Abstract OBJECTIVE: This paper addresses the possible value of neurocognitive tests on the evaluation of patients before and after cranioplasty for large cranial defects. METHODS: In a single patient with a large corrected cranial defect a detailed neurocognitive analysis was performed utilizing the EXIT interview and Cognistat before and after surgery. Planning and development of the surgical prosthesis were based on the pre-operative reconstruction of the head CT and on pre-operative pictures of the patient. Xenon-CT anatomical and quantitative cerebral blood flow (CBF) analysis was performed before and periodically after cranioplasty. FINDINGS: A significant improvement in major cognitive functions was observed after surgery. INTERPRETATION: Cognistat is a detailed neuropsychological battery that permits a better assessment of patients in diverse neurological conditions. The EXIT interview gives a better rapid assessment of cognition not provided by other methods, such as the mini-mental status examination (MMSE). The utilization of these techniques permits a better understanding of long-term outcomes for patients with diverse neurological conditions, including post-cranioplasty patients.
