Electrophysiological correlates of feedback processing in subarachnoid hemorrhage patients.

Patients with subarachnoid hemorrhage (SAH) secondary to anterior communicating artery (AComA) aneurysm rupture often experience deficits in executive functioning and decision-making. Effective decision-making is based on the subjects' ability to adjust their performance based on feedback processing, ascribing either positive or negative value to the actions performed reinforcing the most adaptive behavior in an appropriate temporal framework. A crucial brain structure associated to feedback processing is the medial prefrontal cortex (mPFC), a brain region frequently damaged after AComA aneurysm rupture.

Outcomes After Direct Thrombectomy or Combined Intravenous and Endovascular Treatment Are Not Different.

Background And Purpose: Whether intravenous thrombolysis adds a further benefit when given before endovascular thrombectomy (EVT) is unknown. Furthermore, intravenous thrombolysis delays time to groin puncture, mainly among drip and ship patients.

Methods: Using region-wide registry data, we selected cases that received direct EVT or combined intravenous thrombolysis+EVT for anterior circulation strokes between January 2011 and October 2015.

Decision-making impairment on the Iowa Gambling Task after endovascular coiling or neurosurgical clipping for ruptured anterior communicating artery aneurysm.

Objective: To investigate decision-making deficits after anterior communicating artery aneurysm (ACoA) rupture and to compare the effects of two treatments.

Method: The sample included 40 patients with subarachnoid hemorrhage secondary to ruptured ACoA with a favorable neurological outcome and a control group of 31 subjects matched by age, sex, and years of education. Twenty patients had surgical interventions (clipping) and 20 had received endovascular treatment.

Olfactory dysfunction after subarachnoid hemorrhage caused by ruptured aneurysms of the anterior communicating artery. Clinical article.

Object: Olfactory dysfunction has an important impact on quality of life. In patients with subarachnoid hemorrhage (SAH), anosmia has mainly been reported after surgery for aneurysms of the anterior communicating artery (ACoA). The authors studied whether and how frequently patients with ACoA aneurysms present with smell identification deficits in 2 treatment groups (endovascular and surgical treatment).
