Abstract

Abstract A patient is diagnosed to determine whether the patient has a limbic system dysrhythmia and capable of being treated by administration of an anticonvulsant medication by determining whether the patient exhibits symptoms in at least four groups out of twelve defined groups of symptoms. In addition, an electroencephalogram is studied for any focal abnormalities in the temporal parietal areas and, if there are none, the patient is administered a local anaesthetic, procaine, and the electroencephalogram is evaluated for omega band activity (30-50 Hz). A patient exhibiting either focal abnormalities in the temporal-parietal areas on the standard electroencephalogram or, after procaine, exhibiting omega band activity of at least about three times the baseline voltage above normal and exhibiting symptoms in at least four groups of the twelve groups of defined symptoms is diagnosed as having Limbic System Dysrhythmia and being capable of treatment by administering an anticonvulsant medication.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 219 words
A method for diagnosing a patient to determine whether said patient has Limbic System Dysrhythmia and is susceptible of being treated by being administered an anticonvulsant medication which method comprises diagnosing said patient to determine whether said patient exhibits at least four of the twelve groups of symptoms selected from the group consisting of mood change, panic attacks, rage reaction, headaches, addictive states, learning disability, paranoid episodes or thinking, peripheral neuropathic signs, seizure-like phenomena, self-destructive behavior, autoimmune-endocrine disorders and antidepressant stimulant response; performing on said patient at least one test selected from the group consisting of: (a) An electroencephalographic test employing anteriortemporal leads, and analyzing the results of said electroencephalographic test looking for the condition of focal abnormalities in the temporal-parietal areas; and, (b) Administering a local anaesthetic intravenously to said patient, then performing an electroencephalographic test employing anterior-temporal leads, and analyzing the results of said electroencephalographic test looking for the condition of omega activity (30-50 Hz.) of at least approximately three times the baseline voltage in the anterior-temporal leads and, if the patient exhibits symptoms in at least four groups of said twelve groups of symptoms and exhibits at least one of the above conditions in (a) or (b) said patient is diagnosed as having Limbic System Dysrhythmia and is susceptible of being treated with an anticonvulsant medication.
Claim 2
Independent Claim 219 words
A method for diagnosing a patient to determine whether said patient has Limbic System Dysrhythmia and is susceptible of being treated by being administered an anticonvulsant medication which method comprises diagnosing said patient to determine whether said patient exhibits at least four of the twelve groups of symptoms selected from the group consisting of mood change, panic attacks, rage reaction, headaches, addictive states, learning disability, paranoid episodes or thinking, peripheral neuropathic signs, seizure-like phenomena, self-destructive behavior, autoimmune-endocrine disorders and antidepressant stimulant response; performing on said patient at least one test selected from the group consisting of: (a) An electroencephalographic test employing anteriortemporal leads, and analyzing the results of said electroencephalographic test looking for the condition of focal abnormalities in the temporal-parietal areas; and, (b) Administering a local anaesthetic intravenously to said patient, then performing an electroencephalographic test employing anterior-temporal leads, and analyzing the results of said electroencephalographic test looking for the condition of omega activity (30-50 Hz.) of at least approximately three times the baseline voltage in the anterior-temporal leads and, if the patient exhibits symptoms in at least four groups of said twelve groups of symptoms and exhibits at least one of the above conditions in (a) or (b) said patient is diagnosed as having Limbic System Dysrhythmia and is susceptible of being treated with an anticonvulsant medication.
Claim 3
Dependent Claim 11 words
The method of claim 1 wherein said local anaesthetic is procaine.
Claim 4
Dependent Claim 42 words
The method of claim 1 which further comprises intravenously administering to said patient a local anaesthetic at a dosage of about 1.38 mg/kg of body weight in a volume of about 3-6 cc prior to performing said electroencephalographic test on said patient.
Claim 5
Dependent Claim 24 words
The method of claim 1 wherein said omega activity of at least approximately three times the baseline voltage is at least about 45 microvolts.
Claim 6
Independent Claim 245 words
A method for treating a patient suffering from mental disorder which comprises diagnosing said patient to determine whether said patient has Limbic System Dysrhythmia and is susceptible of being treated by being administered an anticonvulsant medication by diagnosing said patient to determine whether said patient exhibits symptoms in at least four groups of the twelve groups of symptoms consisting of mood change, panic attacks, rage reaction, headaches, addictive states, learning disability with or without symptoms of ADHD, paranoid episodes or thinking, peripheral neuropathic signs, seizure-like phenomena, self-destructive behavior, autoimmune endocrine disorders and antidepressant stimulant response; performing on said patient at least one test selected from the group consisting of: (a) An electroencephalographic test employing anteriortemporal leads, and analyzing the results of said electroencephalographic test looking for the condition of focal abnormalities in the temporal-parietal areas; and, (b) Administering a local anaesthetic intravenously to said patient, then performing an electroencephalographic test employing anterior-temporal leads, and analyzing the results of said electroencephalographic test looking for the condition of omega activity (30-50 Hz.) of at least about three times baseline voltage in the anterior-temporal leads and, if the patient exhibits symptoms in at least four groups of said twelve groups in at least four of said 12 groups and exhibits at least one of the above conditions in (a) or (b) said patient is diagnosed as having Limbic System Dysrhythmia and is susceptible of being treated with an anticonvulsant medication; and administering an anticonvulsant medication to said patient.
Claim 7
Independent Claim 245 words
A method for treating a patient suffering from mental disorder which comprises diagnosing said patient to determine whether said patient has Limbic System Dysrhythmia and is susceptible of being treated by being administered an anticonvulsant medication by diagnosing said patient to determine whether said patient exhibits symptoms in at least four groups of the twelve groups of symptoms consisting of mood change, panic attacks, rage reaction, headaches, addictive states, learning disability with or without symptoms of ADHD, paranoid episodes or thinking, peripheral neuropathic signs, seizure-like phenomena, self-destructive behavior, autoimmune endocrine disorders and antidepressant stimulant response; performing on said patient at least one test selected from the group consisting of: (a) An electroencephalographic test employing anteriortemporal leads, and analyzing the results of said electroencephalographic test looking for the condition of focal abnormalities in the temporal-parietal areas; and, (b) Administering a local anaesthetic intravenously to said patient, then performing an electroencephalographic test employing anterior-temporal leads, and analyzing the results of said electroencephalographic test looking for the condition of omega activity (30-50 Hz.) of at least about three times baseline voltage in the anterior-temporal leads and, if the patient exhibits symptoms in at least four groups of said twelve groups in at least four of said 12 groups and exhibits at least one of the above conditions in (a) or (b) said patient is diagnosed as having Limbic System Dysrhythmia and is susceptible of being treated with an anticonvulsant medication; and administering an anticonvulsant medication to said patient.
