Atrial Fibrillation and Dementia: What is the Link?

Regarding atrial fibrillation (AF), post-stroke cognitive impairment (PSCI), and post-stroke dementia (PSD), a recently published article in October 2017 by Chander and colleagues [1] reported that AF is a significant and independent risk factor for PSCI even after correction of other risk factors and that we should do follow up for patients with AF regardless of infarction type. This agrees with a meta-analysis done in 2012 [2]. Also in a systemic review done in 2017 [3], stroke patients with AF have a risk of dementia which is 1.68 times compared with patients without AF.

Dietary factors for prevention of late-onset Alzheimer’s disease and related dementia: what is optimal?

Solfrizzi et al. [1] recently published a systematic review of observational studies published between 2014 to 2016 on dietary factors and late-life cognitive disorders. While the authors relayed the growing promise and potential of diet to change the course of late-onset Alzheimer’s disease and related dementia, their conclusion—that certain foods that have been thought to increase health risk are not as damaging as previously described—is not consistent with the emerging unifying concepts on protective dietary factors for Alzheimer’s disease [2-4].

The Cognitive Basis for Florence Foster Jenkins' “Tone Deafness"

The brilliant film portrayal by Meryl Streep of the tone-deaf diva Florence Foster Jenkins is amplified in the historian Darryl W. Bullock's fine new book, Florence ! Foster !! Jenkins !!! the Life of the World's Worst Opera Singer (Overlook Press, New York, 2016). I offer here a scientific postulation for this striking example of "dysmusia " (or tune-deafness), of which she was quite likely cognitively unaware.

The Pathway to Alzheimer’s Disease from Spirochetes to Amyloid-β

Recently, Miklossy has shown Borrelia cultured from brains of Alzheimer’s disease (AD) not only grew organisms, but those organisms made biofilms, amyloid-β protein precursor (AβPP), and amyloid-β (Aβ) in vitro as well [1]. With that observation, the major events in the pathogenesis of this dreaded disease have been made much clearer. They (major events) originate in most cases of the disease with spirochetes; Aβ, which is a constant in the disease, assumes a lesser role.

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.
