    Idiopathic intracranial hypertension: Are there predictors for visual outcome or recurrences?
    Tata, G; Kisabay, A; Gokcay, F; Celebisoy, N
    Objective: To find out the predictors of final visual outcome and recurrences in idiopathic intracranial hypertension (IIH). Patients and methods: Medical records of 75 patients with IIH were analyzed retrospectively. Gender, age of disease onset (AODO), body mass index (BMI), lumbar puncture opening pressure (LP-OP), visual acuity (VA) in logMAR, optical disc appearance (ODA), visual field (VF) mean deviation (MD), treatment results and recurrence rates were considered. Results: Mean age at onset age was 32.4 years, BMI was 311 kg/m(2) and median LP-OP was 380 mm H2O. All patients were treated with acetazolamide with a median dose of 1500 mg. The mean follow-up period was 44.8 months. AODO, BMI, LP-OP were not correlated with any of the examination parameters (VA, ODA, VF) at the first or last visit. The correlation between the VA and VF both at the first and last visit was not very powerful. VA of the last visit was fairly correlated with the VA of the first visit. However, the correlation between the last and first visit VF was very good. A very significant improvement in both VA and VF was recorded after treatment. Recurrences were noted in 23%. Demographic and clinical features of the recurring and non-recurring patients were not significantly different in terms of AODO, BMI, LP-OP, VA, VF or ODA. Conclusions: The patients with IIH respond to treatment with acetazolamide. First visit VF is the main determinant of the final visual outcome. Recurrences cannot be predicted by the demographic or clinical features at presentation.

    What is the optimal dose of acetazolamide in the treatment of idiopathic intracranial hypertension
    Ak, AK; Tata, G; Gokcay, F; Celebisoy, N
    Objective: Acetazolamide is preferred as the first-line drug for the medical treatment of idiopathic intracranial hypertension. In this study, the efficacy of different doses of the drug on visual functions; visual acuity, optic disc appearance- papilledema grade and visual field-mean deviation (VF-MD) were evaluated. Methods: The medical records of 73 patients diagnosed as idiopathic intracranial hypertension based on Modified Dandy Criteria and treated with acetazolamide who were on follow-up between 2010 and 2017 at the Neuro-ophthalmology Unit of Ege University Medical School, Department of Neurology were analyzed. Improvement in the visual functions at the end of the sixth month in three groups taking different doses of the drug; low (500, 750, 1000 mg/day), moderate (1500, 1750, 2000 mg/day) and high (3000, 4000 mg/day) were compared. Results: Improvement in visual acuity (p: 0.784), was not affected from different doses of the drug whereas papilledema grade (p: 0.014) and VF-MD (p<0.001) were affected. Binary comparisons revealed significant improvement in the high dose group when compared with the moderate and low dose groups both for the papilledema grade (low-high: p: 0.003, moderate-high: p: 0.024) and VF-MD (low-high: p<0.001, moderate-high: p: 0.001) Conclusion: Treatment with high doses of acetazolamide is associated with improvement in visual field defects and regression of optic disc edema in idiopathic intracranial hypertension.

    Risk for generalization in ocular onset myasthenia gravis: experience from a neuro-ophthalmology clinic
    Kisabay, A; ÖOzdemir, HN; Gökçay, F; Celebisoy, N
    Conversion to generalized myasthenia gravis (GMG) within the first 2 years has been reported in 18-85% of patients with ocular myasthenia gravis (OMG). The aim of the study was to investigate the risk factors for generalization in patients with OMG admitted to a neuro-ophthalmology clinic and to determine if there were differences between patients with GMG with predominant bulbar (GMG-B) or extremity muscle (GMG-E) involvement according to the 6th and 24th-month Myasthenia Gravis Foundation of America classification ranks. Patients with OMG who were followed-up for at least 24 months were retrospectively analyzed. Demographic, clinical, laboratory features and treatment strategies that can be associated with generalization and time to generalization were evaluated. Of the 139 patients with OMG, 54 (39%) showed generalization with a mean time of 10.3 (range 2-24) months. GMG-B and GMG-E were diagnosed in 31 (22.3%) and 23 patients (16.5%), respectively. Seropositivity for acetylcholine receptor and muscle-specific tyrosine kinase antibodies, abnormal single-fiber electromyography (SFEMG), and the presence of thymic abnormalities (thymoma and hyperplasia) were factors associated with generalization on multivariate analysis without a significant difference between the GMG-B and GMG-E groups. In addition, an abnormal repetitive nerve stimulation test was related to a shortened time to generalization. Bilateral ptosis at onset was found as a risk factor for generalization. In a neuro-ophthalmology clinic, bilateral ptosis as an initial feature of OMG must be approached cautiously because it may be the first sign of impending GMG.

    Cognıtıve functıons in idiopathic intracranial hypertensıon
    Ak, AK; Saritas, AS; Batum, M; Gemici, YI; Karakas, B; Celebisoy, N
    ObjectiveCognitive problems in idiopathic intracranial hypertension (IIH) is generally overlooked in the presence of disabling headache and threat to visual function. The aim of this study was to search for cognitive deficits in patients with IIH using neuropsychologic tests in addition to P300 potential recordings to assess cognition related brain activity.MethodsFifty IIH patients were examined using Montreal Cognitive Assessment Test, Stroop Test and Visual Aural Digit Span Test to measure different domains of cognition at the time of diagnosis. P300 potentials were recorded by using an oddball paradigm. Hospital Anxiety and Depression Scale was used to determine anxiety and depression. Quality of life (QoL) was assessed by SF-36. The results were compared with fifty healthy controls with matching age, gender and body mass index.ResultsNeuropsychologic tests revealed wide cognitive impairment including attention, working memory, executive function, naming, language, delayed recall and orientation in IIH patients. In addition, quality of life was affected in the sub-parameters of general health perceptions, emotional role functioning, vitality, mental health and bodily pain. P300 potential latencies were long and the amplitudes were reduced indicating deficits in attention and working memory. Anxiety scores were high, and health-related QoL was low mainly involving vitality, emotional and mental health. Cognitive dysfunction was not correlated with the levels of anxiety and the correlation with headache severity was mild.ConclusionA multidomain cognitive decline mainly involving attention and working memory was recorded in IIH patients. It was not correlated with anxiety and only a mild correlation with headache severity was present which may indicate a casual relationship between raised intracranial pressure and cognitive deficits. Screening is important as neuropsychological rehabilitation might be relevant in these patients.

    Background Migraine is a disease characterized by headache attacks. The disease is multifactorial in etiology and genetic and environmental factors play role in pathogenesis. Migraine can also be accompanied by psychiatric disorders like neurotism and obsessive compulsive disorder. Stress, hormonal changes and certain food intake can trigger attacks in migraine. Previous studies showed that eating attitudes and disorders are prevalant in patients with migraine. Eating disorders are psychiatric disorders related to abnormal eating habits. Both migraine and eating disorders are common in young women and personality profiles of these patient groups are also similar. A possible relationship which shows that migraine and eating habits are related can lead to a better understanding of disease pathogenesis and subsequently new therapeutic options on both entities. Association of migraine in relation to severity, depression and anxiety and eating habits and disorders were aimed to be investigated in this study.Methods The study was designed as a prospective, multi-center, case control study. Twenty-one centers from Turkey was involved in the study. The gathered data was collected and evaluated at a single designated center. From a pool of 1200 migraine patients and 958 healthy control group, two groups as patient group and study group was created with PS matching method in relation to age, body-mass index, marital status and employment status. Eating Attitudes Test-26 (EAT-26), Beck's Depression Inventory (BDI) and Beck's Anxiety Inventory (BAI) were applied to both study groups. The data gathered was compared between two groups.Results EAT-26 scores and the requirement for referral to a psychiatrist due to symptoms related to eating disorder were both statistically significantly higher in patient group compared to control group (p = 0.034 and p = 0.0001 respectively). Patients with migraine had higher scores in both BDI and BAI compared to control group (p = 0.0001 and p = 0.0001 respectively). Severity of pain or frequency of attacks were not found to be related to eating attitudes (r:0.09, p = 0.055).Conclusions Migraine patients were found to have higher EAT-26, BDI and BAI scores along with a higher rate of referral to a psychiatrist due to symptoms. Results of the study showed that eating habits are altered in migraine patients with higher risk of eating disorders. Depression and anxiety are also found to be common amongst migraine patients.
