Summary
Acute leukoencephalopathy with restricted diffusion is a significant cause of childhood encephalopathy, often leading to prolonged illness and lasting neurological issues like cognitive impairment and epilepsy.
Area of Science:
- Pediatric Neurology
- Neuroimaging
- Infectious Diseases
Background:
- Acute leukoencephalopathy with restricted diffusion (ALERD) is an emerging neurological condition in children.
- Understanding its clinical and radiological features is crucial for diagnosis and management.
Purpose of the Study:
- To investigate the clinico-radiological profile of pediatric ALERD.
- To analyze the outcomes and sequelae in affected children.
Main Methods:
- Retrospective chart review of 16 children diagnosed with ALERD between July 2015 and July 2018.
- Analysis of clinical data, neuroimaging findings (MRI), and modified Rankin Scores.
Main Results:
- The study included 16 children (mean age 4.4 years) with ALERD, predominantly presenting with fever, seizures, and altered sensorium.
- MRI revealed diffusion restriction in all cases, with varied symmetry.
- Significant sequelae included post-encephalopathic epilepsy (43.7%), behavioral problems (62.5%), speech issues (50%), and cognitive delay (18.8%).
Conclusions:
- ALERD is an important cause of acute encephalopathy in children, characterized by a protracted course.
- Long-term sequelae such as cognitive impairment and refractory epilepsy are common, necessitating further research and management strategies.

01:19Encephalitis 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...
01:26Encephalitis 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...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
