In recent years evidence is increasing that vascular disease is associated with cognitive impairment and dementia. Moreover, presence of cerebrovascular disease may intensify the clinical symptoms of Alzheimer's disease (AD). The aim of the study was to determine the prevalence of vascular risk factors in age and sex matched patients with dementia. We studied 109 patients with AD and 37 patients vascular dementia (VD). DSM-III-R test for dementia, NINCDS-ADRDA guidelines for AD and NINDS-ARIEN for VD were applied. RESULTS: Mean age of dementia onset in AD and VD was 65.8 SD 7.8 and 67.4 SD 7.0 years (p > 0.05), the duration of dementia, MMS and GDS for patients with AD and VD was not significantly different. Arterial hypertension was associated in 51.3% VD and 30.3% AD (p < 0.05), hypotension in 11.1 and 23.6% respectively (p > 0.05), atrial fibrillation was similar in AD and VD, coronary artery disease was presents 64.8% AD and 46.8 VD (p > 0.05) and type 2 diabetes in 21.6% and 10.1% (p > 0.05) respectively. No significant differences in serum lipid profile were found in both groups, except two times higher incidence of normal HDL-cholesterol concentration in AD compare to VD. The relation between alcohol consumption, cigarette smoking and head trauma was similar in both types of dementia. CONCLUSION: Vascular disease and AD have to some extent a shared aetiology, and risk factors that they have in common increase the risk of both disorders independently and vascular disease is perhaps involved in the aetiology of AD.  相似文献

We studied the prevalence of dementing disorders in a rural town of Japan (Amino-cho), using a door-to-door two-phase design. Of the 170 persons screened as having cognitive impairment, 142 cases were diagnosed as having dementia. The prevalence (cases/100 aged 65 years older) was 3.8 for all types of dementia, 2.1 for Alzheimer's disease (AD), 1.0 for vascular dementia (VD) and 0.7 for other types of dementia. Among other types of dementia, there were four male patients with dementia with Lewy bodies (prevalence: 0.1), but no patients with frontotemporal lobar degeneration. The overall prevalence was higher in women for AD, while that of VD was the same in both sexes. With results similar to many previous studies in Western countries and some recent surveys in Japan, the present sudy clearly showed that AD is more prevalent than VD.  相似文献

BACKGROUND/AIMS: Attempting to improve the cerebrospinal fluid (CSF) diagnosis of Alzheimer's disease (AD), the neurofilament heavy chain isoform, NfH(SMI35) was compared to other CSF markers [total tau, phospho-tau, amyloid beta 1-42 (Abeta42), the ratio of amyloid beta fragments Abeta42/Abeta40 (Abeta ratio)]. METHODS: CSF levels were determined in patients with AD (n = 109), mild cognitive impairment (MCI, n = 25), frontotemporal dementia (n = 15), vascular dementia (VD, n = 41), and controls (n = 58). RESULTS: CSF NfH(SMI35) was elevated in AD and VD as compared to controls (p < 0.05). Total tau was higher in AD as compared to controls (p < 0.05). CSF phospho-tau was elevated in AD as compared to controls and VD (p < 0.05 each). CSF Abeta42 and Abeta ratios in AD were lower than in MCI and controls (p < 0.05 each). CONCLUSION: The diagnostic potential of NfH(SMI35) is not superior to that of other CSF markers.  相似文献

Event-related brain potentials in response to novel sounds in dementia.   总被引:14,自引:0,他引:14  
OBJECTIVE: Non-target, deviant stimuli generate an earlier latency, front-central novelty P3, whereas correctly detected task-relevant stimuli generate a parietal maximal target P3. We examined whether the P3 component to novel stimuli is affected by dementing processes, and is therefore useful for distinguishing Alzheimer's type dementia (AD) from vascular dementia (VD). METHODS: We recorded ERPs to task-relevant stimuli (target P3) and novel task-irrelevant stimuli (novelty P3) in an auditory oddball task in AD (n = 16), VD (n = 16), and age-matched controls (n = 18). The amplitude, latency, and scalp topography of target and novelty P3 were compared among 3 groups using ANOVA. The relationship between P3 measures and intelligence scores were evaluated by correlation analysis. RESULTS: The amplitude, latency and scalp topography of the target P3 were comparably affected by both AD and VD. However, the amplitude of the novelty P3 was markedly reduced in VD, but not in AD, and the scalp topographics were different in the 3 groups. The amplitude was maximal at frontal sites in controls, at central sites in AD, and at parietal sites in VD. The target P3 latency was prolonged in both AD and VD, whereas the novelty P3 latency was only prolonged in VD. AD was discriminated satisfactorily from VD by using the novelty amplitude at Cz and the ratio of the amplitudes at Fz and Pz as independent variables. CONCLUSIONS: These results suggest that the response to novel stimuli is differentially affected by dementia with degenerative and vascular etiology.  相似文献

Dysregulation of the hypothalamic pituitary gonadal (HPG) axis during aging has been associated with increased risk of cognitive decline and developing dementia. Compared to controls, men with Alzheimer's disease (AD) have been shown to have lower serum testosterone levels and higher serum luteinizing hormone (LH) levels. As serum free testosterone concentration is negatively correlated with LH in older men, the independent contributions of these hormones to the pathogenesis of AD warrants further clarification. To explore this notion, we measured plasma amyloid-beta (Abeta), serum testosterone, serum LH and other biochemical parameters in 40 cognitively normal elderly men. Multiple linear regression analysis revealed that serum LH concentration is the only parameter that significantly correlates with plasma Abeta levels in these men (r=0.5, p=0.041). These results suggest that increased serum LH concentration, rather than lower serum free testosterone, is associated with the accumulation of Abeta in plasma. Larger, longitudinal human studies are needed to determine the significance of LH in the pathogenesis of AD.  相似文献

The effects of carbamazepine (CBZ) therapy and epilepsy on sex hormone plasma levels in male patients with epilepsy were evaluated by measuring the levels of testosterone (T), free testosterone (FT), sex hormone binding globulin (SHBG), estradiol (E2), luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin (PRL), and dehydroepiandrosterone sulfate (DHEAS) and by calculating the free androgen index (FAI) in 23 male patients with epilepsy receiving CBZ medication, in 18 untreated male patients with epilepsy, and in 19 healthy age-matched control subjects. No significant differences in the mean T or FT levels were found between the three groups, but the CBZ-treated patients had significantly higher SHBG levels and their FAI values and DHEAS concentrations were lower. The LH, FSH, PRL, or E2 levels in CBZ-treated and untreated male patients with epilepsy did not differ from the controls. CBZ monotherapy does not significantly change the serum balance of sex hormones; however, CBZ clearly affects the serum levels of SHBG and DHEAS.  相似文献
