Moyamoya disease (MMD) is an incompletely understood malady that affects many age
groups, primarily in a bimodal age distribution. We present a patient with the association
of type 1 diabetes mellitus (type 1 DM) and MMD followed by a review of the existing
literature. We found five papers that describe this association, in the form of one
case report, one case series, and three retrospective reviews. Despite a poor understanding
of the underlying pathophysiology, a clear association between autoimmune conditions
and MMD appears to exist. Clinicians who manage such patients ought to be vigilant
and have a high index of suspicion when young patients with type 1 DM present with
new onset of neurological symptoms.
