Genes involved in familial dystonia syndromes (DYT genes) are ideal candidates for investigating whether common genetic variants influence the susceptibility to sporadic primary dystonia. To date, there have been few candidate gene studies for primary dystonia and only two DYT genes, TOR1A and THAP1, have been assessed. We therefore employed a(More)
Familial periodic cerebellar ataxia (FPCA) is a heterogeneous group of rare autosomal dominant disorders characterized by episodic cerebellar disturbance. A potassium-channel gene (KCNA1) has been found to be responsible for one of its subgroups, familial periodic cerebellar ataxia with myokymia (FPCA/+M; MIM 160120). A different subgroup that is not(More)
A 60-year-old woman with a typical history of fatal familial insomnia (FFI) had FFI proven by histologic examination and molecular testing. Her son, who died at the age of 20 in 1978, had a rapidly progressive dementing illness without reported insomnia. He carried the characteristic mutation for FFI and is the youngest patient reported with this condition.
The advent of deep brain stimulation (DBS) has been an important advance in the treatment of Parkinson's disease (PD). DBS may be employed in the management of medication-refractory tremor or treatment-related motor complications, and may benefit between 4.5% and 20% of patients at some stage of their disease course. In Australia, patients with PD are(More)
The language profile of a group of 18 Alzheimer patients is documented and their performance on a standard aphasia test battery compared to a group of institutionalized, nonneurologically impaired control subjects matched for age, sex, and educational level. The Alzheimer patients scored significantly lower than the controls in the areas of verbal(More)
Recent whole genome association studies provided little evidence that polymorphisms at the familial Parkinsonism loci influence the risk for Parkinson's disease (PD). However, these studies are not designed to detect the types of subtle effects that common variants may impose. Here, we use an alternative targeted candidate gene approach to examine common(More)
Two patients had a steadily progressive disorder of higher cortical function dominated by the early development of cortical visual deficits. In one, a right visual inattention progressed over a period of 2 years to a complete right homonymous hemianopia and relative left inferior quadrantanopia. In the second case, blind in the left eye for unrelated(More)
Motor and non-motor fluctuations are well known sequelae of dopaminergic therapies for Parkinson's disease (PD), particularly during the advanced stages. However, the prevalence of fluctuations early in the treatment course has been less well recognised and may be missed clinically if not specifically probed. We examined the used of a survey for this(More)
1. This study examined the ability of a bioimpedance method to detect the delay in gastric emptying which occurs during attacks of migraine. 2. In 64 non-migraineur control patients and 46 migraine patients outside an attack, gastric emptying rates were within the predicted normal range. 3. In contrast, rates in 14 migraineurs during 20 attacks were delayed(More)
