In an epidemiological study made by Seipelt et al. Recent studies have shown the presence of anti-thyroid antibodies in the CSF 5 enecfalopatia alpha-enolase antibodies in the serum of patients with Hashimoto’s encephalopathy, suggesting the involvement of an autoimmune mechanism in this condition 6.
The presence rapidly progressive dementia, ataxia, myoclonus, and especially the presence of triphasic complexes in the EEG, make the diagnosis a probable one for Creutzfeldt-Jakob disease. Diagnostic criteria are encephalopathy with elevated anti-thyroid antibodies in the absence of infection, tumour or alteration in the cerebral vascular system.
Hashimoto’s encephalitis HEencephalitis which responds to steroids and is associated with auto-immune thyroiditis, was described by Brain et al. Little is known about the pathogenesis.
Prion diseases are under compulsory notification in Brazil: Some symptoms may persist, such as tremors and loss of memory. Now, two years later, she is well and is on prednisolone 2.
