Is there an impatience genotype leading to non-adherence to long-term therapies?

In chronic diseases such as diabetes, adherence to therapy aims to preserve health, which is a long-term objective, whereas non-adherence tends to present an immediate 'reward'. We propose that non-adherence, like addiction, is at least in part due to the fact that, for physiological, and maybe genetic reasons described in a new field, neuroeconomics, a number of people have a taste for the present rather than the future. Thus, for 'impatient patients' it is natural not to adhere to therapeutic prescriptions that share the characteristic of being future-oriented. This hypothesis may apply to any disease requiring long-term therapy.
