        Neuropsychological Outcome One Year after Carotid Revascularization: A before-and-after Study

        Laura Casas-Hernanz,Maite Garolera,Dolors Badenes,Salvador Quintana,Susana Millán,Noemi Calzado,Jorge de Francisco,Josep Royo,Miquel Aguilar 대한혈관외과학회 2017 Vascular Specialist International Vol.33 No.4

        Purpose: The aim of our study was to determine the clinical profile of patients considered cognitive ‘responders’ to surgery in order to establish clinical variables associated with a favorable cognitive performance. Materials and Methods: A total of 70 patients were included in the study. A wellvalidated, comprehensive standardized neurocognitive battery of tests of about 2 hours was administered. Patients were examined twice, 1-week before surgery and 1-year postoperatively. The criterion to be included in the ‘responder’ group was the following: to obtain a positive difference between post-revascularization and pre-revascularization neuropsychological assessment ≥1 standard deviation in ≥2 tests. Results: Twenty-seven patients (38.6%) were cognitive responders to treatment. In bivariate analysis between responders and non-responders, presence of atrophy (P=0.003), small vessels (P=0.577), symptoms (P=0.046), and age (P=0.030) were the factors statistically significant. When comparing cognitive performance before and after carotid revascularization, significant differences were observed in semantic fluency with a lower performance after 12 months (P=0.004, d=0.29), and in the Language index (Repeatable Battery for the Assessment of Neuropsychological Status) (P=0.005, d=0.34). Conclusion: Patients without neurological symptoms, of a younger age and without atrophy and white matter small vessel lesions are better cognitive responders 1-year after carotid revascularization.

        Risk of Cognitive Impairment in Patients With Parkinson’s Disease With Visual Hallucinations and Subjective Cognitive Complaints

        Diego Santos-García,Teresa de Deus Fonticoba,Carlos Cores Bartolomé,Maria J. Feal Painceiras,Maria J. Feal Painceiras,Cristina Martínez Miró,Silvia Jesús,Miquel Aguilar,Pau Pastor,Lluís Planellas,Mari 대한신경과학회 2023 Journal of Clinical Neurology Vol.19 No.4

        Background and Purpose Visual hallucinations (VH) and subjective cognitive complaints (SCC) are associated with cognitive impairment (CI) in Parkinson’s disease. Our aims were to determine the association between VH and SCC and the risk of CI development in a cohort of patients with Parkinson’s disease and normal cognition (PD-NC). Methods Patients with PD-NC (total score of >80 on the Parkinson’s Disease Cognitive Rating Scale [PD-CRS]) recruited from the Spanish COPPADIS cohort from January 2016 to November 2017 were followed up after 2 years. Subjects with a score of ≥1 on domain 5 and item 13 of the Non-Motor Symptoms Scale at baseline (V0) were considered as “with SCC” and “with VH,” respectively. CI at the 2-year follow-up (plus or minus 1 month) (V2) was defined as a PD-CRS total score of <81. Results At V0 (n=376, 58.2% males, age 61.14±8.73 years [mean±SD]), the frequencies of VH and SCC were 13.6% and 62.2%, respectively. VH were more frequent in patients with SCC than in those without: 18.8% (44/234) vs 4.9% (7/142), p<0.0001. At V2, 15.2% (57/376) of the patients had developed CI. VH presenting at V0 was associated with a higher risk of CI at V2 (odds ratio [OR]=2.68, 95% confidence interval=1.05–6.83, p=0.039) after controlling for the effects of age, disease duration, education, medication, motor and nonmotor status, mood, and PD-CRS total score at V0. Although SCC were not associated with CI at V2, presenting both VH and SCC at V0 increased the probability of having CI at V2 (OR=3.71, 95% confidence interval= 1.36–10.17, p=0.011). Conclusions VH were associated with the development of SCC and CI at the 2-year follow-up in patients with PD-NC.
