The aim is to 1) measure the frequency and extent of cognitive impairment after acute brain injury at six and 12-months after neuro-Intensive care unit (ICU) admission 2) explore the association between cognitive impairment at six and 12 months after ICU admission with the following potential risk factors: duration of ICU delirium (days), duration of sepsis (days), duration of post traumatic amnesia (days) and the severity of brain injury (initial Glasgow Coma Scale , 3) describe Health related quality of life, functional disability and frailty at six and 12 after ICU admission and 4) explore the association between the functional disability, frailty and health-related quality of life at 12 months after ICU admission
The study will provide information on cognitive impairment and Health related quality of life in patients surviving 12 months after acute brain injury, generate a hypothesis of useful variables to predict cognitive impairment or low levels of HRQoL, and potentially inform interventions for the prevention and treatment of cognitive impairment following neuro-ICU stay.
