  1. ‘Woe Betides Anybody Who Tries to Turn Me Down.’ A Qualitative Analysis of Neuropsychiatric Symptoms Following Subthalamic Deep Brain Stimulation for Parkinson’s Disease.Philip E. Mosley, Katherine Robinson, Terry Coyne, Peter Silburn, Michael Breakspear & Adrian Carter - forthcoming - Neuroethics:1-17.
    Deep brain stimulation of the subthalamic nucleus for the treatment of Parkinson’s disease can lead to the development of neuropsychiatric symptoms. These can include harmful changes in mood and behaviour that alienate family members and raise ethical questions about personal responsibility for actions committed under stimulation-dependent mental states. Qualitative interviews were conducted with twenty participants following subthalamic DBS at a movement disorders centre, in order to explore the meaning and significance of stimulation-related neuropsychiatric symptoms amongst a purposive sample of persons (...)

    The critical aspects of deep brain stimulation are usually the focus of the ethical debate about the implantation of electrodes into the brain of patients with Parkinson’s disease. Above all, potential postoperative side effects on personality caused by DBS mark the debate. However, rehabilitation of agility and mobility by DBS can be posited against critical aspects. Therefore, the purpose of this article is to emphasize the hitherto neglected positive aspects of that technology. A detailed study of the rehabilitation of controlled (...)

Bardy & Simone Dalla Bella - 2021 - Frontiers in Psychology 12.
    Taking regular walks when living with Parkinson’s disease has beneficial effects on movement and quality of life. Yet, patients usually show reduced physical activity compared to healthy older adults. Using auditory stimulation such as music can facilitate walking but patients vary significantly in their response. An individualized approach adapting musical tempo to patients’ gait cadence, and capitalizing on these individual differences, is likely to provide a rewarding experience, increasing motivation for walk-in PD. We aim to evaluate the observance, safety, tolerance, (...)

  11. Incoming Ethical Issues for Deep Brain Stimulation: When Long-Term Treatment Leads to a ‘New Form of the Disease’.Frederic Gilbert & Mathilde Lancelot - 2021 - Journal of Medical Ethics 47 (1):20-25.
    Deep brain stimulation has been regarded as an efficient and safe treatment for Parkinson’s disease since being approved by the Food and Drug Administration in 1997. It is estimated that more than 150 000 patients have been implanted, with a forecasted rapid increase in uptake with population ageing. Recent longitudinal follow-up studies have reported a significant increase in postoperative survival rates of patients with PD implanted with DBS as compared with those not implanted with DBS. Although DBS tends to increase (...)

  14. Intraoperative Characterization of Subthalamic Nucleus-to-Cortex Evoked Potentials in Parkinson’s Disease Deep Brain Stimulation.Lila H. Levinson, David J. Caldwell, Jeneva A. Cronin, Brady Houston, Steve I. Perlmutter, Kurt E. Weaver, Jeffrey A. Herron, Jeffrey G. Ojemann & Andrew L. Ko - 2021 - Frontiers in Human Neuroscience 15.
    Deep brain stimulation of the subthalamic nucleus is a clinically effective tool for treating medically refractory Parkinson’s disease, but its neural mechanisms remain debated. Previous work has demonstrated that STN DBS results in evoked potentials in the primary motor cortex, suggesting that modulation of cortical physiology may be involved in its therapeutic effects. Due to technical challenges presented by high-amplitude DBS artifacts, these EPs are often measured in response to low-frequency stimulation, which is generally ineffective at PD symptom management. This (...)

    Clinical responses to dopamine replacement therapy for individuals with Parkinson’s disease are often difficult to predict. We characterized changes in MDS-UPDRS motor factor scores resulting from a short-duration L-Dopa response, and investigated how the inter-subject clinical differences could be predicted from motor cortical magnetoencephalography. MDS-UPDRS motor factor scores and resting-state MEG recordings were collected during SDR from twenty individuals with a PD diagnosis. We used a novel subject-specific strategy based on linear support vector machines to quantify motor cortical oscillatory frequency (...)

    Disability or health-related literature has potential to shape public understanding of disability and can also play an important role in medical curricula. However, there appears to be a gap between a health humanities approach which may embrace fictional accounts and a cultural disability studies approach which is deeply sceptical of fiction written by non-disabled authors. This paper seeks to reconcile these perspectives and presents an analysis of the language used by Jonathan Franzen in his description of Parkinson’s disease in the (...)

    Parkinson's disease patients receiving dopaminergic treatment may experience bursts of creativity. Although this phenomenon is sometimes recognized among patients and their clinicians, the association between dopamine replacement therapy in PD patients and creativity remains underexplored. It is unclear, for instance, whether DRT affects creativity through convergent or divergent thinking, idea generation, or a general lack of inhibition. It is also unclear whether DRT only augments pre-existing creative attributes or generates creativity de novo. Here, we tested a group of PD patients (...)

    Subthalamic nucleus deep brain stimulation is an established therapy for Parkinson’s disease motor symptoms. The ideal site for implantation within STN, however, remains controversial. While many argue that placement of a DBS lead within the sensorimotor territory of the STN yields better motor outcomes, others report similar effects with leads placed in the associative or motor territory of the STN, while still others assert that placing a DBS lead “anywhere within a 6-mm-diameter cylinder centered at the presumed middle of the (...)

    Leg rigidity is associated with frequent falls in people with Parkinson’s disease, suggesting a potential role in functional balance and gait impairments. Changes in the neural state due to secondary tasks, e.g., activation maneuvers, can exacerbate rigidity, possibly increasing the risk of falls. However, the subjective interpretation and coarse classification of the standard clinical rigidity scale has prohibited the systematic, objective assessment of resting and activated leg rigidity. The pendulum test is an objective diagnostic method that we hypothesized would be (...)

    There is evidence to suggest that some patients who undergo Deep Brain Stimulation can experience changes to dispositional, emotional and behavioural states that play a central role in conceptions of personality, identity, autonomy, authenticity, agency and/or self. For example, some patients undergoing DBS for Parkinson’s Disease have developed hypersexuality, and some have reported increased apathy. Moreover, experimental psychiatric applications of DBS may intentionally seek to elicit changes to the patient’s dispositional, emotional and behavioural states, in so far as dysfunctions in (...)

    Parkinson's Disease (PD) is a long-term degenerative disorder of the central nervous system that mainly affects the motor system. The symptoms generally come on slowly over time. Early in the disease, the most obvious are shaking, rigidity, slowness of movement, and difficulty with walking. Doctors do not know what causes it and finds difficulty in early diagnosing the presence of Parkinson’s disease. An artificial neural network system with back propagation algorithm is presented in this paper for helping doctors in identifying (...)

    The importance of religion in people's lives is due to the fact that religiosity is a very used mechanism to cope with all kinds of problems and especially those related to health, religion and therefore praying is a veridical mechanism for coping with stress. In Parkinson’s disease, the patients experience a wide variety of symptoms that address both the physical and the psychic and also a large variety of subsidiary diseases that can greatly influence the course of the basic disease (...)
