The first is what you've experienced with the tree bump. It usually takes me 2-3 weeks to slowly climb the "heart rate" ladder but I always eventually get there. Once "there", I can tolerate rates up to 160 bpm. In other words there is eventually no limitation from a purely cardio perspective.
The second problem I have (which has never really improved) is an inability to tolerate higher levels of resistance in the exercise (such as weight training, high resistance to pedaling, etc). When I push the limit, I develop i head pain which lingers for a while. If I "really" push the limit, I feel cognitively hazy for a while. I can provoke this pain without raising my heart rate or moving my neck (for example squeezing something tightly). When I bump my head, the tolerated "strain threshold" decreases for a few weeks much like the heart rate issue. However even after I'm finally able to tolerate higher heart rates, I never fully improve on the other stuff. I continue to hunt for explanations regarding the physiological changes induced by the mTBI. I too will be interested in hearing how things went with Dr Leddy. Keep us posted.

So I think the cognitive haze CAN be explained by upper cervical neck injury. If the blood flow is compromised from injury that is exacerbated by exertion you would feel mental fog etc.
I passed the physiological PCS test at buffalo. They think my symptoms stem from a combo of vision issues and neck issues. Doesn't totally explain the head bump relapse or why higher heart rate exercise does SEEM to bring worse symptoms but then again I can get dizzy from a slow walk around my neighborhood or a trip to the super market (visual input overload). As for my exercise regime still don't know what to do. Was doing recumbent bike in heart rate of 130s and 140s with varying degrees of symptoms that I can't pinpoint to specific causes. I have a high heart rate by the way so 130s is my recovery zone! I'm not even aerobic at that.
Was happy to find I tolerated some push-ups and air squats with no brain symptoms. Overall from my visit to the clinic feel like I got some answers - first doc who said i needed a vestibular consult, since my balance has been fine i was never previously referred- but the answers seem to have only prompted more questions....
It sounds like you may also have some neck issues ...don't give up asking questions because if we don't keep at this hunt we will never get answers...
