I know pretty well what you're talking about, except that stroke or cerebrovascular accident (CVA) are very specific to loss of brain function caused by a blocked artery (ischemic) or a ruptured blood vessel (hemorrhagic), which can't even be cogitated about without having available McCasland's actual medical issue report.
We're likely not going to get his medical records, those are private. Prior to his wife's statement, the information available stated a Silver Alert had been issued. The state guidelines make it clear that a Silver Alert is issued when:

...the reporting party only needs to indicate they believe the missing person shows signs or symptoms of Alzheimer's disease or other forms of dementia, cognitive decline or impairment, regardless of age.
Reading that a Silver Alert was issued for McCasland, it would indicate the reporting party believed there was some sort of cognitive impairment. That's what triggers a Silver Alert.
If, as Todd's post suggests, he was in good mental health very recently, but is now the subject of a Silver Alert indicating cognitive impairment, a stroke is a reasonable suggestion. They can happen very fast and leave healthy person with physical and cognitive impairments within hours. The impairments can be temporary, permanent or a combination.
The problem is we have the wife saying that while he has some sort of "risk", it's not some form of mental decline. This is contradictory to the New Mexico state guidelines for issuing a Silver Alert. So, we have a conundrum. If McCasland has NO cognitive impairment, then why was a Silver Alert issued?
It's possible the guidelines are just that, guidelines and not hard rules. The local Sheriff may have the authority to issue a Silver Alert for risk issues outside of cognitive impairment and decline. Such as, a missing person that is known to be acutely diabetic and relies on daily insulin therapy or someone in need of weekly dialysis or any other medical condition that requires regular care in a timely manner.
