Background: Many genes and environmental factors linked to Alzheimer’s disease (AD) risk affect lipid metabolism or the cardiovascular system, strongly implicating cerebrovascular and metabolic dysfunction in AD pathogenesis. Although some PUFAs may improve cognitive function in aging individuals, it is still unclear how different PUFAs influence AD neuropathology and cognitive function. Objective: To examine the influence of polyunsaturated fatty acid (PUFA) metabolism on AD-associated cognitive decline, we investigated the relationship between serum PUFA profile and neuropsychological test performance. Methods: Cognitive functioning in patients with probable AD (n = 174, mean age 77.6 years) was examined using the Mini-Mental State Exam (MMSE) and clock drawing test (CDT). Serum samples were obtained for PUFA profile, including the eicosapentaenoic acid/arachidonic acid (EPA/AA) ratio, and measurement of brain natriuretic peptide (BNP) concentration. In the follow-up study, 47 subjects repeated MMSE and CDT after 1 year, According to the second MMSE score, the subjects were divided into the following 2 groups: those with unchanged or improved MMSE score and those with lower MMSE score. A receiver operating characteristic curve was used to evaluate the relationship between the EPA/AA ratio and 1-year cognitive stability. Results: In the cross-sectional study, total MMSE score correlated positively with the EPA/AA ratio and systolic blood pressure (SBP), and negatively with age and diastolic blood pressure (DBP) (p < 0.05). In the follow-up study, the MMSE score was lower than baseline in 20 subjects, whereas it was improved or unchanged in 29 patients. The EPA/AA ratio in the stable group was significantly greater than that in the deteriorating group, suggesting an association between higher EPA/AA ratio and cognitive stability over 1 year. The EPA/AA ratio predicted stability of cognitive performance with a sensitivity of 66% and specificity of 70% (odds ratio = 4.43) when the cut-off was 0.67. Conclusion: Our results suggest that serum EPA concentration strongly influences cognitive performances in AD patients. The EPA/AA ratio was a sensitive indicator of cognitive stability in this patient group.

Background: Alzheimer’s Disease (AD) is still a great global challenge and agents with various mechanisms represent a promising therapeutic opportunity. Theracurmin, a very highly absorbable curcumin formulation, was shown to improve memory and attention in non-demented people. Objective: To investigate the effect of Theracurmin on disease course in elderly patients with mild cognitive impairment (MCI) and AD. Methods: This follow-up study was performed retrospectively on 93 patients with MCI or AD. All patients underwent comprehensive geriatric assessment, including Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MOCA), clock-drawing test, activities of daily living (ADL), at baseline and end of the 6th-month. 19 patients with AD and 17 with MCI were treated with Theracurmin 180 mg/day per oral. Results: MMSE, MOCA and instrumental ADL scores decreased in AD patients that were not treated with Theracurmin (p<0.001, p=0.011, and p=0.004, respectively), whereas these scores remained stable in those treated with Theracurmin. This stabilization in the instrumental ADL was also observed in MCI patients treated with Theracurmin. During the follow-up, three of MCI patients who did not receive Theracurmin progressed to AD, whereas only one patient progressed in those who received it. Conclusion: Theracurmin seems to be a therapeutic option for elderly patients with AD and MCI via providing stabilization of the disease course by preventing progressive loss in cognitive functions and ADLs.

Background. We studied whether heterogeneous profiles of cognitive function are relevant to survival in patients with early Alzheimer's disease.Methods. CAMCOG subscales of cognitive function were used as predictors of survival, together with gender in 157 consecutively referred patients with early Alzheimer's disease. Statistical analysis was performed with Cox proportional hazards analysis and Kaplan–Meier survival curves. Survival rates were compared with those in the general population.Results. Eighty patients (51%) died during the follow-up that extended to 5·7 years, with a median survival of 4·4 years after entry. Only the praxis subscore was statistically significant related to survival (P<0·0001). Its predictive power was based on only two items, including copying ability for a spiral and a three-dimensional house, independent of age, sex, education, overall CAMCOG score, dementia severity and symptom duration. Kaplan–Meier curves for the combined score of these items (0, 1, or 2) showed three groups with significantly different survival rates for both men and women. Comparison of gender specific survival rates with data from the general population showed that excess mortality was statistically significant (P<0·01) higher in men (51%) than in women (21%) after follow-up extending to 5 years.Conclusions. A simple test of copying ability defines subgroups of AD patients with large differences in survival rates. This suggests that parietal lobe impairment is an important predictor of mortality in AD. Also, the course of AD may be more benign in women than in men.

Background and Aims. We previously reported that the administration of traditional Japanese medicines, kihito (Gui-Pi-Tang in Chinese) and kamikihito (Jia-Wei-Gui-Pi-Tang in Chinese), to Alzheimer’s disease (AD) model mice improved memory impairment. There are a few reports that show kihito and kamikihito have a beneficial effect on the cognitive function of AD patients in clinical studies. However, these studies are not comparative and are retrospective studies; thus, more evidence is needed. Therefore, we conducted an open-label, crossover designed clinical trial to investigate the effect of kihito on cognitive function of AD patients. Methods. The inclusion criteria for eligible patients were as follows: (1) imaging diagnosis (magnetic resonance imaging and single-photon emission computed tomography) of AD, (2) a treatment regimen including acetylcholinesterase inhibitors (ChEIs), and (3) a Mini-Mental State Examination (MMSE) score ≥15. The exclusion criteria were as follows: (1) change in ChEI dosage, (2) memantine usage, and (3) MMSE score < 15. To prevent bias in age and baseline cognitive function, patients were divided into two groups: the first group received 2.5 g of kihito extract 3 times/day during the first half of the study (weeks 0-16) and the second group received the same dose of kihito during the second half of the study (weeks 17-32). ChEI dosage did not change during the study period. Patients underwent a cognitive function test during weeks 0, 16, and 32. Cognitive function was evaluated by Japanese versions of the Mini-Mental State Examination (MMSE-J) and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS-J) test. Results. Ten patients completed the clinical trial (4 males, 6 females, average age 71.7 years). MMSE-J scores significantly increased during the kihito intake period. RBANS-J test scores had a slight improvement during the kihito intake period compared with the ChEI alone treatment period, but no significant changes were observed. Conclusion. Kihito improves cognitive function in AD patients.
