↵* Behavioural change or prosopagnosia at presentation.
↵† Moderately severe.
↵‡ Modified questionnaire from which scaled score devised to range from 0 (no symptom distress) to 42 (maximum distress) and score >28=significant auditory hypersensitivity.
↵§ Both of these patients also reported hyperacusis.
↵¶ Standard tests of executive function (available for 33 of 43 patients) included the Weigl Card Sorting Test, the Wisconsin Card Sorting Test, the Trail Making Test Part B and the Stroop Task; best performance on any executive test is recorded.
