Practitioner-Guided Note
When treating MELAS, strictly avoid valproic acid and minimize statin use due to mitochondrial toxicity. For Moyamoya, prioritize surgical bypass to restore perfusion and reduce stroke risk. When evaluating incidental intracranial aneurysms, look for high-risk indicators like posterior circulation location, coexisting polycystic kidney disease, or a history of smoking and hypertension to guide intervention.
Key Takeaways
MELAS is a maternally inherited mitochondrial disorder requiring metabolic support.
Valproic acid must be avoided in patients diagnosed with MELAS.
Moyamoya syndrome is linked to underlying conditions, unlike idiopathic Moyamoya disease.
Most rupturing intracranial aneurysms are small, measuring under ten millimeters.
Aneurysms located in the posterior circulation carry a significantly higher rupture risk.
