There is no urine or blood test for diagnosing Alzheimer's. Further complicating matters, several other dementias and diseases exhibit similar symptoms, especially in beginning stages.
Doctors must work through a process of elimination. When they eliminate other possible causes for symptoms, and reach the full criteria for Alzheimer's, they make a diagnosis. However, it might take a while to reach a correct diagnosis.
Neurologists conduct the following tests and examinations when diagnosing Alzheimer's.
