Combined early treatment in hemiplegic attacks related to CACNA1A encephalopathy with brain oedema: Blocking the...

Area of Science:

• Genetics and Neurology
• Molecular Medicine

Background:

• CACNA1A gene variants are associated with a spectrum of neurological disorders, including hemiplegic migraine and encephalopathies.
• Acute attacks in patients with CACNA1A variants can be severe, presenting with ataxia, hemiplegia, coma, and sometimes unilateral brain edema.
• Current management for these acute attacks is empiric, lacking established guidelines, and often unresponsive to standard antimigraine treatments.

Observation:

• A case study focused on an 11-year-old girl with CACNA1A-related encephalopathy experiencing acute attacks.
• The patient presented with headache, hemiconvulsions, hemiplegia, and coma during these attacks.
• Symptoms included migraine, seizure, fever, vomiting, and impaired consciousness, accompanied by hemispheric slowing on EEG.

Findings:

• A personalized emergency treatment protocol was implemented.
• The protocol involved combined corticosteroid pulses and hypertonic solution administration.
• This combined treatment led to a reduction in the severity and duration of acute attacks.

Implications:

• Early administration of corticosteroids and hypertonic solutions may be beneficial for managing acute attacks in CACNA1A-related encephalopathy.
• This personalized approach offers a potential therapeutic strategy for severe neurological episodes linked to CACNA1A variants.
• Further research is warranted to establish evidence-based guidelines for managing these rare neurological conditions.
