This is very interesting. “This suggests that while
healthy people recruit a specialized and focused network of brain areas for
specific memory functions, schizophrenic patients seem to rely on a more
diffuse and wider network to achieve the same goal. The researchers also found
a fundamental difference in the way healthy people and schizophrenic patients
made errors. When healthy people forgot,
they had no confidence in their response for that trial and the brain areas that
were recruited during correct memory trials remained inactive. A more complex picture emerged for
schizophrenic patients. When healthy
people are correct, there is an increased activation of the right frontal
cortex. When they forget, there is no
such increase. Their brain activation
pattern is tightly coupled with their memory performance. Not so with schizophrenic patients,” Park
said. My memory for numbers is great.
For other things I just keep reminding myself that I have to do
something. Or remember something. I do
not know how I would do on a test like that.
The article says: “Schizophrenic patients may encode and remember incorrect information. The brain activation pattern during such error trials indicates that indeed they were remembering something. Albeit incorrect,” she continued “Such coupling of storing incorrect information and feeling confident of one’s response may be one way to think about how delusions get initiated,” Park said. “Researchers have known since the early 1990s that working memory problems are a consistent symptom of schizophrenia. The researchers sought to better understand what is occurring in the brain that may be causing these problems. The right hemisphere is usually recruited during spatial information processing but if it is malfunctioning, as it may be in schizophrenia, the left hemisphere may also be recruited,” Park said.” The brain is not processing right. You believe something is true and then you have a delusion.
They did tests to figure this out. “Another possible explanation is that schizophrenic patients may have more difficulty with these tasks, and as a result recruit more brain areas to assist them. In the experiment, the subjects were shown a point on a computer screen and told to concentrate upon it. Three identical black circles were then flashed on a gray background, each in a different location. After a short delay, the subjects were shown a probe and told to press one key if the probe matched one of the circles show earlier and another if it did not. They then were told to press another key ranking on a scale from one to five their confidence in their answer about the probe. The researchers captured images of brain activity during these tasks using functional magnetic resonance imaging, or MRI. They repeated the experiment to capture data using another tool, near infrared spectroscopy, or NIRS. NIRS is a new and promising way to study schizophrenia, the researchers believe.” I hope this works so they can find ways to help people with schizophrenia. We all could use our memory. It is something that worries me about growing old what problems will I also develop? Or is schizophrenia my only problem in life?
