The Montreal Cognitive Assessment (MoCA) was administered at baseline and during annual follow-up visits over at least five years to determine if participants remained intact (MoCA ≥ 26) or developed CI (MoCA ≤ 25) or dementia (MoCA ≤ 21). Participants also completed a neuropsychological battery at baseline and again after a one-year interval. Practice effects on the cognitive tests across one-year were quantified with standardized regression-based change scores using PPMI data from cognitively intact subjects without PD. <b>Results:</b> Based on MoCA scores, 39% of patients developed CI and 10% developed PDD during the study. Linear regressions revealed smaller practice effects across one year in people with PD than in controls. Within the PD group, Cox regression analyses showed that smaller practice effects on tests of various cognitive domains were associated with an increased risk for CI. For PDD, only practice effects on a measure of processing speed significantly predicted cognitive outcomes. <b>Conclusions:</b> These findings demonstrate that practice effects have prognostic value in long-term cognitive outcomes in PD. This has important implications for clinical care and research, as one-year practice effects could help identify individuals at risk for CI and PDD and enrich samples for future clinical trials.

A challenge in the evaluation of potentially disease delaying, preventing, or reversing agents is identification of patients in the very early, prodromal (asymptomatic, non-motor, or early motor) stages, which can span decades. Currently, diagnosis is based almost exclusively on clinical history and physical examination conducted by trained experts. Unfortunately for many patients, access to neurology and movement disorder specialists is geographically limited and coupled with the absence of coordinated disease awareness campaigns can contribute to substantial delays in diagnosis. As with any campaign, a key success factor is having multiple approaches which can appeal to a wide range of patient archetypes. Herein we elaborate on some emerging opportunities, which if fully developed could invigorate the approach to early detection and, critically, engage patients in this process. They include 1) Use of personal digital health technologies and community based point-of-care diagnostic instrumentation, 2) The potential to leverage annual testing services at non-traditional venues including optometry, dental and pharmacy, and 3) A consumer focused campaign to raise awareness of the importance of early detection, paralleling efforts in other diseases. There is every hope that combining traditional and non-traditional approaches to enhance early diagnosis rates can have an overall positive impact on patient outcomes and contribute substantively to efforts to develop new interventions.

In the context of healthy aging and neurodegenerative disorders, such as Parkinson's disease (PD) engagement in dual tasking frequently results in impaired gait or upper limb performance, thereby affecting functional independence. Transcranial electrical stimulation is a non-invasive technique able to modulate brain activity, which might represent a potential tool for reducing dual task interference. The goal of this review is to provide a comprehensive summary of the most recent findings about the use of transcranial electrical stimulation in improving dual tasking in the elderly and people with PD, including considerations about the optimal stimulation parameters. Differences in terms of stimulation protocols emerged across the included studies. Among transcranial electrical stimulation techniques, transcranial direct current stimulation (tDCS) was the most frequently employed. Currently, using tDCS to target dorsolateral prefrontal cortex either alone or in a multi-site fashion, along with a concurrent complex task, appears to be the most promising method for reducing dual task interference.
