is Radiotherapy/Chemo 'Fog' real

Hello all,

So husband finished treatment mid February, and yesterday, to simply put it, was the most frightening time of both of our lives.

Husband woke up, went to the loo, sitting on the loo for ages, came out into the bedroom, looked out of the window, shock on his face, 'where are we', omg I was thinking what has happened to him.  He spent the best part of 30 minutes - 45 minutes in tears, trying to control his crying asking loads of questions, all he could remember was our son and myself (not even the dog).  He came downstairs and looked at our new kitchen and asked 'who fitted this' - I responded to all of the questions and was calm and patient.  It really was frightening.  I called my parents who were round within 10 minutes, my husband said 'who is this' - I said it is mum and dad, they are just popping in for a coffee - I just wanted the whole situation to be calm.  Called 111 and they arranged to get an out of hours appointment with the dr at the hospital.  So we sat down had a coffee and slowly husband started to 'come around to normal' - it did take a long while for him to get out of this 'fog' (if that is what it was).  So we went the hospital, dr asked to go to A&E to do some ecg bloods - general obs.  Everything came back ok.  I was then on facebook last night on one of the cancer forums, and I saw this thing about 'fog'.

Husband then couldn't remember the 'fog' stage, he now knows everything, but can't remember the  'fog'.

If anyone has any ideas or experiences, it would be really lovely to hear from you.

Take care y'all xx
