Early diagnosis of Parkinson's disease (PD) is important for putative neuroprotective therapies to be initiated in the earliest stage of the disease. We investigated whether a previously validated timed motor test (TMT) battery could detect subtle motor dysfunction in early PD patients and even in clinically unaffected limbs of strictly hemiparkinsonian patients. We assessed 107 PD patients (symptom duration

Background: Motor performance is related to executive function, especially in dual tasks conditions. Thus, the aim of this study was to compare the results of Timed "Up and Go" test with and without dual task in older people with and without cognitive impairment according to verbal fluency test.
Method: A cross-sectional study was carried out in 291 elderly people attended by the Basic Health Unit of the city of Santos, São Paulo, Brazil.

Background: Individuals with mild cognitive impairment (MCI) commonly exhibit alterations in cortical structures accompanied by a mild decline in cognitive function. While the dual-task paradigm is utilized for MCI detection, its cortical mechanism remains incompletely understood. This study seeks to explore cortical structural changes and cognitive decline using the dual-task paradigm in individuals with MCI.

Co-speech gestures are also highly restricted in how they are timed with speech, typically synchronizing with prosodically-prominent syllables. What functional principles underlie this relationship? Here, we examine how the production of co-speech manual gestures influences spatiotemporal patterns of the oral articulators during speech production.

Introduction: This study aimed to investigate whether individualizing autonomic recovery periods between resistance training (RT) sessions (IND) using heart rate variability (HRV), measured by the root mean square of successive R-R interval differences (RMSSD), would lead to greater and more consistent improvements in muscle strength, muscle mass, and functional performance in older women compared to a fixed recovery protocol (FIX).
Methods: Twenty-one older women (age 66.0 ± 5.
Cerebral Amyloid-β Deposition, Axial Features, and Cognitive Alterations in Patients with Parkinson's Disease Treated with Bilateral STN-DBS: A Long-Term Cohort Study.

Our aim was to evaluate the possible long-term cerebral deposition of amyloid-β in patients with PD treated with subthalamic nucleus deep brain stimulation (STN-DBS) and its possible influence on axial and cognitive variables. Consecutive PD patients treated with bilateral STN-DBS with a long-term follow-up were included. The amyloid-β deposition was evaluated postoperatively through an 18F-flutemetamol positron emission tomography (PET) study.
