Abstract
The research included studying of total fucose (TF) and some enzymes in patients with neurological diseases such as Alzheimer's, Epilepsy and Migraine, which include of these enzymes : Fucose dehydrogenase (FDH), Glutathione S-transferase (GST) and Monoamine oxidase (MAO) were measured in the male patient group in Mosul city, Samples reached (144), which included group of male patients (97) and control group (47). The results appeared a significant decrease in TF compared with control group and increase in activity of enzymes for fucose dehydrogenase, glutathione S-transferase and monoamine oxidase in all patients with neurological diseases (Alzheimer's, Epilepsy and Migraine) compared with control group . The study showed the needed TF to perform the biological functions of the body for neurological diseases, especially with Alzheimer's disease, epilepsy and migraine, respectively. In addition to can use TF as the biochemical marker may be an indicator of neurological diseases, especially Alzheimer's disease.
