The Impact of Diabetes on Alzheimer’s Disease
Diabetes has been known to affect Alzheimer’s disease (AD) adversely [1, 2]. A recent article postulated that the mechanism for this occurrence was comprised of four underlying malfunctions.

Is It Really Safe Living Alone with Dementia?
We read with interest the article by Eichler et al. [1] that indicates that a high proportion of community-dwelling people with dementia live alone. The authors concluded that people with dementia living alone did not seem to be at an increased health risk, even if they lacked the support of an informal caregiver. We would like to comment on safety issues about living alone with dementia.

Epidemiological trends may help clarify the role of infection in etiology of Alzheimer’s disease
The editorial paper by Itzhaki et al. [1] addresses critically important questions about the role of infection in etiology of Alzheimer's disease (AD). We believe that in addition to the evidence of infectious nature of AD that have been described in the paper, one more type of the evidence must be taken into account and routinely included in consideration of AD mechanisms.

Inhalable curcumin is a potential treatment for herpes simplex virus type 1-associated Alzheimer’s disease
Herpes simplex virus type 1 (HSV-1) DNA is frequently detected in the aged brains of both normal individuals and patients with Alzheimer’s disease (AD) [1]. In recent studies, the reactivation of HSV-1 in the brain is a potent risk factor for the development of AD [1]. Reactivated HSV-1 can cause an increased formation and accumulation of amyloid-β (Aβ) and abnormally phosphorylated tau. Moreover, HSV-1-mediated disruption of autophagy in neurons may also contribute to the accumulation of these abnormal proteins [2].

Further verification of the lack of correlation between Lyme disease and deaths due to Alzheimer’s disease
In 2014, O’Day and Catalano published a JAD article presenting statistical evidence that Lyme disease was not a cause of Alzheimer’s disease [1]. A recent report by Phillip J. Baker, Ph.D., who is the Executive Director of the American Lyme Disease Foundation, has validated this conclusion using different statistical methodology and more recent data [2]. To quote Dr. Baker, “An analysis of the data by linear regression analysis generates a correlation coefficient of 0.0753 (t= 0.262 for 12 degrees of freedom; p >0.05.

Adverse Side Effects of Intranasal Detemir Insulin in the SNIFF Trial
Insulin signaling is impaired in Alzheimer’s disease [1]. In the SNIFF Trial, Claxton et al. have reported that long-acting intranasal insulin Detemir improves cognition for adults with mild cognitive impairment or early-stage Alzheimer’s disease [2]. Adverse effects included mild rhinitis. In an earlier publication, Craft et al. note 8.3% nosebleeds and 16.7% rhinitis with a 20 IU intranasal insulin dose [3].

Non-Steroidal Anti-Inflammatory Drugs and Risk of Alzheimer's Disease
In their updated systematic review and meta-analysis, Wang and colleagues [1] identified 12 cohort studies, 5 case-control studies, and 1 randomized clinical trial (RCT). Based on an aggregate measure emanating from adjusted risk and hazard ratios, they reported that, within a meaningful degree of heterogeneity, non-steroidal anti-inflammatory drugs (NSAIDs) are statistically significantly associated with a 28% reduced risk of Alzheimer’s disease (AD) in the general population.

No Evidence for a Recessive Effect of TMEM106B rs1990622 Variant in the General Population
We read with interest the article by Hernández et al. on the TMEM106B genetic variant rs1990622 that modifies the risk for frontotemporal dementia (FTD) [1]. Although the authors were underpowered to detect a significant association with FTD risk in their case-control study (n/N=146/381), the effect was concordant with the expected direction and slightly decreased in p-value under a recessive model. Similarly, meta-analysis of published data was more significant assuming a recessive effect for the rs1990622 CC genotype.

Spinal Needles for Lumbar Puncture
We read with dismay the report ‘Feasibility of Lumbar Puncture in the Study of Cerebrospinal Fluid Biomarkers for Alzheimer’s Disease: A Multicenter Study in Spain’ [1]. In 2005, the Report of the Therapeutics and Technology Assessment Subcommittee of the American Academy of Neurology recommended the use of atraumatic needles for lumbar puncture [2]. This was based on only one study in the neurology literature, but overwhelming evidence in the anesthesiology literature [3]. We find it astounding that in 2014, cutting edge-tipped spinal needles are still being used for this purpose.
