Hello!
Thank you for asking on HCM!
I understand your concern and would explain that his symptoms don't seem to be cardiac related.
I would recommend consulting with a
neurologist for a careful physical examination, some lab blood tests (
complete blood count, PCR, sedimentation rate,
thyroid hormone levels, fasting
glucose, kidney and liver function tests, blood electrolytes,etc.).
A brain EEG is needed to rule in/out possible partial seizures, which could mimic this symptomatology. (Although the duration of the symptoms is not very typical for seizures).
If the EEG results normal, it should be followed by a brain
CT scan or MRI, to exclude a possible intracranial lesion.
Hope to have been helpful!
Feel free to ask any other questions, whenever you need!
Greetings!
Dr. Iliri
