I was misdiagnosed and have been fighting Lyme, Babesia and Bartonella for 19 years. I nursed both my children and gave it to them also. I almost died but I was lucky enough to be diagnosed properly at the last minute and have been in treatment on and off for ten years.
Thank you for writing about tick-borne illnesses. Unfortunately, the CDC and other groups such as the IDSA have done much damage to the issue of patient care and the testing, diagnosis and treatment has been a debaucle. These doctor groups have known about ticke-borne illnesses for a long time and have put politics before patients. I’d encourage you to look deeper into the politics and corruption that has made being a patient in both the USA and Canada a nightmare. Please contact other groups like or for information that Lyme literate doctors and researchers have been putting out for two decades and which groups like the CDC and IDSA have ignored. Those studies are out of respected universities like Stanford and Harvard, along with a multitude of articles from respected medical journals. The politics of Lyme would be a great next book for you I think. You’ll be amazed at what you find once you start digging. The movie ‘Under Our Skin’ is a good place to start. Thank you for writing about this issue that has affected my family for so long and I do hope you follow up.
The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression".   Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible.  The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game.  Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males.
