Gender-specific differences in stroke knowledge, stroke risk perception and the effects of an educational multimedia campaign.
This study aimed at identifying gender-specific differences in stroke knowledge, stroke risk perception and the educational effects of a multimodal educational intervention. We performed computer-assisted telephone surveys among an average sample of 500 members of the general public (44.0% male, 56.0% female), before and immediately after an intense 3-month educational stroke campaign in a western German area of 400,000 inhabitants. The intervention was comprised of poster advertisements and various print media. ⋯ Our data indicate that educational programs do have gender-specific effects. Women show a better stroke knowledge and in some aspects a better chance to gain information from classical broad educational interventions. Future campaigns should be tailored economically, and should focus different media and educational messages on the two sexes accordingly.

Comparative Study Clinical TrialAcquired pendular nystagmus in multiple sclerosis: an examiner-blind cross-over treatment study of memantine and gabapentin.
A prospective examiner-blind, cross-over study was conducted to compare the efficacy of memantine (40 or 60 mg/day) and gabapentin (1,200 mg/day) as therapy for acquired fixational pendular nystagmus (APN) in 11 patients with multiple sclerosis. APN was documented in 20 eyes by electrooculography (EOG). The primary objective of the study was an at least 50% reduction in amplitude and/or frequency of APN compared with baseline values in EOG. ⋯ In two other eyes APN completely subsided with gabapentin 1,200 mg only, but not with memantine. Near visual acuity, a secondary outcome parameter, improved by at least 0.1 in 11 of 17 eyes treated with memantine and in 8 out of 16 eyes treated with gabapentin. In summary, memantine and gabapentin are safe and effective treatment options for APN.

Massive intraventricular haemorrhage from aneurysmal rupture: patient proportions and eligibility for intraventricular fibrinolysis.
Massive intraventricular haemorrhage (IVH) complicating aneurysmal subarachnoid haemorrhage (SAH) is associated with a poor prognosis. Small observational studies suggest favourable results from fibrinolysis of the intraventricular blood. We performed an observational study on IVH in a large series of patients with SAH to assess the proportion of patients that may benefit from fibrinolytic treatment. ⋯ Massive IVH occurs in 10% of patients with aneurysmal SAH. Half of these patients may benefit from intraventricular fibrinolysis. Without fibrinolysis outcome is almost invariably poor in these patients.

The thalamic ultrastructural abnormalities in paroxysmal kinesigenic choreoathetosis: a diffusion tensor imaging study.
Paroxysmal kinesigenic choreoathetosis (PKC) is a rare neurologic disorder. There are not apparent morphological changes in patients with idiopathic PKC. The purpose of this study is to determine whether ultrastructural changes are in the brain of patients with idiopathic PKC using diffusion tensor imaging. ⋯ FA and MD values were not significantly correlated with age of onset, gender, frequency of attack and duration of the disease. The results showed that in patients with idiopathic PKC, diffusion tensor imaging discloses distinct ultrastructural abnormalities in the thalamus. DTI is a sensitive neuroradiologic technique for detecting cerebral alterations in patients even without visible lesions on conventional MRI.

SPECT and PET analysis of subthalamic stimulation in Parkinson's disease: analysis using a manual segmentation.
The subthalamic nucleus (STN) has become an effective target of deep-brain stimulation (DBS) in severely disabled patients with advanced Parkinson's disease (PD). Clinical studies have reported DBS-induced adverse effects on cognitive functions, mood, emotion and behavior. STN DBS seems to interfere with the limbic functions of the basal ganglia, but the limbic effects of STN DBS are controversial. ⋯ A non-significant decrease in rCMb in the left anterior cingulate gyrus appeared following STN DBS (p = 0.075). Our prospective SPECT and PET study revealed significantly decreased glucose metabolism of the two superior frontal gyri without any attendant perfusion changes following STN DBS. These results suggest that STN DBS may change medial prefrontal function and therefore the integration of limbic information, either by disrupting emotional processes within the STN, or by hampering the normal function of a limbic circuit.
