    On the 26th of April, local Oregon news station, KMTR interviewed husband and wife, Tim and Kelly McCabe. Kelly is battling a rare autoimmune disease known as Hashimoto’s Encephalopathy (also know as Steroid Responsive Autoimmune Encephalopathy Associated with Thyroiditis or SREAT). Recently a member of the online support group, Understanding Hashimoto’s Encephalopathy – A Support Forum, Tabitha Andrews-Orth, meet up with Kelly for the first time in person.

  • Link: Autoantibodies to neuronal surface antigens in thyroid antibody-positive and -negative limbic encephalitis
    Background : Thyroid antibodies (Thy-Abs) are frequently detected in various autoimmune disorders in coexistence with other systemic autoantibodies. In association with an encephalopathy, they are often taken as evidence of Hashimoto’s encephalitis (HE). However, the presence of Thy-Abs in a cohort of limbic encephalitis (LE) patients and their association with anti-neuronal autoimmunity has not been […]

  • Link: Hashimoto's encephalopathy: Report of three cases
    Both severe thyrotoxicosis and hypothyroidism may affect brain function and cause a change in consciousness, as seen with a thyroid storm or myxedema coma. However, encephalopathy may also develop in patients with autoimmune thyroid diseases independent of actual thyroid function level, and this is known as Hashimoto’s encephalopathy. Although most patients are found to have […]
  • Link: Hashimoto's Encephalopathy Update
    First described in 1966, Hashimoto’s encephalopathy (HE) is still considered a controversial disorder, likely under-recognized, with diagnosis primarily based on exclusion. That is, if no other causes for the neurological symptoms are found and high titers of thyroid antibodies are present, a diagnosis of HE is made.   This article comes from the blog The […]
  • Link: Cognitive and affective dysfunctions in autoimmune thyroiditis
    Hashimoto’s thyroiditis (HT) is the most frequent cause of hypothyroidism in areas with sufficient iodine intake. While the impact of thyroid function on mood and cognition is well known, only in the recent years, an increasing number of studies report on the association of HT with cognitive and affective disturbances also in the euthyroid state. […]
  • Link: Hashimoto’s encephalopathy: A frequently missed diagnosis
    Hashimoto’s encephalopathy is described as a syndrome of encephalopathy and high serum antithyroid antibodies that is responsive to glucocorticoid therapy. We report a patient with overt hypothyroidism who presented with stroke-like episodes and a status epilepticus which responded dramatically to intraveous methylprednisolone given for a severe bronchospasm following aspiration. The high antithyroid antibody titers and […]
  • Link: The use of plasma exchange in Hashimoto's encephalopathy: A case report and review of the literature.
    Hashimoto’s Encephalopathy (HE) is a very rare condition characterized by psychosis, seizures, cognitive fluctuations, and myoclonus. In a few published cases, plasma exchange has been used due to the theoretical removal of antithyroid peroxidase antibodies (anti-TPO), one of the postulated causes of the condition.   The abstract can be found at unboundmedicine.com; however, the full […]

    Dear Editor, Cornelia de Lange syndrome (CdLs) is a rare genetic disease diagnosed as a cluster of symptoms; however, there are only a few reports mentioning the immunologic problems in patients with CdLs. Hashimoto’s encephalopathy (HE) is an autoimmune encephalitis, which manifests as neurocognitive impairment and elevated antithyroid antibody (ATA) titers. Childhood HE manifests especially […]
  • Link: Hashimoto's Encephalopathy - A Brief Review
    Hashimoto’s encephalopathy (HE) is a syndrome of altered mental status, hallucinations, delusional thinking, and often, epileptic seizures. It is diagnosed by the clinical syndrome, the presence of elevated titers of antithyroid antibodies, the lack of another diagnosis based on clinical evaluation, and the response to corticosteroid and other immunosuppressant treatment. This review discusses the symptoms, […]
  • Link: Hashimoto’s encephalopathy mimicking presenile dementia
    Abstract Hashimoto’s encephalopathy (HE), which carries kaleidoscopic clinical presentations, is easily misdiagnosed in clinical practice. Early diagnosis and prompt initiation of steroid therapy are associated with good prognosis. We describe a 50-year-old female patient who had subclinical hypothyroidism and who presented herself with gradual cognitive impairment, accompanied with auditory hallucination and delusion. Increased anti-thyroid antibodies […]

    Autoimmune Encephalitis may be triggered by infection in which case the term “Post-infectious Encephalitis” is used. ADEM( Acute Disseminated Encephalomyelitis ) is a Post-infectious Encephalitis. The illness usually follows in the wake of a mild viral infection (such as those that cause rashes in childhood) or immunisations. Typically there is a delay of days to two […]
  • Link: Antithyroid antibodies in the CSF: Their role in the pathogenesis of Hashimoto’s encephalopathy
     Abstract Antithyroid antibodies and circulating immune complexes (CIC) were found in the CSF of six patients with Hashimoto’s encephalopathy (HE) but not in the CSF of 21 controls. The synthesis of autoantibodies and CIC was intrathecal and their titers were independent of the patients’ clinical status or therapy. Their presence in the CSF of patients […]
  • Link: Complex partial status epilepticus as a manifestation of Hashimoto's encephalopathy
    Epileptic seizures are a frequent manifestation of Hashimoto’s encephalopathy. However, status epilepticus associated with Hashimoto’s encephalopathy are not well characterized in medical literature. We described here a 16-year-old girl who presented with complex partial status epilepticus associated with elevated anti-thyroid antibodies. Ictal EEG showed lateralized high amplitude rhythmic delta waves over the right hemisphere and […]

  • Link: Hashimoto's Encephalopathy Complicated by Cerebellar Ataxia: A Case Report

    To present a case of Hashimoto’s Encephalopathy (HE) with long-term neurological sequelae.BACKGROUND: Hashimoto’s Encephalopathy, also known as steroid responsive encephalopathy secondary to autoimmune thyroiditis (SREAT), is a rare condition that typically affects middle aged females with known anti-TPO antibodies and a history of Hashimoto’s thyroiditis. The diagnosis is often overlooked because there is no diagnostic biomarker, and patients can present with several non-specific neurological symptoms that are often incorrectly attributed to other disease processes. Neurological outcomes are rarely reported. It is important to recognize and distinguish HE from other encephalopathies as it is a distinct, treatable entity, which is almost always responsive to steroid therapy.

    Hashimoto’s encephalopathy (HE) is a rare neuropsychiatric syndrome associated with antithyroid antibodies. It may have an acute onset (episodes of cerebral ischemia, seizure, and psychosis) or it may present as an indolent form (depression, cognitive decline, myoclonus, tremors, and fluctuations in level of consciousness). We here describe a case of encephalopathy presenting as non-convulsive status epilepticus associated with Hashimoto’s thyroiditis (HT), unresponsive to corticosteroid therapy, with improvement after plasma exchange treatment.

    Abstract: Hashimoto’s encephalopathy (HE) is a poorly understood and often misdiagnosed rare autoimmune disease with varied neurological and psychiatric features. The low prevalence and varied clinical features coupled with unclear pathogenesis and histopathologic characteristics have caused still doubts in any particular diagnostic criteria. Therefore, more case studies are needed to characterize the clinical, laboratory and […]
