Affected patients present with seizures, stroke-like episodes, transient focal and global neurological deficits, and a variety of neuropsychiatric disturbance from dementia to hallucinations and psychosis. The encephalopathy evolves with concomitantly elevated anti-thyroid peroxidase antibodies, independent from hormonal thyroid function setting it apart from thyrotoxicosis and myxedema. A new patient reported with Hashimoto¡¯s encephalopathy, in whom neurocognitive impairment and stroke-like onset of hemiparesis and hemiparkinsonism correlated with brain magnetic resonance imaging fused with positron emission tomography. %K Autoimmune %K Encephalitis %K Hashimoto %K Thyroiditis %K Encephalopathy %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=78768
