Bad circulation in the head

Been knocked down by the cold for almost a week.  So I went to see my uncle the doctor who's been treating me since a kid.

He showed me a picture of my inner ear with blood vessels readily visible and explained to me that the reason why the vessels could be seen so clearly might have something to do with bad circulation.

The matter of the fact, I had always know that my blood circulation was no good since a kid with them cold feet.  Yet, the circulation department get even worst after the accident in 2007 and even worst in January 2011 after the body got broken again.

Yet, so say the experts... the pattern of the brain blood flow in schizophrenic patients are different than that of the normal.  For instance, as per RSNA press release: Blood Flows Differently Through the Brains of Schizophrenic Patients

"... compared to the healthy controls, the schizophrenic patients had extensive areas of hypoperfusion, or lower blood flow than normal in the frontal lobes and frontal cortex, anterior and medial cingulate gyri, and parietal lobes. These regions are associated with a number of higher cognitive functions including planning, decision making, judgment and impulse control.
Hyperperfusion, or increased blood flow, was observed in the cerebellum, brainstem and thalamus of the schizophrenic patients."

At the same time, existing research has also found abnormal brain blood flow pattern in patients with chronic pain.  For instance, in the article Brain perfusion abnormality in patients with chronic pain, the authors found:

"....decreased cerebral blood flow was observed in the dorsolateral prefrontal area (both sides, right dominant), medial (both sides), dorsal aspect of the anterior cingulate gyrus ociceptive cortex and lateral orbitofrontal cortex (right side).

So I thought.... good lord...

What might have contributed to the observation of my bad circulation in the head?  While, to be honest, how does it matter for me?  8-O lol
