Is there a difference and if not, can ex boxers such as Meldrick Taylor (cannot post links yet but search for Chavez VS Taylor HBO Legendary Nights on youtube, watch all three parts or skip to part 3 to see how he is now) be treated with processes such as LENS?

If not, why?

Also, and this may be a bit of an stupid question, but what about actual dementia and its differences to PCS and/or chronic boxer’s encephalopathy? Are symptoms of dementia just similar to some cognitive effects of PCS, but the root cause inside the brain is different?

Gets a bit unclear since head injury is linked with dementia and the symptoms being similar in some cases.

Apologies for the negative topic and if I've asked any ignorant questions.
