RESUMEN
Idiopathic Parkinson's disease (PD) is a neurodegenerative disorder, characterized by motor and non-motor symptoms. Among non-motor symptoms we distinguish psychotic disorders, memory disorders, autonomic disorders. The aim: In this article, we want to draw attention to the most common symptoms of dysautonomy in Parkinson's disease, and the methods of their assessmen and therapy.

The aim of this study was to assess quantitatively sweating in PD patients. In the study, the galvanic-skin reaction (GSR) was used. The GSR was tested using eSense Skin Reaction device. The results show that sweating in patients with Parkinson's disease on drugs (PD ON) and control patients is similar, while patients with PD without levodopa (PD OFF) have higher perspiration.

INTRODUCTION: To date, there has been no clear evidence regarding the evaluation of saccades as a monitoring tool of motor impairment in Parkinson's disease (PD) Subthalamic Nucleus Deep Brain Stimulation (STN-DBS) patients. The aim of this study was to evaluate the long-term impact of STN-DBS and pharmacological treatment on reflexive saccades' (RS) parameters and UPDRS alterations. MATERIAL AND METHODS: The DBS group consisted of 20 PD patients who underwent bilateral STN-DBS. The Postoperative (POP) group consisted of 14 post-DBS patients. The Best Medical Therapy (BMT) group consisted of 20 patients on pharmacotherapy only. RS parameters and the UPDRS scale were measured during three visits in four phases of treatment (i.e. BMT-ON/OFF, DBS-ON/OFF). RESULTS: The significant UPDRS III and UPDRS. Total improvements were observed in all three study groups (p < 0.05), but RS latency improvement was stated only in the DBS group in the DBS-ON phase (p < 0.05). A significant correlation between RS latency increase and UPDRS III score worsening was found in all study groups, with the most evident effect in the UPDRS III ON phase (p < 0.05). CONCLUSION: RS parameters correlated with UPDRS III outcomes during the postoperative period in DBS-STN patients. Therefore, saccadic evaluation may be a good biomarker of the patient's response to surgical and/or pharmacological treatment.

The aim of this study was to assess the small bowel transit time in patients with Parkinson's disease (PD). Ten patients with PD with no gastrointestinal complaints and ten healthy control subjects were investigated using single photon emission computed tomography fused with computed tomography after swallowing of a specially prepared capsule containing technetium 99m, which allowed visualization of the passage in the intestines. Preliminary results show that the small intestine passage in PD patients was prolonged compared to controls.

INTRODUCTION: STN-DBS has been claimed to change progressionsymptomsin animal models of PD, but information is lacking about the possible neuromodulatory role of STN-DBS in humans. The aim of this prospective controlled study was to evaluate the long-term impact of STN-DBS on motor disabilities and cognitive impairment in PD patients in comparison to Best-Medical-Therapy (BMT) and Long-term-Post-Operative (POP) groups. MATERIAL AND METHODS: Patients were divided into 3 groups: the BMT-group consisted of 20 patients treated only with pharmacotherapy, the DBS-group consisted of 20 PD patients who underwent bilateral STN-DBS (examined pre- and postoperatively) and the POP-group consisted of 14 long-term postoperative patients in median 30 month-time after DBS. UPDRS III scale was measured during 3 visits in 9 ± 2 months periods (V1, V2, V3) in total-OFF phase. Cognitive assessment was performed during each visit in total-ON phase. RESULTS: The comparable UPDRS III OFF gain was observed in both BMT-group and POP-group evaluations (p < 0.05). UPDRS III OFF results in DBS-group revealed significant UPDRS III OFF increase in ΔV2-V1 assessment (p < 0.05) with no significant UPDRS III OFF alteration in ΔV3-V2 DBS-group evaluation (p > 0.05). Cognitive assessment revealed significant alterations between DBS-group and BMT-group in working memory, executive functions and learning abilities (p < 0.05). CONCLUSIONS: The impact of STN-DBS on UPDRS III OFF score and cognitive alterations suggest its neuromodulatory role, mainly during the first 9-18 months after surgery.

Background: Subthalamic nucleus deep brain stimulation (STN-DBS) has been an established method in improvement of motor disabilities in Parkinson's disease (PD) patients. It has been also claimed to have an impact on balance and gait disorders in PD patients, but the previous results are conflicting. Objective: The aim of this prospective controlled study was to evaluate the impact of STN-DBS on balance disorders in PD patients in comparison with Best-Medical-Therapy (BMT) and Long-term-Post-Operative (POP) group. Methods: DBS-group consisted of 20 PD patients (8F, 12M) who underwent bilateral STN DBS. POP-group consisted of 14 post-DBS patients (6F, 8M) in median 30 months-time after surgery. Control group (BMT-group) consisted of 20 patients (11F, 9M) who did not undergo surgical intervention. UPDRS III scale and balance tests (Up And Go Test, Dual Task- Timed Up And Go Test, Tandem Walk Test) and posturography parameters were measured during 3 visits in 9 ± 2months periods (V1, V2, V3) 4 phases of treatment (BMT-ON/OFF, DBS-ON/OFF). Results: We have observed the slowdown of gait and postural instability progression in first 9 post-operative months followed by co-existent enhancement of balance disorders in next 9-months evaluation (p < 0.05) in balance tests (Up and Go, TWT) and in posturography examination parameters (p < 0.05). The effect was not observed neither in BMT-group nor POP-group (p > 0.05): these groups revealed constant progression of static and dynamic instability (p > 0.05). Conclusions: STN-DBS can have modulatory effect on static and dynamic instability in PD patients: it can temporarily improve balance disorders. mainly during first 9 post-operative months, but with possible following deterioration of the symptoms in next post-operative months.
