Bipolar disorder (BD) is a complex and disabling disorder that is among the most challenging diagnoses in psychiatry. Although episodes of mania and hypomania define the different types of the disorder, the clinical picture is one dominated by depressed mood and agitation. Detection and diagnosis of BD remains a challenge, as most individuals with BD spend many years misdiagnosed as major depression disorder (MDD), often leading to under-treatment or inappropriate treatment. Several studies have attempted to elucidate features of a major depressive episode that indicate an underlying diagnosis of MDD versus bipolar depression.~During the last fifteen years, there have been significant advances in our understanding of the pathophysiology and relevant neuroanatomy and neurocircuitry underlying mood disorders. Much of that progress has been made as a result of technological advances in neuroimaging, both structural and functional.~Deep Brain Stimulation is a neurosurgical tool has been used for over twenty-five years to treat various neurologic and psychiatric conditions. DBS is believed to work by using small amounts of electricity to disrupt the activity of brain structures that produce troublesome symptoms. In the case of Parkinson's disease, DBS is successful in treating the tremor and general slowing that are major parts of that condition. DBS has also been used in psychiatric patients, both as part of treatment, in cases of Obsessive-Compulsive Disorder (OCD), and research, in cases of Depression. The successful use of deep brain stimulation (DBS) in movement disorders, and its promising results in major depressive disorder (MDD), has led researchers to consider its use in highly selected refractory cases of BD. Evidence form the imaging and circuitry literature suggests that similar underlying dysfunctional anatomic structures subserve both MDD and BD, indicating that modulation of key structures, can lead to an amelioration of symptoms and mood stabilization.~Our primary objective is to establish the safety of deep brain stimulation in a patient population with treatment refractory bipolar disorder.
Bipolar Disorder (BD) is among the most comon and challenging conditions in psychiatry. Although episodes of mania and hypomania define the different types of the disorder, the clinical picture is one dominated by depressed mood and agitation. The mainstay of BD treatment has thus far been pharmacologic, but many patients remain severely disabled by their condition, despite the best available medical treatment. The successful use of deep brain stimulation (DBS) in movement disorders, and its promising results in major depressive disorder (MDD), has led researchers to consider its use in highly selected refractory cases of BD. Evidence form the imaging and circuitry literature suggests that similar underlying dyfunctional anatomic structures subserve both MDD and BD, indicating that modulation of key structures, can lead to an amelioration of symptoms and mood stabilization. Here, we propose a phase I clinical trial to evaluate the safety of DBS in BD.
