I definitely lost cognitive function after a series of really bad episodes close together. I did get some back later. When it happened was when I went on SSDI and there is still no doubt in anyone's mind that I couldn't cognitively do my job now so it has had lasting effects but it did get better to the point I'm not as impaired as I was. I am now able to pay my bills without help, have managed to get my credit score up from horrendous to great because I pay my bills (stunning strategy I know), and generally as ok as long as there is little stress and I have help with some things like housework routinely.
