Coherence in resting-state EEG as a predictor for the recovery from unresponsive wakefulness syndrome.
We investigated differences of EEG coherence within (short-range), and between (long-range) specified brain areas as diagnostic markers for different states in disorders of consciousness (DOC), and their predictive value for recovery from unresponsive wakefulness syndrome (UWS). EEGs of 73 patients and 24 controls were recorded and coma recovery scale- revised (CRS-R) scores were assessed. CRS-R of UWS patients was collected after 12 months and divided into two groups (improved/unimproved). ⋯ Parietal coherence was significantly higher in delta and theta frequencies in the improved group, as well as the coherence between frontal and parietal regions in delta, theta, alpha, and beta frequencies. High parietal delta and theta, and high fronto-parietal theta and alpha coherence appear to provide strong early evidence for recovery from UWS with high predictive sensitivity and specificity. Short and long-range coherence can have a diagnostic value in the prognosis of recovery from UWS.

Biography Historical ArticleGiovanni Battista Morgagni (1682-1771).
Giovanni Battista Morgagni (1682-1771) is considered the father of neuropathology and one of the most important innovators in the history of medicine. In his "opus magnum" De sedibus et causis morborum per anatomen indagatis (The Seats and causes of diseases investigated by anatomy), he established pathological anatomy as a science by correlating clinical histories with autopsy findings.

Long-term impact on quality of life of subthalamic nucleus stimulation in Parkinson's disease.
Long-term impact of bilateral subthalamic nucleus deep brain stimulation (STN-DBS) on health-related quality of life (HRQOL) and associated factors in patients with Parkinson's disease (PD) are not clear. In this prospective study, we included 69 PD patients (64 % men, mean age 61.3 ± 7.4 and disease duration 13.2 ± 5.7 years) undergoing STN-DBS. They were evaluated preoperatively (baseline), 1 and 5 years postoperatively assessing 39-item Parkinson's Disease Questionnaire (PDQ-39), Schwab and England Activities of Daily Living Scale (SEADL), Unified Parkinson's Disease Rating Scale (UPDRS) off- and on-medication, patient diaries, dopaminergic treatment, mortality and surgical complications. ⋯ Lower preoperative PDQ-39 summary index and greater 1-year UPDRS-III-off total score gain predicted better long-term HRQOL. STN-DBS produces long-term improvements in HRQOL in PD. Preoperative HRQOL and short-term postoperative changes in off-medication motor status may predict long-term HRQOL in PD following STN-DBS.
