Brain imaging for Schizophrenia - Not There Yet
Read more... Schizophrenia Diagnosis
The New York Times had a good article this past weekend on how research in brain imaging has been in development for quite a number of years, and is helping scientists understand brain disorders at new and better levels. This research, however, is not yet ready for clinical applications that would start helping people directly (for example in diagnosis) because the "resolution" of the imaging technology is not to the level that it needs to be, and costs are high. The good news is that research in many other areas are showing significant results (read about other new diagnosis tools)
The New York Times notes:
Not long ago, scientists predicted that these images, produced by sophisticated brain-scanning techniques, would help cut through the mystery of mental illness, revealing clear brain abnormalities and allowing doctors to better diagnose and treat a wide variety of disorders. And nearly every week, it seems, imaging researchers announce another finding, a potential key to understanding depression, attention deficit disorder, anxiety.
With regard to schizophrenia, specifically, the story notes:
In a range of studies, researchers have found that people with schizophrenia suffer a progressive loss of their brain cells: a 20-year-old who develops the disorder, for example, might lose 5 percent to 10 percent of overall brain volume over the next decade, studies suggest.
