A 70-year-old man, a urinary retention of unknown origin from 10 years ago, decreased cognitive function from 4 years ago, vision impairment advanced a year ago. Brain MRI with DWI showed high intensity erea in the corticomedullary junction. We diagnosed as intranuclear inclusion body disease (NIID) because of p62-positive intranuclear inclusion bodies by skin biopsy. Electroretinogram revealed amplitude reduction in the cone response superiority. Nerve conduction test showed mild conduction velocity reduction. Furthermore, in the somatosensory evoked potential of the lower limb, latency of the first cortical component was prolonged. These electrophysiological abnormalities were considered to be associated with the pathological features of NIID.
