Memory When I see an adult, especially mid-40s and beyond, with fogginess and memory issues, I would look at levels of frontal alpha and look at alpha frequency distribution.  If the alpha levels in the front are relatively high–as high or higher than theta levels–then I would train them down.  If the slow alpha to fast alpha ratio is high, indicating a generalized slowing, then I would train up, say, 10-15 Hz and train down 3-5 and 8-10 Hz.  Working […]
