Guest guest Posted August 2, 2001 Report Share Posted August 2, 2001 Thanks Sherril! Maybe I'll see you Monday at our next CHERAB meeting, and we can talk live! (wasn't the conference great?!!) I know that stuttering is normal in Tanner's age range (he only just turned 5 in June) I'm wondering out loud if it's possible that there can be two types of stuttering. Is it possible that there is any correlations at all between apraxia and stuttering? And since stuttering is common, for apraxic and non apraxic children, why is there such mixed information/opinions out there on how to treat an apraxic child who enters the stuttering stage? Here is an interesting article about stuttering that Rhonda from the Canadian ECHO group sent me a few months ago that I meant to send out with my post yesterday. I thought it's worth sending out still, and maybe you (and others) will find this of interest. " STUTTERING Can Stuttering be cut short? by Helen Buttery, the National Post Can stuttering be cut short? New insights into how the brain processes speech may provide answers Helen Buttery National Post Fox Broadcasting Jim Rowlett found his stuttering dropped off after three weeks of intensive therapy. While he was growing up in the 1960s in northern Manitoba, Jim Row- lett's parents were told, " He thinks faster than he can talk, he'll grow out of it. " But he didn't, and for the first 30 years of his life stuttering controlled almost every decision he made. He wanted to be an RCMP officer, but in Grade 12 Rowlett realized, " I'd have to talk and I wouldn't be able to. " So instead he chose power engineering, which involves boilers and pressure vessels. " Boilers and equipment don't talk, " he says. Not only did stuttering direct the big choices in his life, it also monopolized the small ones. Instead of asking for food he craved on a menu, he would order what he could pronounce. His biggest fear was the telephone. He would drive miles across town to see if a shop had a part that he needed rather than call for the information. Rowlett is among 300,000 Canadians who suffer from stuttering. No one knows what causes it, but developments in brain-related technology are helping researchers understand how it works. Eventually, this should lead to better treatments. " Technology has driven the interest, " says Ingham, professor of speech and hearing sciences at the University of California in Santa Barbara. " With the development of PET [Positron-Emission Tomography] technology we've been able to get a much better picture of the neuro- processes associated with speech than we could ever have done before. We're now asking questions we couldn't ask before. " The idea that there is a link between stuttering and the brain first appeared in the 1920s. Building on discoveries linking the left side of the brain to speech, it was hypothesized that stuttering was caused by a lack of left-brain dominance, and that this was somehow linked to handedness. Children were made to write with their right hands to stimulate proper development of the speech centres of the left side of the brain. It didn't work and, with no means to test this notion, it was brushed aside until recently. Now, scientists have confirmed the left side of the brain dominates people's speech centres, but for a small percentage of the population -- less than 5% -- speech is processed using both sides of the brain. Among left-handed people this percentage is higher, an estimated 30%. But left-handed stutterers will not improve their speech by writing with the right hand. Handedness does not play a role in stuttering, but how the brain processes speech, laterally or bilaterally, does. Three groups in North America (at the University of Toronto, the National Institutes of Health in Washington, and the University of Texas in San ) are trying to locate regions in the brain crucial to the presence or absence of stuttering. The group in Toronto, including Luc De Nil, a speech pathologist at the University of Toronto, compared the brains of 10 stutterers with the brains of 10 non-stutterers while they performed several tasks. The stutterers were then asked to repeat the tests after three weeks of intensive speech therapy, to see if this influenced the brain's activity. The findings were published last summer in the Journal of Speech, Language, and Hearing Research. Both groups were asked to read words on a screen, first silently and then aloud. For the non-stuttering subjects, as expected, brain activity occurred during both activities, in the left hemisphere of the brain and in the Broca's area (the left frontal lobe of the brain, responsible for speech production). The stutterers, however, showed an increase in activity throughout the brain, including the right hemisphere. " There is no clear right- left correlation, " says De Nil. The stutterers " were invoking many different regions of the brain that are typically not involved [in the speech of] non-stuttering subjects. " During the silent reading, these areas were called upon to a lesser degree, but they were still active. One of these regions is the cerebellum. Located at the back of the brain, it co-ordinates movements of large muscles in voluntary motion. " If you are learning a new motor task or new movement, [the cerebellum] is highly involved in error correction, " says De Nil. For example, if you pick up a tennis racket for the first time, it will take time and practice before you perfect your backhand. The cerebellum will be activated to adjust your movement and speed until it becomes a smooth, involuntary movement. Once this is accomplished, the cerebellum's activity will significantly decrease. The involvement of the cerebellum in the speech process of people who stutter indicated to De Nil " that even saying those very simple words, for stuttering subjects, is not automatic. " Another unexpected area involved in the speech of stutterers is the anterior cingulate cortex (ACC). This usually comes into play when people perform cognitive tasks requiring concentration. " We didn't see activation in our normal speakers, but in our stutterers it was one of our most highly activated areas, " says De Nil. The final task required the subjects to say an action word or verb associated with the word on the screen. For example, " chair " might invoke " sit. " " When we look at just the verb generation task, we found no differences between our stutterers and non-stutterers, " says De Nil. The verb generation task, unlike the two previous exercises, was a cognitive test, where both test groups had to come up with a word. This indicates that where the stutterers differ from the non- stutterers is at the level of controlling the movement of the tongue, jaws and lips. " It's not that they have difficulty coming up with the words ... it's more the control of the physical movement that seems to create difficulty, " says De Nil. This physical movement originates in the brain. " This has strengthened the idea that stuttering has a neurological foundation. It is not a psychological problem. People do not stutter because they are nervous. " Although treatment for stuttering has been available for more than 20 years, speech pathologists are only now seeing how the brain responds to therapy. Rowlett has experienced this help first-hand. With his 30th birthday approaching, he realized his problem was not going away. He decided to take a three-week therapy program at Edmonton's Institute for Stuttering Treatment and Research, telling everyone he was going on vacation in case it didn't work. " You are literally in therapy for eight hours a day, five days a week. They teach you a whole new way of forming your words, " says Rowlett. This is similar to the treatment used with the subjects in the Toronto study. De Nil compares the process to learning to type with all fingers when you have spent years typing with only one. " You're not going to start typing at 60 words a minute. We're going to start very slowly. " Stuttering, like other developmental disorders such as dyslexia and Tourette's syndrome, are genetic and sex-linked. Boys are three times more likely to stutter than girls. Rowlett probably inherited the trait; his uncle stuttered. Signs of improvement came quickly for Rowlett. After the first week of therapy the group went to a bar. He had always wanted to order a Labatt's Blue, but his stuttering prevented him. When the waiter asked what he wanted, he said, " I'll have a Labatt's Blue, " and his eyes welled up with tears. " This was the first time I could actually order a Labatt's Blue, " he says. After treatment, the stuttering subjects in De Nil's study show reduced overactivation across the whole brain. " Still, it's not highly automatic, they have to think about what they're doing when they're speaking, " he says. Therapy is very effective for most stutterers, especially children whose systems are more susceptible to change. " Their brains are much more plastic, more malleable, " says De Nil. It is not unusual for children to stutter, especially between the ages of 2 and 5. Most will outgrow the problem. " One of the words I have trouble with is 'three,' and sometimes the 'S' sounds get away from me. But overall, I'm in charge of it now, " says Rowlett. The Toronto studies have shown how the brains of stutterers behave, and how therapy can change the way the brain functions, but researchers still do not know exactly how the brain adjusts itself. Where is the switch turning these areas on and off? The research lab in San hopes to shed some light on this. Scientists there have discovered that the same parts of the brain are activated in people who stutter whether they are reading aloud or reading silently while imagining that they are stuttering. The findings were published in the November issue of the journal Brain and Language. " [stuttering occurs] in the pre-planning phase of speech, before you actually open your mouth, before the utterance occurs. It's independent of speech, and it's almost as though the neuro-system is present to produce the problematic behaviour, " says Ingham, who worked on the study in Texas. The investigation found the auditory association area (part of the temporal lobe located near the skull above and behind the ear) is " literally turned off " in people who stutter, whereas in normal speakers it is engaged while reading silently or aloud. On the other hand, the area that was stimulated in stutterers was the insula, which is between the Broca's area and Wernicke's area of the left temporal lobe. " [The insula] is a crucial area in controlling your articulatory skills, " says Ingham. By increasing the activity in the auditory association area, it may be possible to turn down this insula overactivity, and that might end the stuttering. Research investigating this possibility started a few weeks ago. The scientists will deliver a brief magnetic charge to the auditory association area of stutterers, which will increase the blood flow to this region. They hope this will also deactivate the insula. It is too early to tell whether this process will work. In the meantime, Rowlett is using his new-found confidence to help others. If he hears a child stuttering, he will approach the parents and encourage them to seek diagnosis and treatment. " I'll go up and say, 'Excuse me, I couldn't help but notice that your son or daughter has something in common with me,' " he says. Jim Rowlett is not running from stuttering anymore. " Talk to you soon! Quote Link to comment Share on other sites More sharing options...
Guest guest Posted August 3, 2001 Report Share Posted August 3, 2001 Our daughter, 7 1/2 years old, has been in speech therapy for severe/profound verbal apraxia since her third birthday. Treatment has consisted of intensive, one-to-one private therapy for 2 to 4 times a week for 4 1/2 years. She currently is classified with mild to moderate verbal apraxia. Also noteworthy is a dual diagnosis of severe disfluency. Her disfluency has fluctuated over the years, but she has had incidents of classic stuttering (her father is stutterer) that were beyond typical apraxic " groping " . She has also struggled with feeding issues around food textures and has dyslexia. We began giving my daughter two ProEFA capsules a day, one in the morning and one in the evening. She weighs 49 pounds and is 49 inches tall. On the seventh day of this regimen, she had an unprecedented burst of fluency. During our family supper, she began telling us stories at a hyper-rapid rate. It was as though she was surprised by the flow of her words and was anxious to tell all that she could, as fast as she was able to do so. I should note that we had out-of-town visitors at the time, and my friend, an early- intervention educational consultant who has observed my daughter closely over the years, was stunned. We all were. This increased fluency has continued for another week, at a steady pace. The initial incident was more intense, but my daughter is now engaging in quicker and more frequent dialogues with siblings and peers. At this point, my daughter shows no markedly-improved articulation. We are impressed by her vocabulary, however, and wonder if she is experiencing less trouble with retrieval. Her receptive language has always been very good. I have been struck several times in the last few days with her creative expressions. For example, she was describing her experience on a rollercoaster. Contextually, she obviously wanted to say she was " anxious. " Instead she said that the ride " haunted " her. It seems she has entered a new relationship with expressive language. Respectfully Submitted, Judy Folkerts Quote Link to comment Share on other sites More sharing options...
Guest guest Posted August 5, 2001 Report Share Posted August 5, 2001 Thank you for sharing your story. It is nice to hear about older children since most of us here have very young ones. I have a 3 year old & fear the worst for his future. He has about 20-30 words but only one at a time. And anyday we loose some. I have had my son on the Pro EFA off & on for just a couple of weeks. Mom to 4 kids can't always remember to give it to him! I am just curious my son uses mostly vowel sounds, when did your daughter begin to add the constanant sounds to the words? We have not gotten to the stuttering stage alot of moms have been talking about, but I worry since my second son stuttered severly as a child. He is now 16, once in a while he will still stutter. To this day I still have trouble understanding him. He talks very quiet & low. I think he does that thinking it will keep him from doing it & if he does no one will realize?? Keep us posted....
