ConclusionsTogether, these results demonstrate the importance of personalized targeting and validate a set of microelectrode recording signatures to predict therapeutic activation volumes. These features may be used to improve the efficiency of deep brain stimulation programming and highlight specific neural oscillations of physiological importance.
There could soon be an eye test to aid in the assessment of Parkinsonâs disease. FDA has recently granted breakthrough device designation to a technology designed by RightEye that uses objective eye movement measurements to help detect the neurological disease. If the RightEye Vision System could gain a nod from FDA for detection,Â it would be a gamechanger because currently, no single test is capable of definitively diagnosing Parkinson's disease. Doctors instead rely on a variety of neurological examinations designed to confirm the clinical diagnosis, and misdiagnosis remains a continuing iss...
Subthalamic deep brain stimulation alleviates motor symptoms of Parkinson disease by activating precise volumes of neural tissue. While electrophysiological and anatomical correlates of clinically effective electrode sites have been described, therapeutic stimulation likely acts through multiple distinct neural populations, necessitating the need to characterize the full span of tissue activation. Microelectrode recordings have yet to be mapped to therapeutic tissue activation volumes and surveyed for predictive markers.
Conclusion: Medication and DBS both improved postural alignment in PD patients, but effects were small for the entire cohort. Patients with camptocormia according to the TCC angle benefit strongest. The large differences of the treatment effects may indicate distinct pathological mechanisms for stooped posture and postural disorders. The TCC angle was shown to be sensitive to change. The UCC angle was less sensitive but may be a useful assessment tool for a subgroup.
Subthalamic nucleus deep brain stimulation (STN DBS) is an established therapy for alleviating motor symptoms in advanced Parkinson's disease (PD) patients; however, a postoperative decline in cognitive and speech function has become problematic although its mechanism remains unclear. The aim of the present study was to elucidate the properties of language and drawing ability and cerebral perfusion in PD patients after bilateral STN DBS surgery.
MONDAY, Dec. 2, 2019 -- Some Parkinson's patients who have a deep brain stimulation device implanted to control their symptoms have reported an odd side effect -- they lost the ability to swim. Researchers report on the cases of nine patients who...
(Reuters Health) - A small study finds that some people lose their ability to swim when their Parkinson's disease is treated with deep brain stimulation.
Authors: Beszłej JA, Wieczorek T, Kobyłko A, Piotrowski P, Siwicki D, Weiser A, Fila-Witecka K, Rymaszewska J, Tabakow P Abstract Deep brain stimulation (DBS) is a treatment method that is currently getting more and more attention from psychiatrists. It has proven to be efficacious and safe in the treatment of neurological disorders, mainly Parkinson's disease (PD), dystonia and essential tremor. DBS has very often contributed to successful treatment in cases that had proved resistant to all other methods of treatment. Nowadays treatment-resistant obsessive-compulsive disorder (OCD) is the main psychiatric indica...
This article discusses how imaging improves surgical techniques and outcomes and widens possibilities in translational neuroscience in Parkinson disease, essential tremor, generalized dystonia, and epilepsy. In movement disorders diffusion tensor imaging allows anatomic segment of cortical areas and different functional subregions within deep-seated targets to understand the side effects of stimulation and gain more data to describe the therapeutic mechanism of action. The introduction of visualization of white matter tracks increases the safety of neurosurgical techniques in functional neurosurgery and neuro-oncology.
