Germ-line mutations are often at least in part the cause of disease<unk>  at an earlier<unk> . Though many germ-line mutations are deleterious, the genetic lens through which they may be viewed may provide insights to treatment, possibly through genetic counseling. In some cases, the<unk>  may be the result of mutation accumulation. If this is the case, it could be helpful to consider<unk>  as a product of the hypotheses depicted in theories of aging. Even some mental health disorders, whose<unk>  have been found to be harder to define than physical illnesses may have a mutated component. The symptoms of standard mental disorders often start off non-specific. Pathological changes pertaining to disorders often become more detailed and less fickle before they can be defined in the American Psychiatric Association's DSM. The brain is a dynamic and complex system, it is constantly re-wiring itself and a major concern is what happens to the brain in earlier life that mirrors what occurs later in its psycho-pathological state. The typical<unk>  of many mental disorders in late adolescence may reflect the critical development that happens at this time.
