Publication Open Access Presence of Status Epilepticus with Ebstein Barr Virus Encephalitis(2018-04-01T00:00:00Z) DENİZ, ÇİĞDEM; ASİL, Talip; BOLUKÇU, SİBEL; Zengin, S. Ulgen; DENİZ, ÇİĞDEM; ASİL, TALIP; BOLUKÇU, SİBELNeurological involvement, mostly in the form of meningoencephalitis or encephalitis, represents the leading cause of death in patients with infectious mononucleosis (EF). Central nervous system involvement usually occurs after the first 1 to 3 weeks of disease, although patients presenting with neurological signs and symptoms have been rarely reported. In this case presentation, our aim was to examine the association between acute Ebstein barr virus (EBV) infection and refractory myoclonic convulsions in a patient presenting with myodonic status.Publication Open Access Evaluation and follow-up of cognitive functions in patients with minor stroke and transient ischemic attack(2016-01-01) Deniz, Cigdem; Celik, Yahya; GULTEKIN, Tugce Ozdemir; BARAN, Gozde Eryigit; DENIZ, Cagla; Asil, TALİP; DENİZ, ÇİĞDEM; ASİL, TALIPBackground and purpose: We aimed to examine the incidence of cognitive impairment among patients with stroke, the associated risk factors, progression of the cognitive impairment, and the association between the localization of the lesion(s) as detected by magnetic resonance imaging and the affected areas of cognitive function. Methods: A total of 40 patients over 18 years of age enduring a transient ischemic stroke or minor stroke within the past 3 months who had a minimum life expectancy of 1 year were included in this study. Same number, age-, and sex-matched individuals were included as controls. Patients were inquired on the presence of risk factors for stroke. A series of neuropsychological test batteries were administered in patient and control subjects for assessing cognitive functions. These tests were readministered at 6 and 12 months of follow-up to assess the progression of cognitive functions. Results: In this study among the patients with stroke, a significant impairment was seen in multiple cognitive functional tests following ischemic stroke as compared to control groups. The most common risk factors for stroke included hypertension (72.5%), hyperlipidemia, and cigarette smoking. The number of cognitive domains with an impairment was highest (in four cognitive tests) among those with coronary artery disease and atrial fibrillation, followed by those who had a >50% stenosis in Doppler (three cognitive tests). These findings suggest that the frequency of risk factors associated with stroke does not correlate with the frequency of risk factors associated with cognitive dysfunction. The stroke localizations were classified among the patients with stroke and reviewed in accordance with cognitive impairment. Conclusion: Neuropsychological tests, clinical findings, and imaging studies should be used to document the poststroke cognitive dysfunction.Publication Metadata only CORRELATION OF CAROTID ARTERY STENOSIS SEVERITY AND PERIOPERATIVE STENT COMPLICATIONS IN CAROTID ARTERY STENTING PATIENTS(2016-10-01T00:00:00Z) Deniz, C.; Guzel, V.; Halac, G.; Nasifov, M.; Goktekin, O.; Talip, A.; DENİZ, ÇİĞDEMPublication Metadata only Direct Catheter-Based Thrombectomy for Acute Ischemic Stroke Outcomes of Consecutive Patients Treated in Interventional Cardiology Centers in Close Cooperation With Neurologists(2015-07-28) WIDIMSKY, Petr; Asil, TALİP; ABELSON, Mark; KOZNAR, Boris; TASAL, Abdurrahman; ROOS, Johan; VASKO, Peter; PEISKER, Tomas; Deniz, Cigdem; VAVROVA, Jana; YAMAC, Hatice Aylin; STETKAROVA, Ivana; AY, Nuray Kahraman; Bacaksiz, AHMET; TUZGEN, Saffet; MALY, Marek; GOKTEKIN, Omer; ASİL, TALIP; DENİZ, ÇİĞDEM; BACAKSIZ, AHMET; KAHRAMAN AY, NURAYPublication Metadata only PROLONGED HYPOTENSION AFTER CAROTID ARTERY STENTING: INCIDENCE, PREDICTORS AND CONSEQUENCES(2016-10-01) GOKCAL, ELİF; NIFTALIYEV, E.; DENIZ, C.; ERGELEN, M.; GUZEL, VİLDAN; GOKTEKIN, O.; Asil, TALİP; GÖKÇAL, ELİF; DENİZ, ÇİĞDEM; GÜZEL, VİLDAN; ASİL, TALIPPublication Open Access Association between etiology and lesion site in ischemic brainstem infarcts: a retrospective observational study.(2018-03-13) BARAN, GÖZDE; GULTEKIN, TO; BARAN, O; DENIZ, C; KATAR, SELAHATTİN; Yildiz, GÜLSEN; ASIL, TALİP; BARAN, GÖZDE; DENİZ, ÇİĞDEM; KATAR, SELAHATTİN; BABACAN YILDIZ, GÜLSEN; ASİL, TALIPBackground and purpose: To assess the anatomical distribution of the ischemic strokes of the brainstem, the effect of anatomical distribution on clinical features and prognosis, and the association between etiology and anatomical involvement. Methods: A retrospective search of the patient database of our institution was performed for a total of 227 patients who were admitted to the Department of Neurology, Medical Faculty of Bezmialem Vakif University between January 2012 and September 2014. Patients with adequate diagnostic data and 3-month follow-up visit were included in the study. Results: Twenty-one (9%), 136 (60%), and 65 (29%) patients had an infarction only at the mesencephalon, pons, and medulla, respectively. However, a single patient (0.5%) had an infarction both at the mesencephalon and pons, 3 (1.5%) at the pons and medulla, and 1 (0.5%) at the mesencephalon, pons, and medulla. While anterior involvement was more common in the mesencephalon and pons, posterior and lateral involvement occurred more frequently in the medulla. Large arterial atherothrombosis was the predominant cause of the strokes in all anatomical sites, particularly in infarcts involving the pons. Cardioembolic events were more common in patients with mesencephalic infarcts. Also, ischemia due to dissection was more common in infarctions involving the medulla, especially the lateral medulla. In subjects with simultaneous infarcts at other sites in addition to the brainstem, there was a significantly higher co-occurrence of medullary infarcts with cerebellar infarcts, mesencephalic infarcts with posterior cerebral artery infarcts, and pons infarcts with anterior circulation and multiple infarcts. Conclusion: Determination of risk factors and infarct localization as well as prediction of etiological parameters may assist in improving survival rates and therapeutic approaches.Publication Open Access Multiple Spontaneous Intracranial-Extracranial Arterial Dissections in a Patient with Osteogenesis Imperfecta(2017-01-01T00:00:00Z) KOLUKISA, MEHMET; GÖKÇAL, ELİF; GÜRSOY, Azize Esra; DENİZ, ÇİĞDEM; ARALAŞMAK, Ayşe; ASİL, Talip; KOLUKISA, MEHMET; GÖKÇAL, ELİF; GÜRSOY, AZIZE ESRA; DENİZ, ÇİĞDEM; ARALAŞMAK, AYŞE; ASİL, TALIPA 40-year-old male with osteogenesis imperfecta (OI) was admitted to the hospital with an acute right monoparesis. Diffusion-weighted MRI showed infarction in the territory of the left anterior cerebral artery (ACA) and in the left posterior cerebral artery (PCA). In his vascular imaging, occlusion of the left vertebral artery (VA) starting from V2 segment was consistent with dissection and pseudoaneurysm in the right ACA. We presented this case because of the presence of spontaneous and simultaneous occurrence of both intracranial and extracranial arterial dissections in OI.Publication Open Access Atypical Clinical Course in a Patient with Acute Carotid Artery Dissection(2018-07-01T00:00:00Z) DENİZ, ÇİĞDEM; Ozdemir Gultekin, Tugce; Eryigit Baran, Gozde; ARALAŞMAK, Ayşe; Goktekin, Omer; ASİL, Talip; DENİZ, ÇİĞDEM; ARALAŞMAK, AYŞE; ASİL, TALIPExtracranial or intracranial artery dissections are more frequently reported because of cerebrovascular disease occurring in young adults. This condition is more likely to be associated with permanent morbidity and mortality. While anti-coagulant medications are commonly used for its treatment, an increased use of intravenous thromobolytic agents and endovascular treatments has also been reported. In this paper, the case of a patient with an atypical clinical course following thrombolytic treatment for acute extracranial internal carotid artery (ICA) dissection is presented in the context of a discussion regarding the safety and efficacy of aggressive treatment for extracranial arterial dissections.Publication Metadata only Epilepsy in Elderly Patients(2015-01-01T00:00:00Z) Halac, Gulistan; BİLGEN, HALİDE RENGİN; Kocaman, Gulsen; Niftaliyev, Elvin; DENİZ, ÇİĞDEM; ASİL, Talip; BİLGEN, HALİDE RENGİN; DENİZ, ÇİĞDEM; ASİL, TALIPObjectives: The incidence of new-onset epilepsy is high among the elderly. This study presents the demographic characteristics, etiological factors, seizure types and response rates to treatment in a group of patients aged 65 years or over with delayed-onset epilepsy.Publication Metadata only Association between cerebrovascular reactivity and severity of diabetic retinopathy in patients with diabetes mellitus(2015-04-01) YAMAN, A.; GULTEKIN, T.
