Pharmacotherapy for cognitive impairment in a mouse model of Down syndrome

Ts65Dn mice, a model for Down syndrome, have excessive inhibition in the dentate gyrus, a condition that could compromise synaptic plasticity and mnemonic processing. We show that chronic systemic treatment of these mice with GABAA antagonists at non-epileptic doses causes a persistent post-drug recovery of cognition and long-term potentiation.
