It is thus advisable that patients receive psychiatric evaluation prior to DBS, and that psychiatric conditions

such as depression and anxiety receive adequate treatment preoperatively. As with psychiatric symptoms, the reported effects of DBS on cognition are variable. It is generally agreed that patients should receive cognitive screening as part of preoperative evaluation, since there have been reports of patients with poor cognitive function who became demented following DBS.92-94 In addition, DBS may be particularly likely to contribute Inhibitors,research,lifescience,medical to cognitive deficits in patients over age 69.95 Thus, the risks and benefits of the procedure should be weighed with particular care in these patients, for whom any further decline in cognition could greatly offset improvement of motor symptoms with DBS. Conclusion As we further our understanding Inhibitors,research,lifescience,medical of the neuropsychiatrie symptoms in PD, treatment of these patients has become more challenging. Although many agents are now available to treat motor symptoms in PD, less is known about safety and efficacy of treatment for behavioral symptoms, despite the fact that they affect, large numbers of patients and significantly contribute to morbidity Inhibitors,research,lifescience,medical and mortality in many cases. A multitude of psychiatric symptoms is seen in PD, including mood

changes, anxiety disorders, hallucinations, and Inhibitors,research,lifescience,medical frank psychosis. Changes in cognitive function are also seen, and, in some cases, progress to www.selleckchem.com/products/pexidartinib-plx3397.html development of dementia. Treatment of these behavioral symptoms can greatly improve patients’ overall function and reduce the burden placed on caregivers. Thus, despite the lack of formal treatment studies, clinicians

should make efforts to treat behavioral disturbances. Surgical interventions, such as DBS, are extremely beneficial for treatment of motor symptoms, but may worsen or cause behavioral symptoms. Patients should be evaluated carefully before DBS procedures and should also be Inhibitors,research,lifescience,medical monitored postoperatively for development of behavioral changes.
The he history of human postmortem studies in Parkinson’s disease (PD) begins at the end of the 1950s with two seminal papers: Carlsson’s original suggestion that dopamine (DA) may be a transmitter in the central nervous system (CNS) and be involved in the control of motor function, first and thus in the parkinsonian syndrome1 ; and the article by Ehringer and Hornykiewicz,2 which proved the significant, reduction in DA concentration in the neostriatum of patients suffering from sporadic PD. In 1973, these initial observations were followed by demonstration of a correlation between DA cell loss in the substantia nigra pars compacta (SNpc, Figure 1) and striatal DA concentrations in PD.
