Principal factors associated with the risk of recurrence of intracranial hemorrhage (ICH).

Factor	Lower risk of recurrence	Higher risk of recurrence
Type of ICH	Subdural ICH, Epidural ICH	Subarachnoid ICH, Lobar ICH
Cause of ICH	Traumatic	Spontaneous
Size of ICH	Mild (i.e. volume)< 30 ml	Moderate to severe
Presence of cerebral microbleedings	No	Yes
Amyloid angiopathy	No	Yes

ICH: intracranial hemorrhage.

Etiology, location, and imaging features of ICH are important factors in predicting the risk of recurrence Spontaneous bleedings are more likely to recur than traumatic ones, especially if cerebral microbleeds are shown by imaging. Indeed, in patients with a traumatic ICH, the restarting of OACs is likely to be related to a lower incidence of ischemic stroke and mortality rate (83). Notably, in these subjects, a higher recurrence of ICH has also not been reported (83). On the contrary, a relationship between anticoagulation strategy and recurrent ICH has been described in patients with AF after a non-traumatic ICH. Remarkably, the cerebral microbleeds (CMBs) neuroimaging finding is likely to be more strictly associated with a greater recurrence of ICH (84).
