International conference on the healthy effect of virgin olive oil.

1. Ageing represents a great concern in developed countries because the number of people involved and the pathologies related with it, like atherosclerosis, morbus Parkinson, Alzheimer's disease, vascular dementia, cognitive decline, diabetes and cancer. 2. Epidemiological studies suggest that a Mediterranean diet (which is rich in virgin olive oil) decreases the risk of cardiovascular disease. 3. The Mediterranean diet, rich in virgin olive oil, improves the major risk factors for cardiovascular disease, such as the lipoprotein profile, blood pressure, glucose metabolism and antithrombotic profile. Endothelial function, inflammation and oxidative stress are also positively modulated. Some of these effects are attributed to minor components of virgin olive oil. Therefore, the definition of the Mediterranean diet should include virgin olive oil. 4. Different observational studies conducted in humans have shown that the intake of monounsaturated fat may be protective against age-related cognitive decline and Alzheimer's disease. 5. Microconstituents from virgin olive oil are bioavailable in humans and have shown antioxidant properties and capacity to improve endothelial function. Furthermore they are also able to modify the haemostasis, showing antithrombotic properties. 6. In countries where the populations fulfilled a typical Mediterranean diet, such as Spain, Greece and Italy, where virgin olive oil is the principal source of fat, cancer incidence rates are lower than in northern European countries. 7. The protective effect of virgin olive oil can be most important in the first decades of life, which suggests that the dietetic benefit of virgin olive oil intake should be initiated before puberty, and maintained through life. 8. The more recent studies consistently support that the Mediterranean diet, based in virgin olive oil, is compatible with a healthier ageing and increased longevity. However, despite the significant advances of the recent years, the final proof about the specific mechanisms and contributing role of the different components of virgin olive oil to its beneficial effects requires further investigations.

Vascular risk factors, incidence of MCI, and rates of progression to dementia.

OBJECTIVE: To estimate prevalence, incidence, and rate of progression of mild cognitive impairment (MCI) to dementia and correlated vascular risk factors with incident MCI and its progression to dementia. METHODS: The authors evaluated 2,963 individuals from the population-based sample of 5,632 subjects 65 to 84 years old, at the first (1992 to 1993) and second survey (1995 to 1996) of the Italian Longitudinal Study on Aging (ILSA), with a 3.5-year follow-up. Dementia, Alzheimer disease (AD), vascular dementia (VaD), other types of dementia, and MCI were classified using current clinical criteria. RESULTS: Among the 2,963 participants, 139 MCI patients were diagnosed at the first ILSA survey. During the 3.5-year follow-up, 113 new events of MCI were diagnosed with an estimated incidence rate of 21.5 per 1,000 person-years. We found a progression rate to dementia (all causes) of 3.8/100 person-years. Specific progression rates for AD, VaD, and other types of dementia were 2.3, 1.3, and 0.3/100 person-years. Furthermore, age was a risk factor for incident MCI (RR: 5.93, 95% CI: 3.17 to 11.10), while education was protective (RR: 0.06, 95% CI: 0.03 to 0.10), and serum total cholesterol evidenced a borderline nonsignificant trend for a protective effect. There was a nonsignificant trend for stroke as a risk factor of progression of MCI to dementia. CONCLUSIONS: In this population, among those who progressed to dementia, 60% progressed to AD and 33% to VaD. Vascular risk factors influence incident mild cognitive impairment and the rate of progression to dementia.

Mediterranean diet and cognitive decline.

OBJECTIVE: To investigate the possible role of diet in age-related cognitive decline (ARCD) and cognitive impairment of both degenerative (Alzheimer's disease, AD) and vascular (vascular dementia, VaD) origin. DESIGN: Literature review. RESULTS: In an elderly population of southern Italy with a typical Mediterranean diet, high energy intake of monounsaturated fatty acids (MUFA) appeared to be associated with a high level of protection against ARCD. In addition, dietary fat and energy in the elderly seem to be risk factors, while fish consumption and cereals are found to reduce the prevalence of AD in European and North American countries. Finally, the relative risk of dementia (AD and VaD) was lower in the subjects of a French cohort who drank three or four glasses of red wine each day compared with total abstainers. CONCLUSION: Essential components of the Mediterranean diet--MUFA, cereals and wine--seem to be protective against cognitive decline. As such, dietary antioxidants and supplements, specific macronutrients of the Mediterranean diet, oestrogens and anti-inflammatory drugs may act synergistically with other protective factors, opening up new therapeutic interventions for cognitive decline.

Vascular risk and genetics of sporadic late-onset Alzheimer's disease.

In recent years, it is becoming apparent that genes may play an important role in the development of late-onset Alzheimer's disease (LOAD), and genetic studies could unravel new clues. Based on a growing vascular hypothesis for the pathogenesis of LOAD and other dementias, there is increasing interest for environmental and genetic vascular factors. Polymorphisms in different susceptibility genes already implicated in vascular disease risk are now also being suggested as possible genetic markers for increased risk of developing LOAD; however, many of these studies have shown conflicting results. Thus far, the apolipoprotein E (APOE) gene seems to be the only vascular susceptibility factor that is agreed to play a role in the multifactorial pathogenesis of AD although emerging genetic and biological evidence is now strengthening the case for additional inclusion of angiotensin I-converting enzyme 1 (ACE1) into this category. This review will focus on the current knowledge on genetic and nongenetic vascular factors likely to be involved in LOAD, with special emphasis placed on the APOE and ACE1 genes.

The role of diet in cognitive decline.

Recent findings suggest a possible role of diet in age-related cognitive decline, and cognitive impairment of both degenerative (Alzheimer's disease, AD) or vascular origin. In particular, in an older population of Southern Italy with a typical Mediterranean diet, high monounsaturated fatty acids energy intake appeared to be associated with a high protection against cognitive decline. In addition, dietary fat and energy in older people seem to be risk factors, while fish consumption and cereals are found to reduce the prevalence of AD in the European and North American countries. Moreover, foods with large amounts of aluminium-containing additives or aluminium from drinking water may affect the risk of developing AD. Vitamin deficiencies, especially vitamin B6, B12 and folates, and antioxidant deficiencies (vitamins E and C) could also influence the memory capabilities and have an effect on cognitive decline. Dietary anti-oxidants and supplements and specific macronutrients of the diet may act synergistically with other protective factors opening new possibilities of intervention for cognitive decline.

Lipoprotein(a), apolipoprotein E genotype, and risk of Alzheimer's disease.

OBJECTIVES: To explore the possible role of serum lipoprotein(a) (Lp(a)), apolipoprotein E polymorphism, and total cholesterol (TC) serum concentrations in Alzheimer's disease (AD). METHODS: Lp(a) serum concentrations, apolipoprotein E genotypes, and TC serum concentrations were determined in 61 patients with a diagnosis of probable AD and in 63 healthy unrelated age matched controls. Genomic DNA was obtained and amplified by polymerase chain reaction and apolipoprotein E genotypes were defined following a previously described procedure. RESULTS: Lp(a) serum concentrations were significantly associated in a non-linear relation with an increased risk for AD, independently of apolipoprotein E genotypes and sex and dependent on age (truth association) and TC serum concentrations (spurious association). The effect of age adjusted for TC on the odds of having AD increased non-linearly with increasing Lp(a) serum concentrations, with a plateau between 70 and 355 mg/l (odds ratio 11.33). For Lp(a) serum concentrations > or = 360 mg/l, the effect of age (> or = 72 years) was associated with a reduction in odds of having AD (odds ratio 0.15). CONCLUSION: It is suggested that increased Lp(a) serum concentrations, by increasing the risk for cerebrovascular disease, may have a role in determining clinical AD.

F175S change and a novel polymorphism in presenilin-1 gene in late-onset familial Alzheimer's disease.

We analyzed at the molecular level with presenilin-1 (PS-1) and apolipoprotein E (apoE) genotyping the affected subjects and asymptomatic relatives of an Italian family with several members affected by late-onset familial Alzheimer's disease (AD). The screen for PS-1 gene mutations revealed a novel missense substitution phenylalanine 175 to serine in 1 of the affected individuals and 2 asymptomatic sons of the patient. This change was not found in other relatives of this family, as well as in 60 individuals with sporadic late-onset AD and 40 normal controls. Furthermore, a GG/TT substitution in the 3' end of intron 6 at the boundary with exon 7 was found in all relatives of the second and third generations of this family. All the affected relatives were female homo- or heterozygotes for apoE epsilon4 allele. This study provides evidence that a PS-1 gene missense change does not necessarily associate with early-onset disease, and can occur in single cases affected by late-onset disease.

Apolipoprotein E in Southern Italy: protective effect of epsilon 2 allele in early- and late-onset sporadic Alzheimer's disease.

Apolipoprotein E (apoE) polymorphism was evaluated in 81 sporadic late onset Alzheimer's disease (LOAD) patients, 28 sporadic early-onset Alzheimer's disease (EOAD) and 92 sex- and age-matched healthy controls from Apulia, Southern Italy. ApoE genotypes were determined by the polymerase chain reaction-restriction fragment length polymorphism method. The frequency of apoE epsilon 4 allele was significantly higher in EOAD patients than in the control group, but not in LOAD patients. Furthermore, EOAD patients carrying epsilon 4 allele had lower age at onset of AD symptoms (about 4. 5 years). In the whole sample, epsilon 4 was associated to AD by an odds ratio of 2.14, while it increased up to 6.55 in < 65 years old subjects. Finally, in both < 65 and > or = 65 subgroups of subjects, epsilon 2 played a protective role against the development of AD. It is concluded that the geographic decreasing trend of epsilon 4 allele and the age at onset may influence the association of apoE polymorphism with sporadic AD in a Southern Italian sample.

[Age-related cognitive decline: evaluation and prevention strategy].

The age-related decline of cognitive functions generally refers to a mild deterioration in memory performance, executive functions, and speed of cognitive processing. The terms "age-related cognitive decline" (ARCD) and "aging-associated cognitive decline" have been proposed recently to indicate an objective decline in cognitive functioning associated to the ageing process but within normal limits given the person's age. Whether ARCD is expression of a normal ageing process or represents a distinct clinical entity or, eventually, is a continuum with dementia is, at present, difficult to establish. The causes of ARCD are unknown, but some studies have suggested that it may be prevented. Avoidance of cardiovascular and other chronic diseases, high educational level, and maintenance of vision and hearing have been identified as protective factors from ARCD. On the contrary, hypertension, effects of altered metabolism of steroid hormones, smoking, low-complexity occupation, higher density of persons/bedroom in home, and low level of physical activity have been identified as risk factors for ARCD. Recent findings suggest a possible role of diet in the ARCD. In fact, in an elderly population of Southern Italy with a typical Mediterranean diet, high monounsaturated fatty acids energy intake appeared to be associated with a high protection against cognitive decline. Dietary antioxidants, specific macronutrients, estrogens, and anti-inflammatory drugs, may act synergistically with other protective factors, opening new therapeutic interventions for cognitive decline.

Decreased frequency of apolipoprotein E epsilon4 allele from Northern to Southern Europe in Alzheimer's disease patients and centenarians.

Apolipoprotein E (apoE) polymorphism was studied in 79 sporadic late onset Alzheimer's disease (LOAD) patients, 125 unrelated caregivers or volunteers (19-80 years), and 67 centenarians from Apulia, Southern Italy. The frequency of apoE epsilon2 allele was higher in centenarians than in LOAD patients, while epsilon4 was lower. In middle-aged adults, the epsilon4 allele frequency was higher than in centenarians. The epsilon4 allele frequency was lower in healthy adults than in LOAD patients, while epsilon2 was higher. Compared with the allele frequencies of Northern and Central European countries, a geographic trend for epsilon3 and epsilon4 alleles in LOAD and middle-aged adults was observed. The frequency of epsilon3 increased from Northern to Southern Europe, while epsilon4 decreased significantly. In centenarians, epsilon2 showed a North-South increasing pattern, while epsilon4 was in opposite trend.

High monounsaturated fatty acids intake protects against age-related cognitive decline.

OBJECTIVE: To study the relationships between dietary macronutrient intakes and age-related changes in cognitive functions. METHODS: We investigated these associations in the prevalence survey (1992 through 1993) of the Italian Longitudinal Study on Aging (ILSA). The population-based sample of 5,632 subjects of the ILSA, age 65 to 84 years, was identified from the electoral rolls of eight Italian municipalities. In this study, standardized test batteries assessing global cognitive functions (Mini-Mental State Examination [MMSE]), selective attention (Digit Cancellation Test [DCT]), and episodic memory (Babcock Story Recall Test), and a semi-quantitative food frequency questionnaire evaluating macronutrient energy intakes, were performed on 278 nondemented elderly subjects from the randomized cohort of Casamassima, Bari (n = 704). RESULTS: There was an inverse relationship between monounsaturated fatty acids (MUFAs) energy intake and cognitive decline (MMSE < 24). The effect of education on the odds of having a MMSE score <24 decreased exponentially with the increase of MUFA intakes (over 2,400 kJ; odds ratio, 0.69). Moreover, a significant inverse association was observed between MUFA intakes and DCT score (odds ratio, 0.99). No association was found between nutritional variables and episodic memory. CONCLUSIONS: In an elderly population of Southern Italy with a typical Mediterranean diet, high MUFA intakes appeared to be protective against age-related cognitive decline. Prospective clinical trials are needed to evaluate the impact of specific dietary macronutrient intakes on the age-related changes of cognitive functions.
