Some will think 'lack of blood flow' means no blood flow. A more accurate definition of hypoperfusion is low blood flow. I have seen people over-react many times to comments from doctors. I could not tell what you were understanding. You have made some comments that appear to take an extreme definition of a concept. This is common with PCS.

You still have not explained what treatments have been suggested for either, hypo or hyperperfusion.

CognitiveFX in Utah claims to have therapies to resolve hypoperfusion but they start their program at $5000 and up, usually $7000 to $10,000. Their claims have not been substantiated by any outside sources.

HBOT takes 40 dives (treatments) or more to start to see a difference if it makes a difference. Dr Harch is still doing his study and has not published any results.

Low Level Laser Light Therapy does not reach beyond the first centimeter or two so affecting deep brain tissue is difficult.

If the neuro could explain what part of your brain has hypo and what processes activate those areas, you could do exercises to encourage blood to those areas. That is basically what CogFX does.

Try to keep in mind that increasing perfusion in the hypo areas may not make any difference. That hypoperfusion could have pre-existed your injury. Many who have SPECT and PET scans find abnormalities that do not relate to symptoms. I have abnormalities in my SPECT that do not relate to any symptoms and my symptoms do not show as any imaging abnormalities.

This is the frustrating part of imaging and PCS. A good qEEG read by an expert in concussions can be more informative but those experts are hard to find. My qEEG expert died last year. He was a pioneer.

btw, Omega 3 oil thins the blood and should allow blood into smaller vessels.
