We studied auditory brainstem responses (ABRs) of sixteen infants and children with brain damage after anoxic accidents due to near-suffocation or near-drowning. The patients manifested cerebral palsy, mental retardation and/or epilepsy and showed poor responses in the behavioral audiometry. Auditory brainstem responses were abnormal in five of the patients in ...

Neurosurgery can be complicated by the clinical situation commonly referred to as "tight brain," in which the brain presses against the inner table of the skull or protrudes through the craniotomy site. We report here a retrospective study of 32 patients who had undergone elective craniotomy for resection of supratentorial ...

The juvenile neuronal ceroid-lipofuscinosis (JNCL) is a recessively inherited progressive encephalopathy. We studied 21 JNCL patients with a duration of illness of 1 to 17 years by 99mTc-HM-PAO single photon emission computed tomography (SPECT) and correlated the findings with clinical parameters. All patients had at least one hypoperfused brain area, ...

A significant minority of patients who have sustained a mild traumatic brain injury (MTBI) may exhibit persistent disability. There have been few attempts to describe and evaluate the effectiveness of neurorehabilitation for these patients. We conducted a retrospective analysis of the results of a neuropsychological rehabilitation programme for 20 patients ...

Twenty-six patients with stable non-alcoholic cirrhosis and normal neurological examination were investigated by brain MRI (inversion recovery sequences) and compared with 16 controls. Brain MRI findings were correlated with the clinical and metabolic status of the patients and analysis of variance and, when necessary, co-variance was performed. Five of the ...

Although both morphologic cerebral damage and cognitive dysfunction are known to occur in patients on chronic hemodialysis (CHD) their extent and possible relation have been rarely studied. We therefore performed magnetic resonance imaging of the brain and neuropsychological testing in 30 consecutive CHD patients (mean age 58 years; range 37-69) ...

OBJECTIVE: To evaluate the regional cerebral metabolic involvement; the relationships among regional brain metabolism, clinical features, and quantitative measures of disease severity; and the patterns of brain involvement that can be related to the different types of onset: striatonigral degeneration vs olivopontocerebellar atrophy. DESIGN: Fludeoxyglucose F 18 positron emission tomography ...

Chronic alcohol abuse is responsible for several organic brain disorders. However, even the most characteristic of them are largely underdiagnosed by routine procedures. Therefore, there is need for sensitive, noninvasive and low-cost diagnostic procedures. 99m-Tc-HMPAO-SPECT could be an interesting candidate in this indication, because it estimates the distribution of the ...

We examined immunohistochemically 123 autopsy brains from patients aged between 30 to 59, who died as a result of malignant neoplasms. Using antiserum to amyloid beta protein (A beta), we found that cerebral A beta deposits began in the subjects' fifth decade; its prevalence was 0%, 9.8% and 21.5% in ...

A patient who showed Lilliputian hallucinations and negative hallucinations in the course of probable disseminated encephalomyelitis is described. At the age of 14 years the patient experienced a transient, flaccid paresis of the right leg. Eighteen years later she suddenly developed paranoid-hallucinatory symptoms accompanied by atypical visual hallucinations. She did ...

Although recently survival of some medulloblastoma patients increased remarkably, it remains a serious diagnosis in others. In order to predict the postoperative prognosis in patients treated for medulloblastoma, a new staging, scoring and grading system was developed. Sixty-six patients operated on microsurgically between 1975 and 1990 at a single neurosurgical ...

Brain magnetic resonance imaging (MRI) was performed in 17 late-detected PKU patients (aged 2.8-25 years). Twelve subjects had been treated late (0.7-4.5 years), and 5 not at all. Four were still on diet when the study was performed. Mental development was normal in 4 subjects, mildly retarded in 6, and ...

Imitation of meaningless gestures was examined in patients with left brain damage (LBD), right brain damage (RBD) and controls. In addition to imitation on the own body, patients were asked to replicate the gestures on a life-sized mannikin. Manual dexterity was assessed by manipulation of beads, and general visuospatial abilities ...

50 patients who had sustained a traumatic brain injury were given complete neuropsychological assessments between 0.5 and 4.0 years after the incident; 62% of these patients reported that episodes of a "sensed presence" (left side: 71%; right side: 19%; both: 10%) had occurred. Sensed presences along the left side were ...

BACKGROUND: It is known that automatic breathing is controlled by centres in the lower brain stem, whereas volitional breathing is controlled by the cerebral cortical centres. In hemiplegia, lesions above the brain stem result in paralysis of limb muscles. This study was performed to determine whether the diaphragm might also ...

Exposures to neurotoxic chemicals such as pesticides, glues, solvents, etc. are known to induce neurologic and psychiatric symptomatology. We report on 41 patients--16 young patients (6 males, 10 females, age 34 +/- 8 yrs.) and 25 elderly patients (9 males, 16 females, age 55 +/- 7 yrs). Fifteen of them ...

BACKGROUND: Conjugate eye deviation (CED) in patients with acute supratentorial lesions is generally directed ipsilateral to the lesioned hemisphere. Incidentally, CED occurs to the contralateral side. We report five new cases and review previously published reports to elucidate the lesion responsible for and the mechanism underlying this phenomenon. CASE DESCRIPTIONS: ...

Magnetic brain stimulation was performed on 24 patients with Wilson's disease (WD). Responses to the right and left first dorsal interosseus muscle (FDI) and to the right and left tibialis anterior muscle (TA) were analysed. In 45% of the patients prolonged central motor conduction times (CCTs) to the FDIs were ...
