[Backgroud - Deep brain stimulation (DBS) involves placing electrodes within specific deep brain nuclei. For movement disorders the most common indications are tremors, Parkinsons disease and dystonias. Surgeons mostly employ MR imaging for preoperative target selection. MR field geometrical distortion may contribute to target-selection error in the MR scan which can contribute to error in electrode placement. Methods - In this paper we compared the STN target planning coordinates in six parkinsonian DBS patients. Each patient underwent target planning in 1T and 3T MRI. We statistically compared and analysed the target-, and the fiducial coordinates in two different magnetic fileds. Results - The target coordinates showed no significant differences (Mann-Whitney test, p > 0.05), however we found significant difference in fiducial coordinates (p < 0.01), in 3T MRI it was more pronounced (mean ± SD: 0.8 ± 0.3 mm) comparing to 1T (mean ± SD: 0.4 ± 0.2 mm). Conclusion - Preliminary results showed no significant differences in planning of target coordinates comparing 1T to 3T magnetic fields.]

Evaluation of symptom severity, functional status and anxiety levels in patients with carpal tunnel syndrome with different electrophysiological stages

SEVINC Gürses Eftal, TEKESIN Aysel, TUNC Abdulkadir

Objective - The aim of this study was to evaluate the relationship between electrophysiological stage, symptom severity, functional status and anxiety levels in patients with idiopathic carpal tunnel syndrome (CTS). Materials and methods - This study included 130 patients in the 25-79 age group who were classified as clinically and electrophysiologically idiopathic carpal tunnel syndrome in our electromyography (EMG) laboratory. Visual Analog Scale (VAS) was used to assess pain during rest and activity. The Boston Carpal Tunnel Scale (BCTS) was used to evaluate symptom severity and functional status. Symptom Severity Scale (SSS) and Functional Capacity Scale (FCS) were assessed separately as a part of BCTS. Beck Anxiety Inventory (BAI) was used for anxiety assessment. Results - A total of 130 patients (25 males and 105 females) were enrolled to this prospective study. The mean age of the patients was 46.95 ± 10.57 years. When the electrophysiological stage was increased, it was found that SSS score and FCS score were increased (p <0.001). No significant correlation was detected between electrophysiological stage and VAS or BAI score. There was a positive correlation between VAS scores and SSS, FCS and BAI scores (p <0.001). Symptom severity and functional status were correlated with anxiety scores (p <0.001). SSS and FCS values of stage III and above patients were significantly higher than Stage I and II CTS patients (p <0.01). Conclusion - In conclusion, our study showed a significant correlation between symptom severity, functional status and anxiety in CTS patients. This can be interpreted as the mental deterioration of individuals with more severe symptoms. On the other hand, additional psychiatric support options should be recommended in cases of moderate findings but anxious symptoms. Electrophysiological findings shouldn’t be sufficient to measure the effect of the disease on the person.

[Neuropsychological rehabilitation following acquired brain injury]

TAMÁS Viktória, KOVÁCS Noémi, TASNÁDI Emese

[Neuropsychological rehabilitation or rehabilitation neuropsychology is a field within applied neuropsychology. It originally diverges from applied clinical and functional neuropsychology, although it could not be entirely differed from them. The unique nature of this area over the complexity is given by its process-controlled and system-approach aspects. In Hungary the number of neurorehabilitation centres and departments requiring neurocognitive rehabilitation has been continually increasing. Nevertheless, the number is still low; accordingly in our country this field is relatively young and isn’t well known. Authors of this review would like to draw attention to the importance of rehabilitation of patients with acquired brain injury and improvement of their quality of life with the theoretical and practical knowledge, as well as the necessity of future alterations and challenges emphasizing the need of a significant change of this narrow domain. ]

Psychoform and somatoform dissociative experiences in migraine: relationship with pain perception and migraine related disability

SENGUL Yildizhan, SENGUL Serdar Hakan, TUNC Abdulkadir

Objective - Migraine is a common and often debilitating disorder. Although the existence of a link between migraine and certain psychological features has long been known, data on dissociative experiences in migraine patients is insufficient. The aim of this study was to evaluate the presence of psychoform and somatoform dissociative experiences among migraine patients without aura and to examine their relationship with pain perception and disability. Methods - A total of 110 outpatients diagnosed with migraine based on the International Classification of Headache Disorders-III (ICHD-III) criteria and 70 healthy subjects were enrolled to this study. Sociodemographic data, Somatoform Dissociation Questionnaire (SDQ), Dissociative Experience Scale (DES), Beck Depression Inventory (BDI), and Beck Anxiety Scale (BAS) scores were recorded for each patient. The Migraine Impairment Disability Assessment Scale (MIDAS) and Visual Analog Scale (VAS) scores were also determined. Results - The mean SDQ and DES scores were significantly higher in migraine patients (p<0.001, p<0.01). According to SDQ, somatoform dissociation disorder, dissociative disorder not otherwise specified, and dissociative identity disorder were considered in 29.4%, 18.3%, and 10.1% of the migraine patients, respectively. Also, 20.9% of the patients had possible psychoform dissociation according to DES. A significant positive correlation was found between DES, SDQ scores, and VAS, MIDAS scores. Patients were found to have statistically significantly higher levels of depression and anxiety symptoms compared to healthy controls (p < 0.001). Higher DES and SDQ scores were associated with increased disability and pain level (p<0.01). Conclusion - Our findings seem to confirm the increased occurrence of somatoform and psychoform dissociative experiences in migraine patients. This study was intended as a beginning towards understanding dissociative experiences in migraine.

Inflammatory biomarkers in benign paroxysmal positional vertigo: A Turkey case-control study

AYSEL Tekeşin, ABDULKADIR Tunç

Objective - Benign paroxysmal positional vertigo (BPPV) is the most common cause of recurrent vertigo. Inflammation is a hypothetic etiological factor in BPPV. The aim of this study was to evaluate inflammatory biomarker levels in BPPV patients and compare these with the healthy subjects. Materials and methods - This prospective case-control study was conducted with 114 newly diagnosed BPPV patients and age- and sex- matched 83 healthy subjects. The laboratory investigations included serum hemogram, full biochemistry profiles, vitamin levels, thyroid hormone profiles, high sensitivity C-reactive protein (hsCRP) and erythrocyte sedimentation rate (ESR). Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte to HDL-cholesterol ratio (MHR) values were calculated and compared between the patients and healthy subjects. Results - The mean age was 39.1 ± 12.4 years for patients, and 37.0 ± 11.9 for controls. Vitamin B12, hematocrit (Hct), creatinine, urea, and fT4 values, lymphocyte, total bilirubin, direct bilirubin and indirect bilirubin levels were significantly lower in BPPV patients (p ˂ 0.05), while HDL, SGOT, and ESR values were significantly higher. In the BPPV patients the mean NLR, PLR, and mean platelet volume (MPV) values were significantly higher than in the control subjects. Neutrophil, platelet, monocyte, MHR, and CRP values were similar in both groups (p ˃ 0.05). Conclusion - Our result suggests that NLR, PLR, MPV, ESR, and bilirubin levels should be taken into account as potential biomarkers of BPPV. As they are inexpensive parameters and widely available, they can be used in clinical practice for prediction of BPPV. However, further large-scale studies are required to confirm this relationship.

TEKESIN Aysel, TUNC Abdulkadir, GÜNGEN Dogan Belma, AVCI Nalan, BAKIS Muhammed, PERK Seyma

Objective - The increasing prevalence of dementia over the previous decades has been accompanied by numerous social and economic problems. The importance of exercise in the prevention of dementia coupled with the impact of aspiration pneumonia on the mortality and morbidity of dementia patients cannot be overstated. This study investigates the effects of pulmonary rehabilitation combined with aerobic stretching exercises on the cognitive function, life quality, effort capacity, and level of depression in patients with mild cognitive impairment (MCI) in the early stages of dementia. Methods - Sixty-nine patients with MCI diagnosis were routinely monitored, and six were excluded because they did not attend the follow-up appointments. The remaining 63 patients undertook pulmonary physiotherapy (PPT) and extremity exercises for six months. The mini-mental state examination (MMSE), six-minute walk test (6MWT), Nottingham health profile (NHP), and Beck depression inventory (BDI) scores were evaluated before and after exercise. Results - PPT plus extremity exercises appeared to significantly improve the MMSE scores and increase the 6MWT (p < 0.001) by an average of 25 m. No significant improvement was observed in the BDI and NHP scores. Conclusion - PPT and aerobic exercise positively affected the cognitive ability of MCI patients and improved their walking distance. These results underscore the importance of combining medical treatment with physical rehabilitation at the onset of dementia, a disease which exerts a significantly negative impact on the economy.

[Earlier and more efficiently: the role of deep brain stimulation for parkinson’s disease preserving the working capabilities]

DELI Gabriella, BALÁS István, KOMOLY Sámuel, DÓCZI Tamás, JANSZKY József, ASCHERMANN Zsuzsanna, NAGY Ferenc, BOSNYÁK Edit, KOVÁCS Norbert

[Background – The recently published “EarlyStim” study demonstrated that deep brain stimulation (DBS) for the treatment of Parkinson’s disease (PD) with early fluctuations is superior to the optimal pharmacological treatment in improving the quality of life and motor symptoms, and preserving sociocultural position. Our retrospective investigation aimed to evaluate if DBS therapy was able to preserve the working capabilities of our patients. Methods – We reviewed the data of 39 young (<60 years-old) PD patients who underwent subthalamic DBS implantation at University of Pécs and had at least two years follow-up. Patients were categorized into two groups based on their working capabilities: Patients with active job (“Job+” group, n=15) and retired patients (without active job, “Job-” group, n=24). Severity of motor symptoms (UPDRS part 3), quality of life (EQ-5D) and presence of active job were evaluated one and two years after the operation. Results – As far as the severity of motor symptoms were concerned, similar (approximately 50%) improvement was achieved in both groups. However, the postoperative quality of life was significantly better in the Job+ group. Majority (12/15, 80%) of Job+ group members were able to preserve their job two years after the operation. However, only a minimal portion (1/24, 4.2%) of the Job- group members was able to return to the world of active employees (p<0.01, McNemar test). Conclusion – Although our retrospective study has several limitations, our results fit well with the conclusions of “EarlyStim” study. Both of them suggest that with optimal timing of DBS implantation we may preserve the working capabilities of our patients.]

[Efficacy of deep brain stimulation in our patients with Parkinson’s disease]

GERTRÚD Tamás, TAKÁTS Annamária, RADICS Péter, RÓZSA Ildikó, CSIBRI Éva, RUDAS Gábor, GOLOPENCZA Péter, ENTZ László, FABÓ Dániel, ERÕSS Loránd

[Background and purposes - In advanced Parkinson’s disease, medically refractory motor fluctuation or medically resistant tremor considerably affects quality of life. However, these symptoms can be mostly successfully treated by deep brain stimulation. We analyzed the efficacy of bilateral subthalamic stimulation in our patients with Parkinson’s disease. Methods - We assessed the clinical data of ten patients who have been treated in the Department of Neurology, Semmelweis University and have been operated in the National Institute of Neurosciences between 2008 and 2011. The Hoehn-Yahr scale score, the Unified Parkinson’s Disease Rating Scale score and the Parkinson’s Disease Questionnaire 39, as well as the dose of antiparkinson medication were documented prior to and one year after surgery. Results - Patient condition improved according to the Hoehn-Yahr scale, approximately by two stages. The dose of antiparkinson medication could be reduced by 63.4% (p=0.005) post operation. Unified Parkinson’s Disease Rating Scale scores decreased by 70.9% (p=0.005). 12 hours after medication withdrawal, execution of daily activity improved by 57.1% (p<0.01) and motor functions developed by 79.1% (p<0.01). Duration of dyskinesias decreased by 62.5% (p=0.018), duration of akinesia diminished by 87.5% (p=0.005). Quality of life rose by 41.6% (p<0.01). Neuropsychological tests detected improvement in verbal memory. Conclusion - With deep brain stimulation, the dosage of antiparkinson medication could be significantly reduced, with considerable improvements in motor function and quality of life. Although the number of patients is still low, good results have been established by careful patient selection, precise neurosurgical procedure and by appropriate programming and patient care.]

KOVÁCS Norbert

[Due to the recent developments in medicine, Parkinson’s disease became a relatively well-treatable condition. Recently the working abilities and the health-related quality of life of our patients dramatically improved by the application of optimal pharmacological and functional neurosurgical treatment options. Despite of these good progresses, the curative treatment option is still warranted. The aim of this review article is to present those pharmacological, neurosurgical and other treatments, which can improve the condition and quality of life of the patients. We also discuss the major concerns important for general practitioners including the assessment of driving abilities.]
