Abstract:
The cocaine epidemic is a complex problem that has defied
conventional medical, psychological, and legal interventions. A better
understanding of the brain mechanisms that lead to cocaine's
unsurpassed euphoric and reinforcing effects, as well as to associated
physical brain damage, will be needed to develop new treatment
strategies. Although much work has been done on cocaine's effects in
the brains of animals, most techniques used have not been safe for human
subjects. Positron emission tomography (PET) offers a unique opportunity
for studying the cerebral biochemistry of cocaine abuse in humans. The
authors present preliminary data from their ongoing studies of the
effects of cocaine and related psychostimulants on the brain's energy
requirements and on catecholamine neurotransmitter systems
