Abstract: The present invention provides protein-based biomarkers and biomarker combinations that are useful in qualifying Alzheimer's disease status in a patient. In particular, the biomarkers of this invention are useful to classify a subject sample as Alzheimer's or non-Alzheimer's dementia or normal. The biomarkers can be detected by SELDI mass spectrometry. In addition, the invention provides appropriate treatment interventions and methods for measuring response to treatment. Certain biomarkers of the invention may also be suitable for employment as radio-labeled ligands in non-invasive imaging techniques such as Positron Emission Tomography (PET).

Abstract: A method of detecting the presence, or monitoring the severity of a condition characterised by the presence of fragments of a marker protein in the brain of a patient. The method comprises: (i) providing a sample comprising macrophages obtained from the patient; and (ii) detecting the presence of the marker protein or fragments thereof in the macrophages. The presence of abnormal levels of the marker protein and/or fragments thereof in the macrophages is indicative of the presence of the condition in the patient. The condition and the marker proteins can be: Alzheimer's Disease and the Abeta peptide, Parkinson's Disease and ubiquitin, Multiple Sclerosis and myelin basic protein, FrontoTemporal Dementia and tau, Amyotrophic Lateral Sclerosis and tau, Parkinson's disease, Lewy Body dementia or Alzheimer's Disease and alpha-synuclein.

Abstract: The present invention provides a neurosecretory protein VGF peptide useful in qualifying Alzheimer's disease status in a patient. In particular, this peptide and modified forms thereof may be used to classify a subject sample as Alzheimer's disease or non-Alzheimer's disease. The peptide biomarker can be detected by SELDI mass spectrometry.

Abstract: Methods are provided for the prediction, diagnosis and differential diagnosis of Alzheimer's disease. More particularly, a method is provided to determine whether a subject that does not show any clinical signs of Alzheimer's disease has a likelihood to develop Alzheimer's disease. Further a method is provided for the diagnosis of subjects suffering from Alzheimer's disease and/or for the differential diagnosis of subjects suffering from Alzheimer's disease versus subjects suffering from other dementias such as dementia with Lewy bodies. The methods are based on the determination of the ratio of specific A? peptides.
