ABSTRACT
Background
Computerized Cognitive Training (CCT) is an effective treatment for cognitive impairment in the post-acute stage of stroke. However, it is still not clear if it is suitable for chronic stage.
Objectives
To explore if patients with cognitive deficit following stroke may benefit from CCT.
Methods
Thirty patients post-stroke between 24 and 62 years old were randomized into two groups (A and B) to receive two different types of CCT. All patients were tested with a neuropsychological battery and functional questionnaires, before and after each CCT and also 6 months after the end of the study. In phase I, Group A received a customized CCT and Group B received a non-customized CCT, over 6 weeks. Three months after, each group received the other intervention (phase II).
Results
After phase I, between-group analyses revealed that Group A showed a relative decrease in subjective complaints. In contrast, Group B showed improvement in performance-based measures. After phase II, the decrease in subjective complaints continued in Group A, and both groups showed improvement in performance-based measures.
Conclusions
Patients with chronic stroke improved cognitive functioning after performing supervised home-based multi-domain computerized cognitive training.
