  • Patent number: 8894973
    Abstract: The invention is a method for the differential diagnosis of chronic schizophrenia or chronic alcoholism, by imaging the brain of a subject to detect any or all of the markers phosphocreatine (PCr), N-acetyl aspartate divided by the total creatine signal (NA/Crt), and synaptic phosphodiester (sPDE), and determining any increase or decrease in the presence of such markers compared to normal levels in specified anatomic areas of the brain. The output of such a method, resulting from such imaging, is presented to be viewed by a diagnostician in order to support the differential diagnosis based on the data output.

  • Publication number: 20130211227
    Abstract: Biomarker diagnosis of chronic schizophrenia in the presence of cognitive impairment is confirmed when Phosphocreatine (PCr) levels are increased, compared to normal levels, in both the left and right prefrontal cortices of the brain, with increased PCr specifically also in the left basal ganglia and also reduced NA/Crt in the left superior temporal region of the brain. Biomarker differential diagnosis is also taught for chronic alcoholism (with or without cognitive impairment) and for chronic schizophrenia even when cognitive impairment is absent.

  • Patent number: 8329142
    Abstract: Compounds, compositions and methods for the detection and diagnosis of Parkinson's disease. Derivative lycerophosphocholine (GPC) compounds are used as a detection and diagnostic aid to measure progression of Parkinson's disease by detecting GPC binding to ?-synuclein. Derivative CPG compounds including non-radioactive, paramagnetic, and radioactive derivatives of GPC are presented. These compounds possess similar binding properties to original GPC molecules and are useful in medical magnetic resonance imaging (MRI) and/or positron emission tomography (PET) applications. By employing these radiological techniques in conjunction with the compositions of the present invention, the detection, diagnosis and assessment of the progression of Parkinson's disease may be achieved.

Compounds including non-radioactive, paramagnetic, and radioactive derivatives of GPC are presented. These compounds possess similar binding properties to original GPC molecules and are useful in medical magnetic resonance imaging and/or positron emission tomography applications. By employing these radiological techniques in conjunction with the compositions of the present invention, the diagnosis and assessment of the progression of Alzheimer's disease may be achieved.

  • Patent number: 7700074
    Abstract: Chronic alcoholism is a diverse and heterogeneous disorder that can be dichotomized into cognitively intact and cognitively impaired subgroups. At a molecular level, ethanol has been shown to have both acute and chronic effects on: Membrane biophysical properties, Membrane composition and metabolism, Protein phosphorylation, Lipid metabolic signaling, Lipoprotein transport of cholesterol. Actual molecular underpinnings are determined for cognitive impairment seen in some chronic alcoholism subjects including molecular/metabolic alterations of phospholipid and ganglioside metabolisms.

  • Publication number: 20100010336
    Abstract: A method and system for medical imaging of neuropsychiatric disorders including attention deficit hyperactivity disorder (ADHD), autism, and schizophrenia. Noninvasive, in vivo methods identify novel brain molecular biomarkers of normal neurodevelopment in order to determine molecular underpinnings of abnormal neurodevelopment. The described brain molecular biomarkers will aid in the presymptomatic diagnosis of neuropsychiatric disorders which begin in childhood and adolescence, such as ADHD, autism, and schizophrenia.

  • Patent number: 7632662
    Abstract: Carnitines are nutraceuticals with indications in treating a variety of mental health disorders. A metabolomics-guided bioprocess method is presented to produce longer chain fatty acid esters of carnitines such as polyunsaturated fatty acid esters including eicosapentaenoyl-L-carnitine and/or docosahexaenyl-L-carnitine in germinating plant seeds. The resulting products from the plant seeds are used as a natural nutritional source of powerful human antioxidants.

  • Patent number: 7407778
    Abstract: Acetyl-L-carnitine (ALCAR) and L-carntine (LCAR) are nutraceuticals with indications in treating a variety of mental health disorders. A metabolomics-guided bioprocess method is presented to enhance ALCAR and LCAR formation in germinating plant seeds. Metabolic fluxes are manipulated by germination in bioreactors to increase oxygen availability as well as provide an aseptic environment to alter carbohydrate consumption and feedback repress gluconeogenesis. Large shifts in sunflower seed fatty acid, phospholipid and high-energy metabolism change the germination environment and these metabolic changes lead to an approximate 1000-fold increase in natural LCAR and ALCAR production by the seeds. The resulting LCAR and ALCAR products from the seeds are used for treating mental health disorders including Alzheimer's disease, geriatric depression, non-geriatric depression and schizophrenia.
