Hi rexpac,

Welcome to the forum! I'm no neuro but I've had absence and complex partial sz. for over 30 yrs. and what you are describing sounds like your wife may be having complex partial sz. Ask your wife the following questions:
Does she see colors flashing back and forth in her eyes?
Does she get a nervous feeling in her stomach or smell odd odour before she blanks out?
Does she hear one word repeated over and over again and during all of this time she's still conscious?
Have you noticed her smacking her lips, or pulling at her clothes and then wandering around? If you or your wife have seen or felt any of these things this is a complex partial sz. and I've found taking vimpat the best thing for my sz. Since I was put on vimpat I've only had 1 complex partial sz. this yr.
In regards to the time of your wifes sz. I often will have either an absence or complex partial sz. early in the morning or later in the afternoon on certain days of the month. This could all be hormone related or if there's a low pressure in the weather that can sometime trigger sz for people.
I wish you and your wife only the best and May God Bless You Both!

Sue
