Recent literature highlights the importance of identifying factors associated with mild cognitive impairment (MCI) and Alzheimer’s Disease (AD). Actual validated biomarkers include neuroimaging and cerebrospinal fluid assessments; however, we investigated non-Aβ-dependent factors associated with dementia in 12 MCI and 30 AD patients. Patients were assessed for global cognitive function (Mini-Mental state examination—MMSE), physical function (Physical Performance Test—PPT), exercise capacity (6-min walking test—6MWT), maximal oxygen uptake (VO2max), brain volume, vascular function (flow-mediated dilation—FMD), inflammatory status (tumor necrosis factor—α ,TNF- α, interleukin-6, -10 and -15) and neurotrophin receptors (p75NTR and Tropomyosin receptor kinase A -TrkA). Baseline multifactorial information was submitted to two separate backward stepwise regression analyses to identify the variables associated with cognitive and physical decline in demented patients. A multivariate regression was then applied to verify the stepwise regression. The results indicated that the combination of 6MWT and VO2max was associated with both global cognitive and physical function (MMSE = 11.384 + (0.00599 × 6MWT) − (0.235 × VO2max)); (PPT = 1.848 + (0.0264 × 6MWT) + (19.693 × VO2max)). These results may offer important information that might help to identify specific targets for therapeutic strategies (NIH Clinical trial identification number NCT03034746).

Tumor necrosis factor α (TNF-α) plays a central role in the pathophysiology of Alzheimer’s disease (AD). Food and Drug Administration–approved biologic TNF-α inhibitors are thus a potential treatment for AD, but they do not cross the blood-brain barrier. In this short review, we discuss the involvement of TNF-α in AD, challenges associated with the development of existing biologic TNF-α inhibitors for AD, and potential therapeutic strategies for targeting TNF-α for AD therapy.

ABSTRACTBackground:The prevalence and factors associated with delays in help seeking for people with dementia in China are unknown.Methods:Within 1,010 consecutively registered participants in the Clinical Pathway for Alzheimer's Disease in China (CPAD) study (NCT01779310), 576 persons with dementia (PWDs) and their informants reported the estimated time from symptom onset to first medical visit seeking diagnosis. Univariate analysis of general linear model was used to examine the potential factors associated with the delayed diagnosis seeking.Results:The median duration from the first noticeable symptom to the first visit seeking diagnosis or treatment was 1.77 years. Individuals with a positive family history of dementia had longer duration (p= 0.05). Compared with other types of dementia, people with vascular dementia (VaD) were referred for diagnosis earliest, and the sequence for such delays was: VaD < Alzheimer's disease (AD) < frontotemporal dementia (FTD) (p< 0.001). Subtypes of dementia (p< 0.001), family history (p= 0.01), and education level (p= 0.03) were associated with the increased delay in help seeking.Conclusions:In China, seeking diagnosis for PWDs is delayed for approximately 2 years, even in well-established memory clinics. Clinical features, family history, and less education may impede help seeking in dementia care.

IntroductionThe Alzheimer's patient assistance relationship is a morally painful experience, most frequently discussed in terms of “burden” in the literature, especially as professionals and institutional intermediaries are underdeveloped in Tunisia.GoalIt is intended to assess the level of burden among caregivers of patients with Alzheimer's disease and to search factors associated with a high level of burden.MethodologyThis is a retrospective descriptive study. Patients were recruited from neurology department of Razi hospital, which were hospitalised between the months of December 2012 and March 2013. The burden was measured using the Zarit inventory.Results and discussionThirty patients were included. The majority female, most caregivers are descendants (60%), then, daughters in law (33%), and finally the spouses (23%). 80% of caregivers lived in the same home as patients. Caregivers were asked about all the items of the grid Zarit. The average burden in our sample is 59.9 + 16 3. We observed that 33% have absent to light burden (score <21), 10% have a light to moderate burden (between 21 and 40), 36, 66% have moderate to severe burden (between 41 and 60) and 50% have a severe burden (>60), according to the classification proposed by Zarit. Sex, kinship and cohabitation with the patient were not associated with a higher burden.ConclusionThe study of factors correlated with high levels of burden aims at finding ways of intervention and support to fight against the isolation of caregivers and the occurrence of anxiodepressive complications.Disclosure of interestThe authors have not supplied their declaration of competing interest.

ABSTRACTAlzheimer's disease represents a significant challenge to the aging population. Since most estimates suggest that AD has a multifactorial etiology, the challenge to find preventative approaches is particularly great. With the aging of the population and the very high incidence from the eighth decade on, the challenge is further enhanced by the need to think of relatively safe interventions given the relative frailty of this elderly population. The need to find safe treatments, or ones with well-understood safety profiles, has led to the examination of known agents for potential dementia-preventing properties. Data supporting these interventions comes from observational studies, laboratory analyses, and clinical trials. Potential mechanisms for prevention of AD include anti-inflammatory and antioxidant approaches. Modulation of risk factors associated with cardiac disease may also reduce the risk of AD. Known agents have been examined for their potential to modify amyloid pathology. Trial designs to address prevention of AD include both primary and secondary prevention studies as well designs to assess slowing disease progression. Information can also be gathered when dementia evaluation is added to ongoing studies. As results from these studies becoming available, we will be able to refine our approach to managing this disease.
