Weekly "brain fog/cognitive impairment" episodes lasting 20-30 seconds

Hello all,

Ever since my return from an international trip to China (with a group of over 50 people), I have been experiencing episodes of "brain fog" once every 4-9 days, for the past 5 months. FYI: Nobody else, that I know of, on the same trip are experiencing any unusual symptoms, for what it's worth.

My "brain fog" symptoms:

- Occurs once every 4-9 days, has occured twice in one day on 4 occaisions.
- Short lasting (10-30 seconds), sudden onset of "cognitive impairment"... as though my IQ drops from normal to 50. I have a very hard time comprehending what's being said or focusing during the episode.
- A very slight "aura" .... a feeling that it is about to happen lasting 2-3 seconds before the "brain fart".
- Sudden onset regardless of situation, what I've eaten, where I am, time of day, level of stress, etc.
- No other parts of body are affected. No twitching, flushed feeling, headache, changes in breathing, hearing or vision, etc. etc. etc. really only a temporary "cognitive impairment" where I have a very hard time focusing on what is currently going on or being said. For instance, I was able to drive a car while it occured, but couldn't hold a conversation.
- I am still aware of my surroundings... but don't really have the brainpower to focus on anything.
- I sometimes feel a little tired/discouraged and "off" for about 20-30 minutes after the episode.

An example of a task I tried to complete during an episode, within about 5 seconds of onset: I like to track episodes in my iPhone calendar... Tried during an episode and ended up going into "phone" instead of "calendar", looking for a place to enter the time and date of episode. Within another 10 seconds or so, I suddenly realize that I'm not in the right place... And slowly make my way to the calendar. Weird.

I've had a blood test, CT scan, and EEG as well as some routine in-person tests by a neurologist. Nothing found.

I have looked into MS and multiple seizure types, but they don't seem to fit. Symptoms are really limited to temporary brain/cognitive fog/impairment - NOTHING more (nothing obvious).

Please help!!!

Thank you much!
