Stroke-Like Episodes and Epilepsy in a Patient with COQ8A-Related Coenzyme Q10 Deficiency.

ABSTRACT

Coenzyme q10 (CoQ10) deficiency is an extremely uncommon disease that has very rarely been reported in adulthood. This case describes an elderly male with ataxia since adolescence, and visual disturbance since 40, presenting with recurrent episodes of seizures. Imaging revealed stroke-like episodes, with other immune and infective evaluations being negative. He was eventually diagnosed to have Primary CoQ10 deficiency secondary to CoQ8A mutation. This account highlights the challenges in diagnosing and managing primary Coenzyme Q10 deficiency, especially when it presents later in life with atypical features such as stroke-like episodes.
