Abstract
This invention is directed to systems and methods for analyzing depression, and more particularly relates to systems and methods for analyzing and assessing depression and mood disorders in an individual using electroencephalographic measurements. Embodiments of the invention are not limited to depression, but can also include other mood disorders such as bipolar disorder and other disorders with at least one genetic-related component.
Claims6
A computer operable method for analyzing and assessing a mood disorder in a person, comprising:
- receiving, in the computer, electroencephalography data associated with the person, the electroencephalography data including at least one static component corresponding to a baseline level of behavioral functioning of the person and including at least one dynamic component corresponding to an acute level of behavioral expression of the person;
- determining, by operation of the computer, the static component of a portion of the electroencephalography data, wherein the static component is independent of the dynamic component included in the electroencephalography data;
- determining, by operation of the computer, the dynamic component of the electroencephalography data, wherein the dynamic component is independent of the static component included in the electroencephalography data;
- determining, by operation of the computer, a static asymmetry in the static component, wherein the static asymmetry is determined by computing an intersection between a left spectral pattern of the static component and a right spectral pattern of the static component and by removing the intersection from the left and right spectral patterns of the static component;
- and
- determining, by operation of the computer, a dynamic asymmetry in the dynamic component, wherein the dynamic asymmetry is determined by computing an intersection between a left spectral pattern of the dynamic component and a right spectral pattern of the dynamic component and by removing the intersection from the left and right spectral patterns of the dynamic component;
- and
- based at least in part on the static asymmetry in the static component and the dynamic asymmetry in the dynamic component, determining, by operation of the computer, an indication for whether the person is at risk for the mood disorder,
- wherein the mood disorder comprises at least one of the following:
- depression, bipolar disorder, or a disorder with at least one genetic-related component.
