In a preliminary study, the effects of ventroposterior medial pallidotomy were evaluated in five patients with advanced Parkinson's disease in whom medical therapy had failed. The mean age was 67.0 +/- 5.6 years, and the mean Hoehn and Yahr stage when "off" was 3.9 +/- 1.3. Three patients received unilateral pallidotomies; two of these received another pallidotomy after 8 weeks. Two other patie...
INTRODUCTION A large percentage of patients with Parkinson's disease (PD) develop motor fluctuations, dyskinesias, and severe non-motor symptoms within 3 to 5 years of starting dopaminergic therapy, and these motor complications are refractory to treatment. Several authors refer to this stage of the disease as advanced Parkinson's disease. OBJECTIVE To define the clinical manifestations of ad...
The ability of L-dopa to relieve the motor impairments in Parkinson's disease patients declines over time, and side-effects, such as dyskinesias, appear--limiting the use of the drug in the advanced stage of the disease. Serotonergic neurons are able to convert L-dopa to dopamine and to store this neurotransmitter in synaptic vesicles. This peculiarity might be very important in the advanced di...
Secondary paroxysmal dyskinesias (PxD) have been previously reported in patients with multiple sclerosis, lacunar infarcts, head trauma, metabolic disorders such as hyperglycaemia, hypocalcaemia, migraine and central nervous system (CNS) infections. The causative lesions typically involve the basal ganglia structures, medulla and rarely the spinal cord. We report two patients who presented with...
A retrospective examination of lethargic encephalitis finds many parallels with neuroleptic effects. The encephalitis, like the neuroleptics, produced an acute continuum of cognitive disorders from emotional indifference through apathy and onto a rousable stupor. It also produced similar acute dyskinesias, including akinesia, akathisia, dystonia, oculogyric crises, and tremors. The encephalitis...
