    The interplay between cholinergic activity, attention, and turning in Parkinson’s disease

    R. Morris, D. Martini, G. Mcbarron, M. Mancini, F. Horak (Portland, OR, USA)

    Objective: Explore how cholinergic activity (measured by short latency afferent inhibition [SAI]) and attention relate to quality of turning performance over a week of daily…

    Meta-Analysis of Short-afferent inhibition and Cognitive Impairment in Parkinson’s Disease

    J.F. Martin-Rodriguez, P. Mir (Seville, Spain)

    Objective: In this meta-analysis, we assess whether short-afferent inhibition (SAI) is impaired in Parkinson's disease (PD) patients as well as identify clinical variables associated to…
