What Causes Easy Bruising Along With Fatigue And Shortness Of Breath?

My daughter s doctor, at first thought that she possibly had leukemia, but now thinks it is related to medications. My daughter is 57 years old, has Down Syndrome, Osteoarthritis, Alzheimer s, and depression. Her medications are Aricept, Namenda, Cymbalta, Prilosec, Tylenol, Vitamins, and a few that I can t remember. She lives in a tenant support program and I don t have access to her medications at this time. She also has sleep apnea. She was taking a protein powder but was taken off that due to weight gain. She does not exercise. After she stopped the protein powder she lost a considerable amount of weight in a relatively short time. Could stopping the protein be responsible for this? She is also having easy bruising, fatigue, shortness of breath. Her blood test came back normal. Is there anything else that could be causing her problems?
