Abstract
BACKGROUND Hashimoto's encephalopathy, also known as steroid responsive encephalopathy, is associated with thyroid antibodies (SREAT) and is a rare but serious form of encephalopathy. In this paper, we describe the signs, symptoms, outcome, and treatments as noted in the case reports reviewed. METHODS We searched PubMed, Embase, and the Cochrane library for articles in which cases of Hashimoto's encephalopathy were described. The case description had to include the diagnosis, age, sex, presenting symptoms, and diagnostic tests. RESULTS We retrieved 360 articles and 65 fulfilled the inclusion criteria. These articles gave reports of 100 cases, with a mean age of 10.9 (range 2.8-19), 78 of whom were female. Epilepsy (79) - including epileptic state [24] - behavioural problems [36], hallucinations [21], headache [21], and decline in school performance [19] were most often reported. Antithyroid peroxidase (aTPO) was reported elevated in all patients. Most children [70] recovered fully, however 16 had late sequelae, mostly epilepsy. Therapies used include steroids, intravenous gammaglobulines, and cytostatics. CONCLUSIONS Epilepsy, behavioural problems, decline in school performance, and hallucinations are frequent symptoms of Hashimoto's encephalopathy. Steroids are the basis of treatment, although other immunomodulatory drugs seem to be successful. About one in ten children will experience late sequelae. In any child with unexplained neurological, psychiatric, or psychological dysfunction, serum anti-thyroidperoxidase (aTPO) should be determined.

Steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT): case report of reversible coma and status epilepticus in an adolescent patient and review of the literature. Eur J Pediatr 2014; 173:1263-73. [PMID: 25084973 DOI: 10.1007/s00431-014-2391-6] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2014] [Revised: 07/22/2014] [Accepted: 07/24/2014] [Indexed: 01/18/2023]
Abstract
UNLABELLED Steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT), also termed Hashimoto's encephalopathy (HE), is a rare immune-mediated disorder and is also affecting children and adolescents. It is characterized by altered mental status, seizures, and cognitive dysfunction. Therapeutic options include steroid treatment and prognosis range from complete recovery, a relapsing course to long-term cognitive sequelae. We describe a previously healthy 13-year-old girl presenting to the emergency room with coma and refractory status epilepticus. Generalized tonic-clonic seizures persisted after pre-hospital infusion of antiepileptic medication. She was found to have highly elevated levels of thyroid-stimulating hormone and anti-thyroid peroxidase antibodies not only in blood but also in cerebrospinal fluid while showing negative results for traumatic, infectious, metabolic, toxic, neoplastic, or other known specific autoimmune diseases. Cranial neuroimaging revealed no abnormality. A diagnosis of SREAT was established, and the patient improved rapidly on corticosteroids and levothyroxine therapy. However, 3 months after the discontinuation of steroid treatment, the girl relapsed. The current literature regarding SREAT is reviewed and summarized. CONCLUSION In children with SREAT, early diagnosis and treatment with corticosteroids is crucial and can lead to rapid clinical improvement. Clinicians should be aware of this uncommon but treatable condition, especially in female adolescents with unexplained seizures or an encephalopathic state.

Abstract
There is an increasing recognition of autoimmune limbic encephalopathy with the hope for earlier diagnosis and expedited and improved treatment. Although antibody testing remains the definitive clinical diagnostic feature, the presentation of a rapid dementia, behavioral changes, and seizures leads to investigation using cerebral imaging, electroencephalography, and cerebrospinal fluid to confirm the diagnosis and also to exclude similar disorders. The electroencephalographer may be asked to comment on the types of electroencephalography abnormality and provide input toward the diagnosis of limbic encephalopathy. This article reviews the literature on limbic paraneoplastic and nonparaneoplastic encephalopathies, providing descriptions and examples of the electroencephalography findings. Typically, there are patterns of slow theta and delta activity and different patterns of temporal and frontal epileptic activity.

Abstract
The authors present a case report and review the literature on Hashimoto encephalopathy. The onset of the disease may be marked by focal and then progressively generalized seizures or other neurological symptoms, but a cognitive decline or various psychiatric symptoms may also emerge. High levels of anti-thyroid peroxidase antibodies and/or anti-thyroglobulin antibodies are present in the serum. Corticosteroid treatment usually results in an improvement of symptoms. The syndrome is frequently overlooked and, therefore, the authors strongly recommend testing serum thyroid autoantibodies in cases with encephalopathy of unknown origin independently on the presence of thyroid disease in the patient or family history. The importance of long-term immunosuppressive treatment should also be stressed. Orv. Hetil., 2013, 154, 1312–1316.

Abstract
Acute disseminated encephalomyelitis is an immune-mediated inflammatory and demyelinating disorder of the central nervous system, commonly preceded by an infection. It principally involves the white matter tracts of the cerebral hemispheres, brainstem, optic nerves, and spinal cord. Acute disseminated encephalomyelitis mainly affects children. Clinically, patients present with multifocal neurologic abnormalities reflecting the widespread involvement in central nervous system. Cerebrospinal fluid may be normal or may show a mild pleocytosis with or without elevated protein levels. Magnetic resonance image (MRI) shows multiple demyelinating lesions. The diagnosis of acute disseminated encephalomyelitis requires both multifocal involvement and encephalopathy by consensus criteria. Acute disseminated encephalomyelitis typically has a monophasic course with a favorable prognosis. Multiphasic forms have been reported, resulting in diagnostic difficulties in distinguishing these cases from multiple sclerosis. In addition, many inflammatory disorders may have a similar presentation with frequent occurrence of encephalopathy and should be considered in the differential diagnosis of acute disseminated encephalomyelitis.

Abstract
Recently, several patients have been reported with various signs of encephalopathy and high thyroid antibody levels together with good responsiveness to glucocorticoid therapy. Despite the various clinical presentations, these cases have been termed "Hashimoto encephalopathy" (HE). Although all of the pathogenic components have not yet been clearly elucidated, it is believed that brain vasculitis and autoimmunity directed against common brain-thyroid antigens represent the most likely etiologic pathway. The most common clinical signs include unexplained or epilepsy-like seizures resistant to anti-convulsive treatment, confusion, headaches, hallucinations, stroke-like episodes, coma, impairment of cognitive function, behavioral and mood disturbance, focal neurological deficits, disturbance of consciousness, ataxia, and presenile dementia, together with the presence of high thyroid antibody levels, especially against thyroperoxidase (TPOab). In most cases, the thyroid function is normal or decreased; the thyroid function is rarely increased. The examination of the cerebrospinal fluid, EEG, MRI, SPECT, and neuropsychological examinations are primarily used as diagnostic tools. Most cases showed neural symptoms for months before the acute onset; in some cases, a dramatic acute onset was described. Once the diagnosis is made, corticosteroid treatment usually provides a dramatic recovery. The authors also present a short review of literary cases reported in last decade.

Abstract
Steroid-responsive encephalopathy with autoimmune thyroiditis is a relatively uncommon entity in the pediatric population. Although the pathogenesis of steroid-responsive encephalopathy with autoimmune thyroiditis is uncertain, an autoimmune mechanism is suspected to be the most likely cause. Seizures of unknown etiology are a common presenting sign in the pediatric intensive care unit, and steroid-responsive encephalopathy with autoimmune thyroiditis should be considered as a possible cause of recurrent seizures. The outcome of steroid-responsive encephalopathy with autoimmune thyroiditis is variable in children, and is partly dependent on early diagnosis and the administration of intravenous steroids. Only 31 pediatric cases of steroid-responsive encephalopathy with autoimmune thyroiditis were described in the English-language literature since 1966. Very few were reported in the United States or among males. We describe a 13-year-old boy presenting with a new onset of seizures as a manifestation of steroid-responsive encephalopathy with autoimmune thyroiditis. This report presents, to the best of our knowledge, the youngest male with steroid-responsive encephalopathy with autoimmune thyroiditis, and the only reported child with other autoimmune manifestations in addition to encephalopathy.

Abstract
BACKGROUND Hashimoto encephalopathy (HE) is a rare autoimmune disorder. It is defined as a 'corticosteroid-responsive encephalopathy associated with thyroiditis'. CLINICAL OBSERVATION We describe a boy who suffered from HE, responded only to intravenous immunoglobulin therapy. This is the first case report of immunoglobulin therapy in paediatric HE. CONCLUSION After review of the literature, we recommend that unexplained encephalopathy in children should lead to evaluation of thyroid autoantibody titres. Immunoglobulins should be considered.

Abstract
Adult-onset metachromatic leukodystrophy (MLD) often shows schizophrenia- or encephalopathy-like symptoms at an early stage, such as behavioural abnormalities, cognitive impairment, mood disorders and hallucinations. The authors report the case of an adult woman with MLD who had been given antipsychotic medication for schizophrenia. In the differential diagnosis, screening of auto-antibodies was important for ruling out other encephalopathies as she had a euthyroid Hashimoto thyroiditis. Diagnosis was based the results of MRI, nerve conduction velocity, sensory evoked potential, motor evoked potential, lysosomal enzyme activity and gene analysis studies. Brain MRI showed diffuse demyelination spreading from the deep white matter to subcortical area as high signals at the edges of these lesions in diffusion and apparent diffusion coefficient-map images with the U-fibres conserved. The authors diagnosed adult-onset MLD coexisting with euthyroid autoimmune Hashimoto thyroiditis.
