My heart goes out to the elderly person suffering from migraines. My mother had suffered from Parkinson’s disease and we hired a home care provider from an agency named C-care which is nearby. It's an extremely stressful, physically taxing, mentally and emotionally challenging full-time JOB that goes on 24 hours a day 7 days a week and 365 days a year. Only those who have undergone through this will understand. I hope a cure can be found soon. My suggestion would be to call a reputed home care service-find out the help they provide and get the support from them.
