The effect of aging, hearing loss, and tinnitus on white matter in the human auditory system revealed with fixel-based analysis

IntroductionAging negatively influences the structure of the human brain including the white matter. The objective of our study was to identify, using fixel-based morphometry, the age induced changes in the pathways connecting several regions of the central auditory system (inferior colliculus, Heschl’s gyrus, planum temporale) and the pathways connecting these structures with parts of the […]

Rescue subthalamic stimulation after unsatisfactory outcome of pallidal stimulation in Parkinson’s disease: a case series and review

BackgroundSubthalamic nucleus (STN) and globus pallidus interna (GPi) are two main structures primarily targeted by deep brain stimulation (DBS) to treat advanced Parkinson’s disease (PD). A subset of cases with unsatisfactory outcomes may benefit from rescue DBS surgery targeting another structure, while these patients’ characteristics have not been well described and this phenomenon has not […]

Residual effects of combined vibratory and plantar stimulation while seated influences plantar pressure and spatiotemporal gait measures in individuals with Parkinson’s disease exhibiting freezing of gait

IntroductionCombined plantar pressure and vibratory stimulation has been shown to decrease freezing of gait (FOG) episodes and improve spatiotemporal gait parameters compared to single stimulation in Parkinson’s disease (PD) patients with FOG. However, the effect of combined plantar stimulations on plantar pressure analysis has never been explored.MethodsForty PD patients with frequent FOG were allocated to […]
