Stage 2 consists of shorter and less frequent therapy sessions with self-help and family assisted home therapy. Results have shown that people learn the process within the three-week period of the first stage. Some patients also testified that through this program, they were able to understand their difficulty in speaking. In rare cases, lesions or structural flaws in the part of the brain that takes charge of a person s motor speech trigger this neurogenic condition. Psychogenic Disorder Scientists explain that some forms of stammering originate from the brain s activities such as reasoning and thought. This type of stammering is called psychogenic disorder. Some drugs are prescribed to cure the symptom of stuttering rather than the underlying etiology. For instance, neostignine was used because it was effective in treating spastic conditions, which some studies consider stuttering as a form of spasm. Luckily, some experiments showed positive results. In addition, verapamil is a drug prescribed due to serendipitous basis a calcium channel blocker is used in treating cardiac arrhythmia. Depending on the progress of patients, treatment sessions are normally reduced to once a week and then to once every other week, to once a month until the termination of treatment. The first concern of the treatment program is patients use of cognitive secondary mannerisms. This process focuses on elimination of the use of avoidances, substitutions, and circumlocutions. You don t need to worry because this is only normal, but if the case is already causing problems, like the child feels intimidated in talking to other people or they are exhibiting such for more than six months already, this is the time when you can seek doctor s help. Out of all cases, only 1% of these children will continue to carry this kind of problem until they get older. Many researchers have come out with varied results some psychological basis and others neurological causes. There is another field that says stuttering is a homogenous disorder but this is yet to be disputed. It says that stutterers suffer from one underlying problem. Nevertheless, popular theories are based on heterogeneity of the disorder.
