Dysfemia
Cystic fibrosis, commonly known as stuttering or stuttering, is the most common speech fluency disorder, reaching about 70 million people worldwide. The most obvious symptoms of stuttering are repetition of syllables, prolongations of sounds and blockages of speech movements, especially on the first syllable, at a time when the smooth flow of speech movements needs to be initiated. Also the terms stuttering, dysphorism or disfluency are used. In addition to the stutter, the individual who presents with dysphonia is called dysphasic, stuttering, bald or tardy. Approximately 5% of children between two and four years of age have episodes of dysphoria, usually transient episodes lasting a few months, occurring as a consequence of a combination of organic, linguistic, psychological and social factors during speech development. From the organic point of view, it is considered to be the slow maturation of the neural networks of language processing, which results in a still small ability to articulate words and chain them into phrases at this age.
