[Early postoperative assessment of cognitive functions after stereotactic pallidotomy in patients with primary dystonia - preliminary results].
Bibliographic record
Abstract
BACKGROUND AND PURPOSE: The newest studies notify that globus pallidus, besides the motor control, plays an important role in cognitive functioning of: memory, attention, linguistic skills, visuospatial ability, and executive functions. Stereotactic pallidotomy (the lesion of the motor region of the globus pallidus) is one of the surgery options that is used in the treatment of the primary dystonia. Motor region is located in the postero-ventral part of the internal globus pallidus. The goal of the study was to assess of the influence of pallidotomy on cognitive functioning in the group of patients suffering from the primary dystonia. MATERIAL AND METHODS: Eighteen patients diagnosed with primary dystonia were treated by stereotactic pallidotomy and they were investigated neuropsychologically. The study was performed between March 2004 and February 2005. Neuropsychological assessment was conducted 1-2 days prior to operation and 2 days following the surgery. The clinical course of the cognitive functions and emotional status were assessed by the following neuropsychological tests: Mini Mental State Examination (MMSE), Trail Making Test A and B (TMT A and B), Stroop Color-Word Interference Test, N-back Test, Auditory Verbal Learning Test (AVLT), Benton Visual Retention Test (BVRT), Wisconsin Card Sorting Test (WCST), Beck Depression Inventory (BDI), Montgomery-Asberg Depression Rating Scale (MADRS). RESULTS: The statistically significant differences have been obtained between the results before and after the surgery in the depression scales: BDI (p<0.02) and in MADRS (p<0.01). None of the neuropsychological tests revealed significant differences between the results before and after the surgery. The only trend (p=0.06-0.07) was noted between results of AVLT before and after the surgery. The average results were worse after the surgery in the first, fifth and sixth attempt of the reply. CONCLUSIONS: Stereotactic pallidotomy has not significantly changed cognitive functions in the patients suffering from primary dystonia. Whereas, the emotional state has significantly improved in consequence of the applying surgery. Stereotactic pallidotomy in primary dystonia seems to be a treatment option safe for the patients' cognitive functions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
