Can the cingulate gryus suppress the pre-frontal cortex?

 I have lived a life of high anxiety and ongoing cognitive problems (foggy 
brain / memory issues / difficulty with concentration) whilst paradoxically 
still achieving above average scores on IQ tests.

The cognitive difficulties have caused me such frustration that I have 
undergone a series of SPECT scans in an attempt to find what, if any 
biological condition may be causing this. A diagnosis based upon the SPECT 
results and historical mood data came back with the probably that I suffer 
from Bipolar II and an extreme obsessive generalized anxiety disorder.

The SPECT results have shown normal metabolic function through the majority 
of the brain, however a grossly overactive anterior cingulate gyrus was 
noted. A scan such as this is synonymous with obsessive anxiety conditions.

For anybody who may have some technical knowledge in the background, could I 
be correct in supposing that an overactive cingulate gyrus may be 
suppressing signals from reaching the prefrontal cortex / executive seat, 
and thus causing me the attentional and cognitive difficulties that I have 
been experiencing?
