    Insights

    This study describes two cases of recurrent acute demyelinization, highlighting the diagnostic challenges in differentiating acute disseminated encephalomyelitis from multiple sclerosis. Clinical and MRI findings suggest acute disseminated encephalomyelitis.

    Area of Science:

    • Neurology
    • Neuroimmunology
    • Radiology

    Background:

    • Acute demyelinization presents diagnostic challenges, particularly distinguishing between acute disseminated encephalomyelitis (ADEM) and multiple sclerosis (MS).
    • Recurrent courses in demyelinating diseases necessitate precise etiological differentiation for appropriate management.

    Observation:

    • Two cases of acute demyelinization with a recurrent clinical course were analyzed.
    • Key clinical features included significant memory and praxis impairments.
    • Magnetic resonance imaging (MRI) revealed large lesions predominantly in the subcortical white matter.

    Findings:

    • The observed clinical presentation, characterized by memory and praxis deficits, aligns with patterns seen in acute disseminated encephalomyelitis.
    • The presence of extensive subcortical white matter lesions on MRI further supports the diagnosis of acute disseminated encephalomyelitis over multiple sclerosis.
    • Recurrent episodes in this context suggest a potential atypical presentation or overlap in demyelinating pathologies.

    Implications:

    • Accurate differentiation between ADEM and MS is crucial for prognosis and therapeutic strategies.
    • Understanding atypical presentations of demyelinating diseases improves diagnostic accuracy.
    • This case series emphasizes the importance of integrating clinical and advanced imaging findings for diagnosing complex neurological disorders.

    Multiple Sclerosis l: Introduction01:19

    Multiple Sclerosis l: Introduction

    Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

    Encephalitis 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...

    Encephalitis 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...
    Arboviral Encephalitis01:25

    Arboviral 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...
    Viral Meningitis01:18

    Viral 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...
    Rocky Mountain Spotted Fever01:26

    Rocky 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.
