Autosomal Dominant Nocturnal Frontal Lobe Epilepsy (ADNFLE) is associated in some kindreds with mutations in the genes encoding the alpha 4 or beta 2 subunits of the neuronal nicotinic acetylcholine receptor (nAChR). Functional characterisation of the described ADNFLE mutations in oocyte preparations has produced conflicting results, with some studies(More)
In this prospective study of 34 patients with Parkinson's disease, measurements of the short duration levodopa motor response have been performed in defined off states at 3 yearly intervals over a mean period of 11.4 years from the point of commencement of levodopa treatment. Twenty-two patients were still available for study; 10 had died and 2 were lost to(More)
Neuronal nicotinic acetylcholine receptors are ligand-gated ion channels that subserve a range of functions in the brain and peripheral nervous system. They are pentamers variously composed of α(α2− α10) and β subunits ( β2− β4). Pharmacological and ligand-binding studies have shown that the different subunits vary in their distribution and channel(More)
Thirty-four patients with Parkinson's disease were followed for a mean period of 8 years from the time of initiation of levodopa medication. Levodopa response was charted from the starting point of pharmacological treatment to give a longitudinal point of view of the changes that evolve as the disease progresses. Objective measurements of the motor response(More)
Galanin is a widely-distributed neuropeptide that acts as an endogenous anticonvulsant. We have recently generated a galanin receptor type 1 knockout mouse (Galr1(-/-)) that develops spontaneous seizures. Our aim here was to characterize the seizures by making electroencephalogram (EEG) recordings from this animal, and also to elucidate the cellular basis(More)
The genetic basis of a number of epilepsy syndromes has been identified but the precise mechanism whereby these mutations produce seizures is unknown. Three mutations of the alpha(4) subunit of the neuronal nicotinic acetylcholine receptor (nAChR) have been identified in autosomal dominant nocturnal frontal lobe epilepsy. In vitro studies of two mutations(More)
It is well established that chemokines have a major role in the stimulation of cell movement on extracellular matrix (ECM) substrates. However, it is also clear that ECM substrates may influence the ability of cells to undergo migration. Using the migration chamber method, we assessed the migratory response of human embryonic kidney-293 (HEK) transfectant(More)
Thirty-four patients have been studied from the time of initiation of pharmacological treatment in a long-term prospective study of levodopa effects and disease progression in Parkinson's disease. Objective motor scoring of the response to levodopa in defined off states was performed every 3 years. The mean time from the initiation of levodopa treatment to(More)
In this prospective study of 34 patients with Parkinson's disease (PD), measurements of the short duration levodopa motor response have been performed every 3 years in defined off states. The mean time from initiation of levodopa treatment was 14.8 years, and 17 patients survived to the latest assessment stage. Off phase motor function worsened at a yearly(More)

INTRODUCTION It is important to understand how the rate of motor progression in PD relates to dopaminergic treatment. METHODS The methods for this study comprised prospective defined off state measurements of the levodopa response at 3-year intervals over a mean 13.3-year period in 34 patients enrolled before treatment initiation. RESULTS Despite(More)
