Hi @fekind,
This must be so stressful for you and your fiancé. I'm bringing @soitis4590 @IndianaScott @chesneydell1965 @carer into this conversation about stroke. They have all had experience with stroke as a patient or caregiver. I wonder if they have had any experience with increased appetite after stroke.

Fekind, did your partner work with a stroke rehab team? http://www.mayoclinic.org/diseases-conditions/stroke/in-depth/stroke-rehabilitation/art-20045172
