abstract = {Down syndrome (DS) is a common genetic cause of
intellectual disability yet no pro-cognitive drug therapies
are approved for human use. Mechanistic studies in a mouse
model of DS (Ts65Dn mice) demonstrate that impaired
cognitive function is due to excessive neuronal inhibitory
tone. These deficits are normalized by chronic, short-term
low doses of GABAA receptor (GABAAR) antagonists in adult
animals, but none of the compounds investigated are approved
for human use. We explored the therapeutic potential of
flumazenil (FLUM), a GABAAR antagonist working at the
benzodiazepine binding site that has FDA approval. Long-term
memory was assessed by the Novel Object Recognition (NOR)
testing in Ts65Dn mice after acute or short-term chronic
treatment with FLUM. Short-term, low, chronic dose regimens
of FLUM elicit long-lasting (>1week) normalization of
cognitive function in both young and aged mice. FLUM at low
dosages produces long lasting cognitive improvements and has
the potential of fulfilling an unmet therapeutic need in
DS.},
