The ability to sleep after transplantation for remyelination may be due to the improvement of hematopoietic function, and specific cases should be analyzed. 1. The full name of remyelination is aplastic anemia, which refers to a disease in which the bone marrow has abnormal hematopoietic function leading to a decrease in whole blood cells. This disease can cause insomnia, is due to aplastic anemia patients with insufficient blood volume, can not meet the whole body’s demand for blood oxygen, if caused by insufficient blood supply and oxygen supply to the brain, it will result in a decrease in the oxygen content of the brain, insomnia, dizziness, lack of concentration and other symptoms. 2. When patients with aplastic anemia undergo bone marrow transplantation, the hematopoietic function is improved, the oxygenated hemoglobin in the peripheral blood is increased, and the oxygen supply to the brain is improved, so the quality of the patient’s sleep also improves, and the patient’s sleep is better. If the patient develops symptoms of drowsiness, or if the symptoms persist without improvement, he/she should go to the hospital for timely consultation and treatment.
