A 2026 serum multiomics study linked occupational noise exposure to tinnitus severity mostly through metabolism: 10 metabolites, including GABA, fumaric acid, and steroid hormone precursors, statistically mediated 92% of the exposure-tinnitus association.1 The result is not a clinical blood test yet, but it pushes tinnitus biology beyond the ear-only frame toward a metabolism-immunity model that …
A 2026 medRxiv preprint did not find one simple autism excitation-inhibition signature. Bertelsen et al. found 2 EEG-derived E:I neurosubtypes in 286 autistic males: a 47% inhibition-dominant subtype with higher Hurst exponent and lower gamma, and a 53% excitation-dominant subtype with the opposite pattern.1 Research Highlights Two subtypes, opposite directions: in 286 autistic males ages …
Zuranolone, a novel antidepressant, shows promise in treating depression, as evidenced by a recent meta-analysis. A new study investigated zuranolone’s efficacy and safety, focusing on short-term rapid antidepressant effects. Highlights: Zuranolone Effectiveness: Demonstrated significant improvement in depression severity scores compared to placebo, with notable effects by day 15. Treatment-Emergent Adverse Events (TEAEs): Increased incidence in …
Allopregnanolone agonists represent a promising new class of medications for treating depressive disorders. Evidence suggests that allopregnanolone agonists exhibit rapid-onset of antidepressant action – particularly in women with postpartum depression (PPD). Key facts: Allopregnanolone is a neurosteroid that acts as a positive allosteric modulator of GABAA receptors and is decreased in depressive disorders. The allopregnanolone …
Xanax (alprazolam) is a drug of the benzodiazepine class originally developed by Upjohn, a Michigan-based pharmaceutical company (now a subsidiary of Pfizer). In the United States, Xanax first received FDA approval for the treatment of panic disorder and hit the market as a prescription medication in 1981. It eventually received subsequent FDA approval for the …
Gabapentin is rumored to have been synthesized by chemists in the 1970s in attempt to develop an antispasmodic agent. After its synthesis, rights to gabapentin were acquired by Parke-Davis (a subsidiary of Pfizer) whereafter it underwent clinical trials that evaluated its safety and anticonvulsant efficacy in the treatment of seizures. Clinical trial data indicated that …
Baclofen is a drug that was originally synthesized in the early 1960s by Heinrich Keberle, a Swiss chemist employed by the pharmaceutical company Ciba-Geigy. At the time of its synthesis, Keberle hypothesized that baclofen would prove effective as an antiepileptic agent, however, clinical trials yielded unfavorable results. Though ineffective as an antiepileptic, researchers noticed that …
