I recall the case of a certain young man who had depended upon his own knowledge to determine the identity of his speech defect and the nature of his trouble. When a boy, he had swallowed a small program pencil with a metal tip, injuring his vocal cords, so he said, and causing him to become a stammerer. An examination of his condition and a careful diagnosis of his case revealed the fact that his vocal organs were as normal as those of any person who had never stammered. The diagnosis also revealed the fact that his stammering was not originally caused by any organic defect or any injury to the vocal organs, but that, on the other hand, he had, in the first place, inherited a predisposition to stammer, his father and his grandfather both having been stammerers whose trouble had never been remedied. The diagnosis showed that the onset of the trouble immediately after swallowing the pencil was due chiefly to the nervous shock and fright caused by the accident, which, in conjunction, with the inherited predisposition toward stammering, was too much for the boy's mental control and he immediately developed into a stammerer. The young man had believed for many years that his defective utterance was totally incurable, that it was due to an organic defect which could not be remedied. The diagnosis quickly revealed, however, that a very different condition was responsible for his trouble and as a consequence, he found himself able to be cured where, without expert diagnosis, he had resigned himself to a life as a stammerer. Another case which also shows the stammerer's inability to diagnose his own trouble accurately was that of a woman who persistently refused to allow her son to have his case diagnosed, because of her belief that he was incurable and that the diagnosis would be a waste of time and money. After months of coaxing, however, he succeeded in getting her to consent and I gave him a thorough diagnosis and report on his condition. This mother had been unduly alarmed--the boy was still in a curable stage and in fact completed the necessary work in much less than the usual time. This is but another case that shows the loss which comes from not knowing the truth. Written Report of Diagnosis Valuable: It is well to get a personal diagnosis of the case where possible, but if this cannot be done, a written history of the case, together with a statement of the symptoms and present condition, should enable the expert diagnostician of speech defects to make a thorough and reliable diagnosis of the trouble. This diagnosis, to be of the most value to the stammerer or stutterer, should be made up in the form of a written report, so that the information may be in permanent form and so that the sufferer can study his own case in all its angles.
