Family A was characterized by late onset MELAS in two members, CPEO in one, and mild CNS involvement in another. 20-61% of mtDNA of affected and unaffected individuals was mutated in muscle, 2-18% in blood. There was no obvious correlation between clinical picture and proportion of mutated mtDNA. In family B full MELAS syndrome appeared only in the third generation, but the mutation was also detected in muscle of asymptomatic individuals of the first and second generation. The proportion of mutated mtDNA in blood, and to a lesser extent in muscle, correlated with the severity of the clinical presentation. The MELAS mutation is consistently detected in all asymptomatic maternal relatives of MELAS patients. We conclude that different clinical presentations of mitochondrial encephalomyopathy may coexist in the same family, and correlation between clinical severity and molecular abnormality is not always recognizable. Presence of the MELAS mutation in muscle and blood is a necessary but not sufficient condition for the expression of the typical MELAS phenotype.

The authors report the case of a 25-year-old man who presented with a 4-year history of progressive glossolaryngeal paralysis. Operation through the right laterocervical region allowed complete removal of a neurofibroma involving the 10th and 12th nerves at their crossing below the nodose ganglion.

Forty-nine subjects were treated, 39 suffering from common migraine 10 from tensive vascular headache, for a period of 90 days, with an oral dose of 15 mg twice daily. The product was found to be efficacious in 71% of the common migraine cases, while unsatisfactory or nil results were obtained in the remaining 29%. In the tensive-vascular headache cases, efficacy was 40% compared to 60% unsatisfactory or nil results. Tolerance was good in 43 cases, while transient digestive disorders (nausea and vomiting) occurred in 6; in 2 cases the treatment had to be withdrawn for allergic erythema. The results demonstrate that the drug is indicated in cases of common migraine, while it does not appear to significantly influence the course of attacks of tensive-vascular headache.

Vascular neurologists in daily clinical practice may encounter patients taking rivaroxaban or patients who may benefit from its use. In this paper, we review the current clinical indications, contraindications, and clinical management guidelines for rivaroxaban while providing a special focus on neurological aspects and expert opinions on rivaroxaban therapy management in various situations that a neurologist may encounter when treating patients with an ischemic stroke (including those requiring intravenous or intra-arterial reperfusion therapy) and patients with an intracerebral hemorrhage. Since data from clinical trials and real-life data are missing in some clinical situations, strong recommendations are not always available. Nevertheless, practical guidelines should be adopted to maximize benefits from this oral anti-coagulant.

More than 60 pathogenic mutations have been reported up to now and prominent phenotypic variability within and among affected kindreds has been described. We have studied an Italian family with clinical evidence of dementia, and here we report detailed clinical records, imaging, sequential neurological examinations, cognitive assessments, and genetic analysis of three affected members of the same generation. Genetic analysis revealed the presence of the null mutation IVS6 + 5_8delGTGA in GRN, leading to haploinsufficiency, as documented by mRNA analysis. The mutation is associated with wide variation of the clinical phenotype, ranging from FTD to Alzheimer's disease and to a rapidly-progressive dementia. In summary, the patients of this kindred showed highly variable clinical features that do not have a close correspondence with the pattern of the cer...

All patients showed a marked deficit in executing intentions for future actions under all the given constraints. The deficit extended to both time- and event-based intentions. The analysis of errors showed somewhat different patterns and some dissociations with evidence for selective preservation or damage to specific components involved in prospective remembering. These patients, in fact, may fail because of a difficulty in taking into account all given constraints or in activating stored intentions and in forming intentions or in remembering the content of the actions. Time- and event-based tasks seem to show different sources of errors also in the same patient.

Selective deficits affecting different levels of the recognition processing were found; impaired recognition abilities were also influenced by selective task requirements, which resulted either in facilitatory or constraining effects on patients' performance. A theoretical model of object recognition (Humphreys & Riddoch, 1987) was taken into account to explain patients' performance. Further, the role of specific components of visual processing was evidenced in explaining the performance of patients affected by HSVE.
