INTRACEREBRAL HEMORRHAGE IN 2 PATIENTS WITH DOWNS-SYNDROME AND CEREBRAL AMYLOID ANGIOPATHY

Cerebral amyloid angiopathy (CAA) is an important cause of spontaneous intracerebral hemorrhages in the elderly and is often seen in the bra ins of patients with Alzheimer's disease, Down's syndrome (DS), and he reditary cerebral hemorrhage with amyloidosis of the Dutch type. We re port two patients with DS and extensive CAA who died of intracerebral hemorrhage; only two other such case reports exist in the literature. We believe the incidence of such cases is higher than is reported and that the likelihood of hemorrhage in the setting of CAA is independent of the patient's underlying disease.
