Methods: Patients with GBS were prospectively recruited between April 2019 and March 2022 and two electrodiagnostic examinations were performed on each patient. The criteria of Ho et al.

The effect of sleep disorders on quality of life in patients with epilepsy: A multicenter study from Turkey.

Objective: We aimed to investigate sleep disorders in patients with epilepsy (PWE) and to investigate the effects of sleep disorders on quality of life.

Methods: In our multicenter study conducted in Turkey, 1358 PWE were evaluated. The demographic and clinical data of the patients were recorded.

Birth outcomes in pregnant women with epilepsy: A Nationwide multicenter study from Türkiye.

Objective: The present study was aimed at investigating the effects of anti-seizure medications (ASMs), patient demographic characteristics, and the seizure type and frequency on the development of congenital malformations (CMs) in the infants of pregnant women with epilepsy (PWWE).

Methods: PWWE followed up at the neurology outpatient clinic of 21 centers between 2014 and 2019 were included in this prospective study. The follow-up of PWWE was conducted using structured, general pregnant follow-up forms prepared by the Pregnancy and Epilepsy Study Committee.

Eye closure sensitivity and genetic generalized epilepsies: A prospective study of 123 cases.

Purpose: To investigate the possible relationship between eye closure sensitivity (ECS) and genetic generalized epilepsy (GGE) in terms of epilepsy syndromes, photosensitivity (PS), and prognosis.

Method: One hundred and twenty-three patients diagnosed with GGE were classified according to epilepsy syndromes. Among them, ECS and PS were detected in repeated video-EEGs.

Panayiotopoulos Syndrome with a special emphasis of ictal semiologic features.

Purpose: The aim was to identify the demographic, electroencephalographic findings, clinical features, especially ictal semiological symptoms of patients diagnosed with Panayiotopoulos Syndrome.

Method: The semiologic and EEG findings of 42 patients were reviewed. Statistical analysis was used to determine the frequencies of semiologic features and to define the symptom clusters.

Acquired hepatocerebral degeneration.

Acquired hepatocerebral degeneration is a rare, mostly irreversible neurological syndrome that occurs in patients with chronic liver disease, particularly in those with surgically or spontaneously induced portosystemic shunts. Typical magnetic resonance findings are T1 hyperintensity in the pallidum, substantia nigra, periaquaductal gray matter. In this paper, we report a case of a 51-year-old woman presented with hepatic encephalopathy episodes and typical magnetic resonance findings, who does not develop any neurological signs or symptoms, nor cognitive decline in the follow up period, lasting for 3 years.

The Prevalence of Headache in Crohn's Disease: Single-Center Experience.

Objectives. This study is aimed at studying the prevalence and characteristics of different types of headaches in patients with Crohn's disease. Materials and Methods.

Myoclonus-dystonia syndrome: case report.

Myoclonus-dystonia syndrome (MDS) is a rare disease manifesting myoclonus as the only neurological symptom which may be accompanied by dystonia. It usually starts in the first or second decade of life. It has a benign course with spontaneous remissions but can cause functional disability in some patients.

Genome-wide association analysis of genetic generalized epilepsies implicates susceptibility loci at 1q43, 2p16.1, 2q22.3 and 17q21.32.

Genetic generalized epilepsies (GGEs) have a lifetime prevalence of 0.3% and account for 20-30% of all epilepsies. Despite their high heritability of 80%, the genetic factors predisposing to GGEs remain elusive.

An association analysis at 2q36 reveals a new candidate susceptibility gene for juvenile absence epilepsy and/or absence seizures associated with generalized tonic-clonic seizures.

Purpose: To further evaluate the previously shown linkage of absence epilepsy (AE) to 2q36, both in human and WAG/Rij absence rat models, a 160-kb region at 2q36 containing eight genes with expressions in the brain was targeted in a case-control association study involving 205 Turkish patients with AE and 219 controls.

Methods: Haplotype block and case-control association analysis was carried out using HAPLOVIEW 4.0 and inhibin alpha subunit (INHA) gene analysis by DNA sequencing.

Right cerebral hemiatrophy: neurocognitive and electroclinical features.

The purpose of this study was to retrospectively evaluate the cognitive and electroclinical characteristics of right cerebral hemiatrophy (Dyke-Davidoff-Masson syndrome [DDMS]). Cognitive assessments with a particular emphasis on visuospatial functions, electroclinical features, and neuroimaging characteristics were analyzed for five patients with a clinically and neuroradiologically confirmed diagnosis of right-sided DDMS. Intelligence tests revealed mental retardation in all but one.

Panayiotopoulos syndrome with coincidental brain lesions.

Purpose: To describe the clinical and electroencephalographic features of three patients diagnosed with Panayiotopoulos syndrome with different lesions identified by cranial MRI investigation.

Methods: Our study was based on patients from the Epilepsy Outpatient Clinic of Sişli Etfal Education Hospital in Istanbul, where a prospective study of Panayiotopoulos syndrome was initiated in 1995. Records of our Epilepsy Outpatient Clinic revealed 53 patients with Panayiotopoulos syndrome.

Triphasic EEG pattern in bilateral paramedian thalamic infarction.

Two cases of bilateral paramedian thalamic infarction (BPTI) showing triphasic waves (TWs) on the electroencephalogram (EEG) at acute stage are presented in this study. BPTI is a rare syndrome with decreased level of consciousness, gaze abnormalities and cognitive deterioration. TWs are nonspecific EEG findings occurring in both metabolic and nonmetabolic conditions.

Overlap cases of eyelid myoclonia with absences and juvenile myoclonic epilepsy.

Eyelid myoclonia with absences (EMA) and juvenile myoclonic epilepsy (JME) are two separate epileptic syndromes included in the new classification of epilepsies and epileptic syndromes by ILAE in 2001. Both are idiopathic generalized epilepsies with their clinical onset in the first two decades. EMA is characterized by eyelid myoclonia associated with absences and photosensitivity.

Hot water epilepsy: clinical and electroencephalographic features of 25 cases.

The aim of this study was to analyze the clinical and electroencephalographic findings for 25 patients with hot water epilepsy. Personal and family history, neurological state, age at onset and types of seizures, provoking factors, bathing habits, EEGs, and neuroimages were all reviewed. Age at onset of seizures ranged from 6 months to 37 years.

Hot water epilepsy with cerebral lesion: a report of five cases with cranial MRI findings.

Hot water epilepsy (HWE) is included in the reflex epilepsies. Although, in general, not common, HWE is concentrated in certain regions of the world. Different bathing habits and genetic factors may be responsible for the high incidence of HWE in these regions.

Tonic seizures in subacute sclerosing panencephalitis: a video-illustration of two cases.

Subacute sclerosing panencephalitis is a progressive disorder which also presents with various types of seizures, mainly myoclonic jerks, atonic attacks and tonic-clonic seizures. We report two cases, documented by video-EEG that during the course of the disease also presented with tonic seizures. The differential diagnosis of non-epileptic paroxysmal events might prove to be a problem.

Evidence against association between arachnoid cysts and epilepsy.

Arachnoid cysts are often discovered incidentally in MRs performed for a variety of reasons. In this study, we have attempted to determine a possible relationship between the arachnoid cyst, seizure type and EEG abnormalities. Eight patients were classified according to the Classification of Epilepsies and Epileptic Syndromes of ILAE as idiopathic generalized or localized epilepsy: three as idiopathic generalized epilepsy, three as Rolandic epilepsy and two as juvenile myoclonic epilepsy.
