Brief Answer:
Consider seizures, orthostasis, TIA

Detailed Answer:
Good afternoon. As a neurologist I would primarily consider the possibility of an seizure episode since the events are paroxysmal and very short duration along with altered vocalization. Although I don't disagree with anybody who wishes to throw in a TIA (mini-stroke) I don't find the symptoms "focal" enough for my taste to qualify for a stroke. Also, strokes affecting the face usually are described as "drooping" or flattened over the lower corner of the mouth, etc. Facial grimacing is more of a seizure expression. The fact that hair stands up on his neck and temperature feels cool tells me that something is causing a large outpouring of catecholamines and this is usually on the heels of a stress or electrical burst of activity which involves the autonomic nervous system.

Of course, in such situations we need to consider what could be precipitating symptoms that are potentially seizure and what comes to mind would be dehydration, electrolyte disturbances, medication effects, ,medication interactions, sudden sodium dilution which could be caused by OVERHYDRATION, kidney failure and sudden volume increase, and less frequent but just as effective in causing sodium dilution would be patients would drink FAR TOO MUCH WATER for some reason.

I would recommend documenting his episodes....if you've got a phone video camera, have it handy to click on and start recording. If not, at least document the event as it happens including a description of what your husband was doing and what he was like BEFORE, DURING, and after the episode. Describe EVERYTHING....eye movements, neck movements, limb movements, ability to respond to specific questions, his ability to remember what happened before the event, during the event, breathing patterns......and then, take this information to your doctor for analysis or referral to your local friendly neurologist to get an opinion.

One other thing I forgot to mention but based upon his blood pressure above....I would check him for something called ORTHOSTATIC HYPOTENSION.....he may be having some type of VASOVAGAL reaction to sudden drops in pressure giving him seizure like episodes (without actual seizure activity in the brain). The way to take orthostatic pressures for something like this would be to get a BP cuff (automatic one is the best) and have him LIE quietly for 10 minutes. Take his BP and pulse. Next, STAND HIM IMMEDIATELY and retake BP AND PULSE, and then, allow him to stay standing for 2-5 minutes and again take the BP and PUSLE. Any drop of 20-30 mm. Hg. or more in the TOP number of his blood pressure or any drop of more than 12-15 beats per minute is compelling evidence for ORTHOSTATIC HYPOTENSION....due to what? No idea....but those types of drops in blood pressure could cause seizure like or if other people would like to say stroke like symptoms in your husband so I'd check it out and see what you get.

If it happens again, I would definitely urge you to call 911. At least he can get a workup started quickly in the ER even though the episode will long have passed. Somebody can see him who is a doctor and perform an examination to tell whether it was likely stroke, seizure, or something unrelated.
If your question was adequately responded to could you do me the favor of CLOSING THIS QUERY?

I sincerely hope you confer with your doctor and get a quick workup for him especially if there have been multiple episodes...this is something you do not want to wait for the "next available appointment on...."

If I've satisfactorily addressed your question then, could you do me the kindest of favors by CLOSING THIS QUERY and be sure to include some fine words of feedback and a 5 STAR rating to our transaction if you feel the response has helped you? Again, many thanks for posing your question.
