Eligibility

Sex/Gender
Female
Age
35 Years to 65 Years

Inclusion criteria

Inclusion criteria: Dystonia patients will be included, if they have received DBS in the GPi, if they match the age range of 35-65 years and if they are female. Further, a pre-operative MRI or CT is required to locate the placement of electrodes using lead DBS.

Exclusion criteria

Exclusion criteria: Patients will be excluded from the study, if thy show any kind of cognitive impairment and/or if the electrode was not correctly placed in the GPi, according to LeadDBS.

Design outcomes

Primary

MeasureTime frame
The goal of this study is to provide a control group for already existing and also ethically approved data. To see whether the results can be replicated by stimulating correctly placed electrodes of the GPi, comparable cases need to be provided. The proposed study is considered purely experimental and is not aimed to give any therapeutic insight. Cognitive Performance is measured using four neuropsychological tests: Word-Pair learning, Digit ordering, stroop task and verbal fluency. All tests are done on three days under different stimulation conditions (no stimulation, 20Hz and 120 Hz Stimulation).

Secondary

MeasureTime frame
Secondary outcome are neurological examination and a wellbeing questionnaire.
