1. A method of detecting and diagnosing neural injury and/or neuronal disorders comprising: detecting at least one or more protein biomarkers in a subject sample, and; correlating the detection of one or more protein biomarkers with a diagnosis of neural injury and/or neuronal disorders, wherein the correlation takes into account the detection of one or more biomarker in each diagnosis, as compared to normal subjects wherein the one or more protein markers are selected from: axonal proteins, amyloid precursor proteins, dendritic proteins, somal proteins, presynaptic proteins, post-synaptic proteins, demyelination biomarkers, glial proteins, neurotransmitter biomarkers, dopaminergic proteins, noradrenergic proteins, serotonergic proteins, glutamatergic proteins, GABAergic proteins, neurotransmitter receptors, neurotransmitter transporters, vimentin (P31000), CK-BB (P07335), 14-3-3-epsilon (P42655), MMP2, MMP9 and; correlating the detection of one or more protein biomarkers with a diagnosis of neural injury and/or neuronal disorders, wherein the correlation takes into account the detection of one or more protein biomarkers in each diagnosis, as compared to normal subjects.
