As a Psychiatrist who works as a consulting basis for a hospital, this is right up my alley. I would be concerned about the following:

1. Brain Aneurysm or Arteriovenous malformation (AVM) - essentially a tangle of abnormal blood vessels connecting arteries and veins in the brain) - He may have a kink in a blood vessel that doesn't allow the blood to flow as well as it should. - I would recommend that he get a Magnetic Resonance Angiography as soon as possible. In order to get this done quickly, he may need to be taken to an Emergency Room at a hospital that ideally would have the capacity to do an MRA. I've included a link to a wikipedia - This would explain most of his symptoms. https://en.wikipedia.org/wiki/Arteriovenous_malformation. .

2. Stroke - The Zeldox is an antipsychotic medication and there are reports of antipsychotic medications increasing risk of stroke in older individuals. This does not mean he should be taken him off the Zeldox, but it does increase his risk.

3. The pills for anxiety may have made him worse by reducing his blood flow to his brain further. I would recommend calling his doctor that prescribed them to ask about taking him off the anxiety meds.

4. The empty sella may be an incidental finding but it can also be a sign of the increased cerebral hypertension that would be consistent with an arteriovenous malformation. A link - https://en.wikipedia.org/wiki/Empty_sella_syndrome

I would not take him to a mental hospital until he has had an MRA done as I would fear that his symptoms would be possibly overlooked as primarily a psychiatric issue and his medical symptoms may not get their full attention. The rule in psychiatry is that medical causes of symptoms should be evaluated first before assuming it's psychiatric in nature.

I hope this is helpful and I'd be interested in knowing how things have gone.
