ABSTRACT Movement disorders in patients with Parkinson’s disease may require functional surgery, when medical therapy isn’t effective.
In Deep Brain Stimulation (DBS), electrodes are implanted within the brain to stimulate deep structures such as SubThalamic
Nucleus (STN). This paper describes successive steps for constructing digital atlases gathering patient’s location of electrode
contacts and clinical scores. Three motor and three neuro-psychological scores were integrated in the study. Correlations
between active contacts localization and clinical data were carried out using an adapted Hierarchical Ascendant Classification
and have enabled the extraction of clusters aiming to suggest optimum sites for therapeutic STN DBS. The postero-superior
region has been found to be effective for motor score improvement whereas the antero-inferior region revealed noticeable neuro-psychological
scores deterioration. Comparison with existing results has shown that such atlases are very promising for understanding phenomena

    ABSTRACT: Behavioural disturbances such as disorders of mood, apathy or indifference are often observed in Parkinson's disease (PD) patients with chronic high frequency deep brain stimulation of subthalamic nucleus (STN DBS). Neuropsychological modifications causing these adverse events induced by STN DBS remain unknown, even if limbic disturbances are hypothesised. The limbic system supports neural circuits processing emotional information. The aim of this work is to evaluate changes of emotional recognition in PD patients induced by STN DBS. Thirty PD patients were assessed using a computerised paradigm of recognition of emotional facial expressions [Ekman, P., & Friesen, W. V. (1976). Pictures of facial affect. Palo Alto, CA: Consulting Psychologists Press], 15 before STN DBS and 15 after. The two patients groups were compared to a group of 15 healthy control subjects. One series of 55 pictures of emotional facial expressions was presented to each patient. Patients had to classify the pictures according to seven basic emotions (happiness, sadness, fear, surprise, disgust, anger and no emotion). The intact ability to percept faces was firstly assured using the Benton Recognition Test. Recognition of fear expressions was significantly and selectively reduced in the post-operative group in comparison to both pre-operative and control groups. Our results demonstrate for the first time a selective reduction of recognition of facial expressions of fear by STN DBS. This impairment could be the first neuropsychological marker of a more general limbic dysfunction, thought to be responsible for the behavioural disorders reported after STN DBS.

    ABSTRACT: to analyse 24 parkinsonian patients successfully treated by bilateral STN stimulation for the presence of behavioural disorders. patients were evaluated retrospectively for adjustment disorders (social adjustment scale, SAS), psychiatric disorders (comparison of the results of psychiatric interview and the mini international neuropsychiatric inventory) and personality changes (IOWA scale of personality changes). parkinsonian motor disability was improved by 69.5% and the levodopa equivalent daily dosage was reduced by 60.5%. Social adjustment (SAS) was considered good or excellent in nine patients, moderately (n=14), or severely (n=1) impaired in 15 patients. Psychiatric disorders consisted of amplification or decompensation of previously existing disorders that had sometimes passed unnoticed, such as depressive episodes (n=4), generalised anxiety (n=18), and behavioural disorders with drug dependence (n=2). Appearance of mild to moderate emotional hyperreactivity was reported in 15 patients. Personality traits (IOWA scale) were improved in eight patients, unchanged in seven, and aggravated in eight Improvement in parkinsonian motor disability induced by STN stimulation is not necessarily accompanied by improvement in psychic function and quality of life. Attention is drawn to the possible appearance of personality disorders and decompensation of previous psychiatric disorders in parkinsonian patients who are suitable candidates for neurosurgery. We suggest that a careful psychological and psychiatric interview be performed before surgery, and emphasise the need for psychological follow up to ensure the best possible outcome.

    ABSTRACT: Many critical functionally distinct subcortical structures are not distinguishable on anatomical magnetic resonance imaging (MRI) scans. In order to provide the neurosurgeon with this missing information, a deformable volumetric atlas of the basal ganglia and thalamus has been created from the Schaltenbrand and Wahren atlas of cryogenic slices. The volumetric atlas can be automatically deformed to an individual patient's MRI. To facilitate the clinical use of the atlas, a visualization platform has been developed for preoperative and intraoperative use which permits manipulation of the merged atlas and MRI data sets in two- and three-dimensional views. The platform includes graphical tools which allow the visualization of projections of a leukotome and other surgical tools with respect to the atlas data, as well as preregistered images from any other imaging modality. In addition, a graphical interface has been designed to create custom virtual lesions using computer models of neurosurgical tools for intraoperative planning. To date this system has been employed as an adjunct to over 30 functional neurosurgical cases including surgery for movement disorders.
