A mathematical model for evolution of human functional disorders influenced by environment factors

A mathematical model predicting the evolution of human functional disorders under environment influence is developed. The natural aging, regeneration processes, accumulation of damage due to abnormal substances streams and functional recovery through treatment are considered. Inflow of substances from the environment, accumulation, metabolism and elimination are described with neuro-humoral regulation. Numerical solution of differential equations based on implementation of finite difference schemes are obtained for different cases.
