I experienced sca on April 1st, 2017 (not a great April's fool). I am type 2 diabetic . I suffered from a reaction to Metformin compounded by pneumonia that caused me to be dehydrated. After renal failure at home, cardiac arrest came next. Fortunately I was already in the ER and had an excellent team looking out for me.My physical recovery has been good. My vital numbers are stabilized. However, I am experiencing issues with short time memory and other cognitive issues. Any advice on mind exercises is appreciated. I will try to share my experiences here.
