Summery The underlying mechanisms of weight gain and other affective and cognitive changes after initiation of deep brain stimulation in Parkinson's disease are still unclear. Considering the functional organization within the subthalamic nucleus (STN); limbic, associative and sensorimotor regions residing in the medial, central and later STN respectively, we hypothesized that weight gain may be related to medial localization of stimulation, while motor improvement may be related to lateral localization of stimulation within the STN (study 1). We further hypothesized that stimulation close to the limbic and associative part of the STN may be associated with negative impact on limbic system leading to enhanced anxiety and changes in the hypothalamic- pituitary- adrenal axis (HPA)(study 2). Therefore, the primary aims our study were to assess changes in body weight (study 1) and the hypothalamic- pituitary- adrenal axis (HPA) (study 2) in relation to the position of the active stimulating contact within the nucleus. ...
