Parkinson's Disease
Bell's test
Opis:
In Africa, few studies are interested in unilateral spatial neglect (NSU) in Parkinson's disease. However, this syndrome is a deficit to detect, respond to or orientate towards meaningful stimuli (Heil- man, KM 1973), observable after an injury affecting the non-dominant hemisphere for language. The significant handicap it entails justifies the need for early diagnosis and care. The NSU study is mo- tivated by its link with neurocognitive phenomena that are important on the theoretical level (attention, visuospatial and perceptual awareness). The objective is to study USN in Parkinson's pa tients, followed and hospitalized at the Neurology Department of Hassan II University Hospital in Fez. The visual-graphic test that has been used to detect this pathology is that of Bell's test. The test focuses on the detection of targets placed among several stimuli on a sheet of A4 paper. The material included 120 people: 60 Parkinsonian patients: 34 men (56,7%), and 26 women (43,3%) and 60 control subjects: 34 men (56,7%), and 26 women (43,3%). The groups were matched by age and sex. Different aspects of neglect have been observed throughout the Bell's test. It was found that total omission of bell figures was significantly influenced by age, being less frequent in the 35-49 age group in both groups, and higher in the elderly (50-80 years), as well the level of education. It have been reduced considerably with the increase in education. The hand used and the laterality had no effect; t = 3.76 degrees of freedom (df) = 108.27 and p = 0.000. Unilateral spatial neglect has a negative effect in subjects with Parkin- son's disease. It deserves to be systematically sought for a better clinical evaluation and therapeutic management of the patients.

Opis:
Parkinson's Disease (PD) is the second most common neurodegenerative disease. Symptoms relate to the movement and cognitive sphere; they have a negative impact on the quality of life of people suffering from PD. Pharmacotherapy and rehabilitation slow the progression of the disease. The aim of the work was to determine the impact of physical rehabilitation on the level of social relations in the context of the quality of life of people with PD. 47 people with idiopathic PD were involved in the study, all were in the second stage of the disease according to the Hoehn & Yahr scale. The Courage Social Network Index (CSNI) was used to assess social relations. The scales: Quality of Life in Parkinson’s Disease 39 (PDQ-39), Medical Outcomes Study 36-item Short-Form Heath Survey (SF-36) and Parkinson’s Disease Quality of Life Questionnaire (PDQL) were applied in order to evaluate the quality of life of patients The subjects were divided into two groups: research and control. The research group took part in a rehabilitation program two times a week for 45 minutes for three months. The control group did not participate in any form of physical rehabilitation. The results of the research showed a significantly higher level of social bonds as well as quality of life of people with PD participating in physical rehabilitation. At the same time, a higher level of correlation between the level of social bonds and the level of quality of life was found in the research group. Therefore, the positive impact of physical rehabilitation on the level of social bonds and the quality of life of people with PD constituted the conclusion of the work.

Opis:
Some people suffering from Parkinson Disease experience problems with gait and keeping stable posture. Sometimes they fall down, which can be dangerous. Statistics show that more than 50% of PD patients happen to fall. The rehabilitation of those patients is difficult and complicated and its most important elements are coordination and balance exercises. The factors predicting falls are the following: age, cognitive disturbances, troubles with eyesight, bowel and bladder incontinence, intake of drugs. According to Hoehn and Yahr, in stages III, IV and V a loss of balance or/and a loss of body stability control can be observed. In this review the common rules of comprehensive rehabilitation of the patients suffering from Parkinson Disease and the prevention of falls have been described. The paper also presents the use of stabilometry, posturometry and gait analysis for early diagnosis, rehabilitation and prevention of falls.
Co najmniej połowa pacjentów z chorobą Parkinsona ma doświadczenie związane z upadkiem, zaś w późniejszych stadiach choroby dotyka to dwóch spośród trzech chorych. Rehabilitacja chorych z chorobą Parkinsona, zwłaszcza w rozwiniętej postaci choroby, jest trudna i skomplikowana. Ważnym jej elementem są ćwiczenia koordynacyjno-równoważne i zapobieganie upadkom. W pracy poglądowej przedstawiono zasady kompleksowej rehabilitacji osób z chorobą Parkinsona, omówiono zasady profilaktyki upadków, zaprezentowano wykorzystanie stabilometrii, posturometrii i analizy chodu dla wczesnej diagnostyki, rehabilitacji i profilaktyki upadków.

Opis:
INTRODUCTION Parkinson's disease is neurodegenerative disease of the elderly, for which to this day an effective cure has not been found. Besides pharmacotherapy and Deep Brain Stimulation in PD, an increasingly supplementary treatment is exercise therapy like Nordic Walking (NW). MATERIAL AND METHODS 40 patients with PD taking part in the survey were divided into two equal groups in terms of gender and stage of the disease (II and III stage of the Hoehn and Yahr scale); the study group was subjected to 6 weeks of Nordic Walking training. The control group consists of persons without physical activity for 6 weeks. RESULTS In the NW group there was a statistically significant better improvement of the test parameters. CONCLUSIONS After the 6 week rehabilitation period, major improvement in terms of patient mobility functionality and gait parameters is visible.
WSTĘP Choroba Parkinsona ( Parkinson’s disease – PD) jest neurozwyrodnieniową chorobą wieku podeszłego, na którą do dziś nie wynaleziono skutecznego lekarstwa. Oprócz stosowanej farmakoterapii coraz częściej uzupełnieniem leczenia jest terapia ruchowa, w tym trening metodą Nordic Walking (NW). MATERIAŁ I METODY Badaniem objeto 40 pacjentów z PD, których podzielono na dwie równe grupy pod względem płci oraz stopnia zaawansowania choroby (II i III stopień skali Hoehn&Yahr). Grupę badawczą poddano 6-tygodniowemu treningowi metodą NW . Grupę kontrolną stanowiły osoby bez aktywności fizycznej przez 6 tygodni. W Y N I K I W grupie NW stwierdzono znamiennie statystycznie lepszą poprawę badanych parametrów. W N I O S K I Po 6-tygodniowym okresie usprawniania widoczna jest znaczna poprawa w zakresie funkcjonalności ruchowej pacjentów oraz parametrów chodu.

Opis:
The present review examines several neurological conditions and the problems posed by travelling to high altitude, and in particular whether the underlying disease is likely to worsen. The neurological conditions include migraine and other types of headaches, transient ischemia of the brain, occlusive cerebral artery diseases, intracranial haemorrhage and vascular malformations, intracranial space occupying mass, multiple sclerosis, peripheral neuropathies, neuromuscular disorders, epileptic seizures, dementia and Parkinson’s disease. Attempts will be made to classify the risk posed by each condition and to provide recommendations regarding medical evaluation, advice for or against travelling to altitude and effective prophylactic measures. Some individual cases should only be advised after careful examination and risk evaluation either in an outpatient mountain medicine service or by a physician with knowledge of travelling and high altitude risks. Recent developments in diagnostic methods and treatment of neurological conditions are also mentioned.

Opis:
The aim of this pilot study was to determine the baseline state of oxidative stress indices in patients with Parkinson's disease (PD). Peripheral blood samples of 15 PD subjects were analyzed and compared with ten age matched healthy controls. Patients with PARK2 mutations were also compared with PD patients without mutations. There was significant increase in malondialdehyde content and superoxide-dismutase (SOD) activity in peripheral blood parameters in PD patients (p < 0.05) in comparison to controls. These findings suggest an important role of oxidative stress in Parkinson's disease evolution and progress. No changes were observed in glutathione peroxidase and nitric oxide levels. We found significant correlation between SOD activity and lipid peroxidation when the biochemical data was further analyzed. In addition, significant increase in the levels of SOD among the PD patients with PARK2 mutations was observed, which can be ascribed to chronic oxidative stress induced by PARK2 mutations.

Opis:
The novel MAO-B inhibitor PF9601N, its cytochrome P450-dependent metabolite FA72 and l-deprenyl were studied as potential peroxynitrite (ONOO-) scavengers and nitric oxide synthase (NOS) inhibitors. The scavenging activity of these compounds was evaluated by measuring the oxygen consumption through peroxynitrite-mediated oxidation of both linoleic acid and brain homogenate. FA72, PF9601N and l-deprenyl caused a concentration-dependent inhibition of ONOO--induced linoleic acid oxidation with an IC50 value of 60.2 µM, 82.8 µM and 235.8 µM, respectively. FA72 was the most potent also in inhibiting ONOO--induced brain homogenate oxidation with an IC50 value of 99.4 µM, while PF9601N and l-deprenyl resulted weaker inhibitors in the same experimental model, showing an IC50 value of 164.8 and 112.0 µM, respectively. Furthermore, both the novel MAO-B inhibitor as well as its metabolite were able to strongly inhibit rat brain neuronal NOS (IC50 of 183 µM and 192 µM, respectively), while l-deprenyl at the highest concentration used (3 mM), caused only a slight decrease of the enzyme activity. Moreover, inducible NOS was strongly inhibited by FA72 only. All these results suggest that PF9601N could be a promising therapeutic agent in neurodegenerative disorders such as Parkinson's disease.

Opis:
A person with Parkinson's disease has bigger problems with maintaining the stability than the healthy person. Nordic Walking is a safe kind of physical activity for elderly people. The aim of this study is to present the influence of a 6-month therapy of the Nordic Walking on the imbalance and the risk of falls for 66-years-old patient with Parkinson's disease. On the basis of results of 4 tests, performed both at the beginning and at the end of the Nordic Walking therapy, we have made a comparison of patient’s changes before and after 6 months of rehabilitation. the DGI test, the PD patient received 18 points. After he got 22 points. In the Functional Reach Test ( FR), while attempting to reach forward, reached out for 23 cm before the therapy, and 31 cm after the therapy. In the test and go up the patient got a time of 63 seconds, after therapy the time was reduced to 45 s. Nordic Walking is a safe kind of physical activity for people with Parkinson's disease. It reduces muscle tension, and improves joint function.

Ocenia się, że dysartryczne zaburzenia mowy w chorobie Parkinsona występują u 70-90% chorych, a leczenie farmakologiczne przynosi niewielkie efekty. Celem pracy była analiza komputerowa wpływu postępowania logopedycznego na strukturę akustyczną dźwięków mowy w grupie chorych z rozpoznaniem choroby Parkinsona. Materiał stanowiło 10 chorych (6 kobiet, 4 mężczyzn, w wieku 59-75 lat, średnio - 68,2), z rozpoznaniem choroby Parkinsona i z zaburzeniami mowy o charakterze dysar-trycznym. Wszyscy byli leczeni preparatami L-dopy. Przeprowadzono u nich terapię z uwzględnieniem ćwiczeń fonacji, artykulacji; ukierunkowanych na zmniejszenie sztywności mięśni ust i twarzy oraz ćwiczeń oddechowych. W celu oceny skuteczności postępowania logopedycznego wykorzystano komputerową akustyczną analizę mowy, ze szczególnym uwzględnieniem następujących parametrów: selektywności poszczególnych elementów wypowiedzi, tempa oraz stabilności dźwięków mowy. W analizie akustycznej zastosowano programy komputerowe IRIS oraz Wavelab. Stwierdzono, że systematycznie stosowane postępowanie logopedyczne u pacjentów z rozpoznaniem choroby Parkinsona i towarzyszącymi zaburzeniami mowy o typie dysartrii wpływa na stabilizację wybranych parametrów akustycznych mowy oraz poprawę sprawności mowy, co znalazło potwierdzenie w akustycznej analizie komputerowej.
Dysarthria occurs in case of 70-90% of patients with Parkinson's disease (PD). Pharmacological treatment of this symptom is not effective enough. The aim of this work was the computer analysis of the influence of speech therapy on the acoustic structure of speech sounds in patients with Parkinson's disease. Material and methods: 10 patients (6 women and 4 men) aged from 59 to 75 years (mean age - 68.2) with PD and dysarthria were examined. All patients were treated by the L-Dopa and the logopedie examination was carried out. The administrated pronation and articulation exercises aimed to facial and oral muscle rigidity reduction. The breathing training was included in the therapeutic programme, as well. Computer speech analysis was applied for the evaluation of speech rehabilitation efficacy. Selectiveness of the individual parts of speech and stability of frequency estimation were analyzed using IRIS and Wavelab computer programs. Systematic logopedie therapy in PD patients with dysarthria influences the speech acoustic parameters and enables the speech efficiency improvement. Computer acoustic analysis allows to follow the therapy efficacy.

Opis:
Parkinson’s Disease (PD) is primary related to substantia nigra degeneration and, thus, dopamine insufficiency. L-DOPA as a precursor of dopamine is the standard medication in PD. However, disease progression causes L-DOPA therapy efficiency decay (on-off symptom fluctuation), and neurologists often decide to classify patients for DBS (Deep Brain Stimulation) surgery. DBS treatment is based on stimulating the specific subthalamic structure: subthalamic nucleus (STN) in our case. As STN consists of parts with different physiological functions, finding the appropriate placement of the DBS electrode contacts is challenging. In order to predict the neurological effects related to different electrodecontact stimulations, we have tracked connections between the stimulated part of STN and the cortex with the help of diffusion tensor imaging (DTI). By changing a contacts number and amplitude of stimulus (proportional in size to stimulated area), we have determined connections to cortical areas and related neurological effects. We have applied data mining methods to predict which contact (and at what amplitude) should be stimulated in order to improve a particular symptom. We have compared different data mining methods: Wekas Random Forest classifier and Rough Set Exploration System (RSES). We have demonstrated that the Weka classifier was more accurate when predicting the effects of stimulations on general neurological improvements, while RSES was more accurate when using specific neurological symptoms. We have simulated other effects of stimulation related to the interruption of pathological oscillation in the basal ganglia found in PD. Our model represents possible STN neural population with inhibitory and excitatory connections that have pathologically synchronized oscillations. High-frequency electrical stimulation has interrupted synchronization. something that is also observed in PD patients.

Opis:
Parkinson's disease is a recognizable clinical syndrome with a variety of causes and clinical presentations; it represents a rapidly growing neurodegenerative disorder. Since about 90 percent of Parkinson's disease sufferers have some form of early speech impairment, recent studies on tele diagnosis of Parkinson's disease have focused on the recognition of voice impairments from vowel phonations or the subjects' discourse. This paper presents a new approach for Parkinson's disease detection from speech sounds that are based on CNN and LSTM and uses two categories of characteristics. These are Mel Frequency Cepstral Coefficients (MFCC) and Gammatone Cepstral Coefficients (GTCC) obtained from noise-removed speech signals with comparative EMD-DWT and DWT-EMD analysis. The proposed model is divided into three stages. In the first step, noise is removed from the signals using the EMD-DWT and DWT-EMD methods. In the second step, the GTCC and MFCC are extracted from the enhanced audio signals. The classification process is carried out in the third step by feeding these features into the LSTM and CNN models, which are designed to define sequential information from the extracted features. The experiments are performed using PC-GITA and Sakar datasets and 10-fold cross validation method, the highest classification accuracy for the Sakar dataset reached 100% for both EMD-DWT-GTCC-CNN and DWT-EMD-GTCC-CNN, and for the PC-GITA dataset, the accuracy is reached 100% for EMD-DWT-GTCC-CNN and 96.55% for DWT-EMD-GTCC-CNN. The results of this study indicate that the characteristics of GTCC are more appropriate and accurate for the assessment of PD than MFCC.

Opis:
Neurodegenerative disorders are amongst the most dangerous diseases in modern society. At the end of 1990, adenosine receptor antagonists were used to block the adenosine A1 and A2A receptors causing less physical, cellular and molecular damage caused by Alzheimer’s and Parkinson’s diseases. In recent years, an increase in death rate caused by these diseases has been observed among people under 74. Caffeine, as NMDA receptor antagonist, prevents an uncontrolled influx of calcium ions into the interior of the cells exerting a neuroprotective effect and beneficial procognitive effects. There is much evidence that caffeine intake is associated with a reduced risk of Alzheimer’s and Parkinson’s diseases.

Cel pracy: Ocena wpływu ćwiczeń ruchowych na czynność mięśni działających na stawy kolanowe u pacjentów z chorobą Parkinsona. Grupa badana: 10 pacjentów (kobiet) z chorobą Parkinsona, średni wiek 72,9 lat (grupa badana), oraz 12 osób zdrowych (kobiety), słuchaczki Uniwersytetu Trzeciego Wieku, średni wiek 65,0 lat (grupa kontrolna). Metoda badań: Wykonano badania czynnościowe mięśni zginaczy i prostowników stawu kolanowego na stanowisku do badań izokinetycznych Biodex System 3 Multi Joint. Badania przeprowadzono przed przystąpieniem do usprawniania pacjentów leczonych z powodu choroby Parkinsona oraz po okresie dwóch miesięcy regularnych ćwiczeń. Wyniki: W grupie pierwszej, w przypadku prędkości kątowej 60%, uzyskano istotną poprawę wszystkich analizowanych parametrów mięśni zginaczy i prostowników, zarówno w obrębie kończyny dolnej prawej, jak i lewej. Natomiast w przypadku prędkości kątowej 1807s istotnie wzrosły analizowane parametry dla mięśni prostowników i zginaczy stawu kolanowego prawego oraz dla mięśni prostowników stawu kolanowego lewego. W grupie 2. nie stwierdzono żadnych istotnych różnic. Wnioski: Ćwiczenia ruchowe prowadzone u osób z chorobą Parkinsona poprawiają czynność mięśni kończyn dolnych, w związku z powyższym mogą zmniejszyć ryzyko występowania upadków oraz powikłań z nimi związanych.
The influence of the regular exercises on the function of lower extremities muscles acting on the knee joints in patients with Parkinson's disease. Subjects: 10 women with Parkinson's disease at the average age of 72,9 and 12 healthy females at the average age of 65,0 (control group). Methods: Biodex dynamometer was used to measure strength - velocity parameters in the knee flexors and extensors muscles. The examination were performed before the period of patients rehabilitation and after two months of regular exercises. Results: In a group 1, in case of the angular velocity of 60°/s, a significant improvement of all analyzed parameters of flexor and extensor muscles was obtained, both in the right and the left lower extremity. In the case of the angular velocity of 1807s, a significant increase of analyzed parameters of flexor and extensor muscles was noted. No significant differences were found in a group 2. Conclusions: Exercises in case of patients with Parkin-son's disease increase the muscular function of lower extremities and therefore may decrease the risk of falls and complications resulting from injures.

Opis:
The purpose of this article is to present speech disorders of 91 years old patient suffering from advanced Parkinson’s disease (it is the last stage of the disease when all symptoms are stronger) and to draw attention to the need of mentioning the impact of speech therapy while describing the disease. In the article an author is introducing the patient and her current condition. Mainly it is focused on the speech therapy diagnosis that was based on particular aspects of speech (such as: general condition of the patient, phonation, comprehension of speech and naming, repea- ting, dialogues and storytelling, reading, counting and writing). In the final part, the effectiveness of speech therapy is presented. This publication might become  a leading example for other speech therapist on how to manage the therapy for people suffering from these types of disorders in speaking and communication.
