Case Studies
Since researchers are interested in examining the effects of disrupted brain areas and conducting experiments for further understanding of an unaffected, normal brain, many individuals with brain damage have volunteered to undergo countless tests to advance our scientific knowledge of the human brain. For example, HM is someone with significant brain damage and participates in a lot of neurological research. Furthermore, he is also the most tested person in neuropsychology. All people who participate are referred to in literature using only their initials to protect privacy.
Patients with RA have exhibited an inability to describe future plans, whether in the near future (e.g., this afternoon) or in the distant future (e.g., next summer) because of their inability to consolidate memories. Also, researchers have found these patients can identify themselves and loved ones in photographs, but cannot determine the time or place the photo was taken. It has also been found that patients with RA greatly differ from the general population in remembering past events.
A few case examples are:
- After a head injury, AB had to relearn personal information. Many of AB’s habits had also changed.
- Patient CD, reported disorientation of place and time following his injuries as well as relearning previously learned information and activities (e.g., using a razor).
- EF was examined and found to be very confused about social norms (e.g., appropriate attire outside his home). EF exhibited memory loss of his personal experiences (e.g., childhood), and the impaired ability to recognize his wife and parents.
- JG is the first recorded patient suffering from isolated RA.
- GH, a mother and a wife, had surgery in August 2002. When GH woke up after the surgery, she believed it was May 1989. Due to her amnesia, GH experienced great difficulty in her social environment, being overwhelmed by relationships to others.
Although it may seem that people living with brain damage have great difficulty continuing the usual day-to-day aspects, they still can accomplish many feats. People with RA are able to lead a normal life. For instance, KC is a man who has many functional aspects intact; normal intelligence, unaffected perceptual and linguistic skills, short-term memory, social skills, and reasoning abilities. All of these things are necessary in everyday life and contribute to normal living. KC also is fully capable of scripted activities (e.g., making reservations or changing a flat tire). In addition, patient HC successfully graduated high school and continued into post-secondary studies, an obvious accomplishment despite her condition.

Famous quotes containing the words case and/or studies:
“In my youth, said his father, I took to the law,
And argued each case with my wife;
And the muscular strength, which it gave to my jaw,
Has lasted the rest of my life.”
—Lewis Carroll [Charles Lutwidge Dodgson] (18321898)
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)
