Abstract: The invention relates to a method to determine the Mg2+ and/or Ca2+ levels in a cerebrospinal fluid obtained from a mammal, wherein Mg2+ and/or Ca2+ levels are connected to an ?-synucleinopathy associated disease or disorder as well as a kit to be used in said method.

Abstract: A method for testing for a parietal lobe function deficiency, an occipital lobe function deficiency, and a developmental language disorder in a subject includes displaying to a subject ordered arrays of objects having features in a plurality of dimensions, which the subject is prompted to name. The named features are compared with the correct object features, and a count is maintained of errors and an interval taken to complete the naming process. These numbers are compared with predetermined data to determine possible deficiencies.

Abstract: A test, system, and method for testing parietal lobe function in a subject, wherein the method includes displaying to a subject a first ordered array of objects having a variety of colors, which the subject is prompted to name. The named object colors are compared with the correct object colors, and a count is maintained of errors in the named object colors and an interval taken by the subject to complete naming the object colors, these numbers compared with predetermined data for determining a possible parietal lobe function deficiency. An analogous test is performed of shape-naming, and, in a preferred embodiment, of color and shape naming. A practice test administration is also described, as well as a software-driven administration and scoring of the test.
