Hi welcome to H.C.M.Forum. the condition appears to be convulsions, most probably parietal sesures, or rheumatic sesures. i advise you to consult a neurologist
for diagnosis. he may have to get the EEG, CTscan, and other blood tests necesory to confirm the diagnosis. underlying cause might be hypertension
etc. i advise you to avoid tobacco& alcohol in access. and some drugs like antihistamines, fluroquinolone antibiotics, & central nervous system
stimulants like caffine, tramadol etc.
dont worry he willbe fine soon. restrictions are for ever.
