Bilingualism as a Contributor to Cognitive Reserve Critique - Article Example

The weakness of the article starts from the introduction. First, the authors affirm that there exists an imbalance between brain atrophy and the level of cognitive functioning. However, the authors describe that the relationship between the two is poorly understood. Second, the authors refute the credibility of the use of the cognitive reserve. The authors raise doubts about the correlation nature. However, even after raising doubts, they go on to use it in the study.

On the other hand, the authors agreed to have used computed tomography (CT) scans of participants with probable AD while the article talks of research done on individuals with AD (Schweizer et al, 2012). As a result, doubt is raised about the credibility of the participants used in the research. Moreover, there is a high chance the result would fail to support the hypothesis based on the number of participants in the study. For example, 40 patients were relied upon to carry out the study. In contrast, none of the research relied upon in the introduction involved such few number of participants. The research relied on hundred of participants due to the seriousness required for such analysis.

In addition, the article develops a high sense of credibility. First, the article introduction relied on several other research carried out before on the topic. As a result, any claim made by authors in the introduction is supported by scientific research done before. Moreover, the article's clarity is achieved by relying on a method that had been tried before in testing the hypothesis. As a result, the article does not raise any doubt about the procedure of estimating whether the hypothesis is true or false. The method is relied on to test the CR hypothesis. Moreover, the article has demonstrated a high standard of ethics. For example, the study first sought approval from the Hospital Ethics Board (Schweizer et al, 2012).

However, the article might have faced some limitations. One of such limitations may have been getting a clear response from participants as they are physiologically challenged. Moreover, the other limitation may have been in getting an adequate number of participants.

There are several things to learn from the article. First, I have identified that improved mental function may pose a challenge in the future. However, the article was not appealing due to the use of jargon only understood by people specializing in the field of study.

A repeat of the experiment could enhance the study in various ways. The number of participants could be increased. Moreover, I would like to know what changes take place in the brain due to high mental function that increases the potentiality of AD.
