background: carbon monoxide (co) poisoning may lead to hypoxic/anoxic injury and eventually ischemic encephalopathy. magnetic resonance imaging (mri) has a well-recognized role in assessment of the severity of brain damage caused by co poisoning. in this study, we aimed to present and analyze the structural abnormalities in the brain mri and especially in diffusion weighted mri (dwi) images in ...
BACKGROUND Chronic deep brain stimulation (DBS) of the globus pallidus internus (GPi) has become an established treatment for dystonia. While bradykinetic symptoms may occur on chronic stimulation, the appearance of hyperkinetic movements has not been well characterized. CASE REPORT We report on the development of hyperkinesias after more than 10 years of GPi DBS. DISCUSSION Hyperkinesias m...
We have reported previously that striatal projection neurons are differentially affected in the course of Huntington's disease, and in a prior patient report we noted that differential loss of striatal projection neurons occurs also in patients with presymptomatic Huntington's disease. Striatal neurons projecting to the external segment of the globus pallidus or the substantia nigra show eviden...
Alexithymia refers to a person's inability to identify and describe feelings. We present a patient who developed alexithymia after carbon monoxide poisoning following a suicide attempt by burning charcoal in an enclosed space. Brain computed tomography revealed bilateral globus pallidus hypoxic lesions. Because of the time frame and the presence of brain structural lesions, the alexithymia in t...
Positron emission tomography with O-15-labeled water was used to study at rest the neurophysiological effects of bilateral external globus pallidus (GPe) deep brain stimulation in patients with Huntington's disease (HD). Five patients were compared with a control group in the on and off states of the stimulator. External globus pallidus stimulation decreased neuronal activity and modulated cere...
Three patients with sporadic amyotrophic lateral sclerosis (ALS) presented with a history of backward falls. Impaired postural reflexes and retropulsion accompanied clinical features of ALS. Hypokinesia, decreased arm swing, and a positive glabellar tap were noted in two of these three patients. Cognitive impairment, tremor, axial rigidity, sphincter dysfunction, nuchal dystonia, dysautonomia, ...
