Good Critical Assignment On Reading Of Article Critical Thinking Example

The research question is both relevant and interesting. The Parahippocampal white Volume Predicts ad Risk In Cognitively Normal Old Adults published on 17 Jan 2014, the study found out that PWM atrophy provided a sensitive MRI biomarker of dementia risk among those with normal cognitive function. The abstract begins by examining the previous studies that had been done on the subject. All of the studies documented concentrated on the gray matter and its predictive of the cognitive decline yet very little had been done on the white matter as a probable MRI biomarker predictive of AD. The study investigated Parahippocampal white matter (PWM) retrieved from MRI scan.
The abstract also contains the sample size and how it was arrived at and the details of how the whole research was conducted. There were two dependent sample sizes of 65 older people with a follow up period of 8.5 years between them. There whole process was independent from the findings of the two samples with the result concluding that PWM causes a sensitive MRI of AD dementia risk among the adults with normal cognitive function. The abstract details provide enough evidence to demonstrate the significance and originality of the research. Reading through the article there is enough results to support the findings shown in the abstract.
The experiment design has been used in this study. Experiment design refers to the where the research question is established before the research is carried. Secondly, the variables of the study have been stated: PMW volume (as the independent variable) and Risk in cognitively normal old adults (as dependent variable).The variables has been used to test the hypotheses established under the study. There was a positive correlation on the between the variables consistency and the hypotheses. Secondly, the two sample were independent of each other making the findings to be reliable as it included both genders
