Truncal Instability and Titubation in Patients With Acute Encephalopathy With Reduced Subcortical Diffusion

Area of Science:

• Neurology
• Pediatric Neurology
• Neuroscience

Background:

• Acute encephalopathy with reduced subcortical diffusion (AED) is a critical neurological condition.
• Understanding post-seizure clinical manifestations is crucial for prognosis and management.

Purpose of the Study:

• To investigate truncal instability and titubation following seizures in pediatric patients with AED.
• To correlate these clinical signs with disease severity and specific brain lesions.

Main Methods:

• Retrospective study of 15 pediatric patients diagnosed with AED.
• Analysis of clinical data including seizure duration, GCS scores, Tada score, and biochemical markers.
• Correlation of truncal instability and titubation with lesion location, particularly in frontal lobes.

Main Results:

• Six patients exhibited moderate-to-severe truncal instability after the first seizure, associated with longer seizure duration, lower GCS, higher Tada score, and elevated creatinine and glucose levels.
• Three patients with bilateral frontal lobe lesions showed truncal titubation, a previously unreported feature in AED.
• Truncal instability correlated with disease severity, while titubation suggested specific frontal lobe involvement.

Conclusions:

• Truncal instability in sitting position after the first seizure may reflect AED severity.
• Truncal titubation could be an indicator of bilateral frontal lobe lesions in AED patients, especially those without severe instability.
• Further research using objective methods like stabilometry is needed to confirm the association between frontal lobe lesions and truncal titubation in AED.
