Biologically, plausible treatment strategies include the use of antidepressants (selective serotonin reuptake inhibitors or serotonin-specific reuptake inhibitor and monoamine oxidase inhibitors), acetylcholinesterase inhibitors, N-methyl-D-aspartic acid antagonists, mood stabilizers, antipsychotics, stimulants, antihypertensives, and agents that may ameliorate the symptoms of parkinsonism, pseudobulbar affect, and motor neuron disease that can often coexist with FTD.
After establishing that Paraoxon-induced AChE inhibition indeed aggravates experimental Parkinsonism triggered by the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in mice, we tested the roles of individual AChE variants by exposing transgenic mice overexpressing either the AChE-S or AChE-R variant to MPTP.
