About
The treatment of PD has made considerable advances in recent years with respect to drug therapies, as well as many new physiotherapy and drug-based methods, and there have also been great improvements in therapy thanks to deep brain stimulation. Cognitive rehabilitation has shown to be effective in PD (Abbruzzese et al., 2016), however, there has yet to be a major breakthrough in the treatment and prevention of PDD (Parkinson's Disease Dementia ). This is where the high frequency and intensive prevention described here comes into play.
Full description
Cognitive decline is an important and common complication in Parkinson's Disease (PD); approximately 27% of non-demented PD patients have Mild Cognitive Impairment (MCI) (Litvan et al. 2012, Chaudhuri et al., 2011) and up to 80% develop PD dementia (PD-D) over the long term (Hely et al., 2005). Cognitive course in PD is heterogeneous and affects visuospatial, attentional, executive and memory function; studies report different cognitive subtypes and divergent patterns of cognitive decline (Kehagia et al., 2010; Litvan et al., 2011; Williams-Gray et al., 2007; Yarnall et al., 2014). Recently, models have been constructed to estimate individual risk for global cognitive impairment using a small set of predictor variables (Liu et al. 2017; Velseboer et al., 2016). These prediction algorithms were developed in large samples of PD patients and accurately forecast cognitive decline in both, patients with MCI and patients with PD-D and were successfully replicated in independent samples; a score with a predefined cut off point predicts dementia with high positive and negative predictive values (Liu et al., 2017).
The primary aim of this study is the possible stabilization or delay of cognitive decline as well as the improvement of the quality of life of the patients. As secondary outcome, the change in symptoms associated with PD, will be investigated. Psychological states as depression and anxiety, as well as cognitive performance in different areas, for example attention and memory shall be investigated. Neurological symptoms, for example motor function and sleepiness, will also be assessed as secondary parameters and potentially confounding factors.
This study is a 4 week non-randomized controlled trial with one intervention group (HIPP) and one control group (CogniPlus). Primary and secondary outcome measures are assessed at baseline and are repeated after the 4-week intervention period and at 6 month in a follow-up assessment. After 4 weeks there is an intermediate measurement consisting of the primary outcome measures.
The intervention group receives individualized program: the program will be tailored to the patient's needs, strengths and weaknesses, resulting from the initial assessment.
- Tai Chi - "Keep Moving" is an exercise programme for patients with movement disorders that explicitly utilizes the health aspect of Tai Chi movement teachings. Each session lasted 60 minutes and ended with a 10-minute meditation. The Tai Chi sessions in our study were carried out twice a week under the guidance of certified Tai Chi instructors. Details of this program can be found on the following website: https://taiji-therapie.ch/
- CogniFit® - is a online-based personalized cognition training program. This well-validated cognitive training improves attention, working memory, memory, executive function, and visual perceptual functions. Each session lasted 20 minutes and was applied 2-5 times per week based on the results of the baseline tests. The home-based approach took place under the supervision of a psychologist or a specially trained psychology student. The difficulty level was automatically adjusted by the program itself. Details of the program can be found on the following website: https://www.cognifit.com/.
- SpeechCare - (MoveApp) is a home-based approach for patients with Parkinson's disease. The training program uses automatic speech recognition (ASR) and thus can provide feedback on speech intelligibility. Each session lasted 12 minutes and was conducted 1-3 times per week based on the results of the baseline test of SpeechCare . The domestic approach took place under the supervision of a psychologist or a specially trained psychology student. The level of difficulty was manually adjusted as needed. Details of the program can be found on the following website: https://www.speechcare.de/.
The patients in the control group received a computer-assisted cognitive training program: CogniPlus (Schuhfried GmbH, Vienna, Austria). Each training session consisted of different tasks (Focused attention; working memory; planning and action skill; respons inhibition) that were performed for 10 Minutes each. Details of the program can be found on the following website: www.schuhfried.at. The training sessions were supervised by a psychologist or a specially trained student of psychology
