    I am a bit confused. I am COMT V158M ++, COMT H62H ++ and COMT P199P +-, which means I don't break down dopamine very well, nor to I break down cortisol well. That would mean I would tend to have more of each circulating, and therefore would tend to have higher motivation. But I don't.

    Am I incorrect in my assumption that COMT ++ leads to more circulating dopamine leads to higher motivation and other dopamine characteristics? I definitely seem to be more sensitive to pain than other people.

    Hi Pam

    I believe COMT metabolises dopamine (breaking it down for recycling and reuse) so the low activity met/met allele of COMT V158M would mean that you don't process dopamine effectively which would mean dopamine signalling is impaired.

    This has known implications re stress, executive function and pain sensitivity.

    You might find my series of blogs of interest as COMT figures several times :

    “ the Val(158)Met polymorphism in COMT is associated with obsessive-compulsive disorder in men, with anxiety phenotypes in women, and has a greater impact on cognitive function in boys than girls”

    Hi Pam - if you're still around.

    Essentially yes. As regards Val158Met, if you're not breaking down and recycling dopamine efficiently then dopamine transmission will be impaired.

    Thanks, Marco -- that explains so much. Do you have any suggestions as to what to do to make dopamine transmission more efficient?

    Nope - not off the top of my head. Its a genetic trait unfortunately.
