Electrohypersensitivity as a Newly Identified and Characterized Neurologic Pathological Disorder: How to Diagnose, Treat, and Prevent It

March 17, 2020
Abstract Since 2009, we built up a database which presently includes more than 2000 electrohypersensitivity (EHS) and/or multiple chemical sensitivity (MCS) self-reported cases. This database shows that EHS is associated in 30% of the cases with MCS, and that MCS precedes the occurrence of EHS in 37% of these EHS/MCS-associated cases. EHS and MCS can...

Saliva cortisol, melatonin levels and circadian rhythm alterations in Chinese primary school children with dyslexia

February 9, 2020
RESEARCH ARTICLE: OBSERVATIONAL STUDY Medicine: February 2020 – Volume 99 – Issue 6 – p e19098 doi: 10.1097/MD.0000000000019098 Abstract Cortisol is the main end product of hypothalamic-pituitary-adrenal gland (HPA axis), and melatonin (MT) has a regulating effect on HPA axis, and both are closely related to individual behavior and cognitive function. We aimed to evaluate cortisol and MT roles on children dyslexia in...

Wi-Fi decreases melatonin protective effect and increases hippocampal neuronal damage in pentylenetetrazole induced model seizures in rats.

December 12, 2019
Pathophysiology. 2019 Nov 21. pii: S0928-4680(19)30043-4. doi: 10.1016/j.pathophys.2019.11.003. [Epub ahead of print] Abstract AIM: Epilepsy is a common brain disorder in which the seizures could cause a neuronal loss in the hippocampus. Oxidative stress has an important role in the pathology of epilepsy. Some studies indicate that Wi-Fi increases oxidative stress and suppresses antioxidant systems. The aim...

Can artificial light ruin your sex life?

October 10, 2019
Melatonin controls your circadian rhythms, including your sex steroid hormones. Artificial light can suppress melatonin and disrupt these rhythms! Sasseville, A., Paquet, N., Sevigny, J., & Hebert, M. (2006). Blue blocker glasses impede the capacity of bright light to suppress melatonin production. Journal of Pineal Research, 41(1), 73–78. https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1600-079X.2006.00332.x Artificial light at night: melatonin as a...
