Could a Combination of the Clock Drawing Test and the Mini-Mental Status Examination Be Used to Screen Dementia in a Neurological Setting? Comments with Data from the NEDICES Survey
The interesting paper recently presented in the Journal of Alzheimer’s Disease  suggests, in agreement with one recent report , a utilization of the clock drawing test (CDT), in combination with the Mini-Mental Status Examination (MMSE), as a screening method for Alzheimer’s disease (AD) and mild cognitive impairment (MCI) in a neurological setting. This is a relatively new use of the CDT and MMSE, because both tests are traditionally and preferably employed in these disorders in population- and community-based surveys .

The article by Walton  indicated aluminum is instrumental in causing hyperphosphorylation of tau with subsequent development of neurofibrillary tangle formation. Recently tau has been found to mislocalize to dendritic spines causing early synaptic dysfunction . Aluminum mediated hyperphosphorylation of tau may be a trigger for tau dysfunction and abnormal cellular trafficking with mislocalization to dendrites causing synaptic dysfunction, which probably is an early feature of Alzheimer's disease.

We note that Perucho et al.  cite (reference number 28) a 2007 publication by Pravat K Mandal , and we wish to point out to the authors and your readers that the Biochemistry paper in question was retracted later that same year , as was another article by Mandal , because “the anesthetic concentration of our paper[s] was misrepresented”. Those papers should therefore not be cited as evidence.

We thank Dr. Kumlin and colleagues for their insightful comments regarding our paper . Inasmuch as we were unaware of their earlier study involving EMF exposure to normal rats , we did not include it among the references in our paper and apologize for this oversight. Kumlin et al.  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) . 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.

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’ . 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).
