Nonfocal TNAs have long been considered benign. One study has shown, however, that patients who had suffered a prior nonfocal TNA were at higher risk of stroke and dementia, especially vascular dementia, than patients who did not have a history of prior TNA. [19]

Although more research is required, this study challenges the idea that nonfocal TNAs are benign events. Further workup should be considered in patients suffering nonfocal TNAs to elucidate the underlying cause of their transient symptoms and to achieve better risk stratification. [13, 19]
