The electroencephalograms (EEGs) of 22 patients suffering from hereditary DRPLA were studied. Epileptoform patterns were observed in 14 patients (63.6%) with epileptic seizures. The epileptoform patterns most frequently observed were those atypical spike-wave complexes. Slow wave bursts were seen in 18 patients (81.8%). Photosensitivity was revealed in six (27.3%) patients, ...

Significant improvement of mental status was noted with amantadine therapy in three patients in whom autopsy subsequently showed Alzheimer's disease. Two patients showed a dramatic improvement during the treatment. Their mute, immobile states were reversed and they were able to speak a few coherent words. Their mental status deteriorated when ...

We performed a retrospective study of auras that occurred independently of complex partial seizures in patients undergoing continuous EEG monitoring with stereotactically implanted depth electrodes placed in mesiotemporal structures. Forty of 54 patients had a history of independent auras, and 32 of these individuals had independent auras while being monitored. ...

A retrospective study was carried out in 147 patients who had been found to have periodic lateralized epileptiform discharges (PLEDs). Clinical, laboratory, radiological, and pathological correlation was performed for all patients. As in previously published works, we found a high correlation with cerebrovascular accidents in our population. A large number ...

This study explores the relationship between the results of tests of dementia and the EEG findings in 94 demented patients of different etiologies. Abnormal EEGs were found in 83% of all patients, usually diffuse slow wave abnormalities, the degree of which correlated very well with the Modified Hachinski test. Only ...

A retrospective analysis was done of the management and the results of treatment in 158 trypanosomiasis patients seen in a rural hospital in Tanzania during 1985. The distribution of cases in the population and during the year reflected an endemic situation. 109 patients (68.9%) were in the meningoencephalitic (ME) stage ...

The reliability of selective shunting based on computerized electroencephalographic (EEG) monitoring has not been addressed. In this study, 103 carotid endarterectomies were performed with selective shunting based on a two-channel computerized EEG monitor that processed the on-line, raw electroencephalogram (EEG) to produce a compressed spectral array (CSA). Ischemic EEG events ...

A clinical, neurological and electroencephalographic investigation was undertaken in 29 previously cytogenetically verified hemizygous males with the fra(X) form of mental retardation (age range 3.5 to 59 years); in addition, 6 heterozygous females were examined. All male patients displayed the known physical aspects of this syndrome together with associated abnormalities ...

Two patients with acquired dysgraphia were reported. The patients' performance in various written and oral spelling tasks converge in support of the hypothesis that they have selective damage, within the spelling system, to the Graphemic Buffer. Although the patients present with comparable patterns of error types, they differ in the ...

20 patients with hyperthyroidism were observed with repeated EEG measurements before and during treatment (ObsidanR; MethimazolR). 17 patients, before starting antithyroid therapy, had slight to moderate EEG abnormalities. A prevalence for moderate disturbances occurred for patients with a higher degree of hyperthyroidism. The dominant EEG frequency was higher than in ...

Forty eight comatose children had electroencephalograms (EEG) recorded during the acute phase of their illnesses. These were classified according to a simple grading system and the findings correlated with the presence of seizures, deep coma, minimum cerebral perfusion pressure, and eventual neurological outcome. Serial EEGs proved important, particularly when slow ...

Interictal EEG records of Nigerian epileptic patients living in Lagos and clearly diagnosed as having grand mal epilepsy were compared with those of British epileptic patients with a similar diagnosis. Interictal EEG abnormalities (spike and wave discharges, (SW), photoparoxysmal discharges (PPD), and nonspecific changes) were significantly less common in Nigerian ...

Low alpha frequency (less than 10.2 Hz) occurred more frequently in medication-free schizophrenic patients than in normal control subjects, as determined by quantitative EEG analysis. Furthermore, those patients with low alpha frequency had significantly larger lateral ventricles, as measured by CT scan, than did other schizophrenic patients (mean +/- SD ...

The magnetoencephalogram (MEG) and electroencephalogram (EEG) were measured during interictal epileptic spikes in nine patients with complex partial seizures. The MEG localization estimates were compared with localizations by intraoperative cortical electrodes, subdural electrodes, stereotaxic depth electrodes, anatomic imaging, postoperative pathologic analysis, and postoperative follow-up. In all patients, MEG localization estimates ...

Positive sharp waves occur in a variety of neurogenic, myogenic, and metabolic disorders. Although not synonymous with denervation, their presence is usually associated with some type of pathology. The authors found only one reported series of patients who had diffuse insertional positive waves but no demonstrable underlying disease. There were ...

Spectral EEG analysis has been successfully utilized in previous studies on migraine patients. The aim of our study was to evaluate, by means of EEG mapping, potential correlations between the efficacy of flunarizine treatment in migraine patients and the EEG pattern recorded after chronic flunarizine therapy. Flunarizine was found to ...

Fifteen patients with fibromyalgia syndrome were given EMG-BFB (biofeedback) training sessions because of persistent aches after one year of monthly courses of NSAID. A long-lasting clinical benefit was observed in 56%. The improvement was found in those without overt psychopathological disturbances. In fact, a subgroup of clinically depressed patients responded ...

Evolution of both clinical and EEG abnormalities was analyzed in 20 (16 pathologically confirmed) patients suffering from subacute spongiform encephalopathy with periodic paroxysmal activities (PPA) on the EEG. Illness duration was less than 4 and greater than 17 months in 65% and 10% of cases, respectively. All data but EEG ...
