A 2026 neuroscience review argues that chemotherapy-induced peripheral neurotoxicity should not be treated as a purely peripheral nerve problem: CIPN affects 70-90% of patients during chemotherapy, persists chronically in 20-30% of survivors, and may interact with central sensitization, pain networks, mood, sleep, and chemobrain.1 The strongest claim is mechanistic connection, not proof that neuropathy alone …
A 40-rat early-life visceral stress study found auditory pathway sensitization without hearing-threshold loss: neonatal colorectal distension produced IBS-like visceral hypersensitivity, normal ABR thresholds, shortened auditory brainstem latencies, increased amplitudes, and 219 differentially expressed cochlear proteins.1 The result turns IBS-like stress exposure into a gut-pain and sensory-processing question. Research Highlights Visceral hypersensitivity was strong: At 20 …
A 2026 targeted metabolomics study of knee osteoarthritis found 33 altered serum metabolites and 10 altered cerebrospinal-fluid metabolites, but the symptom signal split by compartment: serum amino acids, bile acids, and acylcarnitines tracked pain or fatigue, while CSF histamine and 3-hydroxyphenylacetic acid tracked central pain and sleep measures.1 Research Highlights 33 serum metabolites shifted: knee …
A 2026 Taiwanese case series reported VAS pain drops in all 3 adults treated with pregabalin for type I complex regional pain syndrome: 9 to 5, 2 to 1, and 6 to 3 after doses of 75-150 mg/day. The signal is clinically interesting because pain relief helped rehabilitation participation, but the evidence remains weak because …
