Presence of hyperekplexia (excessive startle response and hypertonia) 1
Myoclonic epilepsy 1
Congenital deafness 1
Macular dystrophy 1
Psychiatric disorders triggered by fever episodes 1
Normal mitochondrial DNA analysis and other routine laboratory investigations 1Management
No specific first-line treatments mentioned in the abstract 1
Adjunctive management may include anticonvulsants for seizure control (specific drug classes/doses not detailed) 1Special Populations
No specific information provided regarding pregnancy, pediatrics, elderly, or comorbidities 1Key Recommendations
Conduct comprehensive neurological and psychiatric evaluations including assessment for hyperekplexia and myoclonic seizures 1 (Evidence: Expert opinion)
Perform routine laboratory investigations including mitochondrial DNA analysis to rule out other causes 1 (Evidence: Expert opinion)
Consider multidisciplinary management involving neurology and psychiatry, especially in cases with psychiatric symptoms triggered by fever 1 (Evidence: Expert opinion)References
