A Role for Mycobacterium in Alzheimer’s Disease?

We looked forward to Lowry’s “Alzheimer's disease: protective effects of Mycobacterium vaccae, a soil-derived mycobacterium with anti-inflammatory and anti-tubercular properties, on the proteomic profiles of plasma and cerebrospinal fluid in rats” publication in the Journal of Alzheimer’s Disease [1] as an often-overlooked possibility towards Alzheimer’s disease (AD) genesis.

Plasma amyloid-β oligomerization tendency levels are increased with age in healthy subjects

We have well received the research published by Youn et al. that reports the potentiality of plasma amyloid-β (Aβ) oligomerization levels as a diagnostic biomarker in Alzheimer’s disease (AD) [1]. Many studies have claimed that there is a positive correlation between the risk of AD and plasma oligomeric Aβ (OAβ) levels [2-4]. Generally, the prevalence of AD increases with age, which leads to the hypothesis that the occurrence of cases with higher levels of plasma oligomerization tendency level increases with age.

Infection and Alzheimer’s Disease: Will SARS-Cov-2 Be Next?

We read a commentary by Naughton and colleagues published in your journal with extreme interest regarding the potential novel role of Coronavirus Disease-19 (COVID-19) in Alzheimer’s Disease (AD) [1]. In addition, we also read a review by Fotuhi and colleagues in this journal, the neurological complications triggered by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-Cov-2) and the possible mechanism of the connection between SARS-Cov-2 and the brain [2]. Their views are inspiring for neurologists who are concerned about the neurodegenerative diseases following COVID-19.

Letter to the Editor: Comment on “Oral Monosodium Glutamate Administration Causes Early Onset of Alzheimer’s Disease-like Pathophysiology in APP/PS1 Mice"

This letter refers to the article “Oral Monosodium Glutamate Administration Causes Early Onset of Alzheimer’s Disease-like Pathophysiology in APP/PS1 Mice” by Fuchsberger et al. [1], reporting that oral administration of MSG accelerated the onset of pathophysiological and behavioral symptoms in APP/PS1 mice, a genetically modified animal model of Alzheimer’s disease (AD).

Comment on Reliability and validity of the Chinese version of the Mild Behavioral Impairment Checklist for screening for Alzheimer’s disease

I read with interest the study of Cui et al. [1] assessing the reliability and validity of the Chinese version of Mild Behavioral Impairment-Checklist (MBI-C) in Alzheimer’s disease (AD) patients. The authors address key elements of the validation process, but their conclusions—the Chinese MBI-C is high in validity and reliability as well as superior to Neuropsychiatric Inventory Questionnaire—are unfortunately weakened by some persistent misconceptions of scale validation in general, and some common issues in neurodegenerative disease research.

Labelling of Statistical Output of Cytoarchitecture-Defined Variables in FreeSurfer Version 6

In our recent paper, Fung et al. [1], we investigated the validity of automated FreeSurfer protocols in a group of routine clinical brain MRI scans. One structure of interest was the entorhinal cortex, in which we compared manual segmentation against automated segmentation generated by the ex vivo protocols of Fischl et al. [2] and Augustinack et al. [3] found in FreeSurfer version 6.

Can Tau Formation be Independent of Amyloid-β in Alzheimer’s Disease?

I read the article on the possibility of sparing Alzheimer’s disease (AD) by nonsteroidal anti-inflammatory drugs [1] with great interest. It is stated that AD is characterized by the start of amyloid-β (Aβ) deposition in brain with consequent decreases in the cerebrospinal fluid (CSF), and therapeutic opportunities at this initial stage are at their highest. It is also stressed that biomarker studies suggest that phase 2 (Braak staging) sets in about 5 years later.

Chronic Traumatic Encephalopathy

Recently, Zuckerman et al. [1] presented an interesting history of chronic traumatic encephalopathy (CTE), previously referred to as dementia pugilistica [2], beginning from Hippocrates up to recent publications, with emphasis on contact sports and American football. With regard to CTE in boxers, except for the first report of "punch drunk" [3] and a few others [4], they unfortunately did not refer to a number of other important contributions about brain damage in boxers, many of them having been mentioned previously [5].

Effective discrimination with the recency ratio between Alzheimer’s disease and dementia with Lewy bodies

Despite neuropsychological differences between individuals with Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB), overlap in performance has been observed, including analogous scores in memory tests (Rey Auditory Verbal Learning, AVLT; e.g., [1]). All the while, differential diagnosis remains a costly exercise.
