The nervous system is relatively easily damaged, but it takes much longer to heal than other tissues. Better prognosis and faster rehabilitation can be achieved by stimulating the synthesis of the brain and peripheral nervous system's own biologically active substances. Special therapy schemes and the addition of short peptides help in this. In my observation, brain peptides reduce the risk of severe nervous system disorders in chronic stress, as well as in people who have a lot of mental work. In old age, combined with other methods, they help maintain cognitive function.
