I am retired nurse and can only urge that every one get a copy of the Hospitalization of a Parkisons Patient and it addition learn as much as you can about any other condition you may have. Medical and Nursing education cannot give all practitioners all knowledge. Most try hard to keep up, but an educated patient is a joy to have. All I can say is , if you are not getting good care in a hospital you should call or ask for the supervisor to resolve any problems. I have my husband stay with me in the hospital every time he can. I learn what my medications are and what they look like. I have a great advantage because I am familiar with medical terms, but I do not hesitate to question and question. One thing is that I have an unusual heart condition and my husband has PD. We watch each other. You do not have to be any kind of caregiver to learn a great deal about what you or your loved one may have. For instance, the last time I was hospitalized was for an unrelated type of surgery. There was a mix up about my cardiac medicine, It wound up that the pharmacist (hospital ) came to ask me personally. You cannot learn everything a specialist in your condition knows but you can learn a lot. Your own experience tells you a lot. I would be very happy if both of us were healthy, but we are not. So we have to deal with it. Thanks , Nita
