    SEMINAR PAPER DTM Chan Surgical management of Parkinson’s VCT Mok WS Poon disease: a critical review KN Hung XL Zhu ○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○ !"#$%&'()*+, Parkinson’s disease is a progressive disabling movement disorder that is characterised by three cardinal symptoms: resting tremor, rigidity, and bradykinesia. Before the availability of effective medical treatment with levodopa and stereotactic neurosurgery, the objective of surgical management was to alleviate symptoms such as tremor at the expense of motor deficits. Levodopa was the first effective medical treatment for Parkinson’s disease, and surgical treatment such as stereotactic thalamo- tomy became obsolete. After one decade of levodopa therapy, however, drug-induced dyskinesia had become a source of additional disability not amenable to medical treatment. Renewed interest in stereotactic functional neurosurgery to manage Parkinson’s disease has been seen since the 1980s. Local experience of deep-brain stimulation is presented and discussed in this paper. Deep-brain stimulation of the subthalamic nucleus is an effective treatment for advanced Parkinson’s disease, although evidence from randomised control trials is lacking. !"#$%&'()*+,-!./01$23456789:; Key words: !"#$%&'()*+,-./01'23456789:;< Electric stimulation; !"#$%&'()*+,-./01(23#45+6789: Globus pallidus/surgery; Parkinson disease; !"#$%&'()*+,-./012345678'9:;< Stereotactic techniques; !"#$%&'()*%+,-./0123)456789:; Subthalamic nuclei/surgery; !"#$%&'()*+,-.1980 !"#$%&'()* Thalamus/surgery !"#$%&'()*+,-./0123456789:;<=

  • Neurocognitive and Psychosocial Correlates of Ventroposterolateral Pallidotomy Surgery in Parkinson's Disease
    Neurocognitive and psychosocial correlates of ventroposterolateral pallidotomy surgery in Parkinson's disease Henry J. Riordan, Ph.D., Laura A. Flashman, Ph.D., and David W. Roberts, M.D. Department of Psychiatry and Section of Neurosurgery, Dartmouth Medical School, Dartmouth­Hitchcock Medical Center, Lebanon, New Hampshire The purpose of this study was to characterize the neuropsychological and psychosocial profile of patients with Parkinson's disease before and after they underwent unilateral left or right pallidotomy, to assess specific cognitive and personality changes caused by lesioning the globus pallidus, and to predict favorable surgical outcome based on these measures. Eighteen patients underwent comprehensive neuropsychological assessment before and after left-sided pallidotomy (10 patients) or right-sided pallidotomy (eight patients). The findings support the presence of frontosubcortical cognitive dysfunction in all patients at baseline and a specific pattern of cognitive impairment following surgery, with side of lesion being an important predictor of pattern and degree of decline. Specifically, patients who underwent left-sided pallidotomy experienced a mild decline on measures of verbal learning and memory, phonemic and semantic verbal fluency, and cognitive flexibility. Patients who underwent right-sided pallidotomy exhibited a similar decline in verbal learning and cognitive flexibility, as well as a decline in visuospatial construction abilities; however, this group also exhibited enhanced performance on a delayed facial memory measure. Lesioning the globus pallidus may interfere with larger cognitive circuits needed for processing executive information with disruption of the dominant hemisphere circuit, resulting in greater deficits in verbal information processing. The left-sided pallidotomy group also reported fewer symptoms of depression and anxiety following surgery.

The major manifestations of the disease consist of resting tremor, rigidity, bradykinesia and gait disturbances. Before the advent of Levodopa surgery was main stay of treatment of PD. Medical therapy is still the mainstay of treatment for Parkinson's diseasebut its prolonged use results in side effects like drug induced dyskinesia. In 1952 Dr. Lars Leksell introduced Pallidotomy that was successful in relieving many Parkinsonian symptoms in patients. Later on thalamotomy became widely accepted, replacing pallidotomy as the surgical treatment of choice for Parkinson's Disease. Thalamotomy had an excellent effect on the tremor, was not quite as effective at reducing rigidity rather bradykinesia was often aggravated by the procedure. Objective: Effectiveness of Pallidotomy in rigidity in medically refractory Parkinson’s disease and its complications. Study Design: Descriptive prospective case series. Setting of study: Department of Neurosurgery, Lahore General Hospital, Lahore. Duration: June 2013 to April 2016.

Kyritsis, Backil Sung Copy Editor: Monica Wang Production Editor: Jing Yu Abstract Parkinson’s disease (PD) is a neurodegenerative illness and has a common onset between the ages of 55 and 65 years. There is progressive development of both motor and non-motor symptoms, greatly affecting one’s overall quality of life. While there is no cure, various treatments have been developed to help manage the symptoms of PD. Management of PD is a growing field and targets new treatment methods, as well as improvements to old ones. Pharmacological, surgical, and therapeutic treatments have allowed physicians to treat not only the main motor symptoms of PD, but target patient-specific problems as they arise. This review discusses both the established and new possibilities for PD treatment that can provide patient-specific care and mitigate side effects for common treatments.
