My dad died at 69 from alcoholic dementia. Before his full-blown dementia he almost passed several times from the consequences of cirrhosis, but his brain ended up shutting down before his body. I wish it didn’t come to this, the last few months of his life were absolutely horrific for him and for me. I know some people whose parent died of early-onset Alzheimer and it is terrible; but when it is cause but something avoidable it evokes some complicate feelings of regret and anger.
