Insights

Acute disseminated encephalomyelitis (ADEM) in children typically presents after a febrile illness and involves neurological and psychological symptoms. Despite severe initial manifestations, most children achieve full recovery, though long-term follow-up is recommended.

Area of Science:

  • Pediatric Neurology
  • Neuroimmunology
  • Clinical Pediatrics

Background:

  • Acute disseminated encephalomyelitis (ADEM) is an immune-mediated demyelinating disease affecting the central nervous system.
  • ADEM in children presents with a diverse range of neurological and psychological symptoms following an infection or vaccination.

Purpose of the Study:

  • To elucidate the clinical characteristics and diagnostic features of acute disseminated encephalomyelitis (ADEM) in a pediatric cohort.
  • To evaluate the treatment response and long-term outcomes of children diagnosed with ADEM.

Main Methods:

  • Retrospective analysis of pediatric patients diagnosed with ADEM based on clinical presentation and MRI findings.
  • Treatment involved intravenous methylprednisolone followed by oral prednisolone.
  • Patients were monitored for up to three and a half years post-diagnosis.

Main Results:

  • The study included 14 children (79% female), aged 6 months to 12 years.
  • Neurological symptoms, including altered sensorium, cranial nerve palsies (most commonly facial nerve), and motor deficits, were prevalent.
  • Psychological manifestations such as aggressive behavior and psychotic symptoms were observed; all children achieved full recovery, with one developing multiphasic disseminated encephalomyelitis (MDEM).

Conclusions:

  • ADEM in children, despite significant neuropsychiatric involvement, generally shows a favorable immediate prognosis.
  • Long-term follow-up is crucial for identifying and managing potential cognitive impairments in pediatric ADEM survivors.

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 I: Introduction01:22

Bacterial 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...
