Although Alexander was aware of the scars the battlefield left on some of the men, for the time being,
he at the time had no intention of addressing it.
Mostly because there was nothing to address.
Even the people 'infected' did not think this was a disease.
But there was also the added reason that such an endeavor would drain a lot of his resources.
An agrarian society could never foot such exorbitant costs, especially at a mass scale.
And if knowledge of such effects became widespread, Alexander also feared it would hurt the recruitment efforts.
And thus Alexander decided to put a lid on it, along with all the social problems that came with it, such as the instance of soldiers on average being more abusive towards their families and having drunken fits of rage.
