient care for treating major depression. The study compared ketamine with a psychoactive placebo and found no meaningful differences in objective or self-reported depression scores, cognition, or quality of life.

Ketamine Plus Therapy Offers Lasting Relief for Severe Depression

A first-of-its-kind clinical trial shows that ketamine treatment for severe, treatment-resistant depression is significantly more effective when paired with psychotherapy and supportive environments. Patients who underwent this combined treatment reported a 30% drop in depression symptoms, with reduced anxiety and suicidal thoughts lasting at least eight weeks.

Boosting Ketamine’s Antidepressant Effects to Last Two Months

Ketamine is a fast-acting antidepressant that can relieve symptoms of major depressive disorder (MDD) within hours, even in treatment-resistant cases. However, its effects typically last only a week, and frequent dosing poses risks like dissociation or addiction.

Brain Wave Phase Locking May Be Key to Unconsciousness

Despite acting through different molecular mechanisms, ketamine and dexmedetomidine both disrupt brain wave phase alignment in ways that reliably induce unconsciousness. A new study reveals that these anesthetics trigger a common signature: increased phase locking at low frequencies, particularly between brain hemispheres, while disrupting local cortical communication.

Ketamine’s Hidden Physical and Psychological Damage

A new study highlights the severe physical and psychological consequences linked to ketamine addiction, with many users unaware of the risks until dependent. Researchers found high rates of bladder damage, painful organ cramps, low mood, and anxiety among those with ketamine use disorder.
