Functional neuroimaging and presenting psychiatric features in frontotemporal dementia.
Frontotemporal dementia (FTD) is a behavioural syndrome caused by degeneration of the frontal and anterior temporal lobes. Behavioural disturbances include psychiatric features. Whether patients with FTD present with psychiatric features varies with the initial neuroanatomical variability of FTD. ⋯ Patients with FTD may present with psychiatric changes distinct from the behavioural diagnostic criteria for this disorder. Early temporal involvement is associated with frivolous behaviour and right temporal involvement is associated with emotional disturbances. In contrast, those with right frontal disease may present with alterations in non-verbal behaviour.

Insulin-like growth factor I promoter polymorphism, risk of stroke, and survival after stroke: the Rotterdam study.
Low levels of insulin-like growth factor I (IGF-I) predispose to atherosclerosis and may therefore increase the risk of stroke. Low levels have also been found to influence the outcome of cardiovascular and cerebrovascular disease. A polymorphism in the promoter region of the IGF-I gene influences IGF-I levels. Non-carriers of the 192 bp allele have lower levels of IGF-I compared with 192 bp allele carriers. We studied the IGF-I polymorphism in relation to the risk of stroke and survival after stroke. ⋯ Our study suggests that IGF-I is a significant determinant of survival after stroke.

Case ReportsLeigh syndrome caused by mutations in the flavoprotein (Fp) subunit of succinate dehydrogenase (SDHA).
Detailed clinical, neuroradiological, histological, biochemical, and genetic investigations were undertaken in a child suffering from Leigh syndrome. The clinical symptoms started at age five months and led to a severe progressive neurodegenerative disorder causing epilepsy, psychomotor retardation, and tetraspasticity. ⋯ Sequencing of SDHA revealed compound heterozygosity for a nonsense mutation in exon 4 (W119X) and a missense mutation in exon 3 (A83V), both absent in normal controls. In six additional patients--five with Leigh or Leigh-like syndrome and one with neuropathy and ataxia associated with isolated deficiency of complex II--mutations in SDHA were not detected, indicating genetic heterogeneity.

Arterial hypertension as risk factor for spontaneous cervical artery dissection. A case-control study.
Because of the presumed non-atherosclerotic pathogenesis, the potential link between spontaneous cervical artery dissection (sCAD) and common risk factors for atherosclerosis has never been investigated systematically. Therefore, this prospective, multicentre, case-control study compared the frequency of tobacco use, hypertension, diabetes mellitus, and hypercholesterolaemia among a group of consecutive patients with sCAD (n = 153), a group of patients with ischaemic stroke, not related to CAD (non-CAD), and a group of controls. ⋯ Hypertension was also significantly associated with the subgroup of patients with sCAD and cerebral infarction (OR, 1.94; 95% CI, 1.01 to 3.70; p = 0.045), particularly when involving the vertebral arteries (OR, 2.69; 95% CI, 1.20 to 6.04; p = 0.017). These findings might help define the spectrum of pathogenic conditions predisposing to sCAD and provide information to help investigate the combined effect of such susceptibility factors in future studies.
