My name is Antonio P.
Strafella, and I'm a
professor of neurology at
the University of Toronto.
The topic of my
presentation today will
be on the impulse
control disorders and
dopamine dysfunction
in Parkinson disease.

These are my disclosures
and I don't have
any specific commercial interest
in relation to my presentation.
0:25
The objective of today's
presentation will be to
describe the role of dopamine
in behavioral complications
in Parkinson's disease.
To describe as well how
neuroimaging is helping
us to understand
these complications and to
describe receptor abnormalities
and neural network
changes involved
with these behavioral complications
in Parkinson's disease.
0:56
The recent developments
in the field
of molecular imaging
is allowing us
to investigate new
frontiers in the field
of Parkinson disease in
atypical Parkinson's disease.
Today, in our research center,
we are able to image different
neurotransmitters in
the structures of the brain
involving the
dopaminergic system,
but also as well, the
serotonergic system and
the cholinergic system.
To image these different
networks in our brain,
we have at our disposal
presynaptic and
postsynaptic radiotracers
as potential biomarkers.
The focus, of course,
today will be mostly
on those imaging
biomarkers for the
dopaminergic system.
