We reviewed our deep brain stimulation patient database to describe hardware complications which resulted from implantable pulse generator mobility, a phenomenon referred to as Twiddler's syndrome. A prospectively collected database of adverse events for all patients operated on at the University of Florida was queried searching for hardware malfunctions.(More)
DBS depends on precise placement of the stimulating electrode into an appropriate target region. Image-based (direct) targeting has been limited by the ability of current technology to visualize DBS targets. We have recently developed and employed a Fast Gray Matter Acquisition T1 Inversion Recovery (FGATIR) 3T MRI sequence to more reliably visualize these(More)
BACKGROUND Deep brain stimulation (DBS) is a treatment for patients with Parkinson's disease (PD) who are not adequately controlled with medications. An artist reported changes in her artistic creativity and art appreciation when treated with left DBS. We sought to study her artistic productions and her appreciation of art while both "on" and "off" left(More)
Invasive treatment for Gilles de la Tourette syndrome has shown interesting results in a number of published reports; it seems to be evolving into a promising therapeutic procedure for those patients demonstrating disabling clinical pictures who are refractory to conservative treatments. There are important issues concerning the stimulated brain target,(More)
OBJECTIVE To determine how intraoperative microelectrode recordings (MER) and intraoperative lead placement acutely influence tremor, rigidity, and bradykinesia. Secondarily, to evaluate whether the longevity of the MER and lead placement effects were influenced by target location (subthalamic nucleus (STN) or globus pallidus interna (GPi)). BACKGROUND(More)
BACKGROUND Deep brain stimulation (DBS) has emerged as an important treatment for medication refractory movement and neuropsychiatric disorders. General neurologists and even general practitioners may be called upon to screen potential candidates for DBS. The patient selection process plays an important role in this procedure.

UNLABELLED LAY SUMMARY: This case report illustrates lack of clinical efficacy of deep brain stimulation (DBS) for control of tics in a case of mild Tourette syndrome (TS) with severe comorbid obsessive-compulsive disorder (OCD). The brain target for stimulation was the anterior limb internal capsule (ALIC). OBJECTIVE To investigate the effect of anterior(More)
We recently treated six patients for OCD utilizing deep brain stimulation (DBS) of the anterior limb of the internal capsule and the nucleus accumbens region (ALIC-NA). We individually tested leads via a scripted intraoperative protocol designed to determine DBS-induced side effects and mood changes. We previously published qualitative data regarding our(More)
Pseudobulbar affect (PBA) is an affective disinhibition syndrome characterized by sudden, involuntary outbursts of inappropriate crying or laughing. We have previously reported the prevalence of PBA in movement disorders using an interviewer-administered questionnaire that had not been validated. In the current study, a validated self-administered screening(More)
Dystonic tremor, which may present with many different clinical presentations (rhythmic oscillations, abnormal posture, pain, and/or a null point) has proven to be a challenge for the clinician to effectively treat. Although recent studies have demonstrated excellent outcomes in select cases following deep brain stimulation (DBS) of the internal globus(More)
