Mental fatigue is a complex hidden disability. This study investigates how people with mental fatigue assess the accessibility of various typical city environments. Specifically if they use spatial strategies to redress their disability and how they view interaction with other actors in the same space. The study also aims to offer tools for city planners in order to facilitate an understanding of how infrastructure can promote accessibility in public buildings and spaces. The study at hand is qualitative and was conducted as a virtual city tour which allowed the subjects to share their experience of accessibility. Labov's theory of narrative structure was used to analyse the data. The samples of narrative were collected from people who suffer from mental fatigue after a mild traumatic brain injury. The results show that stimuli intense environments increase the use of spatial strategies and complicate the accessibility as well as the interaction with others. The study finds that people with mental fatigue should fall under the protection of the availability impact act and therefore have a legal right to accessibility promoting actions.
