Abstract:
Acute disseminated encephalomyelitis(ADEM) is an uncommon inflammatory demyelinating disease involving central nervous system white matter. A series of seven cases seen over a period of one year have been described. The patients presented with acute onset of focal neurological deficit (3 patients), alteration of sensorium(3) and ataxia(1). CT scan showed non specific hypodensity in 4 cases and was normal in 3 patients . MRI showed characteristic radiological changes. Complete recovery was seen in 3 patients , one died and 3 were left with sequelae.
Insights
Acute disseminated encephalomyelitis (ADEM) is a rare central nervous system inflammatory disease. This study describes seven cases, highlighting varied presentations and outcomes, with MRI proving crucial for diagnosis.
Area of Science:
- Neurology
- Neuroimmunology
- Radiology
Background:
- Acute disseminated encephalomyelitis (ADEM) is an uncommon inflammatory demyelinating disease.
- It primarily affects the central nervous system's white matter.
Purpose of the Study:
- To describe a series of seven cases of ADEM observed over one year.
- To analyze the clinical presentations, radiological findings, and patient outcomes.
Main Methods:
- Retrospective case series of seven patients diagnosed with ADEM.
- Clinical data collection including neurological deficits and sensorium alterations.
- Radiological assessment using CT and MRI scans.
Main Results:
- Patients presented with acute onset focal neurological deficits, altered sensorium, or ataxia.
- CT scans showed non-specific hypodensities or were normal.
- MRI revealed characteristic radiological changes indicative of ADEM.
- Outcomes included complete recovery (3 patients), death (1 patient), and sequelae (3 patients).
Conclusions:
- ADEM presents with diverse neurological symptoms.
- MRI is essential for diagnosing ADEM, often showing characteristic changes.
- Patient outcomes vary significantly, with a notable proportion experiencing sequelae or mortality.
