 Loss of psychic self-activation or apathy occurs frequently after damage to the superior medial prefrontal cortex. The current study investigated the effectiveness of a 2-year cognitive rehabilitation for the loss of psychic self-activation in a chronic stroke male patient with frontal lobe lesions. The patient received 4 therapeutic interventions consisting of 2 training tasks (target detection task and visual search task) designed to improve his spontaneous response to target stimuli. During the training, Go (Intervention 1, 3) and Go/No-go (Intervention 2, 4) tasks, involving pressing a response button (Intervention 1, 2) or pointing to targets on a screen (Intervention 3, 4) were used. Although there was no noticeable training effect with respect to reaction times, the patient's spontaneous response to the target stimuli (Intervention 1, 3) and his spontaneous selective response according to types of stimuli (Intervention 2) improved with repetitive practice of the training tasks. In addition, he also showed improvement in several tests of executive function and spatial attention, as well as daily life activities, after the cognitive rehabilitation.
