Paul (and anyone else interested),
I'm no doctor, but I am working on a degree in Neuroscience.
The symptoms you described - fatigue, mem. loss, concentration problems -
are all due to ATP depletion, as a previous posting said. The reason the
symptoms are so varied is due to the way that ATP works. The fatigue is
probably not neural, but muscular. ATP is essentially "energy currency"
for the body - the high energy phosphate bonds store (and later release)
energy as it is needed. With deficient ATP, your muscles have less available
energy. The other symptoms are due not to ATP itself, but a form of adenosine
called cyclic AMP (aden. monophosphate). cAMP is used as a second messenger
in neurons. In other words, it relays and amplifies signals sent to neurons by
neuro-
transmitters. If there isn't enough ATP to transform into cAMP, some types of
neurons don't work very efficiently. Memory and concentration to some degree
are
controlled through the Hippocampus. Low cAMP here would cause your symptoms.
As that previous posting said, not having enough of the ATP precursor adenosine
seems to be the problem. I don't know enough about CoEnz. Q10 or Gingko
products
to tell you why they make you feel worse, but chances are there are alkaloids or
glycosides
present in the compounds which inhibited the conversion of adenosine to cAMP. A
physiologist or clinician would be better help, but I hope this helps clear
things up a bit.
