METHOD OF TREATING COGNITIVE DISORDERS USING NEUROMODULATION
The present invention involves a method and a system for using electrical stimulation and/or chemical stimulation to treat a cognitive impairment and/or disorder. More particularly, the method comprises surgically implanting an electrode and/or catheter that is in communication with a predetermined site which is coupled to a pulse generating source and/or infusion pump that release either an electrical signal and/or a pharmaceutical resulting in stimulation of the predetermined site thereby treating the cognitive disorder and/or enhancing the cognitive ability.
1 . A method of treating a patient diagnosed with Alzheimer's Disease, said method comprising the steps of:
surgically implanting an electrode in a subcallosal area of a brain of the patient diagnosed with Alzheimer's disease;
coupling the electrode to a pulse generating source; and
generating an electrical signal with the pulse generating source wherein said signal electrically stimulates the area thereby treating the Alzheimer's disease.
2 . The method of claim 1 , wherein the pharmaceutical is selected from the group consisting of an inhibitory neurotransmitter agonist, an excitatory neurotransmitter antagonist, an agent that increases the level of an inhibitory neurotransmitter, an agent that decreases the level of an excitatory neurotransmitter, and a local anesthetic agent.
3 . The method of claim 1 , further comprising the steps of:
surgically implanting a catheter having a proximal end coupled to a pump and a discharge portion for infusing a dosage of a pharmaceutical, wherein after implantation the discharge portion of the catheter is in communication with the area; and
operating the pump to discharge the pharmaceutical through the discharge portion of the catheter into the area thereby treating the Alzheimer's disease.
4 . A method of treating a patient diagnosed with Alzheimer's Disease, said method comprising the steps of:
surgically implanting an electrode in a subgenual cingulate area of the patient diagnosed with Alzheimer's disease;
coupling the electrode to a pulse generating source; and
generating an electrical signal with the pulse generating source wherein said signal electrically stimulates the area thereby treating the Alzheimer's disease.
5 . The method of claim 4 , further comprising the steps of:
surgically implanting a catheter having a proximal end coupled to a pump and a discharge portion for infusing a dosage of a pharmaceutical, wherein after implantation the discharge portion of the catheter is in communication with the area; and
operating the pump to discharge the pharmaceutical through the discharge portion of the catheter into the area thereby treating the Alzheimer's disease.
