BACKGROUND There is growing evidence supporting the role of inflammation in aneurysmal subarachnoid hemorrhage (aSAH) pathophysiology and it is of great interest to elucidate which immune mechanisms are involved. METHODS 12 aSAH patients and 28 healthy controls were enrolled prospectively. We assessed leukocytes subpopulations and their activation status by flow cytometry in cerebrospinal flu...

BACKGROUND The pathogenesis of development and rupture of intracranial aneurysms (IA) is largely unknown. Also, screening for IA to prevent aneurysmal subarachnoid hemorrhage (aSAH) is inefficient, as disease markers are lacking. We investigated gene expression profiles in blood of previous aSAH patients, who are still at risk for future IA, aiming to gain insight into the pathogenesis of IA an...

Aneurysmal subarachnoid hemorrhage (aSAH) remains a morbid and lethal condition. Despite an increase in the number of unruptured intracranial aneurysms treated with endovascular techniques or microsurgical clipping, the incidence of aSAH is relatively unchanged in many countries including the United States. It seems as if risk factor modification such as smoking cessation has more impact on pre...

OBJECTIVE Among good outcome survivors of aneurysmal subarachnoid hemorrhage (aSAH), only 23% have normal neurocognitive performance, despite imaging that is often normal. The aim of this work is to explore the use of magnetoencephalography (MEG) after endovascular treatment of ruptured aneurysms. METHODS Good outcome aSAH patients treated with coiling and matched controls were recruited. Cli...

OBJECTIVE Recent studies suggest that the Montreal Cognitive Assessment (MoCA) is more sensitive to stroke-associated cognitive dysfunction than the Mini-Mental State Examination (MMSE), but little is known about how these screening measures relate to neurocognitive test performance or real-world functioning in patients with good recovery after aneurysmal subarachnoid hemorrhage (aSAH). The aim...

Acute aneurysmal subarachnoid hemorrhage (aSAH) is a critical systemic condition, and survivors of the primary bleed require multidisciplinary neurointensive care. People who survive aSAH carry an increased risk for various complications including epilepsy, depression, cognitive impairment, shunt requirement for hydrocephalus, and shunt complications. Hydrocephalus after aSAH has been reported ...

The discovery of tissue plasminogen activator to treat acute stroke is a success story of research on preventing brain injury following transient cerebral ischemia (TGI). That this discovery depended upon development of embolic animal model reiterates that proper stroke modeling is the key to develop new treatments. In contrast to TGI, despite extensive research, prevention or treatment of brai...

BACKGROUND AND PURPOSE There is high case-fatality rate and loss of productive life-years related to aneurysmal subarachnoid hemorrhage (aSAH) but data on long-term survival of patients with aSAH are scarce. We aim to evaluate long-term excess mortality and related risk factors after an aSAH event. METHODS Survivors (n=3078) of aSAH who had survived for ≥1 year were reviewed for this retrospe...

INTRODUCTION Neuroendocrine deficiencies may affect recovery after aneurysmal subarachnoid hemorrhage (aSAH). Insulin like growth factor-I (IGF-I) regulates neuronal growth and apoptosis in ischemic stroke. Our study was designed to a) characterize the behavior of serum IGF-I and growth hormone (GH) in the acute and late phases after aSAH reflecting possible pituitary gland function and b) eval...

BACKGROUND Poor-grade aneurysmal subarachnoid hemorrhage (aSAH) is associated with very high mortality and morbidity. Our limited knowledge on predictors of long-term outcome in poor-grade patients with aSAH definitively managed comes from retrospective and prospective studies of small case series of patients in single center. The purpose of the AMPAS is to determine the long-term outcomes in p...
