Insights

This study presents a case of a 17-year-old boy with acute disseminated encephalomyelitis (ADEM) and peripheral neuropathy. Combined treatment with intravenous immunoglobulin and high-dose methylprednisolone showed significant improvement in neurological symptoms.

Area of Science:

  • Neurology
  • Immunology
  • Pediatrics

Background:

  • Acute disseminated encephalomyelitis (ADEM) is a rare, immune-mediated inflammatory demyelinating disease of the central nervous system.
  • Peripheral neuropathy can sometimes co-occur with ADEM, presenting complex diagnostic and therapeutic challenges.

Observation:

  • A 17-year-old male presented with fever, headache, and neck stiffness, progressing to paraplegia, urinary retention, and cranial nerve palsies.
  • Cerebrospinal fluid analysis revealed elevated protein and mononuclear cells.
  • Brain and spinal cord MRI showed demyelinating lesions consistent with ADEM, while nerve conduction studies indicated peripheral neuropathy.

Findings:

  • Initial treatment with high-dose methylprednisolone alone did not prevent neurological deterioration, including respiratory failure.
  • Combination therapy with intravenous immunoglobulin and high-dose methylprednisolone led to rapid clinical improvement within one week.
  • The patient showed recovery from respiratory failure and upper limb weakness, with gradual improvement in lower limb function over 18 months.

Implications:

  • Combined ADEM and peripheral neuropathy is a treatable neurological condition.
  • Intravenous immunoglobulin combined with high-dose methylprednisolone may be an effective therapeutic strategy for this combined presentation.
  • Early recognition and aggressive multimodal treatment are crucial for optimizing outcomes in patients with severe ADEM and coexisting peripheral neuropathy.

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...
Encephalitis l: Introduction01:19

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...
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...
Diphtheria01:28

Diphtheria

Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...

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...

Diabetic Neuropathy

DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
