The documented historical research for rasmussens encephalitis

There are at least 20 distinct receptors for glutamate in the brain, one of which is denoted GluR3. It is open to discussion how the dichotomy of type 1 patients children and type 2 patients adolescents and adults can be explained. Neuronal cell density appeared to be reduced, particularly in chronic cases.

It seemed to resemble a viral infection, but despite much research, no organism could be consistently found in the brains of those who had suffered from the disorder. It had a median duration of 7.

In our experience, the three stages are clinically reliably distinguishable as follows, even under retrospective conditions: Specifically, the body responds to one of the glutamate receptors, GluR3, as if it were an invading organism.

Rasmussen's encephalitis Definition Rasmussen's encephalitis, also termed Rasmussen's syndrome, is a rare degenerative brain disease that initially affects only one side of the brain.

The older the patient is when the surgery is performed, however, the more likely they are to suffer permanent sensory, speech, and motor losses. The prodromal phase was omitted or was short median 0 months, range 0—7 months. The clinical parameters seizure frequency and hemiparesis have previously been used for a depiction of the natural history of RE Oguni et al.


To account for these differences, a distinction between type 1 and type 2 patients is suggested. An EEG will usually show the electrical features of epilepsy and slowing of brain activity in the affected hemisphere, and MRI brain scans will show gradual shrinkage of the affected hemisphere with signs of inflammation or scarring.

The medical literature does not describe a higher incidence of this disease in either gender or in any particular racial group or geographical area. In two patients 03 and 10however, EPC recurred after a period of remission with fixed neurological deficit, and led to surgical treatment.

They had been healthy until the disease became manifest by the first epileptic seizure. RE was initially described as a condition affecting children Rasmussen et al. Quantitative analysis To assess the volume of the affected hemisphere in relation to the unaffected one, the following procedure was performed on T1 scans if no T1 scan was available, FLAIR images were used, or, if no FLAIR images were available, T2 images were used.

Results Clinical, neuroradiological and neuropathological data of the patients are summarized in Table 1. However, the treatment of choice remained hemispherectomy, surgical removal of the affected half of the brain.

There are lesions with local brain swelling in the right parietal and occipital lobes and right cerebellar hemisphere.


From the axial slices, the one that showed the third ventricle at its largest extent was selected. Rasmussen’s encephalitis (RE) is a rare neurological disorder of inflammatory aetiology characterised by encephalitis, intractable seizures, hemiparesis, variable motor deficits, and dementia. It is not commonly considered in the clinical differential diagnosis of a patient with a past history of a stroke-like episode presenting with status epilepticus.

Rasmussen's encephalitis, also termed Rasmussen's syndrome, is a rare degenerative brain disease that initially affects only one side of the brain. It first manifests in childhood with the onset of epileptic seizures.

Abstract. Rasmussen’s encephalitis (RE) is a chronic inflammatory disease of unknown origin, usually affecting one brain hemisphere. In the present study, a comprehensive assessment of the natural history of the disorder is presented. Rasmussen encephalitis (RE), also called Rasmussen syndrome, is a rare, progressive, chronic encephalitis (inflammation of the brain) affecting one hemisphere (one side) of the brain.

It occurs mainly in children (most cases are seen in six to seven-years-old children). Because none of the autoantibodies have been found in more than a small number of patients with Rasmussen's encephalitis, and responses to plasma exchange are unpredictable, the role of CNS autoantibodies in the pathogenesis of Rasmussen's encephalitis is still unclear.
