ABSTRACT Examine frequency, character and course of symptoms until 3 months after MTBI and the relation between symptoms and disability.
Prospective cohort study of 122 consecutive patients with MTBI. Symptom assessment after 1, 7 and 14 days and 3 months post-injury by use of Rivermead Post-concussional Questionnaire. Disability assessment by use of Rivermead Head Injury Follow-up Questionnaire.
Patients reporting one or more symptoms declined from 86% on day 1 to 49% 3 months post-injury, when 25% also reported change in one or more domains of everyday activities. Poor memory, sleep disturbance and fatigue were most commonly reported. Symptom and disability scores were correlated (tau = 0.60; p < 0.001). Early symptom load correlated with late symptom load (tau = 0.38; p < 0.01).
Symptoms gradually decline post-injury. Symptoms correlate with disability at 3 months. Patients with early high symptom load are at risk for developing persisting complaints.

    ABSTRACT: Sleep quality affects all aspects of daily functioning and is vital for facilitating recovery from illness and injury. Sleep commonly becomes disrupted following moderate to severe brain injury, yet little is known about the prevalence of sleep disruption over time and how it impacts on recovery following mild injury.

    ABSTRACT: Post-traumatic brain injury symptoms, such as mental fatigue, have considerable negative impacts on quality-of-life. In the present study the effects of methylphenidate in two different dosages were assessed with regard to mental fatigue, pain and cognitive functions in persons who had suffered a traumatic brain injury. Fifty-one subjects were included and 44 completed the study. The treatment continued for 12 weeks, including three treatment periods with no medication for 4 weeks, administration of low dose methylphenidate (up to 5 mg × 3) for 4 weeks and normal dose methylphenidate (up to 20 mg × 3) for a further 4 weeks. The patients were randomized into three groups where all groups were given all treatments. Significantly reduced mental fatigue, assessed with the Mental Fatigue Scale (MFS) and increased information processing speed (coding, WAIS-III), were detected. The SF-36 vitality and social functioning scales were also improved significantly. Pain was not reduced by methylphenidate. The positive effects of treatment were dose-dependent, with the most prominent effects being at 60 mg methylphenidate/day spread over three doses. Observed side-effects were increased blood pressure and increased heart rate. Methylphenidate was generally well-tolerated and it improved long-lasting mental fatigue and processing speed after traumatic brain injury.

    ABSTRACT: Background/aimOccupational therapists work together with their medical and nursing colleagues to ensure that patients are able to return to safe and legal driving upon discharge from the emergency department after a range of illnesses and/or injuries. This study aimed to determine the type of information that is provided nationally in emergency departments to people after mild traumatic brain injury (mTBI), with respect to fitness-to-drive.Methods Cross-sectional electronic survey mailed to all emergency departments in Australia (N = 110). Responses were invited from medical, nursing, and allied-health professionals. The survey asked respondents to comment about the existence and use of fitness-to-drive management guidelines, as well as their opinion on when clearance should be given to return to driving post injury.Results104 clinicians completed the survey; the majority of respondents were medical staff (n = 46, 51%) followed by allied-health staff (n = 23, 25%), with the highest response rate provided from Victoria (n = 41, 45%). Just over one-third of respondents' emergency departments (n = 34, 36%) recommended a period of ‘no driving’ after mTBI, and within these departments, this recommendation was usually provided by medical staff (n = 25, 80%). Consensus was not displayed with respect to the safest time to return to driving after mTBI. Opinions from respondents strongly suggested that a review of fitness-to-drive management guidelines was required for mTBI patients (n = 78, 88%).Conclusion No consensus exists in the fitness-to-drive recommendations provided to patients after mTBI, and clinicians have reported the need for a review of fitness-to-drive management guidelines in Australian emergency departments. With their understanding about the complex interplay of the skills required for safe driving, occupational therapists are positioned to help guide the development of protocols in this area.
