Levodopa/carbidopa intestinal gel (LCIG) infusion is nowadays becoming an established therapeutic option for advanced Parkinson's disease (PD) patients with fluctuating symptoms unresponsive to conventional oral treatment. As the implementation of LCIG therapy is increasing, there is a need for safety and efficacy data from current clinical practice. ⋯ LCIG infusion is effective for the long-term treatment of advanced PD patients and exerts a positive and clinically significant effect on motor complications with a relatively low dropout rate.

The thalamus seems to be profoundly involved in the cyclical recurrence of migraine clinical and neurophysiological features. Here possible structural changes in the thalamus of migraineurs were searched for by means of diffusion tensor (DT) magnetic resonance imaging (MRI). This MRI technique provides quantitative data on water molecule motion as a marker of tissue microstructure. ⋯ These higher thalamic FA values noted during the interictal period which normalized during an attack are probably related to plastic peri-ictal modifications in regional branching and crossing of fibres. Whether these changes could be considered as the anatomical counterpart of the cyclical functional fluctuations previously observed in the neurophysiology of migraine remains to be determined.

Lumbar puncture (LP) is a key diagnostic procedure in medicine. Post lumbar puncture headache (PLPHA) is a well recognized complication of LP. Evidence suggests that using atraumatic needles for diagnostic LP (ATNLP) reduces risk of PLPHA. However, clinicians in Europe and the USA routinely use traumatic needles for diagnostic LP (TNLP). The occurrence of PLPHA following ATNLP and TNLP was compared in a clinical setting. Further, a survey was performed exploring use of ATNLP amongst UK neurologists. ⋯ ATNLP significantly reduces the risk of PLPHA. Training is required 3 to facilitate a change from TNLP to ATNLP amongst clinicians.

External counterpulsation (ECP) is a novel method to increase cerebral blood flow, which may benefit acute ischaemic stroke patients. Our aim was to identify whether the hemodynamic effect of ECP is associated with cerebral vasoreactivity to breath-holding. ⋯ The dynamic augmentation effects of ECP as measured by the CAI were different from the well established vasoreactivity to breath-holding. The CAI is suggested as a measure of how well the brain accommodates blood flow augmentation during ECP.
