Common carotid artery intima media thickness and post-stroke cognitive impairment

BACKGROUND AND PURPOSE: Acute stroke and other forms of cerebrovascular disease are well-recognized causes of cognitive impairment. Common carotid artery intima media thickness (CCA-IMT) has been associated with certain forms of cerebrovascular disease, but its association with cognitive impairment of vascular origin has not been elucidated. The purpose of this study was to investigate whether CCA-IMT is associated with cognitive impairment 1 year after an acute ischemic stroke. METHODS: A total of 171 consecutive patients with the first ever stroke (mean age 66+/-11.5, 41% female) underwent carotid ultrasonography during hospitalization. Demographic data, vascular risk factors and presenting stroke features were also recorded. One year later, patients' cognitive performance and depression were assessed using the Mini-Mental State Examination (MMSE), and the Montgomery Asberg Depression Rating Scale (MADRS). RESULTS: Cognitive impairment (MMSE score<24) was found in 67 (39%) of the 171 patients. CCA-IMT was significantly associated with cognitive impairment, and this association remained unchanged (OR 1.94; 95% CI 1.19-3.18) after adjustment for demographic data, vascular risk factors, stroke features, other carotid ultrasonography measurements and depression. Older age, low education level, large hemispheric lesions, hyperdense carotid plaques and depression were also independently associated with post-stroke cognitive impairment. CONCLUSIONS: In this study, CCA-IMT was independently associated with cognitive impairment 1 year after an acute ischemic stroke, and thus, it might help with the screening of stroke patients at risk of cognitive impairment.

Tea consumption is associated with cognitive impairment in older Chinese adults

ABSTRACT

Objective: To explore the association between tea consumption and cognitive impairment (CoI).

Methods: 4579 adults (≥60 years) from the Weitang Geratric Diseases Study were assessed for characteristics of tea consumption and cognitive function by administering questionnaires and the Abbreviated Mental Test (AMT), respectively. We divided the subjects into normal cognitive function group (AMT score ≥8) and CoI group (AMT score ≤7). The association between tea consumption and risk of CoI was determined by logistic regression models.

Results: The least-squared means of the AMT scores for the subjects who seldom consumed tea were less favorable than those who habitually consumed tea. An inverse association was found between tea consumption (of any type) and prevalence of CoI (odds ratio = 0.74, 95% confidence interval = 0.57–0.98, P = 0.032). Interestingly, the protective correlation of tea was more obvious in never smokers (odds ratio = 0.63), but vanished in current/former smokers (odds ratio = 1.10). In never smokers, frequency of tea consumption was significantly associated with CoI (P for trend = 0.010).

Conclusion: Habitual tea consumption is suggested to be associated with a decreased risk of CoI among elders in Suzhou, and a higher frequency of tea consumption was associated with a lower prevalence of CoI among never smokers.     

The prevalence of cognitive impairment in an elderly Canadian population

We investigated cognitive impairment in a study of the health of the elderly population of Saskatchewan. Surveys of elderly persons living at home (n = 1267) and living in long-term care facilities (n = 990) were conducted in 1981. Cognitive impairment was assessed by a short 10-item mental status questionnaire previously validated against a clinical diagnosis of dementia in an elderly Canadian population. The prevalence of clinically significant cognitive impairment was found to increase with age and with dependence level in long-term care facilities. We estimate that 7.8% of the elderly population have cognitive impairment consistent with a clinical diagnosis of dementia. Our estimates are compared with those derived from other studies. These findings affirm the importance of dementia as a cause of dependence in the elderly and the need for long-term care facilities to deal with dementia and its consequences. Also, since at least as many persons with cognitive impairment live at home as in long-term care facilities, health care planners must direct attention to the elderly with dementia at home.

Correlating cognitive impairment with carotid atherosclerosis and carotid artery stenosis in patients with acute cerebral infarction*★

BACKGROUND：Studies have demonstrated that carotid atherosclerosis and carotid artery stenosis are closely associated with cognitive impairment in patients with and without clinically evident cerebrovascular disease. OBJECTIVE： To investigate the correlation between the degree of pathological changes in carotid atherosclerosis, carotid artery stenosis, and cognitive impairment in patients with acute cerebral infarction through the use of color Doppler imaging. DESIGN, TIME AND SETTING： The present concurrent, non-randomized, controlled experiment was performed at the Departments of Neurology and Ultrasound, Affiliated Hospital of North Sichuan Medical College between November 2006 and August 2007. PARTICIPANTS： Fifty-five patients with cerebral infarction, consisting of 35 males and 20 females, aged 50–82 years, were admitted to the hospital between November 2006 and August 2007 and recruited for this study. An additional 30 subjects consisting of 18 males and 12 females, aged 47–78 years, that concurrently received a health examination at the same hospital, were also included as normal controls. METHODS： Intima-media thickness （IMT）, plaque shape, size, and echo intensity of all subjects were detected by color Doppler flow imaging. Assessment criteria： IMT 〉 1.0 mm was considered to be intimal thickening, and IMT 〉 1.2 mm was determined to be formed atherosclerotic plaques. In the position of the largest plaque, the degree of carotid artery stenosis was determined by the following formula： （1-cross-sectional area of residual vascular luminal area/vascular cross-sectional area） × 100%. Less than 30% exhibited mild stenosis, 30%-40% moderate stenosis, and 〉 50% severe stenosis. MAIN OUTCOME MEASURES： IMT and the degree of carotid artery stenosis were evaluated by color Doppler flow imaging. The Mini-Mental State Examination （MMSE）, as well as the clinical memory scale, was compared between patients with cerebral infarction and normal controls. RESULTS： In the cerebral infarc

A clinical memory battery for screening for amnestic mild cognitive impairment in an elderly chinese population

Amnestic mild cognitive impairment (MCI) might be more likely to progress to Alzheimer’s disease than single non-memory MCI and multiple domain MCI. After excluding those who did not conform to the inclusion criteria of amnestic MCI or healthy controls, a neuropsychologic battery that included the Mini-Mental State Examination, Clinical Dementia Rating, Chinese version of the Montreal Cognitive Assessment, Instrumental Activities of Daily Living scale and Auditory Verbal Learning Test was performed on 150 amnestic MCI and 150 normal control patients. The Chinese version of the Montreal Cognitive Assessment was measured for its test-retest reliability, sensitivity and specificity. Blood was collected for apolipoprotein E (APOE) genotyping. Compared with the control group, the amnestic MCI group performed significantly worse on all neuropsychological tests, and non-APOE-??4 carriers in the amnestic MCI group performed better than APOE-??4 carriers in the amnestic MCI group. The set of neuropsychological tests in our study could distinguish amnestic MCI participants from normal elderly participants accurately. APOE did have a role in amnestic MCI patients, but the magnitude and mechanism of its influence are not fully understood.
