Guest guest Posted May 6, 2005 Report Share Posted May 6, 2005 , thanks for these new links to neuroBb articles. An offer to you and any one else here for help with interpretation of such papers or other information re: Bb & neuro stuff -- have a lot of experience with both and have given a few talks on these topics. My PhD is in cognitive neuroscience (basically, I deal with the various brain regions and their functions for different cognitive activities), have been doing research for over 20 years (man, I don't feel old enough to say something like that!) and my speciality area is human memory. Many of my subjects in the past have likely been constipated. :') > April 2005, hot off the press... > > Arch Neurol. 2005 Apr;62(4):671-3.

Guest guest Posted May 7, 2005 Report Share Posted May 7, 2005 I sent you an email, cuz I'm craving some off-list contact with that astonishing brain of yours. But there is something I would like to ask you here. Until this illness, I assumed as most people do that if my brain was in trouble I would lose the higher functions first. But my symptoms, my cognitive impairments, and the objective findings on my brain MRI all tell a story that runs in the other direction. Can you give us a sort of basic primer on the variations in cognitive decline? That may be an impossible task, but if so tell me and I'll try to refine the request.

For example, Alzheimer's, one example of cognitive decline, shows atrophy first in the hippocampus (limbic system, think " lizard brain area " ) along with the entorhinal cortex (brain area around the hippocampus, then the entire temporal lobe tends to get involved along with the parietal lobe. Frontal lobe is actually late to the game even though that is last on the evolutionary scale and is key for higher-level things like planning and setting cognitive agendas. My recollection of SPECT stuff in Bb is that the hippocampus and adjacent temporal structures also show up as hit most frequently (when the result isn't simply global, diffuse hypoperfusion). Also, in general, the hippocampal area is most sensitive to oxygen deprivation. All this to say that the hippocampus, while amongst the oldest structures evolutionarily speaking, is also amongst the most delicate & sensitive when it comes to various biological insults (You seahorse you!). BTW, probably not suprising to anyone here, the hippocampus is a crucial structure in some of the most basic memory processes in which we engage. In short, cognitive decline is hardly ever a neat backwards romp down functional evolution lane. Cognitive decline critically depends uppn the brain areas involved in whatever biological process is taking place. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted May 8, 2005 Report Share Posted May 8, 2005 Yes...I'm afraid this is more or less a description of the objective findings about my brain. Which helps me to understand why they want to rule out Alzheimer's. DM, I was suprised to find that the use of PET scans for differential diagnosis between Lyme and Alzheimers was regarded as something 'new' by the hospital I called to schedule the test. What the hell have they been doing with Alzheimers, just telling people to get ready for DroolsVille Manor? I dunno, I think my brain is trying to outwit the bugs. I guess that sounds crazy, but I really sometimes think I can feel adjustments trying to happen, like how the vertigo or the flickers and white- outs in my peripheral vision will flare up, longer each time, but then they subside. Maybe my brain is figuring out how to stop the little vermin from completely screwing up my awareness. Brain parasites - am I the only one who gets the heavy duty sci-fi flavor of that, I mean really, there needs to be a movie where the damn things are from outerspace and it turns out Borreliosis is a higher form of consciousness. Well, maybe not. It thrills me that we have you on I & I, DM.
