Title:	Methods of treating cognitive impairment
Abstract:	The subject invention concerns materials and methods for treating a person or animal having cognitive impairment. In one embodiment, the method comprises administering an effective amount of one or more inflammatory mediator(s), for example, fms-related tyrosine kinase 3 (Flt3) ligand, interleukin-6 (IL-6), macrophage migration inhibitory factor (MIF), interleukin-1 (IL-1), interleukin-3 (IL-3), erythropoietin (EPO), vascular endothelial growth factor A (VEGF-A), hypoxia-inducible transcription factor (HIF-1alpha), insulin like growth factor-1 (IGF-1), tumor necrosis factor (TNF), granulocyte colony-stimulating factor (G-CSF), granulocyte/macrophage colony-stimulating factor (GM-CSF), macrophage colony-stimulating factor (M-CSF), Stem Cell Factor (SCF), Darbepoetin (ARANESP), and metalloproteinases, to an animal or person in need of treatment.

Application Number:	14/145,303
Patent Claims:	1. A method for treating cognitive impairment associated with pathological amyloid beta (A.beta.) peptide accumulation in the brain of a person or animal comprising administering to the person or animal an effective amount of a granulocyte/macrophage colony-stimulating factor (GM-CSF) or an analog thereof, wherein the analog is sargramostim, and wherein the level of an A.beta. peptide is reduced in the person or animal relative to the level of A.beta. peptide in the brain of the person or animal prior to administration of the GM-CSF or analog thereof. 2. The method of claim 1, wherein the GM-CSF is administered intracranially. 3. The method of claim 1, wherein the GM-CSF is administered by intracranial infusion. 4. The method of claim 1, wherein the GM-CSF is administered by subcutaneous, intradermal, intravenous, intramuscular, intraperitoneal, or intrasternal injection. 5. The method of claim 1, wherein the GM-CSF is administered to a non-neural cell or tissue. 6. The method of claim 1, wherein said method further comprises evaluating the person or animal for cognitive impairment prior to treatment. 7. The method of claim 1, wherein the GM-CSF is administered as a composition. 8. The method of claim 7, wherein the composition comprises a physiologically or pharmaceutically acceptable carrier, diluent, or solute. 9. The method of claim 1, wherein the A.beta. peptide is a peptide designated as A.beta.peptide 1-37, A.beta. peptide 1-38, A.beta. peptide 1-39, A.beta. peptide 1-40, A.beta. peptide 1-42, A.beta. peptide 11-40, or A.beta. peptide 11-42. 10. The method of claim 1, wherein the GM-CSF is administered continuously to the person or animal over a period of time. 11. The method of claim 1, wherein the GM-CSF is administered at distinct intervals to the person or animal over a period of time. 12. The method of claim 1, wherein the GM-C SF is human GM-CSF. 13. The method of claim 1, wherein the A.beta. peptide is present as an extracellular amyloid plaque. 14. The method of claim 1, wherein said method further comprises evaluating the person or animal for cognition prior to treatment. 15. The method of claim 1, wherein the GM-CSF comprises the amino acid sequence of SEQ ID NO:1, or the GM-CSF has greater than 95% sequence identity with the amino acid sequence of SEQ ID NO:1.
