METHODS OF TREATING BRAIN DISORDERS OR IDENTIFYING BIOMARKERS RELATED THERETO
The present disclosure relates in part to methods of treating cognitive disorders and/or identifying biomarkers.
1 . A method of treating a cognitive disorder or enhancing cognitive function and/or learning in a patient in need thereof, comprising:
generating a MRI signal that is a measurement of brain activity in a patient;
identifying the signal as a normal or abnormal brain state of the patient; and
administering to the patient an effective amount of GLYX-13 based on the signal identification.
2 . The method of claim 1 , wherein the generating an MRI signal comprises using functional magnetic resonance imaging.
3 . The method of claim 2 , wherein the functional magnetic resonance imaging comprises blood-oxygen-level dependent contrast imaging.
4 . The method of claim 1 , wherein the brain activity is neural activation.
5 . The method of claim 4 , wherein the neural activation is neural activation in learning and/or memory related regions of the brain.
6 . A method for identifying a biomarker related to neural activation, learning, or memory or identifying a patient population who is more susceptible to such disorders, comprising:
administering GLYX-13 to an animal;
imaging the animal using functional magnetic resonance to create measurable activity;
analyzing the activity; and
identifying the biomarker as result of the activity.
7 . The method of claim 6 , wherein using functional magnetic resonance to create measurable activity comprises using blood-oxygen-level dependent contrast imaging.
8 . The method of claim 7 , wherein the measurable activity comprises changes in blood flow and/or blood oxidation in one or more regions of the brain in the animal.
9 . The method of claim 6 or 7 , wherein the biomarker is a blood-oxygen-level dependent contrast signal in one or more regions of the brain in the animal.
10 . The method of claim 6 , wherein the method further comprises associating a patient or subpopulation of patients with the biomarker.
11 . The method of claim 6 , wherein the method further comprises one or both of the following: (a) determining whether GLYX-13 would be therapeutically effective for treating a cognitive or mental disorder; and (b) determining susceptibility/receptivity in patient or a subpopulation of patients suffering from a cognitive or mental disorder.
12 . The method of claim 11 , wherein the mental disorder is depression.
13 . The method of claim 11 , wherein the depression is refractory.
14 . A method of treating a disorder selected from the group consisting of epilepsy, AIDS dementia, multiple system atrophy, progressive supra-nuclear palsy, Friedrich's ataxia, autism, fragile X syndrome, tuberous sclerosis, attention deficit disorder, olivio-ponto-cerebellar atrophy, cerebral palsy, drug-induced optic neuritis, peripheral neuropathy, myelopathy, ischemic retinopathy, glaucoma, cardiac arrest, behavior disorders, impulse control disorders, attention deficit disorder, attention deficit hyperactivity disorder, schizophrenia, anxiety, amelioration of opiate, nicotine and/or ethanol addiction, spinal cord injury, diabetic retinopathy, traumatic brain injury, post-traumatic stress syndrome, Huntington's chorea, Alzheimer's disease, memory loss that accompanies early stage Alzheimer's disease, depression conditions, Major Depressive Disorder, Dysthymic Disorder, Psychotic depression, Postpartum depression, Seasonal affective disorder (SAD), mood disorder, depressions caused by chronic medical conditions such as cancer or chronic pain, chemotherapy, chronic stress, Bipolar disorder, and manic depressive disorder, in a patient in need thereof, comprising:
generating a MRI signal that is a measurement of brain activity in a patient;
identifying the signal as a normal or abnormal brain state of the patient; and
administering to the patient an effective amount of GLYX-13 based on the signal identification.
15 . The method of claim 14 , wherein the generating an MRI signal comprises using functional magnetic resonance imaging.
16 . The method of claim 15 , wherein the functional magnetic resonance imaging comprises blood-oxygen-level dependent contrast imaging.
17 . A method for identifying a biomarker related to a disorder selected from the group consisting of epilepsy, AIDS dementia, multiple system atrophy, progressive supra-nuclear palsy, Friedrich's ataxia, autism, fragile X syndrome, tuberous sclerosis, attention deficit disorder, olivio-ponto-cerebellar atrophy, cerebral palsy, drug-induced optic neuritis, peripheral neuropathy, myelopathy, ischemic retinopathy, glaucoma, cardiac arrest, behavior disorders, impulse control disorders, attention deficit disorder, attention deficit hyperactivity disorder, schizophrenia, anxiety, amelioration of opiate, nicotine and/or ethanol addiction, spinal cord injury, diabetic retinopathy, traumatic brain injury, post-traumatic stress syndrome, Huntington's chorea, Alzheimer's disease, memory loss that accompanies early stage Alzheimer's disease, depression conditions, Major Depressive Disorder, Dysthymic Disorder, Psychotic depression, Postpartum depression, Seasonal affective disorder (SAD), mood disorder, depressions caused by chronic medical conditions such as cancer or chronic pain, chemotherapy, chronic stress, Bipolar disorder, and manic depressive disorder, or identifying a patient population who is more susceptible to such disorders, comprising:
administering GLYX-13 to an animal;
imaging the animal using functional magnetic resonance to create measurable activity;
analyzing the activity, and
identifying the biomarker as result of the activity.
18 . The method of claim 17 , wherein using functional magnetic resonance to create measurable activity comprises using blood-oxygen-level dependent contrast imaging.
19 . The method of claim 18 , wherein the measurable activity comprises changes in blood flow and/or blood oxidation in one or more regions of the brain in the animal.
20 . The method of claim 18 or 19 , wherein the biomarker is a blood-oxygen-level dependent contrast signal in one or more regions of the brain in the animal.
21 . The method of claim 17 , wherein the method further comprises associating a patient or subpopulation of patients with the biomarker.
22 . The method of claim 17 , wherein the method further comprises one or both of the following: (a) determining whether GLYX-13 would be therapeutically effective for treating the disorder; and (b) determining susceptibility/receptivity in a patient or a subpopulation of patients suffering from the disorder.
23 . A method for tracking treatment progress and/or treatment endpoints in a patient suffering from a cognitive or mental disorder comprising
generating a MRI signal that is a measurement of brain activity in a patient;
identifying the signal as a normal or abnormal brain state of the patient;
and administering to the patient an effective amount of GLYX-13 based on the signal identification.
