Patients with Hashimoto encephalitis may present with seizures, stroke-like episodes, transient focal and global neurological deficits, and a variety of neuropsychiatric disturbances. The encephalopathy evolves with elevated anti-thyroid peroxidase antibodies, independent of hormonal thyroid function. A teenager experienced repeated concussions antedating onset of Hashimoto encephalopathy. Neuroradiological studies showed overlapping areas of altered brain metabolism and vascular perfusion in the hippocampus, deemed most vulnerable in autoimmune encephalopathy. Concussive brain injury may be a contributing factor in the development of encephalopathy due to its capacity to alter the blood-brain barrier.
