Regarding Article: Arendash GW et al. (2010) J Alzheimers Dis 19, 191-210

We thank Dr. Kumlin and colleagues for their insightful comments regarding our paper [1]. Inasmuch as we were unaware of their earlier study involving EMF exposure to normal rats [2], we did not include it among the references in our paper and apologize for this oversight. Kumlin et al. [2] did indeed provide initial evidence that long-term EMF exposure (2 hrs/day, 5 days/week, for 5 weeks) can improve cognitive performance in rodents. It is important to note, however, that they provided EMF exposure to very young rats from 3-8 weeks of age.

In a recent issue of Journal of Alzheimer’s Disease, Zhang and colleagues presented interesting data concerning the cholinergic deficit in Alzheimer’s disease (AD) [1]. These results demonstrated decreases in the activity of acetylcholinesterase (AChE) and reduced mRNA levels of α4 and β2 nicotinic acetylcholine receptor (nAChR) subunits in peripheral blood of patients with AD in an elderly Chinese population.

Response to: Sorensen A (2009) J Alzheimers Dis 16, 451-465

To the Editors, Like many with an interest in the field of Alzheimer’s disease I was intrigued to read the recent paper in JAD which purported to report the ‘scientific productivity and impact of the top 100 investigators in the field’ [1]. As an outsider to the study of ‘scientometrics’ it appeared a thorough piece of work though there were few indications as to its actual aims.

A very interesting article by Arendash et al. (1) was published in the January 2010 issue of Journal of Alzheimer’s Disease. The results suggested that exposure to radiofrequency (RF) radiation similar to that emitted by mobile phones may  provide cognitive benefits both in normal mice and  in a transgenic mouse model of Alzheimer’s disease (AD).
