Item Quality of Life in Patients with Idiopathic Intracranial Hypertension and the Impact of the COVID-19 PandemicÇelebisoy, N; Ak, AK; Özdemir, HN; Gökçay, F; Eser, EThe COVID-19 pandemic became a challenge to maintain care for patients with idiopathic intracranial hypertension (IIH). We aimed to find out how they were affected during lockdown. Thirty IIH patients admitted to hospital during the COVID-19 pandemic were studied. Their demographic and neuro-ophthalmological findings were evaluated. The World Health Organization - Five Well-Being Index (WHO-5), the EUROHIS Quality of Life (QOL) 8-item index, National Eye Institute Visual Functioning Questionnaire (NEI-VFQ-25), Headache Impact Test (HIT-6), and COVID-19 Fear Scale were used to assess QOL and pandemic-associated fear. Thirty age, sex, and body mass index matched volunteers constituted the control group. Apart from the COVID-19 Fear Scale and colour vision subscale of the NEI-VFQ-25, all scale scores were worse in IIH patients than in healthy control subjects. Patients with severe visual field defects had higher HIT-6 scores (p = .036). Both vision-specific and overall QOL was reduced in patients with IIH. Headache severity and disability were more prominent in patients with severe visual loss. Fear caused by the COVID pandemic was not different in IIH patients than in healthy control subjects.Item c, Ceyla Atac d, e, Nes , e C,elebisoy eAk, AK; Çinar, C; Dogan, GN; Ataç, C; Gökçay, F; Çelebisoy, NPatients with indirect carotid cavernous fistulas (CCF) were reviewed to emphasize the importance of diagnosing patients even with trivial findings and to raise awareness. Eighteen patients diagnosed as CCF were included. Neuro-ophthalmological findings before and after treatment, diagnostic investigations, treatment, clinical course was noted. Twelve patients were female (67%), 6 were males (33%) and the mean age at presentation was 54 years (range: 29-70 years). Conjunctival hyperemia was present in all patients. Seventeen (94%) patients had proptosis and diplopia, nine (50%) had orbital pain and/or headache, four (22%) had blurred vision, one (5.5%) had ptosis. On examination, 17 patients (94%) had restricted eye movements, four (22%) had low visual acuity and five patients had (28%) increased intraocular pressure (IOP). One patient had been diagnosed as myasthenia gravis and two as thyroid orbitopathy and had been on treatment accordingly before CCF was diagnosed. In two patients, bilateral findings were present despite unilateral CCF on angiography. Barrow Type B fistula was found in 7 (38%), Barrow Type D in 11 (62%) patients. In three bilateral CCF was detected. All were treated by endovascular intervention. Residual deficits at the sixth month control were, eye movement deficits in seven (39%), decrease in visual acuity in one (5.5%) and elevated IOP in one (5.5%) patient. Indirect CCF patients generally present with mild symptoms and the diagnosis may be overlooked. Mild progressive ophthalmoparesis with conjunctival hyperemia must be warning. Though rare bilateral CCF can be detected as well as unilateral CCF with bilateral findings.Item Tremor, gait, and balance disorders in essential tremor and the efficacy of atenololKisabay, AKA; Durmaz, GS; Ataç, C; Duksal, T; Gökçay, F; Çelebisoy, NBackground: To assess gait and balance in patients with essential tremor (ET), which is the most common tremor disorder characterized by bilateral action tremor of the hands with possible involvement of further tremor locations and to test the efficacy of atenolol on tremor and gait and balance. Methods: In this prospective study, gait and balance were evaluated by static posturography in addition to International Cooperative Ataxia Rating Scale (ICARS) in 22 ET patients without any additional neurologic signs on examination. Tremor severity was assessed by The Essential Tremor Rating Assessment Scale (TETRAS). The efficacy of atenolol 100 mg/day both on tremor and gait and balance was investigated. Posturographic recordings were performed in gender, age-, and height-matched healthy volunteers who constituted the control group. Results: The mean center of gravity sway velocity of the ET patients recorded on firm and foam surfaces with eyes open and closed was not significantly different from the healthy controls but sway velocity on tandem stance was significantly increased (P = 0.032). Gait speed (P = 0.015) was decreased and step width was increased (P = 0.001). An improvement in TETRAS scores was recorded with atenolol treatment (P = 0.046). An improvement not reaching statistical significance was present in ICARS scores (P = 0.059). However, posturographic parameters did not change significantly (P > 0.05). Conclusion: Increased sway velocity on tandem stance, decreased gait speed and increased step width are consistent with midline cerebellar dysfunction in ET patients with no obvious gait and balance deficits on clinical examination. Atenolol seems to be effective on tremor but does not cause a significant improvement in gait and balance deficits.Item Risk for generalization in ocular onset myasthenia gravis: experience from a neuro-ophthalmology clinicKisabay, A; ÖOzdemir, HN; Gökçay, F; Celebisoy, NConversion 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.Item Calcitonin gene-related peptide (CGRP) levels in peripheral blood in patients with idiopathic intracranial hypertension and migraineAk, AK; Gemici, YI; Batum, M; Karakas, B; Özmen, EY; Gökçay, F; Çelebisoy, NBackground: Calcitonin gene-related peptide (CGRP) plays a dominant role in migraine. This prospective study was designed to investigate CGRP levels in patients with idiopathic intracranial hypertension (IIH) and compare the results of migraine patients and healthy controls (HC). As a second objective, CGRP levels obtained from IIH patients defining sustained headache after the resolution of papilledema were compared with those not defining post-IIH headache. Methods: Thirty-six patients with IIH, 36 with episodic migraine (EM), 18 with chronic migraine (CM), and 36 HC were included in the study. CGRP levels were studied from blood samples obtained from the antecubital vein by using a commercial ELISA kit. Results: Serum CGRP levels of the patient groups were significantly higher than the HC (p < 0.001). As compared with controls, both CM (p Adj<0.001) and IIH (p Adj=0.039) had significantly increased levels of CGRP. Levels recorded from EM patients did not differ from the HC (p Adj=0.661). In 16 IIH patients, persistent headache was reported after the normalization of intracranial pressure (ICP). Twenty patients did not report post-IIH headaches. Comparison of serum CGRP levels of these two groups revealed significantly higher CGRP levels in patients with sustained headaches obtained from blood samples both at the initial and control visit (p Adj <0.001). Conclusions: CGRP levels of the patient groups were higher than the HC. High levels recorded in patients with IIH indicates the role of CGRP in IIH related headache and even higher levels in patients with sustained headache after normalization of ICP strengthens this finding.Item Airplane headache: An atypical case with autonomic symptoms and long durationAtaç, C; Ak, AK; Çetin, G; Batum, M; Gökçay, F; Selçuki, DAirplane Headache (AH) which is classified under headache attributed to disorder of homeostasis in International Classification of Headache Disorders (ICHD)-3 is a severe, unilateral, orbitofrontal headache that occurs during and caused by airplane travel. It remits after landing. AH cases with autonomic symptoms had rarely been reported. We present a 35-year-old male complained of five attacks of right-sided, unilateral, orbitofrontal headache accompanied with lacrimation, conjunctival injection and eye redness ipsilaterally, starting 20-30 minutes prior to landing. The headache duration varied between 30-90 minutes. AH diagnosis was made in the light of anamnesis and neurological examination. The secondary causes and primary headaches with autonomic symptoms were ruled out. As far as we know this is the first reported longer duration AH case with autonomic symptoms in the literature. AH is an underdiagnosed headache. We report this atypical AH case to call attention to this rare but treatable headache.Item Vestibular migraine and persistent postural perceptual dizziness: Handicap, emotional comorbidities, quality of life and personality traitsAk, AK; Çelebisoy, N; Özdemir, HN; Gökçay, FObjective: To compare vestibular migraine (VM) and persistent postural-perceptual dizziness (PPPD) regarding dizziness associated handicap, emotional and somatic disorders, health-related quality of life (QoL) and per-sonality traits.Methods: Thirty patients for each group [VM, PPPD and healthy volunteers (HC)] were studied. Dizziness Handicap Inventory (DHI), Beck depression and anxiety scales, Somatic Symptom Scale-8 (SSS-8), Short Form (36) Health Survey (SF 36) and the Big Five Inventory (BFI) were used.Results: DHI sub-scores were significantly high in both patient groups in comparison with the HC (p < 0.001 for all). Emotional (p = 0.001) and functional (p = 0.022) sub-scores of the PPPD patients were worse. Anxiety and somatic symptom scores of VM (p = 0.026 and p < 0.001 respectively) and PPPD (p < 0.001 for both) and depression scores of the PPPD (p = 0.003) were higher than the HC. Both anxiety (p = 0.009) and somatization (p = 0.005) scores of the PPPD patients were higher than the VM. SF-36subscales were affected in both groups (p < 0.05). Vitality (p = 0.002), mental health (p = 0.045) and social role functioning (p = 0.006) of the PPPD group were worse than the VM. Higher scores for neuroticism (p < 0.001) was present for both groups. Scores for extraversion was low in PPPD patients (p = 0.010) in comparison with the HC.Conclusion: Dizziness associated handicap, anxiety and somatic symptom burden is high in both groups, even higher in PPPD with additional depression. Severe impairment in QoL is present with more severe impairment in emotional aspects in patients with PPPD. Neuroticism is a common personality trait for both groups with additional introversion in PPPD.Item Factors determining the response to treatment in patients with vestibular migraineAk, A; Çelebisoy, N; Saruhan, G; Gökçay, F; Karti, DT; Toydemir, H; Yayla, V; Isikay, AC; Erkent, I; Özçelik, P; Akdal, G; Ataç, C; Bicakci, S; Goksu, EO; Gulec, FItem Vestibular migraine, demographic and clinical features of 415 patients: a multicenter studyAk, A; Çelebisoy, N; Özdemir, H; Gökçay, F; Saruhan, G; Karti, DT; Toydemir, H; Yayla, V; Isikay, AC; Erkent, I; Özçelik, P; Akdal, G; Ataç, C; Bicakci, S; Goksu, EO; Gulec, FItem Trigeminal neuralgia following Tolosa-Hunt syndromeDurmaz, GS; Ak, AK; Gökçay, F; Çelebisoy, NItem Risk for generalization in ocular onset myasthenia gravis: experience from a neuro-ophthalmology clinicCelebisoy, N; Ak, A; Özdemir, H; Gökçay, FItem The impact of Covid-19 pandemic on idiopathic intracranial hypertension patientsÇelebisoy, N; Ak, A; Özdemir, H; Gökçay, F; Eser, EItem Comparison of clinical features in patients with vestibular migraine and migraineÇelebisoy, N; Ak, AK; Ataç, C; Özdemir, HN; Gökçay, F; Durmaz, GS; Karti, DT; Toydemir, HE; Yayla, V; Isikay, IÇ; Erkent, I; Saritas, AS; Özçelik, P; Akdal, G; Biçakci, S; Göksu, EO; Uyaroglu, FGVestibular migraine (VM) is accepted as the most common cause of spontaneous episodic vertigo. In most patients, vestibular symptoms follow migraine headaches that begin earlier in life. The aim of this multicenter retrospective study was to find out the differences between migraine patients without any vestibular symptoms (MwoV) and VM patients and to delineate the specific clinical features associated with VM. MwoV and VM patients were compared regarding demographic features, migraine headache years, headache attack frequency, intensity, symptoms associated with headache and vertigo attacks, presence of menopause, history of motion sickness and family history of migraine. Four-hundred and forty patients with MwoV and 408 patients with VM were included in the study. Migraine with aura was more frequent in patients with MwoV (p = 0.035). Migraine headache years was longer (p < 0.001) and headache intensity was higher in patients with VM (p = 0.020). Aural fullness/tinnitus was more common in patients with VM (p < 0.001) when all other associated symptoms were more frequent in patients with MwoV (p < 0.001) as well as attack triggers (p < 0.05). Presence of menopause and motion sickness history was reported more frequently by VM patients (p < 0.001). Logistic regression analysis indicated that longstanding history of migraine with severe headache attacks, aural fullness/tinnitus accompanying attacks, presence of menopause, previous motion sickness history were the differentiating clinical features of patients with VM.Item Vestibular migraine, demographic and clinical features of 415 patients: A multicenter studyÇelebisoy, N; Ak, AK; Özdemir, HN; Gökçay, F; Durmaz, GS; Karti, DT; Toydemir, HE; Yayla, V; Isikay, AIC; Erkent, I; Ozcelik, P; Akdal, G; Ataç, C; Biçakci, S; Göksu, EO; Uyaroglu, FGObjective: To evaluate demographic and clinical features of vestibular migraine (VM) patients Methods: Four hundred fifteen patients with VM were evaluated by using a structured questionnaire in addition to clinical examination. Results: The mean age of headache and vertigo onset was 25 years and 39 years, respectively. In 12.3%, benign paroxysmal positional vertigo (BPPV) was detected during the interictal period. Ten percent had hearing loss on audiometry, in 8.7% it was one-sided low-frequency sensory-neural hearing loss below 2000 Hz and the history was typical for Meniere's disease (MD) in addition to VM. Tinnitus was present in 94.4%, aural fullness in 83.4%, nausea in 72.2% and vomiting in 30.5% of patients with VM/MD. The prevalence of these symptoms was higher in patients with VM/MD than in pure VM. Median attack severity determined by visual analog scale measured in centimeters from 0 to 10 was 8 for headache and 7 for vertigo for the whole group. Severe headache was significantly correlated with age of < 43 years (OR: 6.831, 95% CI: [4.10-11.63]; p < 0.001) and severe vertigo was significantly correlated with age > 41 years (OR: 7.073, 95% CI: [4.55-10.98]; p < 0.001). Motion sickness was revealed from past medical history in 51.8%. Family history of migraine was present in 72.5% and the age of onset of both migraine headaches (p = 0.008) and vertigo attacks (p = 0.004) was lower in these patients. Conclusion: Younger patients suffered more severe headache attacks whereas vertigo attack severity was higher in the elderly. BPPV and MD were commonly associated with VM and VM/MD was accompanied by aural and autonomic features more frequently than pure VM. Previous history of motion sickness was detected in more than half of the whole group. Family history of migraine was associated with younger onset of migraine headaches and vertigo attacks.Item Factors determining the response to treatment in patients with vestibular migraineAk, AK; Çelebisoy, N; Özdemir, HN; Gökçay, F; Durmaz, GS; Karti, DT; Toydemir, HE; Yayla, V; Isikay, AIÇ; Erkent, I; Özçelik, P; Akdal, G; Ataç, C; Biçakci, S; Ozaydin-Göksu, E; Uyaroglu, FGPurpose To find out clinical features associated with poor response to treatment in vestibular migraine (VM) Methods VM patients treated with drugs recommended in migraine prophylaxis were included in this multicenter study. Migraine features including type, age of onset of headache and vertigo attacks, attack frequency, intensity, associated symptoms, triggering factors, presence of interictal dizziness/imbalance, anxiety, depression, history of motion sickness, and family history of migraine were noted. Amitriptyline, flunarizine, propranolol, topiramate and venlafaxine were chosen depending on patients' individual requirements. Maximum dose of each drug was tried for 2 months to decide its efficacy. In the case of inefficacy, it was changed with another preventive drug of different class. If there was still no improvement, two drugs of different classes were combined. >= 50% reduction in attack frequency and severity in patients using one drug and a combination of two drugs was compared, with patients showing <50% reduction despite combination therapy, regarding their clinical features. Results The results of 430 VM patients, 65 men and 365 women with a mean age of 42.2 +/- 12.2 years (range: 17-74 years), were analyzed. Conclusion Cutaneous allodynia frequently associated with female sex, comorbid anxiety and depression and interictal dizziness/imbalance enhanced with comorbid anxiety were risk factors for reduced treatment response. Aural fullness might be the clue of impending concomitant Meniere's disease not responding to migraine preventives.Item Prognostic predictors of remission in ocular myasthenia gravisÇelebisoy, N; Orujov, A; Balayeva, F; Özdemir, HN; Ak, AK; Gökçay, FBackground Ocular myasthenia gravis (OMG) constitutes 15% of all myasthenia gravis patients. MethodsOne hundred eight patients with OMG followed-up for over 36 months were retrospectively evaluated regarding factors associated with remission. Demographic features, neuro-ophthalmologic findings at onset, acetylcholine receptor (AChR Ab) and muscle-specifc tyrosine kinase antibodies (MuSK Ab), thymic status, single fiber electromyography (SFEMG) results were the variables considered. ResultsMedian age of disease onset was 57 years (range 18-82 years). Clinical features at onset was isolated ptosis in 55 (50.9%) and isolated diplopia in 33 (30.6%) patients. Combined ptosis and diplopia were present in 20 (18.5%) patients. Among 75 patients with ptosis, it was unilateral in 65 (86.7%) and bilateral in 10 (13.3%). AChR Abs were found in 66 (61.1%) and MuSK Abs in 2 (1.9%) patients. SFEMG abnormality was detected in 74 (68.5%) patients. Thymoma was present in 16 (14.8%) and thymic hyperplasia in 6 (5.6%) patients. Forty-one patients (37.9%) had been treated with pyridostigmine alone. Sixty-seven (62%) patients were given immunosupressive drugs. In 53 (49.1%) prednisone was used and in 14 (12.9%) patients it was combined with azathioprine. Thymectomy was performed in all 16 patients with thymoma. Complete stable remission (CSR) was achieved in 49 (45.4%) patients. Fifty-nine (54.6%) patients had reached minimal manifestation (MM) status; 32 (29.6%) having a status of MM-1 and 27 (25%) a status of MM-3. ConclusionsThe presence of AchR Abs (p = 0.034) and an abnormal SFEMG (p = 0.006) at onset as increased risk factors for the presence of ongoing signs necessitating medical treatment.
