The long-term outcome of persons with impaired consciousness after brain injury remains relatively unclear. The first 12 months post ictus are widely reported as the period of greatest change, with an estimated 20% of persons with traumatic brain injury recovering consciousness. However, beyond 12 months post traumatic and 6 months post-nontraumatic injury the chances of further recovery are thought to diminish significantly. The aim of this study was to investigate the behavioural and psychosocial outcome of 12 patients with impaired consciousness 2 years post ictus. At the time of recruitment five of these patients met the diagnostic criteria defining the vegetative state and seven of these patients met the diagnostic criteria defining the minimally conscious state. Patients were assessed using the Wessex Head Injury Matrix at recruitment and again at least 2 years after initial contact. Functional and psychosocial outcome were also explored. Most patients showed some improvements to their behavioural portfolio, but all were still very dependent physically and all required a high level of support in their activities of daily living. None of the patients had emerged from their original condition, despite exhibiting larger behavioural portfolios. The implications of these findings for the management of patients in low awareness states are discussed.
