Hi! According to the description of symptoms , your husband appears to have 'Simple Partial Seizures'
I would suggest you to have consultation with an eminent neurologist
& undergo investigations like EEG & PET MRI
You need not worry much because the problem may be cured completely, but may require a long term treatment & to be under observation of the neurologist. He may also require cognitive behavioral treatment.
Thanks & take care of yourselves.
