Anti-NMDAR encephalitis is considered a multistage disease, characterized by nonspecific prodromal flu-like symptoms, followed by acute onset of psychiatric manifestations such as ...
What is the first line of immunotherapy?
Generally, first-line immunotherapies for this condition consist of high-dose steroids, IV immunoglobulin (IVIg), and plasma exchange (PE). Different institutions have utilized these treatments alone, in combination, or sequentially; as of yet, no data have confirmed the superiority of one approach over the others. Rituximab and cyclophosphamide are usually considered second-line treatments, and reserved for those patients who fail the first line.
Is Rituximab a second line treatment?
Rituximab and cyclophosphamide are usually considered second-line treatments, and reserved for those patients who fail the first line.
Can PE remove antibodies?
From an immunological perspective, the antibodies are synthesized both systemically and inside the brain so PE can remove them systemically but cannot alter the autoimmune process that is going on inside the brain. This is why up to 14% of patients do not have serum antibodies but do have positive CSF. 8.
Is NMDAR encephalitis a tumor?
Anti-NMDAR encephalitis can be associated with a tumor, especially ovarian teratomas in female patients older than 12 years. Brain MRI is normal in up to 67% of patients, whereas EEG is abnormal in 90% of patients. 3. EEG findings are nonspecific and can include slowing, disorganization of the background, and electrographic seizures.
What is the NMDA receptor?
Anti-N-methyl D-aspartate (NMDA) receptor (anti-NMDAR) encephali tis is among one of the most common autoimmune encephalitides. However, variations in clinical presentation and nonsequential multiphasic course often lead to delays in diagnosis. The mild encephalitis (ME) hypothesis suggests a pathogenetic mechanism of low-level neuroinflammation ...
What is anti N-methyl D-aspartate?
Anti-N-methyl D-aspartate (NMDA) receptor (anti-NMDAR) encephalitis, caused by immunoreactivity against the NMDA receptor 1 (NR1) subunit of the NMDA receptor, is one of the most common autoimmune encephalitides, first described in 2007 by Dalmau and colleagues in which psychiatric and neurologic symptoms were found in women with ovarian teratomas.1The condition was later confirmed to be not exclusively paraneoplastic. Later studies reported patients afflicted without tumor involvement.2,3Although available data suggest the disease is more prevalent in adult women, and in the non-Caucasian population, the condition has been described in both genders, in multiple races, and throughout the lifespan.4,5However, increasing case reports of anti-NMDAR encephalitis in the psychiatric literature have demonstrated the significant overlap between neurologic and psychiatric pathology associated with autoimmune encephalitis.6–10The clinical progression of the encephalitis has also been more thoroughly defined, with a multiphase model currently in use.11The prodromal phase is suggestive of a viral flu-like illness, in which fever, malaise, and fatigue may be prominent. This phase varies in duration and may also involve upper respiratory or gastrointestinal symptoms. The condition is often clinically recognized in the ensuing psychotic phase, in which delusions, hallucinations, paranoia, and agitation may be exhibited. During this phase, anti-NMDAR encephalitis is often misdiagnosed as a primary psychotic or substance-induced disorder. Following these psychotic symptoms is often the progression to a state in which catatonia, impaired attention, dyskinesias, and seizures may develop. In addition, significant autonomic instability, with wide-ranging fluctuations in body temperature, blood pressure, respiratory rate, and cardiac rhythm, may occur.12It is important to note that anti-NMDAR cases may not follow a strict phasic progression as mentioned earlier and may not include all of the symptomatology mentioned earlier, thereby complicating diagnosis.

During this phase, anti-NMDAR encephalitis is often misdiagnosed as a primary psychotic or substance-induced disorder.

What is the treatment for anti-NMDA receptor encephalitis?
Successful treatment of anti-NMDA receptor encephalitis with early teratoma removal and plasmapheresis
What is a positive serum CSF?
A positive serum or CSF sample screening for antibodies to the NMDAR subunit remains the gold standard in the diagnosis and must be performed in all patients with an acute onset of psychiatric symptoms with atypical features or unusual movements.
What is encephalitis in the CNS?
Encephalitis is an acute or chronic inflammatory disease of the central nervous system (CNS) where the presence of the neuronal surface antibodies can be demonstrated.[6] The present clinical case described a progression of anti-NMDAR encephalitis. This relatively unusual disorder has a typical chronological presentation: sudden onset with prodromal, fever-like symptoms, followed by a psychiatric disorder, decreased level of consciousness with focal and clonic seizures, dyskinesias, and autonomic instability.[7] In our clinical case, all of the cited symptoms were observed, so the clinical course of the anti-NMDAR encephalitis was typical. Furthermore, the patient was a young woman, which is also a common feature of this type of autoimmunological encephalitis. The female patient population represents around 80% of reported cases.[8] Additionally, the coexistence of an ovarian tumor, a teratoma in this case, is also typical for anti-NMDAR encephalitis.
What is NMDAR encephalitis?
Anti-N-methyl-D-aspartate-receptor (NMDAR) encephalitis is an autoimmune disorder with a wide spectrum of neuropsychiatric symptoms with a progressive clinical course and the possibility of effective management, which was first described in 2005 by Vitaliani et al.[1]
What hospital is Salamanca in?

Is anti-NMDAR antibody sensitive?
When anti-NMDAR is suspected the diagnostic tests contain detection of NMDAR autoantibodies in CSF and/or in the serum as the fundamental part of diagnosis, predominantly because other laboratory tests and imaging studies are not relevant.[9] According to some authors, CSF antibody testing is highly sensitive and specific for anti-NMDAR encephalitis and false positive and negative results may occur when testing only serum. [10]
Can serum be tested for anti-NMDAR?
There is currently some discussion as to whether serum or CSF must be tested for in the presence of anti-NMDAR antibodies. In the present case, high levels of anti-NMDAR antibodies were detected in the CSF, but not in the plasma. The association between the prodromal flu-like symptoms and the antibodies against NMDAR is also a material of debate. Some authors emphasize the connection between a viral infection and injury of the blood–brain barrier, which facilitates transmission of NMDAR autoantibodies to the CNS. [11]
