1/49. Biofeedback training to overcome poststroke foot-drop.The technique has exciting potential for elderly hemiplegic patients, even those who are confined to a nursing home. There are limiting factors, of course; the method is time-consuming and the initial outlay for equipment is high. But the rewards can be well worth the time, effort, and cost involved. The recovery potential of some geriatric patients after a cerebrovascular accident may seem bleak because of multiple disabilities, e.g., paralysis, delayed reflexes, aphasia. Fortunately, these disorders do not necessarily decree failure of biofeedback training. Neither does advanced age. The strongest component in success is motivation. A case in point is the 82 year old woman described here who had been hemiparetic for seven years. With biofeedback training, she gained--and maintained--muscle strength.- - - - - - - - - - ranking = 1keywords = paralysis (Clic here for more details about this article) |
2/49. Primary central nervous system lymphoma presenting with a parkinsonian syndrome of pure akinesia.The incidence of primary central nervous system lymphoma (PCNSL), once a rare tumour, has risen significantly in both immunocompetent and immunosuppressed patients. Although infiltration of the basal ganglia is not uncommon in PCNSL, extrapyramidal movement disorders are generally not recognised as a mode of clinical presentation of this type of cerebral tumour. We present the unusual case of a 75-year-old man who developed a parkinsonian syndrome of "pure akinesia" due to autopsy-confirmed PCNSL primarily involving the globus pallidus bilaterally. Parkinsonism due to bilateral pallidal lesions is known but rare, and such cases help in the understanding of basal ganglia function with regard to akinesia and freezing.- - - - - - - - - - ranking = 55880.346207175keywords = parkinsonian (Clic here for more details about this article) |

Corticobasal ganglionic degeneration with Balint's syndrome.Corticobasal ganglionic degeneration (CBGD) is a neurodegenerative dementia characterized by asymmetric parkinsonism, ideomotor apraxia, myoclonus, dystonia, and the alien hand syndrome. This report describes a patient with CBGD who developed Balint's syndrome with simultanagnosia, oculomotor apraxia, and optic ataxia.- - - - - - - - - - ranking = 13944.948537428keywords = parkinsonism (Clic here for more details about this article) |
4/49. Clinical report of three patients with hereditary hemochromatosis and movement disorders.neurologic manifestations are rarely described in hereditary hemochromatosis (HH). We describe three patients with HH and movement disorders. Patient 1, a 69-year-old man, had a 13-year history of disabling cerebellar syndrome, action tremor and myoclonus, and secondary dementia. Patient 2 was a 40-year-old man with a 9-year history of cerebellar syndrome, head and arm tremor, and cervical dystonia. Patient 3, a 75-year-old woman, had a 5-year history of rapidly disabling parkinsonian syndrome unresponsive to levodopa. The diagnosis of HH was established in the three patients by iron tests, evidence of a C282Y mutation, and, in two patients, by liver biopsy. High-field T2-weighted magnetic resonance imaging showed hyperintense signals in hemispheric white matter in patient 1, cerebellar atrophy in patient 2, and cerebellar and cerebral atrophy in patient 3 and no significant hypointense signals in the three patients. Phlebotomies and symptomatic treatments did not change the course of the disease. Our cases are compared with the five previously reported observations of HH with movement disorders. This rare association is one cause of the chronic acquired non-Wilsonian hepatocerebral degeneration syndromes and represents a separate entity from aceruloplasminemia. The pathophysiologic mechanism of movement disorders in HH is unresolved. No hepatic insufficiency and portosystemic encephalopathy is evidenced in our cases, whereas the putative role of abnormal iron load remains to be ascertained. HH should be investigated more systematically in patients with movement disorders.- - - - - - - - - - ranking = 11176.069241435keywords = parkinsonian (Clic here for more details about this article) |
5/49. Involuntary movements after anterior cerebral artery territory infarction.BACKGROUND AND PURPOSE: patients with anterior cerebral artery territory infarction presenting with involuntary movements have rarely been described in the literature. CASE DESCRIPTIONS: The author reports 9 such patients: 3 with asterixis, 5 with hemiparkinsonism (tremor, rigidity, hypokinesia), and 1 with both. Asterixis developed in the acute stage in patients with minimal arm weakness, whereas parkinsonism was usually observed after the motor dysfunction improved in patients with initially severe limb weakness. Asterixis correlated with small lesions preferentially involving the prefrontal area; parkinsonism is related to relatively large lesions involving the supplementary motor area. CONCLUSIONS: anterior cerebral artery territory infarction should be included in the differential diagnosis of asterixis and hemiparkinsonism.- - - - - - - - - - ranking = 55779.794149712keywords = parkinsonism (Clic here for more details about this article) |
6/49. Acute posttraumatic spinal cord herniation. Case report and review of the literature.Transdural herniations of the spinal cord are rare, and those occurring acutely after a spinal cord injury (SCI) are particularly unusual. In this report, the authors present the case of acute posttraumatic spinal cord herniation in a patient who sustained severe polytraumatic injuries. The clinical manifestations were acute flaccid paralysis of the right leg and rapidly progressive sensorimotor deficits of the contralateral leg. The herniation was surgically reduced. Postoperatively left leg paralysis was completely resolved. The authors review the pertinent literature, and suggest that, with regard to another underlying pathophysiological mechanism, cases of acute posttraumatic spinal cord herniation should be differentiated from those "posttraumatic" cases in which herniation of the spinal cord occurs years or even decades after the traumatic event. To the best of the authors' knowledge, only one similar case has been previously reported. They conclude that acute posttraumatic spinal cord herniation should be included in the differential diagnosis of acute neurological deterioration after SCI.- - - - - - - - - - ranking = 2keywords = paralysis (Clic here for more details about this article) |
7/49. EEG characteristics in juvenile Huntington's disease: a case report and review of the literature.The clinical features of Juvenile Huntington's disease (J-HD) differ from those of the more common adult-onset form, and include cognitive decline, parkinsonism, myoclonus and seizures. A paucity of literature is available describing the electroencephalographic (EEG) findings. We describe the clinical and EEG characteristics of a patient with genetically confirmed J-HD. A review of previously published cases yielded EEG descriptions in only 23 patients whose disease onset was prior to the age of 32, and only 14 of these were prior to the age of 20. Epileptiform abnormalities were noted in 17 (74%), which was considerably more common than in the adult form. Generalized discharges were noted in nine, with six having polyspike and wave. The remainder had focal or multifocal epileptiform discharges. With genetic testing now available, refinement of the EEG data will be possible.- - - - - - - - - - ranking = 13944.948537428keywords = parkinsonism (Clic here for more details about this article) |
8/49. Unexpected movement disorders in neurosurgical practice: report of three cases.Hyperkinetic movement disorders may develop as a complication of stereotactic thalamotomy or pallidotomy. However, such movement disorders are uncommon after nonsterotactic intracranial operations. The authors report three cases of involuntary movement disorders unexpectedly developing after intracranial operations. The patients had undergone clipping of an internal carotid aneurysm, removal of an intracerebral hematoma, and resection of a tentorial meningioma. Two patients developed choreic movements and a dystonic posture of the unilateral upper extremity. One patient showed a tremor that had features of both parkinsonism and essential tremor. The symptoms of these patients were medically uncontrollable, and they were successfully treated with stereotactic ventrolateral thalamotomy.- - - - - - - - - - ranking = 13944.948537428keywords = parkinsonism (Clic here for more details about this article) |
9/49. Late-onset presentation of pyruvate dehydrogenase deficiency.Two brothers presented in their mid-forties with movement disorders including atypical parkinsonism, choreiform movements, stereotypies, ataxia and dysarthria. Both brothers showed putaminal lucencies on imaging and, in the proband, a deficiency of the pyruvate dehydrogenase complex (PDHC) was found on skin fibroblast assay.- - - - - - - - - - ranking = 13944.948537428keywords = parkinsonism (Clic here for more details about this article) |
10/49. Hemiballism and chorea in a patient with parkinsonism due to a multisystem degeneration.dyskinesias associated with dopaminergic treatment in idiopathic Parkinson's disease (PD) can be indistinguishable from those arising spontaneously in other conditions involving degeneration of, or damage to, the basal ganglia. However, those due to levodopa treatment of PD disappear on cessation of therapy. We report a patient with a clinical diagnosis of PD who, on levodopa treatment, developed hemiballism and chorea that were originally thought to be drug induced. However, the dyskinesias persisted despite stopping levodopa. Postmortem analysis showed a multisystem degeneration.- - - - - - - - - - ranking = 55779.794149712keywords = parkinsonism (Clic here for more details about this article) |
