Insights

Acute disseminated encephalomyelitis (ADEM) in a teen was successfully treated with steroids after developing symptoms like double vision and weakness. Enterovirus infection was identified as a rare cause of this central nervous system demyelinating condition.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Pediatrics

Background:

  • Acute disseminated encephalomyelitis (ADEM) is a rare inflammatory demyelinating disease of the central nervous system (CNS).
  • It often occurs post-infection or post-vaccination, presenting with multifocal white matter lesions.
  • Early diagnosis and treatment are crucial for patient outcomes.

Observation:

  • A 16-year-old male with a history of attention-deficit/hyperactivity disorder (ADHD) presented with acute neurological deficits.
  • Symptoms included diplopia, right-sided hemiparesis, ataxia, and vomiting.
  • The patient had been on risperidone for 7 years.

Findings:

  • Clinical, laboratory, and cranial MRI confirmed a diagnosis of ADEM.
  • Cerebrospinal fluid (CSF) analysis revealed the presence of enterovirus.
  • The patient showed significant clinical improvement after pulsed methylprednisolone and subsequent prednisolone therapy.

Implications:

  • This case highlights a rare association between ADEM and enteroviral infection in an adolescent.
  • It underscores the importance of considering infectious etiologies in ADEM diagnosis.
  • Prompt steroid treatment can lead to substantial recovery in ADEM patients.

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...
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...
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...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Bacterial Meningitis II: Pathophysiology01:26

Bacterial 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...
