Dysfunctional basal ganglia loops are thought to underlie the clinical picture of Tourette syndrome (TS). By altering dopaminergic activity in the affected neural structures, bilateral deep brain stimulation is assumed to have a modulatory effect on dopamine transmission resulting in an amelioration of tics. While the majority of published case reports deals with the application of bilateral stimulation, the present study aims at informing about the high effectiveness of unilateral stimulation of pallidal and nigral thalamic territories in TS. Potential implications and gains of the unilateral approach are discussed.

Renal fibrosis is the most common pathway for the development of end-stage renal disease (ESRD) in various kidney diseases. Currently, the treatment options for renal fibrosis are limited. Ferroptosis is iron-mediated lipid peroxidation, triggered mainly by iron deposition and ROS generation.

[Purpose] Although hallux function is fundamental in maintaining forward leaning standing posture, the insight into whether noncontact of the hallux with the ground alters the forward limit of stability (LoS) remains unclear. Thus, we aimed to determine the effects of the unilateral hallux noncontact on the forward LoS while standing. [Participants and Methods] This study included 17 healthy young and 17 community-dwelling older adults.

Persisting deficits are often seen years after an Achilles tendon rupture despite dedicated rehabilitation efforts. A possible reason for reduced function is elongation of the tendon and accompanying shortening of the muscle. Strength training with focus on the eccentric component of loading leads to longer muscle fascicles in healthy persons.

Objective: The objective of this review is to evaluate the effect of cochlear implants on cognitive function in pediatric patients with hearing loss.
Introduction: Cognitive impairments have been reported in children with hearing loss. This is supported by the auditory scaffolding hypothesis, which describes sound as the basis for processing sequential information.

Electroconvulsive therapy (ECT) is an effective treatment for depression but is often associated with cognitive side effects. In patients, ECT-induced electric field (E-field) strength across brain regions varies significantly due to anatomical differences, which may explain individual differences in cognitive side effects. We examined the relationship between regional E-field strength and change in verbal fluency score (i.
