Hello!
Thank you for asking on HCM!
I read carefully your question and understand your concern.
I would like to explain that some fluctuations may occur during recovery period.
But as you refer, he was doing well since his stroke. From the other hand an episode of confusion and speech problems raises high suspicions for a possible new small stroke (
lacunar stroke) or a
seizure.
Even a seizure, can be caused by a new stroke.
Is he taking any antiepilepsy drugs? Their overdosage could also cause a similar clinical scenario.
I recommend consulting with his GP for a careful physical examination, a brain MRI or
CT scan and some lab blood tests (
complete blood count, fasting
glucose, kidney and liver function tests, blood electrolytes, etc.), to rule in/out the possibility of a new brain ischemic event.
A brain EEG may be needed to exclude possible seizures. If he is taking any antiepileptic drug, you should measure their plasma levels (depending on the drug type).
Hope to have been helpful!
Best regards,
Dr. Iliri
