To the Editor Dr Biffi and colleagues1 observed that inadequate blood pressure (BP) control during follow-up was significantly associated with a higher risk of recurrence of lobar and nonlobar intracerebral hemorrhage (ICH). Higher risks were found in the lobar ICH group (more than 12% per year). This type of ICH is often related to cerebral amyloid angiopathy (CAA), which increases the risk of cerebral rebleeding, particularly in the first year after the event.2 For this reason, it would be interesting to investigate the pathogenetic characteristics of the patients with lobar ICH, evaluating the incidence of CAA.
