Clinical Trial
Quantitative continuous EEG for detecting delayed cerebral ischemia in patients with poor-grade subarachnoid hemorrhage.
Delayed cerebral ischemia (DCI) due to vasospasm is often undetected by clinical exam in patients with poor-grade subarachnoid hemorrhage (SAH). The purpose of this study was to identify quantitative EEG (qEEG) parameters that are most sensitive and specific for the detection of DCI in stuporous or comatose SAH patients. ⋯ Following ADRs may allow earlier detection of DCI and initiation of interventions at a reversible stage, thus preventing infarction and neurological morbidity.

To study temporal and spatial development of EEG patterns in sporadic and iatrogenic Creutzfeldt-Jakob disease patients. ⋯ FIRDA occur at an early stage of CJD and are progressively replaced by the classical PSWC. The EEG patterns of CJD are sensitive to midazolam. The initial EEG changes in iatrogenic CJD are seen at the site of prion exposure.

To disclose a possible effect of duration of pulsed laser heat stimuli on Adelta nociceptor responses, skin temperature profiles, brain evoked potentials and pain perception. ⋯ The shorter stimulus duration shortens receptor activation times and yields a more synchronous afferent volley, thus providing a stronger spatial-temporal summation at central synapses that enhances intensity of first pain and brain potentials. This may prove useful in clinical applications.

Randomized Controlled Trial Clinical Trial
Improvement of motor performance and modulation of cortical excitability by repetitive transcranial magnetic stimulation of the motor cortex in Parkinson's disease.
To assess the effects of focal motor cortex stimulation on motor performance and cortical excitability in patients with Parkinson's disease (PD). ⋯ The present study gives some clues to appraise the role of the primary motor cortex in PD. Clinical improvement induced by rTMS was too short-lasting to consider therapeutic application, but these results support the perspective of the primary motor cortex as a possible target for neuromodulation in PD.

To describe a case with night terrors (NT) symptomatic of a thalamic lesion. ⋯ A thalamic dysfunction, disrupting at this level the arousal system, may play a role in provoking NT.
