Brain Stimulation for Treatment Resistant Depression

guida sulle opzioni binarie Clinicians believe deep brain stimulation (DBS)—originally developed to treat chronic pain, tremor, and epilepsy—may be suitable for treatment-resistant depression, as well. Cusin and colleagues define DBS as a reversible, neurosurgical procedure, in which electrodes are implanted at specific locations within the brain, and send electrical impulses varying in intensity and frequency.[1] A safe procedure, DBS is approved by the Food and Drug Administration (FDA) for the treatment of tremor, Parkinson’s disease, dystonia, and, in 2009, obsessive-compulsive disorder (OCD).1 Cusin and colleagues describe the short-term side effects of DBS as headache, incontinence, postoperative confusion, fatigue, memory difficulties, weight gain, and in three to four percent of cases, seizures.1

opcje binarne wskaźniki Research has shown that DBS can induce mood changes when certain locations are targeted, a discovery that ultimately led to continued examination of DBS and psychiatric disorders.1 Anterior capsulotomy, a procedure targeting the anterior limb of the internal capsule,1 was first performed as a treatment of severe OCD in France in 1949 by Tailarach and colleagues.[2] Cusin and colleagues state that anterior capsulotomy may be performed in two ways: thermocapsulotomy by neurosurgery or minimally-invasive gammacapsulotomy.1 In Sweden in 1961, Leksell and colleagues conducted a study of 116 patients who underwent thermocapsulotomy and reported a beneficial response in 50 percent of patients with OCD and 48 percent of patients with major depressive disorder.[3]

trading opzioni binarie cos/\\\\\\\\\'è Cusin and colleagues state that adhering to strict patient-selecting criteria is critical to the treatment’s success, and outline several factors that should be considered. First, the patient must meet the DSM-IV criteria for MDD, which also must be the patient’s primary disorder. Severity of the MDD must be chronic and debilitating, typically exceeding a duration of five years, and causing the patient to function on a low level and have a very poor quality of life.1 Second, the patient must have previously undergone multiple forms of treatment, including psychotherapy, pharmacotherapy, combination therapy, and electroconvulsive therapy, all of which have not shown significant improvement of symptoms.1 Patients with co-occurring psychiatric disorders, such as bipolar disorder, psychosis, substance abuse, and personality disorders do not qualify for DBS treatment. Also, patients with underlying medical disorders, such as brain lesions, central nervous system injuries, and seizure disorders, do not qualify either.1 Finally, and importantly, patients must have access to acceptable postoperative care, including a primary care doctor, a psychiatrist, and a psychotherapist.1

gute indikatoren für binäre optionen The procedure itself is described as “complex.”1 First, a head frame is used to obtain images of the patient’s brain, which allows for planning of electrode placement. The procedure uses a 3391 brain lead that is 1.27 mm in diameter and has four electrode contacts that are 3 mm long.1 The leads are implanted bilaterally in the ventral capsule and the ventral striatum, and during the process, the patient remains awake for the purpose of verbal feedback.1 Once the leads are in place, a test simulation is conducted in order to identify the improvement in mood. Next, postoperative imaging is taken to ensure correct placement.1 Finally, the patient is placed under general anesthesia and two neurostimulators are implanted under the clavicle in the chest area, and are connected to the electrodes with wires planted subcutaneously.1

Follow-up during the first six months is crucial to achieving effective stimulation parameters, and other therapies should be coordinated during this time for close monitoring.1 Stimulation is delivered consistently until battery depletion, which is usually once per year; however, replacing batteries has not shown to cause a lapse in treatment.1
