Description
Galina Portnova and colleagues probe, in a 2026 study, how heart rhythm and saliva antioxidant power react to mental strain in obsessive-compulsive disorder. The links among body stress systems, chemical defense, and this illness remain murky.
Thirty-one patients and twenty-nine healthy peers did a demanding eye-movement task while heart signals and saliva were sampled before and after. Patients began with lower antioxidant capacity and failed to raise it under load, unlike controls. Splitting patients by resting heart rate revealed a sharper split: the low-rate subgroup lost antioxidant ground and showed stress-system overdrive, while the high-rate subgroup coped like controls. Resting heart rate may flag a harder-hit body subtype of the disorder.
