You may want to also suggest to Tex that he get his father's consent to release medical information to Tex. With the HIPPA laws, even sympathetic physicians are unable to discuss medical information with family members. And Dad may not remember, or be willing, to share the information on his own. The same goes for insurance companies, if Dad has private insurance.
An aside question, from one in a similar situation: Would it be possible for Tex to move to Florida? Some concerns that I have seen are things like forgetting that something is turned on (the stove, the bathtub, etc.), phishing phone calls, and other problems associated with aging.
Bankers deal with seniors all the time and we are often powerless to step in, even when we see potential problems unfolding before our eyes. I can remember clearly an elderly lady who would come into the bank every day and cry because she didn't understand the mail that had been sent to her house. We would go over everything with her every day, but were powerless to stop her when she "lent" a substantial amount of money to her "caretakers." who, of course, ripped her off.
It is a hard situation, and I sympathize with Tex. The sugestions already posted are a good start. Thank you for being a concerned friend.
