Studies have shown that the most effective method of hemifacial spasm screening is MRI . In one study only 25 % of the CT scans showed the abnormality in hemifacial spasm patients, whilst more than half of the MRI imaging demonstrated a vascular anomaly.

He is currently involved in the care of patients requiring brain surgery, specifically for a variety of brain tumors ( gliomas and meningiomas, ) complex brain tumors ( skull base, acoustic, and pituitary tumors, ) cerebral aneurysms and arteriovenous malformations, trigeminal neuralgia, hemifacial spasm, and seizures.

Several families with hemifacial spasm have been reported, suggesting a genetic etiology or autosomal dominant pattern of inheritance in these families with low penetrance, and except for a younger age at onset, the clinical features overlap with the idiopathic cases . Evaluation of single-nucleotide polymorphisms in genes related to vascular change causing compression of blood vessles did not show an association with hemifacial spasm.
