OBJECTIVES To report an association of myelin-oligodendrocyte glycoprotein (MOG) antibodies with aquaporin-4 (AQP4) antibody-seronegative neuromyelitis optica (NMO) and neuromyelitis optica spectrum disorder (NMOSD) in adults. METHODS We describe the clinical and serologic features of 4 adult patients with an NMO/NMOSD phenotype who had antibodies to MOG.(More)
IMPORTANCE While advances have been made in characterizing the C9ORF72 clinical phenotype, the hallmark features that discriminate between carriers and noncarriers remain unclear. OBJECTIVES To determine the frequency of the C9ORF72 mutation in a frontotemporal dementia (FTD) cohort and to define the clinical, neuropsychological, behavioral, and imaging(More)
BACKGROUND AND PURPOSE Behavioural-variant frontotemporal dementia (bvFTD) and Alzheimer's disease (AD) patients experience behavioural and emotion recognition alterations, yet understanding of how socioemotional processing is affected with disease progression is minimal. Additionally, evidence suggests that bvFTD patients with limited brain atrophy on(More)
It is increasingly recognized that metabolic factors influenced by eating behavior, may affect disease progression in neurodegeneration. In frontotemporal dementia (FTD), which shares a significant overlap with Amyotrophic lateral sclerosis (ALS), patients are well known to develop changes in eating behavior. Whether patients with pure ALS and those with(More)
PURPOSE Use of antiepileptic drugs in pregnancy is associated with congenital malformations and developmental delay. Previous studies have suggested that women who have had one child with a congenital malformation are at increased risk of having other children with malformations. We sought to confirm the magnitude of risk in a large cohort drawn from the(More)
The typical presentation of semantic dementia is associated with marked, left predominant anterior temporal lobe atrophy and with changes in language. About 30% of individuals, however, present with predominant right anterior temporal lobe atrophy, usually accompanied by behavioural changes and prosopagnosia. Here, we aimed to establish whether these(More)
Neurodegeneration refers to a heterogeneous group of brain disorders that progressively evolve. It has been increasingly appreciated that many neurodegenerative conditions overlap at multiple levels and therefore traditional clinicopathological correlation approaches to better classify a disease have met with limited success. Neuronal network disintegration(More)
SEE FINGER DOI101093/AWW312 FOR A SCIENTIFIC COMMENTARY ON THIS ARTICLE: Abnormal eating behaviour and metabolic parameters including insulin resistance, dyslipidaemia and body mass index are increasingly recognized as important components of neurodegenerative disease and may contribute to survival. It has previously been established that behavioural(More)
IMPORTANCE A gap in the literature exists regarding progression in behavioral variant frontotemporal dementia (BVFTD). Guidance is needed concerning markers that will enable clinicians to discriminate FTD more effectively from phenocopies and to identify factors that determine progression and thereby prognosis. OBJECTIVES To observe longitudinal outcomes(More)
The recently discovered hexanucleotide repeat expansion, C9ORF72, has been shown to be among the most common cause of familial behavioural variant frontotemporal dementia (bvFTD) and to be present in a significant minority of apparently sporadic cases. While mounting evidence points to prominent episodic memory dysfunction in bvFTD cases, recent reports(More)
