Computerized Cognitive Rehabilitation of Patients With Cognitive Deficits Due to the Human Immunodeficiency Virus

This is an exploratory Randomized Controlled Trial with the purpose of evaluating the potential of two sets of gamified cognitive and physical exercises in the neurorehabilitation of cognitive deficits due to an infection with the Human Immunodeficiency Virus (HIV). Upon recruitment, eligible study participants (see 'Eligibility Criteria') receive a detailed oral and written description about the scientific background, aims and methods of the study. Additional information will be provided about potential benefits and risks associated with study participation, as well as about the voluntary nature of participation throughout the study. The participant's written informed consent is required for study enrollment. After inclusion in the study, participants are randomized into one of two different training programs with equal chance of attribution and without possibility of choosing: * Program 1 involves brain training and guided, light physical exercise games on a tablet device. The exercise involves movements such as reaching, stepping, and stretching. Warm-up and cool down sessions are mandated prior to and following the tasks. * Program 2 involves gamified exercises displayed on a large screen. Participants use whole-body movements to complete the tasks. Tasks involve movements such as reaching, stepping, and jogging in place. These movements are tracked by a motion sensor. Warm-up and cool down sessions are mandated prior to and following the training sessions. Independently of program attribution, participants engage in a pre-training assessment, a six-week training period, a post-training assessment and a 6-month-follow-up assessment. Before the start of the training, participants are required to perform several cognitive and physical tests (including cyclo-ergospirometry) and fill out a number of questionnaires on subjective cognitive function, mood and quality of life. Additionally, an electroencephalography (EEG) will be performed to measure brain activity. The exercises, the questionnaires and the EEG serve as a baseline evaluation of cognitive, physical and neurophysiological function. Following the first assessment, study participants engage in a six-week training period. In both programs, participants engage in two weekly trainings of ninety minutes duration each. After completion of the training period, study participants engage in a post-training assessment to evaluate the effect of training on cognitive and physical performance. This session incorporates the same tasks and questionnaires as in the pre-training visit. An EEG will be used to characterize the training effects on dynamics of the underlying large-scale neuronal networks. The aim of the post-training assessment is to demonstrate immediate training effect of the two programs. A final follow-up visit is scheduled 6 months after the completion of the last training session. The cognitive and physical testing together with the questionnaires and the EEG will be repeated to examine the long-term effects of the training programs.
