The aim of this study was to compare the patterns cerebellar alterations associated with bipolar disease those induced by presence neurodegenerative pathologies clarify potential contribution affective disturbance. Twenty-nine patients affected disorder, 32 subjects pathologies, and 37 age-matched healthy underwent a 3T MRI protocol. A voxel-based morphometry analysis used show similarities dif...
BACKGROUND AND PURPOSE Determining language dominance with fMRI is challenging in patients with brain tumor, particularly in cases of suspected atypical language representation. Supratentorial activation patterns must be interpreted with great care when the tumor is in or near the presumed language areas, where tumor tissue or mass effect can lead to false-negative fMRI results. In this study, ...
Numerous studies have highlighted the possibility of modulating the excitability of cerebro-cerebellar circuits bi-directionally using transcranial electrical brain stimulation, in a manner akin to that observed using magnetic stimulation protocols. It has been proposed that cerebellar stimulation activates Purkinje cells in the cerebellar cortex, leading to inhibition of the dentate nucleus, w...
BACKGROUND AND PURPOSE Hemimegalencephaly is a rare but well-known congenital malformation with ipsilateral enlargement of the hemicerebrum. However, very little is known about changes in structures outside the involved hemisphere in patients with this condition. We investigated morphologic abnormalities occurring outside the affected hemisphere by MR imaging in a large series of patients with ...
Abstract Background: Cerebellar tumors are considered as clinically significant intracranial neoplasms and acknowledgment of their epidemiological characteristics tends to be essential. The present study was conducted in order to determine the prevalence and types of their cerebellar tumors in Shohada-e-Tajrish Hospital between 2006-2014. Materials and Methods: In the current observational...
Objective(s): The present study aims at examining the motor coordination performance, serum and cerebellar estrogen, as well as ERβ levels, of ovariectomized rats (as menopausal model) following regular exercise. Materials and Methods:Ten female Sprague Dawley ratsaged 12 weeks old were randomly divided into two groups; all of which underwent ovariectomy. The first group was treated with regula...
BACKGROUND Cryptococcal meningoencephalitis (CM) causes cerebral infarction, typically, lacunar infarction in the basal ganglia. However, massive cerebral infarction leading to death is rare and its pathophysiology is unclear. We report a case of CM causing massive cerebellar infarction, which led to cerebral herniation and death. CASE PRESENTATION A 56-year-old man who suffered from dizzines...
