I am an 18-year-old student who has stuttered for as long

Ravi from India
I am a 30-year-old male with a stuttering
problem since childhood. Recently my 3-year-old daughter also has
started stuttering. I need help.
Marc from California
I’m a 43-year-old white male and a recently
divorced single parent of three boys. My ex-wife left me and one of the
reasons was that she wanted to be with someone fluent and she “tolerated”
me for 17 years. Now I’m alone (my biggest fear) and am having a hard
time in the dating field.
Meredith from South Carolina
I am getting married next year and I want to
say my vows without stuttering. I have trouble saying my fiancé’s
name when I am talking about him but not when I am talking with him.
Greg from New York
I am 47 years old, married with three sons, and
work as a computer operations manager. I have stuttered most of my life
and had come to terms with it. A bad work experience a few years ago put
my fluency into a nosedive.
Katrina from Colorado
Every generation of my mother’s side of the
family has a lot of members who stutter. Now five out of seven of my
mother’s grandchildren stutter, including my 4-year-old daughter. What
can I do to help my child with this speech deficiency so she won’t go
through as much pain and suffering as I have?
Gary from New Jersey
I’m a 47-year-old M.D. who stutters. I’m
available to discuss with anyone who stutters the fact that it is
possible to stutter and still have a highly successful professional,
educational and personal life if you learn to accept that you stutter
and then ignore it after you learn whatever techniques help you minimize
Alicia from South Africa
I’m 18 years old and I’ve had a stammer
since birth. The severity of it seems to go in cycles. Some-times it’s
not very often and sometimes it’s all the time. I hate it with a
passion! It is a major embarrassment and I wish it would go away.
Thomas from Texas
I’m 17 and I’ve stuttered since I was 8. I
am currently in high school, and I would like to talk with anyone who
can relate and tell me more about stuttering. I have been to many
therapists and nothing seems to work. It only gets worse. Is there
anything I can do to control it?
Kimberly from Wisconsin
I’m a business writer and editor who stutters
severely. Language is both my greatest joy and my most loathed and

intermittent years of fluency, but now I seem to be “locked”

I am a 21-year-old married male who has

its kind anywhere. Funded by a three-year, $921,000 grant from the

and 10 non-stuttering women. A similar study has already been conducted
on 20 male participants.

the study, participants are placed in the positron emission tomography
system (PET) where radiation traces the parts of the brain being used.
PET images show brain activity, such as speech, while it is occurring.
The Inghams will be able to map where brain activity occurs during normal
and stuttered speech and then compare
the maps for differences.
the stuttering study with men was conducted at RIC, experts strongly
believed there was a difference
in the brains of stutterers and non-stutterers, Dr. Roger Ingham said.
when the brain maps of the two groups at rest (when they were not
speaking) were compared, there was no difference in their brain
activity. This suggests that the neural malfunctioning
behind stuttering is found only during speech. In earlier studies the
research team found
activity in the premotor, motor and auditory
association regions of the cortex. The current study is looking at
speech activity in these areas.

and then while they are not stuttering, which is during chorus reading,”
Dr. Roger Ingham said. “During stuttered speech, we found that the
pre-motor area of the brain was activated, but the auditory association
area was deactivated. But during chorus reading, these two areas of the
brain came toward more normal activation.”

designed to minimize or eliminate stuttering,” said Dr. Roger Ingham.
“We can look at behavioral and other procedures, including possible
TMS (transcranial magnetic brain stimulation) treatment and drug

study on TMS and stuttering is being conducted through a grant from the
Charles A. Dana Foundation. Dr. Fox said the study is focusing on the
brain’s response to TMS, in which a magnetic field is used to
stimulate a part of the brain. (For example, by stimulating a specific
portion of the brain, the TMS can make a person’s thumb move because
it activates the part of the brain that controls such movement.)
“In stutterers, we’re trying to down-regulate an abnormal area. In earlier
studies, we’ve identified a number of areas that are overactive in
stuttering and a smaller number that are underactive. In this study, we
will direct TMS therapy at a motor planning center near the top of the

this trial of TMS in stuttering. Other sites are conducting studies on
the effects of treatments using prolonged speech [a strategy that
teaches stutterers to prolong syllables slightly to control their
stuttering], but none is investigating the physiology of treatment with
TMS,” Dr. Fox said.

playing key roles in the future treatment of stuttering.
