Here is a relevant excerpt on this very topic from one of my articles that I had to delete for space considerations. I can provide references in case anyone needs them. According to Dalton and Hardcastle, both in Great Britain (1993), and St. Louis and Myers (1997), pure cluttering appears to be rare. In contrast, Froeschels (1946) stated that significant numbers of children with cluttering are enrolled in the speech clinics of public schools. Generally, the literature indicates that cluttering is less prevalent than stuttering (Daly & Burnett,1999; St. Louis, Raphael, Myers, & Bakker, 2003). Simkins in USA (1973) estimated that, in all probability, 11.5 percent of the children attending special education classes were probably clutterers. Becker and Grundmann (1971) established that 1.8 percent of 7- and 8- year olds in a German school manifested cluttering. Miyamoto and Hayasaka in Japan, and Shapiro in USA (2006), in a study of special classes for 208 students between 6—12 years of age, with speech and language disorders, 1 percent were diagnosed with cluttering, and 14.9% were diagnosed with cluttering-stuttering. Preus (1981) reported that, in Norway, 32 percent of adolescents who stuttered also cluttered. Van Borsel & Vandermeulen, both in Belgium (2008) reported 78.9 percent of children with Down syndrome were diagnosed with cluttering, and 17.1 percent were classified as a clutterer-stutterer. In Russia, Shklovsky (1994) reported that 10 percent of clients with stuttering who entered their clinic were diagnosed with cluttering. More recently, Filatova in Russia (2002) found that, out of 55 Russian children with fluency disorders, 7 percent were pure clutterers; 13 percent had a mixed form of disorder, with prevalence of cluttering. Missulovin in Russia (2002) described cases of cluttering in patients who stutter due to organic cerebral insufficiency. In a survey by Missulovin (2002), among stutterers due to organic cerebral insufficiency, cluttering numbers varied depending on age. Specifically, 48 percent had cluttering between the ages of 12 and 14; 38 percent of adolescents between 15 and 17 also cluttered; as did 31 percent of the adults between ages 18 and 53. In the USA, Freund (1952) found that, of people who stutter, 22 percent also cluttered; and in a later study (1970) of 50 cases of neuro-psychiatric patients with tachylalia, 10 percent also cluttered. Daly (1993) found that in his caseload about 5 percent of clients with fluency disorders had pure cluttering and 40 percent were clients with cluttering and stuttering.Some experts believe that the incidence of cluttering tends to be underestimated because many people with cluttering do not seek speech therapy or consider cluttering to be a minor disorder ((St. Louis, Myers, Bakker & Raphael, 2000; Ward,2006; and Simkins, 1973).
