Compared to patients with IS/TIA, patients with conversion disorder were more likely to be female (P=0.0006) and younger (P<0.0001); were less likely to have diabetes mellitus (P=0.0252), hypertension (P=0.0004), or atrial fibrillation (P<0.0001); were less likely to receive tissue plasminogen activator (P<0.0001); and had a shorter median consultation duration (P=0.0175). This evidence concerns the gene PLAT and transient ischemic attack.
