Brain donation project gives scientists priceless help
in search for autism's causes
A gift of
knowledge

During his too-short life, Laura and Daniel Walsh helped their
son, Jason, live with autism.
With the boy's death in May, a month before his 6th birthday, the
Mt. Lebanon couple hopes to help researchers learn more about the
causes and treatment of autism.
The Walshes donated Jason's brain to the Autism Tissue Program in
Princeton, N.J., which makes study samples available to scientists
trying to unravel the mysteries of this neurodevelopmental disorder.
The program is an effort of the Autism Society of America
Foundation, the National Alliance for Autism Research and the
Medical Investigation of Neurodevelopmental Disorders, or M.I.N.D.,
Institute of the University of California at Davis.
Director Jane Pickett talked about the tissue project at the
society's national conference, held earlier this month in
Pittsburgh.
Laura Walsh told the audience about Jason and urged families to
consider participating.
Up until he was 1 1/2, Jason seemed like most kids his age. He
spoke about 10 words, his mother said, including "Dad," "door,"
"down" and "Barney." He hadn't yet mastered "Mom." He made his
family laugh at his antics at the dinner table.
But then everything changed. He rapidly lost words and interest
in interacting.
"He had a clear-cut regression," Walsh said. "It seemed like it
was overnight."
As a youngster, she had told her mother that she wanted to teach
autistic children, and she had written a paper on autism in college.
"It was just a fluke that I ended up having Jason," said Walsh,
an at-home mom. "But I knew what [the problem] was."
She told her pediatrician, who referred Jason to specialists at
Children's Hospital for an assessment. Because the boy was so young,
making the diagnosis wasn't easy. Without one, though, he could not
receive intensive early intervention services.
"I don't care what the diagnosis is, just get him help," Walsh
pleaded.
Diagnosis and therapy
Doctors ruled that Jason had a non-specific pervasive
developmental disorder, which is one of a spectrum of autism
conditions. Soon afterward, he was getting behavioral therapy and
other services at home. Walsh said that his aides predicted that he
would do well because he was coordinated and young enough that he
might regain speech.
"We went on for three-and-a-half years until they finally said it
really wasn't working," Walsh said. "He would learn skills and
forget them like almost overnight."
She also looked into the possibility that Jason had a rare
seizure disorder, for which a Chicago specialist recommended trying
oral steroid therapy. The boy had been taking the pills, which
suppress the immune system, for less than two months when he became
very ill.
Emergency room doctors said it was the flu or croup, and that
he'd be fine. That March night, Walsh tried to ease Jason's
breathing problems by holding his head out of the window and sitting
in a steamy bathroom. By morning, she was so worried that she took
him to his pediatrician more than an hour before his scheduled
appointment, hoping for reassurance. Instead, the boy was rushed
back to Children's and admitted into the intensive care unit.
Jason had developed acute respiratory distress syndrome. For the
next two months, he needed a machine to breathe. Despite numerous
tests and treatments, he didn't improve.
"After a while, it was like we were torturing him," Walsh said.
"An autistic child doesn't want to be poked and prodded. The last
thing Jason wanted to do was be with a bunch of strangers."
Hearing that he was unlikely to recover, the family stopped
taking extraordinary measures to keep him alive. Walsh had wanted to
donate her son's organs for transplantation, but other medical
issues prevented that. And then another thought popped into her
head.
"What can we do for autism?" she wondered. "I had worked so hard
to help my son and I know there's a million parents out there doing
the same thing."
A doctor searched the Web site of the
National Alliance for
Autism Research and learned about the tissue program. When Jason
died on May 9, the Walshes donated his brain.
Mortality patterns
It was families like the Walshes that got the tissue program
going, Pickett said.
Autism is estimated to affect up to 1.5 million Americans, and is
four times more common in boys than girls. When the tissue program
began in 1998, no one thought that mortality rates were any
different among autistic children than in the general population.
"The idea was it would be a fairly passive program," said
Pickett, who thought it would be years before much information could
be collected and analyzed.
A couple of years after the program began, three autistic
children younger than 10 died during the same summer, catching her
attention. The cause of death couldn't be determined in some cases.
About half of the 57 brains the project has banked so far came from
people younger than 16.
In addition, Pickett's 15-year study of 13,000 autistic children
in California revealed that there were more deaths than expected
among 5- to 10-year-olds, particularly girls. "We don't know what
that means, either," she said.
Drowning is probably the most common cause, Pickett added.
Children with autism are often fascinated by water.
"The thing I've heard from parents is that their child is a
little Houdini who gets out and around and through every latch and
lock and into areas that are dangerous," Pickett said. Medication
problems and seizure disorders are other possibilities, and the
project's scientific advisory board include experts in those areas.
Dr. Nancy Minshew, director of the Center for Autism Research at
the University of Pittsburgh School of Medicine, recently joined the
board. Her center soon will provide links to the tissue project on
its Web site and make more information available.
"Being able to look directly at the brain is one of the most
precious scientific tools that we have," she said. Families need to
know that brain donation is an opportunity to make "a golden gift to
autism," as she put it.
The Walshes believe that without brain tissue to study,
scientists might not figure out autism's causes. Without causes, how
can they figure out treatments?
"I believe giving Jason's brain will put us one step closer to
solving the mystery," Laura Walsh said.
"I believe Jason was sent here for a reason. Perhaps this program
was one of the reasons."
