Deep brain stimulation (DBS) is an established therapy for Parkinson's Disease and is being investigated as a treatment for chronic depression, obsessive compulsive disorder and for facilitating functional recovery of patients in minimally conscious states following brain injury. For all of these applications, quantitative assessments of the behavioral effects of DBS are crucial to determine wh...

Subthalamic deep brain stimulation (STN DBS) is an established treatment for the motor symptoms in patients with advanced Parkinson's disease (PD). In addition to improvements in motor symptoms, many studies have reported changes in various nonmotor symptoms (NMSs) after STN DBS in patients with PD. Psychiatric symptoms, including depression, apathy, anxiety, and impulsivity, can worsen or impr...

BACKGROUND In HIV-infected patients, therapeutic drug monitoring (TDM) of antiretroviral drugs is recommended in special populations and in specific situations to optimize therapy. Currently, TDM is performed via measurement of drug plasma concentrations; however, dried blood spots (DBS) may offer a patient friendly and cost-effective alternative. Therefore, this proof-of-concept study assessed...

The analysis of long-latency event-related potentials (ERPs) is of importance in the evaluation of certain cognitive functions and in following their subsequent changes. The aim of the present study was to investigate whether deep brain stimulation (DBS) itself can cause changes in the configuration of the ERPs. Using a standard oddball auditory paradigm, we elicited auditory cognitive ERPs in ...

The effectiveness of deep brain stimulation (DBS) in relieving the symptoms of movement disorders is dependent on the average frequency of stimulation. However, no one has yet examined whether the effectiveness of DBS in relieving tremor is dependent on the pulse-to-pulse (instantaneous) frequency of DBS. We examined the effects of paired-pulse thalamic DBS on tremor in subjects with essential ...

INTRODUCTION Many people at high risk for sexually transmitted infections (STIs), e.g., men who have sex with men (MSM), are not optimally reached by current sexual health care systems with testing. To facilitate testing by home-based sampling or sampling in outreach setting we evaluated dried blood spots (DBS), a method for self-collected blood sampling for serological screening of HIV, hepati...

Abstract Objective: Since the development of new deep brain stimulation (DBS) devices in recent years, there is an increased need for assessing safety combination with transcranial magnetic (TMS). Methods: We applied a combined ex vivo and computational approach to investigate TMS using Boston Scientific segmented electrode. TMS-induced current was measured between electrode lead extension, dif...

Deep brain stimulation (DBS) of the ventral capsule/ventral striatum (VC/VS) is a novel therapy for neuropsychiatric disorders. Hypomania is a known complication of VC/VS DBS, but who is at risk is less understood. Factors such as family history, combined with details of DBS programming, might quantify that risk. The authors performed an iterative modeling procedure on a VC/VS DBS patient regis...

Deep brain stimulation (DBS) has become an important treatment option for carefully screened medication resistant neurological and neuropsychiatric disorders. DBS therapy is not always applied deep to the brain; does not have to be applied exclusively to the brain; and the mechanism for DBS is not simply stimulation of structures. The applications and target locations for DBS devices are rapidl...
