@santosha Chris, yes you are absolutely right. No warnings, no focal seizures. I had various tests done and went to the professor of neurology at the University of PA Hospital (1975) only to get shrugged shoulders. Clear brain scans. Forty years later, I did develop peripheral neuropathy in 2014 and given an affirmative dx in 2015. Idiopathic sensory motor peripheral neuropathy, again, shrugged shoulders at Mayo in MN in 2020. So, bottom line, I've been dealing with neurological issues for 55 years. Over the years, I've learned to live my life the best I can, take meds and I realize that I am fortunate that the Dilantin is holding me seizure free.
