Systems and methods of treating a neurological disorder in a patient

Abstract

In embodiments of the present disclosure, methods of treating a neurological disorder comprise providing reconditioning electrical stimulation. The methods may comprise applying electrical stimulation that provides positive reinforcement by activation within the reward network of the brain of the patient when an appropriate external stimulus is provided to the patient. The external stimulus is selected in accordance with the specific neurological disorder being treated in the patient. The methods may comprise applying electrical stimulation that provides negative reinforcement by stimulation of aversion-related locations of the brain of the patient when a different external stimulus is provided to the patient.

1 . A method of treating a neurological disorder in a patient, comprising:
 providing one or more external stimuli to the patient relevant to the patient's neurological disorder; and   concurrently with providing the one or more external stimuli, electrically stimulating one or more locations in a brain of the patient to elicit a reward-response to the one or more external stimuli, to elicit a disreward response, or to elicit an aversion-response to the one or more external stimuli.   
     
     
         2 . The method of  claim 1  wherein the electrically stimulating comprising:
 applying electrical pulses according to a burst pattern of multiple bursts separated by quiescent intervals with each burst of the burst pattern comprising multiple electrical pulses or clustered firing. 
 
     
     
         3 . The method of  claim 1  further comprising:
 providing a first external stimulus for presentation concurrently with electrical stimulation of a reward-related location within the brain of the patient. 
 
     
     
         4 . The method of  claim 1  wherein the reward-related location is selected from the list consisting of: the nucleus accumbens (NAc), the laterodorsal tegmentum, ventral tegmental area (VTA), substantia nigra pars compacta, hypothalamus, the ventral pallidum, the subthalamic nucleus (STN), medial dorsal nucleus of the thalamus, and the posterior cingulate cortex (PCC). 
     
     
         5 . The method of  claim 3  further comprising:
 providing a second external stimulus for presentation concurrently with electrical stimulation of a disrewarding/antirewarding or aversion-related location within the brain of the patient. 
 
     
     
         6 . The method of  claim 5  wherein the reward-related location is selected from the list consisting of: the habenula, the rostromedial tegmental nucleus, ventral tegmental area (VTA), the amygdala, the dorsal anterior cingulate cortex (dACC), the dorsolateral prefrontal cortex (DLPFC), and the insula. 
     
     
         7 . The method of  claim 1  wherein the neurological disorder is an addiction or substance use disorder. 
     
     
         8 . The method of  claim 1  wherein the neurological disorder is an eating disorder. 
     
     
         9 . The method of  claim 1  wherein the neurological disorder is an auditory disorder. 
     
     
         10 . The method of  claim 9  wherein the auditory disorder is tinnitus. 
     
     
         11 . The method of  claim 1  wherein the neurological disorder is chronic pain. 
     
     
         12 . The method of  claim 1  wherein the neurological disorder is selected from the list consisting of depression, bipolar disorder, post-traumatic stress disorder (PTSD), panic disorder, phobia, schizophrenia, psychopathy, and antisocial personality disorder. 
     
     
         13 . The method of  claim 1  wherein the neurological disorder is a reward deficiency syndrome. 
     
     
         14 . The method of  claim 13  wherein the neurological disorder is an addictive disorder. 
     
     
         15 . The method of  claim 14  wherein the addictive disorder is selected from the list consisting of alcohol abuse, substance abuse, smoking, and obesity. 
     
     
         16 . The method of  claim 13  wherein the neurological disorder is an impulsive disorder. 
     
     
         17 . The method of  claim 16  wherein the impulsive disorder is selected from the list consisting of attention deficit hyperactivity disorder (ADHD), Tourette's syndrome, and autism. 
     
     
         18 . The method of  claim 13  wherein the neurological disorder is a compulsive disorder. 
     
     
         19 . The method of  claim 18  wherein the compulsive disorder is selected from the list consisting of obsessive compulsive disorder (OCD), gambling, and aberrant sexual behavior. 
     
     
         20 . The method of  claim 13  wherein the neurological disorder is a personality disorder.
