Abstract [en]

Objective: The objectives of this study were to explore the changes in the activities of daily living (ADL) in persons with Parkinson's disease (pwPD) over time and to investigate possible differences in ADL performance between men and women with PD.

Materials & Methods: One hundred twenty‐nine persons (76 men) with a clinically established PD self‐assessed their ADL performance from the time of diagnosis up to 8 years follow‐up using the ADL taxonomy. Other demographic and clinical data (motor state, cognition, depression) were also collected and subjected to further analysis.

Results: Nine of 12 domains in the ADL taxonomy showed a change over time (Eating and Drinking [P = .009], Mobility [P < .001], Toilet activities [P = .031], Dressing [P < .001], Personal hygiene [P < .001], Communication [P < .001], Cooking [P = .001], Shopping [P < .001] and Cleaning [P < .001]). In addition to time, two domains, (Shopping [P = .007] and Cleaning [P = .027]) also showed an effect of gender with worse scores in women. The nine ADL domains showing effect of time, showed temporary improvement at 12 months follow‐up, most probably due to dopaminergic medication. All nine domains deteriorated at later follow‐up.

Conclusions: As expected, there was deterioration in self‐assessed performance in the majority od ADL domains over time. Women assessed their ADLs worse in two domains (Shopping and Cleaning) probably reflecting a general gender‐related activity pattern rather than being a PD‐specific finding.

Abstract [en]

Introduction: To offer people with Parkinson's disease optimal occupational therapy, it is important to have a detailed understanding of how they manage everyday life. The aims of this study were to explore how people with Parkinson's disease manage the effect of the disease on everyday life and to investigate gender similarities and differences concerning this issue.

Method: We interviewed 24 people with Parkinson's disease (14 men), at a mean of 8 years after diagnosis. The interviews were analysed according to Grounded Theory.

Findings: 'Striving to maintain a good everyday life' was established as a core category. To overcome obstacles caused by the disease, the interviewees struggled with perpetual adaptation to the medication regime and ongoing changes in their abilities. To achieve best possible everyday life, it was essential to keep their own spirit up; for example, by prioritising valued occupations. Women and men contributed to all categories and used the same strategies.

Conclusion: Men and women with Parkinson's disease used the same strategies to manage daily life challenges. Our findings support the relevance of disease-specific occupational therapy interventions focusing on the individual fit between person, environment and occupation, and highlight the need for joyful occupations to attain a satisfactory daily life.

Abstract [en]

Background: Several open-label studies have shown good effect of deep brain stimulation (DBS) in the caudal zona incerta (cZi) on tremor, including parkinsonian tremor, and in some cases also a benefit on akinesia and axial symptoms. The aim of this study was to evaluate objectively the effect of cZi DBS in patients with Parkinson's disease (PD).

Method: 25 patients with PD were randomised to either cZi DBS or best medical treatment. The primary outcomes were differences between the groups in the motor scores of the Unified Parkinson's Disease Rating Scale (UPDRS-III) rated single-blindly at 6 months and differences in the Parkinson's Disease Questionnaire 39 items (PDQ-39). 19 patients, 10 in the medical arm and 9 in the DBS arm, fulfilled the study.

Results: The DBS group had 41% better UPDRS-III scores off-medication on-stimulation compared with baseline, whereas the scores of the non-surgical patients off-medication were unchanged. In the on-medication condition, there were no differences between the groups, neither at baseline nor at 6 months. Subitems of the UPDRS-III showed a robust effect of cZi DBS on tremor. The PDQ-39 domains 'stigma' and 'ADL' improved only in the DBS group. The PDQ-39 summary index improved in both groups.

Conclusion: This is the first randomised blinded evaluation of cZi DBS showing its efficacy on PD symptoms. The most striking effect was on tremor; however, the doses of dopaminergic medications could not be decreased. cZi DBS in PD may be an addition to existing established targets, enabling tailoring the surgery to the needs of the individual patient.

Abstract [en]

Pallidal deep brain stimulation is an established treatment in patients with dystonia. However, evidence from case series or uncontrolled studies suggests that it may lead in some patients to specific parkinsonian symptoms such as freezing of gait, micrographia, and bradykinesia. We investigated parkinsonian signs using the Movement Disorder Society Unified Parkinson's Disease Rating Scale motor score by means of observer-blinded video ratings in a group of 29 patients treated with pallidal stimulation and a non-surgical control group of 22 patients, both with predominant cervical dystonia. Additional assessments included MRI-hased models of volume of neural tissue activated to investigate areas of stimulation related to dystonic symptom control and those likely to induce parkinsonian signs as well as an EMG analysis to investigate functional vicinity of stimulation fields to the pyramidal tract. Compared with controls, stimulated patients had significantly higher motor scores (median, 25th-75th percentile: 14.0, 8.0-19.5 versus 3.0, 2.0-8.0; P < 0.0001), as well as bradykinesia (8.0, 6.0-14.0 versus 2.0, 0.0-3.0; P < 0.0001) and axial motor subscores (2.0, 1.0-4.0 versus 0.0, 0.0-1.0; P= 0.0002), while rigidity and tremor subscores were not different between groups. Parkinsonian signs were partially reversible upon switching stimulation off for a median of 90 min in a subset of 19 patients tolerating this condition. Furthermore, the stimulation group reported more features of freezing of gait on a questionnaire basis. Quality of life was better in stimulated patients compared with control patients, but parkinsonian signs were negatively associated with quality of life. In the descriptive imaging analysis maximum efficacy for dystonia improvement projected to the posteroventrolateral internal pallidum with overlapping dusters driving severity of bradykinesia and axial motor symptoms. The severities of parkinsonian signs were not correlated with functional vicinity to the pyramidal tract as assessed by EMG. In conclusion, parkinsonian signs, particularly bradykinesia and axial motor signs, due to pallidal stimulation in dystonic patients are frequent and negatively impact on motor functioning and quality of life. Therefore, patients with pallidal stimulation should be monitored closely for such signs both in clinical routine and future clinical trials. Spread of current outside the internal pallidum is an unlikely explanation for this phenomenon, which seems to be caused by stimulation of neural elements within the stimulation target volume.

Abstract [en]

Objective: To explore, in female and male patients with medically treated, moderately advanced Parkinson's disease (PD), their knowledge and reasoning about Deep Brain Stimulation (DBS).

Methods: 23 patients with PD (10 women), aged 46- 70, were interviewed at a mean of 8 years after diagnosis, with open-ended questions concerning their reflections and considerations about DBS. The interviews were transcribed verbatim and analysed according to the difference and similarity technique in Grounded Theory.

Results: From the patients' narratives, the core category "Processing DBS: balancing symptoms, fears and hopes" was established. The patients were knowledgeable about DBS and expressed cautious and well considered attitudes towards its outcome but did not consider themselves ill enough to undergo DBS. They were aware of its potential side-effects. They considered DBS as the last option when oral medication is no longer sufficient. There was no difference between men and women in their reasoning and attitudes towards DBS.

Conclusion: This study suggests that knowledge about the pros and cons of DBS exists among PD patients and that they have a cautious attitude towards DBS. Our patients did not seem to endorse an earlier implementation of DBS, and they considered that it should be the last resort when really needed.

Abstract [en]

Available data indicate that there are gender differences in many features of Parkinson's disease (PD). Precise identification of the gender differences is important to tailor treatment, predict outcomes, and meet other individual and social needs in women and men with PD. The aim of this study was to review the available clinical data on gender differences in PD. Original articles and meta-analyses published between 1990 and 2016 systematically exploring gender differences in PD were reviewed. There is slight male preponderance in incidence and prevalence of PD. PD starts earlier in men. Women tend to be more prone to develop tremor-dominant PD but are less rigid than men. Motor improvement after deep brain stimulation is equal in both sexes, but women tend to show better improvement in activities of daily living. Furthermore, women with PD show better results on tests for general cognitive abilities, outperform men in verbal cognitive tasks, show more pain symptoms, and score higher on depression scales. It seems, however, that the differences in cognition, mood, and pain perception are not disease specific as similar gender differences can be found in healthy subjects and in other neurological conditions. Despite PD being the most frequently studied movement disorder, studies investigating gender differences in PD are still scarce with most of the studies being cross-sectional. Good-quality, prospective, longitudinal studies analyzing gender differences in PD and comparing them to matched healthy controls are needed in order to properly address the issues of gender differences in PD.

Abstract [en]

Objective. To evaluate a set of psychometric properties (i.e., data completeness, targeting, and external construct validity) of the Parkinson's disease Activities of Daily Living Scale (PADLS) in people with Parkinson's disease (PD). Specific attention was paid to the association between PADLS and PD severity, according to the Hoehn & Yahr (H&Y) staging. Methods. The sample included 251 persons with PD (mean age 70 [SD 9] years). Data collection comprised a self-administered postal survey, structured interviews, and clinical assessments at home visits. Results. Data completeness was 99.6% and the mean PADLS score was 2.1. Floor and ceiling effects were 22% and 2%, respectively. PADLS scores were more strongly associated (r(s) > 0.5) with perceived functional independence, ADL dependency, walking difficulties, and self- rated PD severity than with variables such as PD duration and cognitive function (r(s) < 0.5). PADLS scores differed across H& Y stages (Kruskal- Wallis test, p< 0.001). Those in H&Y stages IV-V had more ADL disability than those in stage III (Mann- Whitney U test p < 0.001), whereas there were no significant differences between the other stages. Conclusion. PADLS revealed excellent data completeness, acceptable targeting, and external construct validity. It seems to be well suited as a rough estimate of ADL disability in people with PD.

Abstract [en]

Background: Deep brain stimulation (DBS) is an established treatment for Parkinson's disease. However, patients' own perceptions of the impact of DBS on their daily living is not fully explored. 

Objective: We aimed to collect and analyse patients' narratives about their everyday experiences of being on chronic DBS. 

Methods: Semi-structured interviews with open-ended questions were conducted with 42 patients (11 women) who had been on DBS for a mean of three years. The questions were related to patients' ordinary daily life and eventual changes, both negative and positive, brought about by DBS. The interviews were transcribed verbatim and analysed according to the difference and similarity technique in grounded theory. 

Results: From the patients' narratives the core category `DBS means everything - for some time' was established, and supported by the following categories: 1) Relief from invasive tremor. 2) A rescue from cramps and pain. 3) Easier movement swings and more predictable living space. 4) Hard, but compared to previous suffering, bearable adverse events. 5) Parkinson's disease is progressing despite DBS. 

Conclusions: The analysis of the participants' narratives shed light on patients' unique perceptions and perspectives of the impact of DBS on their everyday lives. Patients with advanced PD highly appreciated the positive impact of DBS on their daily life even if this impact is limited in time. For the majority, the relief from the severe parkinsonian symptoms, especially tremor and painful cramps, outweighed the side effects of DBS. The study provided information not readily captured by pre-formulated questionnaires and scales.

Abstract [en]

Despite the success of deep brain stimulation (DBS) in various movement disorders, its use in Huntington´s Disease (HD) has been limited. So far, promising results of pallidal DBS have been reported in 7 patients with HD. We performed bilateral pallidal DBS in a 59 year old woman with HD since 12 years and severe motor symptoms. At the evaluation after 12 months the effect was deemed satisfactory mainly concerning the patient’s choreatic symptoms. However, the improvement according to the unified Huntington’s disease rating scale was modest, with a score reduction from 92 to 81.
