New Cognitive
Disorder Treatment Possible
(May 3, 2007) -- U.S. scientists have identified a new class of compounds
that could be used in drugs to treat various cognitive disorders.
University of California-Irvine researchers said the compounds target
receptors in the brain that are activated by nicotine, imparting the
beneficial effects of nicotine -- specifically enhanced cognition -- but
without health threats associated with smoking.
"We'd like to see this lead to a drug that would address specifically the
cognitive deficits found in
schizophrenia," said Profesor Kelvin Gee. "We could probably treat more
schizophrenics on an outpatient basis and allow them to
re-enter mainstream society if we could address cognition."
The three-year animal study showed activating a certain nicotinic
receptor in the brain improved working memory and made it easier to
filter sensory input.
The study -- which also involved researchers Herman Ng, Edward Whittemore,
Minhtam Tran, Derk Hogenkamp, Ron Broide and Timothy Johnstone, all of UCI;
and Lijun Zhang and Karen Stevens at the University of Colorado -- appears
in the online edition of the Proceedings of the National Academy of
Sciences.
