Age-dependent effects of carotid endarterectomy or stenting on cognitive performance
Although evidence is accumulating that age modifies the risk of carotid angioplasty and stenting (CAS) versus endarterectomy (CEA) for patients with significant carotid stenosis, the impact of age on cognition after either CEA or CAS remains unclear. In this study, we analyzed the effects of age on...

description | Although evidence is accumulating that age modifies the risk of carotid angioplasty and stenting (CAS) versus endarterectomy (CEA) for patients with significant carotid stenosis, the impact of age on cognition after either CEA or CAS remains unclear. In this study, we analyzed the effects of age on cognitive performance after either CEA or CAS using a comprehensive neuropsychological test battery with parallel test forms and a control group to exclude a learning effect. The neuropsychological outcomes after revascularization were determined in 19 CAS and 27 CEA patients with severe carotid stenosis. The patients were subdivided according to their median age ( |

The patients were subdivided according to their median age (<68 years and ≥68 years); 27 healthy subjects served as a control group. In all patients clinical examinations, MRI scans and a neuropsychological test battery that assessed four major cognitive domains were performed immediately before, within 72 h, and 3 months after CEA or CAS. While patients <68 years of age showed no significant cognitive alteration after either CEA or CAS, a significant cognitive decline was observed in patients ≥68 years in both treatment groups (

These results demonstrate an age-dependent effect of CEA and CAS on cognitive functions. In contrast to the recently observed increased clinical complication rates in older subjects after CAS compared with CEA, CEA appears to be associated with a greater, persistent decline in cognitive performance than CAS in this subgroup of patients.</description><identifier>ISSN: 0340-5354</identifier><identifier>EISSN: 1432-1459</identifier><identifier>DOI: 10.1007/s00415-012-6491-9</identifier><identifier>PMID: 22527231</identifier><identifier>CODEN: JNRYA9</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer-Verlag</publisher><subject>Age ; Age Factors ; Aged ; Angioplasty ; Angioplasty, Balloon - adverse effects ; Angioplasty, Balloon - psychology ; Asymptomatic ; Biological and medical sciences ; Carcinoembryonic antigen ; Carotid arteries ; Carotid Stenosis - epidemiology ; Carotid Stenosis - psychology ; Carotid Stenosis - surgery ; Cognition & reasoning ; Cognition Disorders - epidemiology ; Cognition Disorders - psychology ; Cognitive ability ; Endarterectomy, Carotid - adverse effects ; Endarterectomy, Carotid - psychology ; Female ; Humans ; Ischemia ; Learning ; Magnetic resonance imaging ; Male ; Medical sciences ; Medicine ; Medicine & Public Health ; Middle Aged ; Neurology ; Neuropharmacology ; Neuroprotective agent ; Neuropsychological Tests ; Neuropsychology ; Neuroradiology ; Neurosciences ; Original Communication ; Pharmacology.
