Research reveals drug targets for memory enhancement

Loss of memory is a core feature of many neurological and psychiatric disorders including Alzheimer's disease and schizophrenia. Current treatment options for memory loss are very limited and the search for safe and effective drug therapies has, until now, had limited success.

The research was done in collaboration with colleagues at the international biopharmaceutical company Sosei Heptares. The findings, published in Nature Communications, identify specific receptors for the neurotransmitter acetylcholine that re-route information flowing through memory circuits in the hippocampus. Acetylcholine is released in the brain during learning and is critical for the acquisition of new memories. Until now, the only effective treatment for the symptoms of cognitive or memory impairment seen in diseases such as Alzheimer's is using drugs that broadly boost acetylcholine. However, this leads to multiple adverse side effects. The discovery of specific receptor targets that have the potential to provide the positive effects whilst avoiding the negative ones is promising.
