Neuropsychiatric Outcomes and Disrupted Sleep Following Acquired Brain Injury

The two most common causes of brain injury are stroke and trauma. Both sleep and mental health problems are common after brain injury; we will investigate whether there is a relationship between poor sleep quality and worse mental health in this group. We will also follow patients up, at approximately three-monthly intervals until one year after injury, to see how sleep and mental health symptoms change over time and with recovery. We will assess sleep in detail using questionnaires, a sleep monitor worn on the wrist, a portable brain activity sensor, and a sleep mat. We will assess mental health (neuropsychiatric) symptoms using questionnaires. Participants will be asked to complete these assessments at baseline and at approximately 3-monthly intervals until they reach 12 months post-injury. This data will allow us to explore the types of sleep disruption seen after brain injury and examine the association between sleep and mental health symptoms.
