Re EEG not showing any abnormal activity: Sometime epileleptic activity hide deed withun the brain and doesn't show up on an EEG or MRI.
Have you had a 24 hour EEG where they can monitor your brain waves during your sleep ?
Or been to a sleep clinic?
I was having the same thing as you for 28 years and found this study VERY interesting.
Re Having seizures during or just before you sleep: Could be due to lack of oxygen to the brain while you sleep from sleep aids such as certain AEDs, sleeping pills, severe snoring or some sort of restriction to the airway.
I have recently been dx'd with Chronic Obstructive Sleep Apnia.
After my sleep disorders test the Dr. showed me the EEG from one night, I would stop breathing up to 50 times/hour and had 3 seizures and that I was waking up "post ictal" (moody and spaced out)
I have recently purchased a CPAP machine (Constant Positive Air Pressure) which provides constant air pressure and have noticed a vast improvement.
No more snoring (the whole family sleeps better now), more energy when I wake up, better REM sleep, improved memory (less short term memory loss), and most of all ~ NO MORE NIGHT SEIZURES.
Now maybe my Neurologist can reduce my meds.
I'm surprised that finally after 28 years I finally get an answer.
