NCT02225314.

Trial name or title	Computer‐based cognitive training for individuals with PD‐MCI
Methods	3‐arm RCT of computerised auditory and accuracy training vs visual processing and working memory training vs active control (n = 25).
Participants	People speaking English with a confirmed medical diagnosis of Parkinson's disease and meeting established criteria for MCI in PD (Litvan 2012), defined as individuals with performances of approximately 1 to −2 SDs below the mean on at least 2 tests within 5 cognitive domains assessed in clinical neuropsychological evaluations People with dementia are excluded.
Interventions	Treatment arm 1: computer‐based cognitive training known as Brain Fitness, which consists of 6 types of exercises that train auditory processing speed and accuracy Treatment arm 2: computer‐based cognitive training known as InSight, a computer‐based cognitive training programme that consists of 5 types of exercises that train visual processing and working memory 60 minutes per day, 5 days a week Active‐control training programme: computerised learning programme consisting of 5 programmes (i.e. Wright Brothers, History of Britain, Sister Wendy's American Collection, In Search of Shakespeare, and View the Cosmos) designed to improve knowledge about literature, art, and history.
Outcomes	Primary outcome: per cent accuracy on cognitive training quizzes (Brain Fitness; auditory processing and accuracy tasks; InSight: visual processing and working memory tasks) Secondary outcomes: PDQ‐39, California Verbal Learning Test‐II Long Delay Free Recall Scaled Score Change Outcomes measured at 3 months.
