No, its always been there. On my IQ test in 2001 I scored extremely low on the performance part because of it, there was a 41 pt spread between my verbal and performance scores.

I was doing a lot of research on cognitve impairment associated with bipolar a couple of weeks ago and came across this "in euthymic patients an increase in amplitude of waves was found onEEG especially in brain areas associated with visuospatial processing deficits" .

Not entirely sure what all that means exactly, an increase in activity in those areas making it work better during stable times? The visualspatial processing deficit wording is what stood out in that piece.

Anyway, it made me curious. And yeah, lots of folks can't parallel park a car LOL
