Deep brain stimulation parameters associated with neuropsychological changes in subthalamic nucleus stimulation for refractory Parkinson's disease.

Background/aims: Parkinson's disease (PD) is an idiopathic progressive neurological disorder. Improvement in motor function of PD patients has been established with subthalamic nucleus (STN) deep brain stimulation (DBS). While variations in DBS settings (i.

The importance of shunt valve position in flow characteristics of the Medtronic PS Medical Delta valve.

This study was conducted to document the extent to which flow depends on valve position in relation to head-pressure reference. Medtronic PS Medical Delta valves (contour model, performance levels 0.5, 1.

A 15-year-old female with progressive myelopathy.

March 2005. A 15-year-old female presented with urinary retention, inability to walk and low back pain. MRI disclosed an elongated epidural mass in the thoracic spine with cord compression and invasion into the surrounding bone and soft tissue.

Visual field defects in deformational posterior plagiocephaly.

Purpose: We sought to determine whether visual field abnormalities occur in infants with deformational posterior plagiocephaly and to assess whether there is a relationship between the severity and laterality of visual field abnormalities with the severity and laterality of skull deformity.

Methods: A retrospective chart review was performed on 40 consecutive infants with deformational posterior plagiocephaly. Each was tested with standardized binocular arc perimetry in the horizontal plane.

Functional reorganization of motor cortex due to brain tumor: a case report.

We report the case of a 39-year-old man with a brain tumor and 12 years of intractable partial epilepsy with secondary generalization. After extensive noninvasive and invasive evaluation the seizure focus was localized to the right fronto-parietal region. Functional cortical mapping (FCM) was performed after craniotomy and implantation of a subdural grid with 40 electrodes covering the epileptogenic focus and the adjacent cortex.
