Cognitive impairment is a dramatically increasing problem affecting many individuals as well as the health system. As we have no causal treatment for the loss of memory, symptomatic treatment is needed. Influencing the ACh system is a generally accepted approach, although other therapeutic treatments are in various stages of development. The multiple target drug approach using hybrid compounds may be another optimized move forward for the treatment of cognitive disorders. Since the complex neuronal regulation is slowly being decoded, there is hope that ways will be found to stop neuronal loss and to generate new synapses.
