Randomized Controlled TrialA randomised controlled trial of a home based exercise programme to reduce the risk of falling among people with Parkinson's disease.
To evaluate the effectiveness of a personalised home programme of exercises and strategies for repeat fallers with Parkinson's disease (PD). ⋯ There was a trend towards a reduction in fall events and injurious falls with a positive effect of exercises on near falls and quality of life.

Imaging occupies an important role in the investigation of dementia and neurodegenerative disease. The role of imaging in prion disease used to be one of exclusion of other conditions. ⋯ As experience of imaging in human prion disease increases, patterns of change related to strain and genotype may improve the diagnostic potential of imaging in the future, may reduce the need for more invasive testing and prove useful in future therapeutic trials. This paper reviews the current knowledge of imaging appearances in human prion disease.

Randomized Controlled TrialAchieved serum magnesium concentrations and occurrence of delayed cerebral ischaemia and poor outcome in aneurysmal subarachnoid haemorrhage.
Magnesium therapy probably reduces the frequency of delayed cerebral ischaemia (DCI) in subarachnoid haemorrhage (SAH) but uncertainty remains about the optimal serum magnesium concentration. We assessed the relationship between serum magnesium concentrations achieved with magnesium sulphate therapy 64 mmol/day and the occurrence of DCI and poor outcome in patients with SAH. ⋯ Magnesium sulphate 64 mmol/day results in a stable risk reduction of DCI over a broad range of achieved serum magnesium concentrations, and strict titration of the dosage therefore does not seem necessary. However, concentrations < or = 1.28 mmol/l could decrease the effect on DCI while concentrations > or = 1.62 might have a negative effect on clinical outcome.

Epidemiology of benign paroxysmal positional vertigo: a population based study.
To examine the prevalence and incidence, clinical presentation, societal impact and comorbid conditions of benign paroxysmal positional vertigo (BPPV) in the general population. ⋯ BPPV is a common vestibular disorder leading to significant morbidity, psychosocial impact and medical costs.

Clinical TrialClinical significance of preoperative fibre-tracking to preserve the affected pyramidal tracts during resection of brain tumours in patients with preoperative motor weakness.
To clarify the clinical usefulness of preoperative fibre-tracking in affected pyramidal tracts for intraoperative monitoring during the removal of brain tumours from patients with motor weakness. ⋯ Preoperative fibre-tracking could predict the clinical usefulness of intraoperative electrical stimulation of the motor cortex and subcortical fibres (ie, pyramidal tracts) to preserve affected motor function during removal of brain tumours. In patients for whom fibre-tracking failed preoperatively, awake surgery is more appropriate to evaluate and preserve moderately impaired muscle strength.
