The aim of the study described here was to analyze findings in 15 cases who were admitted with nonconvulsive status epilepticus (NCSE) and whose EEGs featured atypical triphasic waves (ATWs). We also investigated whether ATWs are useful for diagnosing this condition. Mental status was assessed, and EEGs were recorded during/after the antiepileptic drug(More)
Even though stroke is known to be a common cause of status epilepticus (SE), the types of stroke or SE that may be associated are not yet clearly defined. The aims of this study were to assess the timing and type of SE in stroke patients and to observe the effects of stroke and the type of SE on the response to treatment and mortality. From May 1998 to May(More)
Infectious-immunogenic mechanisms have been proposed for the pathogenesis of the syndrome of transient headache and neurological deficits with cerebrospinal fluid lympho-cytosis (HaNDL) [1]. To investigate this assumption, we performed immunohistochemistry and Western blot studies with sera and cerebrospinal fluid (CSF) of two HaNDL patients. Serum and CSF(More)
The aim of the study is to analyze diffusion tensor imaging (DTI) characteristics of the Guillain-Mollaret triangle (GMT) in patients with hypertrophic olivary degeneration (HOD) and to investigate their correlation with previously reported histopathology. DTI was performed in 10 patients diagnosed with HOD. Fractional anisotropy, apparent diffusion(More)
BACKGROUND AND PURPOSE During the hyperacute phase of stroke, multiple hypointense vessels were identified specifically in the ischemic territory on gradient-echo T2*-weighted MR images (GRE-T2* WI) at 3T. The area was named a "region of multiple hypointense vessels (RMHV)." The aim of this study was to assess the usefulness of RMHV for the diagnosis of(More)
The aim of this study was to evaluate the computed tomography (CT) and magnetic resonance imaging findings (MRI) of asymptomatic remote cerebellar hemorrhage (RCH) at the preoperative, early postoperative, and postoperative period. A total of 983 consecutive adult patients who underwent supratentorial craniotomies were included in the study. The ethics(More)
Prolonged status epilepticus may directly cause selective neuronal necrosis due to excitotoxic mechanisms, as observed in experimental models and described in case reports. A 36-year-old woman presented with right hemiplegia and aphasia following a generalised tonic-clonic status epilepticus of two hours duration. Accompanying serial MRI with advanced(More)
BACKGROUND The location of the primary motor cortex can be detected in healthy adults using the findings of 'T2 hypointensity' and the 'double layer sign' on 3 T diffusion-weighted imaging. The aim of this study was to assess whether ischemic involvement of the primary motor cortex can be identified on 3 T diffusion-weighted imaging within six-hours after(More)
BACKGROUND The aim of this study was to investigate aortic atheromas in stroke subgroups. METHODS Two hundred consecutive subjects had acute ischemic stroke confirmed by diffusion-weighted imaging (DWI) (195 cases) or computerized tomography (5 cases). Multidetector computed tomographic angiography (MDCTA) (16- or 64-slice) was used to detect(More)
Nonconvulsive status epilepticus (NCSE) is an enduring epileptic condition characterized by alteration in consciousness and continuous ictal discharges on the EEG. Various etiologies have been reported. We describe the case of a 66-year-old woman with altered mental status who was diagnosed with NCSE. A workup to explain the etiology revealed tuberculous(More)
