Neurovascular emergencies in the elderly

Neurovascular diseases are major causes of disability and death in the elderly; many present as medical emergencies. With the continuing growth of the geriatric population, there has been increasing interest in the impact of aging on the cerebrovascular system. Recent advances in the clinical neurosciences have demonstrated that neurovascular emergencies in the elderly often are amenable to treatment; neuroimaging plays a critical role in diagnosis and neurointerventional techniques are becoming increasingly important therapeutic options. This article provides an overview of some of the common neurovascular disorders in the elderly that require urgent evaluation and treatment, with an emphasis on the expanding role for interventional neuroradiology in their management.
