Intact theory of mind in TBI with behavioural disturbance.
Behavioural disturbance following TBI is common. Theory of mind(ToM) deficits have been noted in autism where difficulties with social interaction and communication are evident. It was hypothesised that TBI patients with behavioural disturbance would show deficits on ToM tasks independent of executive function. Twenty TBI patients with behavioural disturbance and 20 TBI patients without were assessed on verbal (stories) and non-verbal (cartoons) ToM tasks,standard psychometry, and measures of executive function.TBI patients were unimpaired on the ToM tasks. Both groups were unimpaired on standard tests of executive function (verbal fluency and trail making test) but were impaired on the Behavioural Assessment of Dysexecutive Syndrome (BADS). Groups did not differ significantly on these tests. It is concluded that ToM ability does not predict behavioural disturbance and may be independent of executive functioning.
