“…Theta wave activity has been linked to both verbal and non-verbal memory (Kahana, Seelig, & Madsen, 2001) and may be particularly associated with retrieval (Ward, 2003), which is required for successful performance on tasks of verbal fluency. Further, Uclés, Almárcegui, Lorente, Romero, and Marco (1997) demonstrated a significant improvement in theta power following carotid endarterectomy in patients with carotid artery stenosis, which correlated significantly with an improvement in category verbal fluency. In light of the evidence linking theta band activity to aging and to language-based cognitive tasks, the current study focused on theta power as a potential neurophysiological moderator of age-related change on tasks of verbal fluency.…”

The purpose of this study was to examine the impact of age, sex, and education on category and letter verbal fluency task performance. A secondary goal was to examine whether resting EEG theta power in bilateral frontal and temporal lobes impacts age-associated decline in verbal fluency task performance. A large sample (N = 471) of healthy, normal participants, age 21-82, was assessed for letter fluency (i.e., FAS), and for category fluency (i.e., Animal Naming), and with a 32-channel EEG system for 'eyes-open' resting theta power. The effects of age, sex, and education were examined using analyses of variance. Correlation analyses were used to test the impact of theta power on age and fluency performance by controlling for the effects of theta when examining the relationship between the other two variables. The results indicated that performance on both fluency tests declined linearly with age, but that the rate of decline was greater for category fluency. These age changes were not associated with education level, and there were no sex differences. While theta power was negatively associated with age and positively associated with Animal Naming performance, it did not moderate the relationship between the two. The differential age-associated decline between category and letter fluency suggests separate neurobiological substrates underlying the two domains of performance, which is not related to theta activity.

“…This is similar to an improvement in cognitive functions after carotid endarterectomy, where severe internal carotid stenosis prior to treatment can cause a cerebral hypoperfusion with a subsequent cognitive deficit. [19][20][21][22] A total of eight patients (observed or after embolization) received LGK treatment. This was not emphasized in the results because various reports in the literature show minimal sequelae of stereotactic radiosurgery treatment on cognitive function.…”

The treatment of brain arteriovenous malformations (AVMs) has been studied extensively. With the use of the Spetzler-Martin (S-M) grading system, patients can be informed appropriately about their possible surgical risks. This does not hold true for their neuropsychological sequelae, which have not been studied widely. We evaluated the neuropsychological outcome of our patients treated for brain AVMs. Of 113 patients treated for a brain AVM between 2001 and 2009, 66 patients were enrolled in the study. All patients underwent treatment at our institution and neuropsychological testing 2 years later using a test battery constructed specifically for this study. A control group consisted of 10 subjects without any neurologic disease. When the whole cohort was analyzed, no significant differences were found between the groups distinguished by hemorrhage, gender, or hemispheric dominance. Patients with S-M IV and V scores fared significantly worse than patients with S-M I to III. Patients who presented with epilepsy scored lower than patients presenting with other symptomatology, but the difference had only borderline significance. When we analyzed patients according to the presence or absence of obliteration after treatment and compared these with the control group, we found no significant differences. When the patients with an obliterated AVM after treatment were subdivided according to treatment modality, there were no significant differences in their S-M groups compared with the control group. Similarly, those patients with nonobliterated AVMs analyzed according to their S-M grade showed a borderline significant difference, with S-M IV and V having a worse neuropsychological outcome compared with the other groups. Patients harboring nonobliterated high-grade AVMs (S-M IV and V) scored worse than patients with nonobliterated AVM S-M grades I to III. This could be explained by the steal phenomenon. No differences in neuropsychological testing were found when comparing results according to nidus location. This study lends support to an active treatment policy for cerebral AVMs. Those patients in whom complete obliteration was achieved with treatment scored similarly to the background population, implying active AVM treatment does not cause deterioration in neuropsychological performance. This, together with a> 90% AVM obliteration rate, favors microsurgery as the treatment modality of choice whenever the AVM can be safely resected.

“…The neuropsychologic tests may not be familiar to vascular surgeons, although this topic has been addressed in several recent articles. [1][2][3][4][5][6][7] Comparison with a group without known vascular disease and a group undergoing surgery for lower extremity arteriosclerosis is novel.…”
