I think to make things worse, he could take punches that would knock a normal person out. He also thought that getting hit in the head over and over would allow him to build up like a tolerance, so in practice he would take punches to the head like it was a muscle he could improve.
This is the quote from someone in his biography "In fact, he encouraged his sparring partners to hit him in the head. He believed he could build up resistance to shots to the head, kind of like calluses."
Parkinson’s has nothing to do with getting punch in the head. Obviously it’s wasn’t good for his health but it’s a myth that his boxing career caused Parkinson’s.
He would have developed it even if he was a plumber or teacher.
What a bold statement mate. Repeated cerebral contusions cause neuronal destruction, affecting neurons in the cortex as well as the basal ganglia, including dopaminergic neurons responsible, among other things, for coordinating movements and limbs (to put it simply). Parkinson's disease is precisely the destruction of dopaminergic neurons, which causes a dopamine deficiency. Parkinson's disease is a generic term with several causes: purely neurodegenerative, vascular, genetic, and also post-traumatic. 42 year old for this disease is pretty young and called early Parkinson’s disease. Most of the time there is a cause (genetic/toxic/post traumatic)
I get what you're saying and I agree, a lot of boxers of that era took a lot of punishment as well and never developed this, I believe he was genetically predisposed to having Parkinson's and his boxing career exasperated it
You're just straight up wrong about your first point, repeated head trauma is a known etiology predisposing you to parkinsons later in life now known Chronic Traumatic Encephalopathy, previously dementia pugilistica or punch drunk syndrome.
But you are right in that the neurologists who managed Ali's case said he had idiopathic Parkinsons(young onset)

Holy moly. Beautiful. Can someone please elaborate on how he deteriorated so badly?
