Cassidy was cited in 2014 for his 3rd DUI.
So it appears he used substances heavily until near the present.
So is his, the same type of dementia, as somebody that did not abuse substances?
Or is "dementia" a convenient non-judgmental term to use, in lieu of simply and honestly saying they drank/drugged themselves into early, mental problems?
In the case of "homeless," there is much talk of them being "mentally ill."
Again, is that a convenient non-judgmental depiction for having drank-drugged themselves into mental illness?
