Summary
Bickerstaff brainstem encephalitis (BBE), an autoimmune neurological condition, can rapidly follow COVID-19 infection. Prompt recognition and treatment of BBE symptoms like impaired consciousness and ataxia after COVID-19 are crucial.
Area of Science:
- Neurology
- Infectious Diseases
- Autoimmune Disorders
Background:
- Bickerstaff brainstem encephalitis (BBE) is a rare autoimmune condition affecting the central nervous system.
- Key features include impaired consciousness, ophthalmoplegia, and ataxia.
- The association between BBE and preceding infections, including viral ones, is recognized.
Purpose of the Study:
- To report two cases of BBE occurring after COVID-19 infection.
- To highlight the temporal relationship between COVID-19 and the onset of BBE symptoms.
- To increase awareness of BBE as a potential neurological complication of COVID-19.
Main Methods:
- Case report of two patients diagnosed with BBE following confirmed COVID-19.
- Clinical presentation, diagnostic findings, and treatment outcomes were documented.
- Review of the temporal association between COVID-19 diagnosis and neurological symptom onset.
Main Results:
- Two patients presented with BBE symptoms including prolonged loss of consciousness, ophthalmoplegia, and ataxia/myoclonus within a week of COVID-19 diagnosis.
- Both patients showed improvement in consciousness following treatment with steroids, immunoglobulin, and/or plasmapheresis.
- The findings suggest a rapid onset of BBE post-COVID-19 infection.
Conclusions:
- BBE can manifest acutely following COVID-19.
- Central nervous system symptoms appearing rapidly after COVID-19 should prompt consideration of BBE.
- Early diagnosis and management are essential for improving patient outcomes.

Viral Meningitis
219
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...

Arboviral Encephalitis
70
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...

Bacterial Meningitis I: Introduction
32
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...

Encephalitis l: Introduction
29
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...

Encephalitis ll: Pathophysiology
32
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...

Brain Abscess l: Introduction
48
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial...
