Rapidly progressive dementia and parkinsonism associated to multiple dural arteriovenous fistulas

Abstract:

Introduction. Rapidly progressive dementias are an infrequent group of diseases characterised by cognitive deterioration and other neurological disorders that develop over a period ranging from weeks to months. Their causation is varied and includes a large number of neurodegenerative, toxic, metabolic, autoimmune, infectious and vascular conditions. Case report. We report the case of a 69-year-old male who was admitted to hospital due to a rapidly progressive dementia and parkinsonism caused by multiple dural arteriovenous fistulas, which were successfully treated by means of endovascular therapy. Conclusion. Dural arteriovenous fistulas are anomalous connections between the dural arteries and the venous sinuses or cortical veins that are an unusual cause of rapidly progressive dementia. They must, however, be taken into account, given the availability of a specific treatment with reversal of the symptoms.
