Deep brain stimulation for obsessive-compulsive disorder: a systematic review of randomised controlled trials

Publication date: Available online 7 January 2020Source: Neuroscience &Biobehavioral ReviewsAuthor(s): Petya Vicheva, Matthew Butler, Paul ShotboltAbstractDeep brain stimulation (DBS) is considered a promising intervention for treatment-resistant obsessive-compulsive disorder (trOCD). We conducted a systematic search to investigate the efficacy and safety of DBS for OCD. Primary outcomes included the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), adverse events (AE), and quality of life. We assessed affective state, global functioning, cognition, and tolerability as secondary outcomes. Eight studies comprising 80 patients with trOCD were analysed both individually and collectively. We found a pooled mean reduction in Y-BOCS of 38.68%, indicating DBS could be considered an effective therapy for trOCD. Most AE were mild and transient, however there were five severe surgery-related AE: intracerebral haemorrhage in three patients and infection in two. Mood-related serious AE were one completed suicide, three suicide attempts in two patients, and suicidal thoughts and depression in four. Despite this, affective state improved following stimulation. Despite being limited by significant heterogeneity across studies, our review has shown DBS to be an effective treatment in otherwise trOCD. There is a need to standardise study methodology in future research.

Atrial fibrillation is the most common sustained cardiac arrhythmia in the general population. In western countries with aging populations, atrial fibrillation poses a significant health concern, as it is associated with a high risk of thromboembolism, stroke, congestive heart failure, and myocardial infarction. Thrombi are generated in the left atrial appendage, and subsequent embolism into the cerebral circulation is a major cause of ischemic stroke. Therefore, patients have a lifetime risk of stroke, and those at high risk, defined as a CHA2DS2-VASc2 (congestive heart failure, hypertension, age>75 years, diabetes mel...

Authors: Meregildo ED Abstract Neurocysticercosis (NCC) is a global health problem. In more developed countries, NCC is mainly a disease affecting immigrants. In developing countries, NCC is the most common parasitic disease of the nervous system and the main cause of acquired epilepsy. NCC is also an unrecognized cause of strokes and could account for 4%-12% of strokes. Here, I report a case of a 58-year-old woman who presented to the emergency department (ED) with severe headache, vomiting, and sudden loss of consciousness. Multiple NCC and Fisher grade 4 aneurysmal subarachnoid hemorrhage (SAH) were demonstrated...

Parkinson’s disease (PD) is characterized by the progressive loss of dopaminergic neurons in the substantia nigra. However, other non-dopaminergic neuronal systems such as the serotonergic system are also involved. Serotonergic dysfunction is associated with non-motor symptoms and complications, including anxiety, depression, dementia, and sleep disturbances. This pathology reduces patient quality of life. Interaction between the serotonergic and other neurotransmitters systems such as dopamine, noradrenaline, glutamate, and GABA controls the activity of striatal neurons and are particularly interesting for understan...

In 2019, the Congressional Black Caucus convened an emergency Taskforce to examine Black Youth Suicide and Mental Health. The Taskforce released its report in December 2019, highlighting several recommendations for increased research, intervention development, and community engagement. In collaboration with the Office of Behavioral Health Equity at SAMHSA, this 90-minute interactive roundtable webinar featured co-authors of the Taskforce report, including the leader of the Taskforce, answering our most pressing questions about Black youth suicide.
