Summary
Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis presents with varied neurological and psychiatric symptoms. This study details two distinct cases, highlighting the diverse clinical manifestations and progression patterns of this autoimmune disorder.
Area of Science:
- Neurology
- Immunology
- Neuroimmunology
Background:
- Autoimmune encephalitis is a condition where the body's immune system attacks the brain.
- Antibodies targeting the N-methyl-D-aspartate receptor (NMDAR) are a known cause of autoimmune encephalitis.
- NMDAR encephalitis typically presents with a range of neuropsychiatric symptoms, seizures, movement disorders, and autonomic dysfunction.
Observation:
- Two distinct cases of anti-NMDAR encephalitis were observed with different clinical presentations and disease progression.
- The first patient experienced status epilepticus, followed by psychosis, pyramidal signs, and diffuse encephalopathy.
- The second patient initially presented with acute psychosis, later developing seizures, dystonia, rigidity, oromandibular dyskinesias, and dysautonomia.
Findings:
- The cases illustrate the varied clinical spectrum of anti-NMDAR encephalitis.
- Different patterns of neurological and psychiatric symptoms can manifest in patients with this condition.
- The study discusses potential mechanisms underlying the observed clinical features, incorporating recent findings.
Implications:
- Understanding the diverse presentations of anti-NMDAR encephalitis is crucial for timely diagnosis and treatment.
- Further research into the pathogenic mechanisms can lead to improved therapeutic strategies.
- This work contributes to the broader knowledge of autoimmune neurological disorders and their management.

01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
