Heterogeneity

Alcoholism and overeating are heterogenous disorders in that individuals engage in these behaviors for a variety of reasons, both behavioral and neurochemical.

We are currently involved in a series of studies investigating not just how neuropeptides can lead individuals to binge on alcohol or overeat, but how they may do this differently in different individuals.

Individuals who drink excess alcohol due to their poor metabolism show different neuropeptide disturbances than those who drink due to their preference for novelty.
