Summary
This case report highlights a rare instance of refractory status epilepticus caused by tick-borne encephalitis (TBE) in an elderly patient. Early consideration of TBE is crucial for diagnosing encephalitis of unknown origin.
Area of Science:
- Neurology
- Infectious Diseases
- Virology
Background:
- Tick-borne encephalitis (TBE) is a viral infection affecting the central nervous system.
- Encephalitis of unknown origin can present with complex neurological symptoms.
- Refractory status epilepticus is a severe neurological emergency.
Purpose of the Study:
- To report a rare case of refractory status epilepticus secondary to TBE.
- To emphasize the importance of considering TBE in the differential diagnosis of encephalitis.
- To highlight diagnostic challenges in TBE cases.
Main Methods:
- Case report of a 78-year-old Japanese man.
- Initial presentation with hemiplegia and loss of consciousness.
- Diagnostic workup including tests for autoimmune encephalomyelitis and TBE viral antibodies.
Main Results:
- Patient initially diagnosed with autoimmune encephalomyelitis.
- Developed refractory status epilepticus despite corticosteroids and plasma exchange.
- Diagnosis of TBE confirmed by positive viral antibodies.
- Patient remained critically ill despite treatment.
Conclusions:
- TBE should be considered in the differential diagnosis of encephalitis of unknown origin, especially when associated with status epilepticus.
- Diagnostic delays can occur, necessitating broad differential considerations.
- This case underscores the potential severity of TBE and its varied clinical presentations.

01:24Epilepsy and Seizures: Overview
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

01:26Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
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...
01:19Encephalitis 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...
01:20Seizures l: Introduction
Understanding seizures and epilepsy relies on key definitions that help in recognizing, classifying, and managing these disorders. These definitions provide a framework for recognizing, classifying, and managing seizure disorders.DefinitionsA seizure is a sudden, abnormal burst of electrical activity in the brain that can cause changes in awareness, movement, sensation, or behavior, depending on the area involved. Epilepsy is a chronic condition characterized by recurrent, unprovoked seizures,...
