My husband is wheelchair bound and has a dementia. He is 82. I am a healthy 80 year old and his only caregiver. I alone, is responsible for all his needs including medications and meals, etc. I often wonder, what happens if I should have a seizure or any kind of fall which renders me unconscious ( God Forbid) This is always on my mind. I know I should keep a telephone near him at all times but I worry that he may forget to dial 911... This is always on my mind. I hope this never happens but I worry. Any suggestions ?
