Hi,
The medication advised for the seizures, were causing any sort of discomfort from that time (Nov 2013)?
If the problem is recent, then drugs might not be the cause. However, for
epilepsy, drugs dosage reduction is usually done after two seizure free years.
If he has breathing problems, exact type and cause needs to be understood. If you give me more details, I will try to find out and explain or else meet your physician once.
Sleeping most of the time, might be due to disturbed sleep in the night. Maybe he needs to be evaluated for any
sleep apnoea syndrome. Do check if he is sleepless at night, if yes, problem needs to be addressed. If not, a thyroid profile might be necessary to rule out
hypothyroidism.
If you have any further queries, happy to help again.
