Eating attitudes of migraine patients in Turkey: a prospective multi-center study.

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.

Are COVID-19 vaccines safe for people with epilepsy? A cross-sectional study.

BACKGROUND: COVID-19 disease was first seen in December 2019 and was declared a pandemic soon after. To fight the pandemic, there is an immense need for effective vaccines. The purposes of our study were to investigate the effect of coronavirus vaccines on seizures in people with epilepsy (PWE) and assess the adverse events of COVID-19 vaccine in PWE. METHODS: This was a cross-sectional study. We included epilepsy patients who got vaccinated with two or three doses at least 1 month earlier. We gathered the data using a standardized form. The form contained questions about patients' demographic features, clinical features, and information about the vaccination and its adverse events. The questionnaire included questions about epilepsy-related adverse events. RESULTS: We included 178 people with epilepsy in our study. The frequency of adverse events was lower than clinical studies of the vaccines. The mean number of seizures in the month before the vaccination was 1.62, between the doses was 1.61, and after vaccination was 1.64. There was no significant difference in the number of monthly seizures before the vaccination, the month between the doses, or the month after the vaccination (p = 0.46). CONCLUSIONS: The vaccines under consideration in our study were tolerated well by the epilepsy patients. The vaccines did not affect the monthly number of seizures of the PWE. A small number of patients had more seizures than normal after vaccination. We think that benefits of the vaccines outweigh the slightly increased possibility of having a seizure after vaccination.

The evaluation of patient demographics, etiologies and apraclonidine test results in adult Horner's syndrome.

PURPOSE: We aimed to demonstrate the patient demographics, etiologies and apraclonidine test results in adult Horner's syndrome. METHODS: This retrospective study was performed by the analysis of medical data of patients who were given 0.5% apraclonidine test. Patients' past medical history, demographic data, etiologies, accompanying neurological findings and pharmacological test results were assessed. RESULTS: Forty patients (21 females and 19 males) with a mean age of 50.3 ± 11.6 years were evaluated. Apraclonidine 0.5% test was positive in 37 patients (92.5%). An etiology could be identified in 20 patients (central [9 patients, 45%], preganglionic [9 patients, 45%] and postganglionic [2 patients, 10%]). Neurological findings accompanying Horner's syndrome were present in 8 patients. CONCLUSION: Despite detailed investigations, in a significant number of patients with Horner's syndrome an underlying cause may not be detected. Among the identifiable lesions, central and preganglionic involvements are still the first leading causes of Horner's syndrome. In addition, apraclonidine test may not be positive in all patients and a negative response does not exclude Horner's syndrome.

Quality of Life in Patients with Idiopathic Intracranial Hypertension and the Impact of the COVID-19 Pandemic.

The 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.

Recognition and clinical implications of high prevalence of migraine in patients with Brugada syndrome and drug-induced type 1 Brugada pattern.

INTRODUCTION: We have previously reported high 1-year prevalence of migraine in patients with atrial arrhythmias associated with DI-type 1 BrP. The present study was designed to determine the lifetime prevalence of migraine in patients with Brugada syndrome (BrS) or drug-induced type 1 Brugada pattern (DI-type 1 BrP) and control group, to investigate the demographic and clinical characteristics, and to identify clinical variables to predict underlying BrS/DI-type 1 BrP among migraineurs. METHODS AND RESULTS: Lifetime prevalence of migraine and migraine characteristics were compared between probands with BrS/DI-type 1 BrP (n = 257) and control group (n = 370). Lifetime prevalence of migraine was 60.7% in patients with BrS/DI-type 1 BrP and 30.3% in control group (p = 3.6 × 10-14 ). On stepwise regression analysis, familial migraine (odds ratio [OR] of 4.4; 95% confidence interval [CI]: 2.0-9.8; p = 1.3 × 10-4 ), vestibular migraine (OR of 5.4; 95% CI: 1.4-21.0); p = .013), migraine with visual aura (OR of 1.8; 95% CI: 1.0-3.4); p = .04) and younger age-at-onset of migraine (OR of 0.95; 95% CI: 0.93-0.98); p = .004) were predictors of underlying BrS/DI-type 1 BrP among migraineurs. Use of anti-migraine drugs classified as "to be avoided" or "preferably avoided" in patients with BrS and several other anti-migraine drugs with potential cardiac INa /ICa channel blocking properties was present in 25.6% and 26.9% of migraineurs with BrS/DI-type 1 BrP, respectively. CONCLUSION: Migraine comorbidity is common in patients with BrS/DI-type 1 BrP. We identify several clinical variables that point to an underlying type-1 BrP among migraineurs, necessitating cautious use of certain anti-migraine drugs.

What is the role of diffusion tensor imaging (DTI) in detecting subclinical pyramidal tract dysfunction in Behçet's and neuro-Behçet's cases?

The aim of this study is to investigate the pyramidal tract integrity with DTI in Behçet's and neuro-Behçet's cases. We performed this technique in two subgroups of neuro-Behçet's patients (parenchymal and vascular), and Behçet's cases without neurological involvement and control group. Totally, 28 patients were investigated. The control group was composed of 14 healthy people. Cranial MR and DTI were performed in three patient groups and the control group. At DTI, circular regions of interest (ROI) were symmetrically drawn on axial slices on the left and right sides along the pyramidal tract pathway at two levels: middle one third of the cerebral peduncle and posterior limb of the internal capsule. Fractional anisotropy (FA) values for each ROI were obtained by averaging all voxels within the ROI. Calculated FA values on both sides (left and right) of the posterior limb of the internal capsule and cerebral peduncle are significantly lower in all three patient groups when compared to the control group. But there is no any difference of FA values in the selected brain regions of three patient groups. FA values on the posterior limb of the internal capsule and cerebral peduncle do not show a statistically significant difference in parenchymal neuro-Behçet's cases. Our study demonstrates that DTI can detect subclinical pyramidal tract dysfunction in neuro-Behçet's and Behçet's patients. Detection of subclinical nervous system involvement is crucial for morbidity in Behçet's disease. For this reason, studies based on DTI, which include a large number of patients and explore different brain regions, are needed to guide clinicians.

Acute effect of caffeine on pattern-reversal visual evoked potential: a randomized-controlled study.

Purpose: This study was aimed to investigate the acute effect of caffeine intake on pattern-reversal (PR) visual evoked potential (VEP). Methods: This randomized controlled study included 40 participants who were divided into two groups randomly (group 1 [study group, n = 20] and group 2 [control group, n = 20]). While the study group received coffee beverages made from 6 g pure coffee beans (36 mg of caffeine per gram) containing approximately 216 mg caffeine, the control group was given beverages containing 200 mg lactose without caffeine. PR-VEP test was performed at baseline and 1 h after the beverage intake. The right eyes of both groups were used for the statistical analysis. Results: The median age of group 1 (8 male and 12 female) and group 2 (7 male and 13 female) were 31.0 (range, 21-59) and 36.5 (range, 20-59) years, respectively. No statistically significant difference was found between two groups in terms of age (p = 0.398) and gender (p = 0.744). Before the caffeine intake, median P100 latency and amplitudes were 109.90 ms (range: 99.60-120.60) and 12.45 µV (range: 5.20-19.30), respectively. One hour after caffeine intake, corresponding values were 110.70 ms (range: 99.00-114.60) and 12.45 µV (range: 5.70-20.0). Baseline P100 latency and amplitude values were not significantly different from the values recorded 1 h after caffeine intake (p > 0.05). Conclusions: This study showed that ingesting moderate amounts of caffeine did not affect PR-VEP parameters. Therefore, caffeine restriction does not seem to be required before the PR-VEP test. Further studies are needed to confirm our findings.

Baseline demographics, clinical features, and treatment protocols of 240 patients with optic neuropathy: experiences from a neuro-ophthalmological clinic in the Aegean region of Turkey.

PURPOSE: To analyze the demographic patterns, clinical characteristics, and treatment protocols of optic neuropathies. MATERIALS AND METHODS: The hospital data of patients with optic neuropathy admitted to the Department of Neuro-ophthalmology in a tertiary referral center in Turkey between January 2010 to January 2017 were retrospectively analyzed. Demographic patterns, clinical features, treatment protocols, and the natural disease courses were assessed. RESULTS: The total number of patients with optic neuropathy seen over this period was 240, which consist of 43 with idiopathic optic neuritis (17.9%), 40 with multiple sclerosis-related optic neuritis (16.7%), 12 with chronic relapsing inflammatory optic neuritis (5.0%), 12 with atypical optic neuritis (5.0%), 11 with neuromyelitis optica spectrum disorders-related optic neuritis (4.6%), 90 with non-arteritic ischemic optic neuropathy (37.5%), 4 with arteritic ischemic optic neuropathy (1.7%), 10 with traumatic optic neuropathy (4.1%), 6 with compressive optic neuropathy (2.5%), and 12 with mitochondrial optic neuropathy [9 with toxic optic neuropathy (3.7%) and 3 with Leber's hereditary optic neuropathy (1.2%)]. There were 101 males (42%) and 139 females (58%). The mean age was 43.34 ± 15.86 years. CONCLUSION: This study reported the demographics, clinical characteristics, and treatment protocols of optic neuropathies in a neuro-ophthalmology specialty clinic at a tertiary referral center in Turkey during the past decade. The data may be useful in assessing the global status of optic neuropathies.

Cervical vestibular-evoked myogenic potentials in patients with multiple sclerosis: sensitive in detecting brainstem involvement?

Cervical vestibular-evoked myogenic potentials (cVEMPs) are accepted to demonstrate the vestibulo-collic reflex. However, the brainstem pathway is still not fully understood. The aim of the study was to evaluate the contribution of cVEMPs to detection of brainstem involvement in multiple sclerosis (MS). Thirty patients fulfilling the criteria for definite MS were included in the study. All were newly diagnosed cases, admitted due to an attack with active lesions on MRI. Thirty-one age- and sex-matched healthy controls constituted the control group. The latencies of peaks p13 and n23 and peak-to-peak amplitude of p13-n23 were measured. Brainstem lesions on MRI were present in 13 of the patients (43.4%). Comparison of the overall results recorded from patients with the healthy controls did not reveal a statistically significant difference in any of the parameters studied (p > 0.05). A significant inter-side difference was not also present between groups (p > 0.05). When p13 and n23 latencies exceeding 2.5 standard deviations (SD) were taken into consideration, it was seen that there were seven patients (23.3%) with prolonged latencies mainly involving the p13 peak. Five of them had brainstem signs on examination and had brainstem lesions on MRI. In the other eight patients with abnormal MRI, normal results were recorded indicating that in only 38% of patients with brainstem lesions, cVEMPs were altered. Absence of a correlation between cVEMPs and brainstem clinical or MRI lesions defies their role in identifying lower brainstem involvement.

Sildenafil-related cerebral venous sinus thrombosis and papilledema: a case report of a rare entity.

We present a rare case of cerebral venous sinus thrombosis associated with long-term and high-dose use of sildenafil. A 29-year-old man was referred to our neuroophthalmology clinic for bilateral visual deterioration and severe headache. He had stage 2 papilledema and other clinical and neurological examinations were normal. He had used the drug for nearly 2 years, two to three times a day. All laboratory parameters including blood count cell, coagulation panels, and genetic tests including methylene-tetrahydrofolate reductase and factor V Leiden mutation were unremarkable. The brain magnetic resonance imaging result confirmed transverse cerebral venous sinus thrombosis (CVST). The opening pressure of cerebrospinal fluid (CSF) was 43 cm H2O with normal biochemistry and no cells. Clinicians must be aware of the possibility of CVST when the patient uses sildenafil.

Idiopathic Intracranial Hypertension-A Comparison of Clinical Characteristics Between 4 Medical Centers in Different Geographic Regions of the World.

BACKGROUND: Idiopathic intracranial hypertension (IIH) is a well-characterized syndrome, most commonly affecting obese women of childbearing age. Differences in its prevalence have been reported in various populations. The aim of this article was to determine whether differences in clinical presentation and management exist for patients with IIH between different regions the world. METHODS: Retrospective database analysis of adult patients with IIH from 4 different neuro-ophthalmology clinics. The data collected included gender, age of onset, body mass index (BMI), lumbar puncture opening pressure, initial visual acuity (VA), initial visual field (VF) mean deviation (MD), pharmacological or surgical treatment, length of follow-up, final VA, and final VF MD. RESULTS: The study population consisted of 244 patients, with significant regional variations of female to male ratio. Overall, there was no significant difference regarding the age of diagnosis or the BMI. Acetazolamide was the first line of treatment in all groups but there was a difference between countries regarding second-line treatment, including the use of surgical interventions. Mean initial VA differed between groups but the final change in VA was the same among all the study groups. CONCLUSIONS: There are differences in IIH presentation, treatment, and response to therapy among different countries. International prospective studies involving multiple centers are needed to determine the potential influence of environmental and genetic factors on the development of IIH and to improve the management of this potentially blinding disorder.

Acetazolamide in vestibular migraine prophylaxis: a retrospective study.

The aim of this study is to check the efficacy of acetazolamide in the prophylaxis of vestibular migraine (VM). Treatment options in VM are mainly based on migraine guidelines. We tried to assess the efficacy of acetazolamide in these patients depending on clinical similarities with episodic ataxia type 2 and familial hemiplegic migraine responding to the drug. This is a retrospective cohort study. Among 50 patients with VM and prescribed acetazolamide 500 mg/day, 39 patients were studied as five had been lost on follow-up and six had stopped taking the drug due to side effects. Vertigo and headache frequency determined by number of attacks per month, and the severity determined by visual analog scales measured in centimeters from 0 to 10 were collected from the records. Initial reported figures for frequency and severity were compared with the results gathered after 3 months of treatment. The results were compared. Acetazolamide was effective in reducing both the frequency and severity of vertigo and headache attacks and this effect was more prominent for vertigo frequency and severity.

Association of leukoaraiosis with stroke recurrence within 5 years after initial stroke.

BACKGROUND: Leukoaraiosis (LA) is closely associated with stroke. Despite the fact that LA has consistently been shown to predict development of recurrent stroke, prior studies on the association of LA and stroke subtypes have been unsatisfactory. In this study, we sought to identify whether LA contributes to the recurrence of certain subtypes of stroke at long term. METHODS: Data from the Ege Stroke Registry were examined, and 5 years follow-up data for LA and stroke recurrence were analyzed. We performed survival curves using the Kaplan-Meier method (unadjusted) and log-rank tests in patients with stroke to determine the relationship between LA and recurrent stroke by stroke subtypes within a time period of 5 years. Multivariate survival analyses were undertaken using Cox proportional hazards models to determine the prognostic value of LA, stroke subtypes, and other vascular risk factors before recurrent stroke. RESULTS: Of 9522 patients with stroke, 1280 (26%) with LA and 901 (19%) without LA experienced a stroke recurrence within 5 years of follow-up (odds ratio, 1.53; 95% confidence interval, 1.39-1.69). After stratification by stroke subtypes, multivariable analysis revealed a significant association between LA and large artery disease (LAD; odds ratio [OR], 1.39; 95% confidence interval [CI], 1.18-1.64), small artery disease (SAD; OR, 1.57; 95% CI, 1.27-1.94), and intracerebral hemorrhage (ICH; OR, 1.88; 95% CI, 1.32-2.66), except cardioembolic stroke and "other" stroke subtypes at 5 years after stroke onset. The survival analysis showed that stroke recurrence was significantly higher in patients with severe LA compared with those with mild/moderate LA (log-rank test [Mantel-Cox], P < .001). CONCLUSIONS: Our results showed that LA is related to the recurrent strokes in patients with stroke within 5 years after stroke, specifically to the LAD, SAD and ICH.

Calcitonin gene-related peptide (CGRP) levels in peripheral blood in patients with idiopathic intracranial hypertension and migraine.

BACKGROUND: 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.

Prognostic predictors of remission in ocular myasthenia gravis.

BACKGROUND: Ocular myasthenia gravis (OMG) constitutes 15% of all myasthenia gravis patients. METHODS: One 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. RESULTS: Median 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. CONCLUSIONS: The 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.

Comparison of clinical features in patients with vestibular migraine and migraine.

Vestibular 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.

Risk for generalization in ocular onset myasthenia gravis: experience from a neuro-ophthalmology clinic.

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.

Vestibular migraine and persistent postural perceptual dizziness: Handicap, emotional comorbidities, quality of life and personality traits.

OBJECTIVE: 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 personality 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.

Vestibular migraine, demographic and clinical features of 415 patients: A multicenter study.

OBJECTIVE: 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.

Factors determining the response to treatment in patients with vestibular migraine.

PURPOSE: 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.
