In the Netherlands an estimated 650.000 people live with the daily consequences of an Acquired Brain Injury (ABI). A substantial amount of these patients acquired their brain injury (traumatic brain injury, subarachnoid hemorrhage or cerebrovascular accident) at a relatively young age: between 18 and 50 years old. The chain-of-care for ABI aims for recovery in the subacute phase, usually within a period of one year after injury. After an adaptation period, the patients reach a new balance, with stabilization of complaints and reintegration, sometimes with the necessity of modifications. The group of patients who acquired a brain injury at a young age, have to face the effects of aging like decreased cognitive functions, which can cause the participation level to drop. This is called the ABI-effect in the current study. At this moment, insufficient information is available about the functioning of people who suffered ABI multiple years ago and have established a new balance, and now make the transition to an older phase of live.~Primary objective:~Explore the prevalence of the ABI-effect, by mapping the participation level.~Secondary objective:~Substantiate the occurence of the ABI-effect, by mapping cognitive functions of patients and compare these to healthy controls.~Tertiary objective:~Gain insight in the need of care for patients, to enhance regular care after ABI.
A prospective cohort study (questionnaires), with an embedded case control study (neuropsychological assessments) in which the data is gathered within a timeframe of 3 years. A group of 700 patients and a group of 100 healthy volunteers will be participating.
