Gait instability and compensatory mechanisms in Parkinson's disease with camptocormia: An exploratory study.
J Mov Disord
December 2024
Graduate School of Health Sciences, Kio University, Nara, Japan.
Objective: Camptocormia has been considered to contribute to vertical gait instability and, at times, may also lead to forward instability in experimental settings in Parkinson's disease (PD). However, these aspects, along with compensatory mechanisms, remain largely unexplored. This study comprehensively investigated gait instability and compensatory strategies in PD patients with camptocormia (PD+CC).

In recognising emotions expressed by others, one can make use of both embodied cognition and mechanisms that do not necessarily require activation of the limbic system, such as evoking from memory the meaning of morphological features of the observed face. Instead, we believe that the recognition of the authenticity of an emotional expression is primarily based on embodied cognition, for which the mirror system would play a significant role. To verify this hypothesis, we submitted 20 parkinsonian patients and 20 healthy control subjects to the Emotional Authenticity Recognition test, a novel test using dynamic stimuli to evaluate the ability to recognise emotions and their authenticity.

Olfactory dysfunction, affecting 75-90 % of Parkinson's disease (PD) patients, holds significant predictive value for PD development. Advanced imaging techniques, such as diffusion MRI (dMRI) and functional MRI (fMRI), offer insights into structural and functional changes within olfactory pathways. This review summarizes a decade of research on MRI-based connectivity of the olfactory system in PD, focusing on structural and functional alterations in olfactory brain areas and their links to early olfactory processing changes.

Spasmodic dysphonia (SD) is now generally considered to be a task-specific focal dystonia. For the first time, we wanted to explore the relationship between SD and dystonia from a combined neurological and phoniatric perspective. For this, we studied 115 patients with non-psychogenic SD by a combined neurological and phoniatric evaluation.

On July 6th of 1924 Hans Berger -a German psychiatrist- first recorded electric signals from the human brainvia scalp electrodes. This date marks the beginning of Electroencephalography. In this review a representative panel of past and present Officers of the International Federation of Clinical Neurophysiology (IFCN) and of its Official Journal briefly summarizes the past, present and future of Electroencephalographic and related neurophysiological techniques' impact and the role of the IFCN in global collaboration, education, standardization, research innovation, and clinical practice.
