Dementia and parkinsonism are rarely observed in dural arteriovenous fistula. Here, we report a case of a 63‐year‐old man with recurrent dural arteriovenous fistula, who developed progressive dementia and parkinsonism as a result of a dural arteriovenous fistula at the torcular herophili. A sinus thrombosis induced the abnormal cortical venous reflux from the isolated straight sinus, resulting in the deep venous congestion of the thalamus and basal ganglia, which led to dementia and parkinsonism. However, the third endovascular embolization ameliorated memory disturbance and apathy with a slight improvement of parkinsonism. Although recoveries from dural arteriovenous fistula‐associated neurological deficits are variable depending on the severity, duration and, furthermore, selective vulnerability of the responsible ischemic lesions, early treatment should be essential for better recovery.
