Inside this issue:
Hello everyone,
WAADF has had a very busy and productive year in 2006. Our second AGM in September saw some changes in the Board. Kate Smith and Wendy Mar-shall resigned. Kate has moved over to the Justice Department and Wendy Marshall has re-cently had a new baby boy (Drew). The Board would like to thank them both for their outstanding commitment and hard work for WAADF. We also welcome Helen Bolton and Sandra Gray who have joined the Board as Co-Secretaries – their personal organization and efficiency has enabled a seam-less transition. Ongoing Board members include Ritu Camp-bell, Suzanne Midford, Robyn Weinstein, John Wray, Jane Lesslie, Alana Maley-Berg, Jane Klinken and Sabrina De Beer. Sabrina has also taken over as Editor of WAADF’s quarterly newsletter and is doing an out-standing job – all items of inter-est are happily accepted so please send them to Sabrina who will keep them for inclu-sion in upcoming editions.
WAADF also had the opportu-nity this year to make its pres-ence known on the interna-tional stage. I had the honour of presenting WAADF at the 2nd Autism Congress in South Af-rica. Our presentation (attached to the December Forum minutes) was well at-tended and several delegates were interested in purchasing WAADF’s publications. A par-ticularly interesting outcome has been the follow-up contact
received from the Northern Ireland Diagnostic Special Inter-est Group. In addition to them purchasing several copies of our booklets, we are currently discussing ways in which our groups can form a collaborative and ongoing relationship with the potential to mutually ex-pand and strengthen our think-ing and practices in a variety of areas. In a similar vein, Glenys Dixon was discussing WAADF with fellow delegates at the autism research conference in Canada earlier this year. There is a lot of interest in what we are doing here in WA, in fact Glenys ended up giving her copy of the Assessors’ manual to a member of the Centre for Diseases Control in the US. It will be interesting to see where all of this leads….we’ll keep you posted!
The WAADF Board is working towards developing and ex-panding the group as a whole and its members services in particular. One part of this has been the ongoing refinement and expansion of the website – under the talented guidance of Alana Maley-Berg. We are cur-rently working on developing a Members Only part of the web-site as well as reviewing and refining the general access por-tions ~ please drop by and check it out when you have a chance. All feedback is appreci-ated!
Ritu Campbell has done an excellent job this year of put-ting together a wide range of speakers, including case discus-sions as well as topics of inter-
est. If any members have a case they would like to present or other suggestions for speakers or topics please contact Ritu directly.
Suzanne Midford has continued to manage the job of WAADF Treasurer, including dealing with the ATO and the inevita-ble paperwork that incurs! We have just completed a review of our membership and realise that not all past financial mem-bers have renewed their mem-bership. There will be a flyer going out soon to all non-financial members reminding them of the renewal date and the benefits of membership. If you receive one of these flyers please take a moment and con-sider supporting WAADF so that it can continue to grow as an effective voice for autism in the community as well as a practical support to practitio-ners.
We hope that you enjoy this edition of the newsletter ~ please feel free to provide sug-gestions and feedback so that it can continue to develop to meet your needs.
On behalf of the WAADF Board I want to wish you all a happy and safe holiday season, and fun and relaxation with friends and families over this summer period. We look for-ward to seeing everyone in 2007.
Regards,
Sarah MacDermott

It is really important that the child's dis-ability not become the entire focus. The child should live in your house rather than you living in their house. Otherwise the family is defined by the dis-ability and the child, the marriage and the other children all suf-fer. The child has spe-cial challenges and he is also a member of the family.

We’re always on the look-out for volunteers to share diagnostic case studies with members at the WAADF meetings. In the past we have
had wonderful presentations from our members on topics such as elec-tive mutism, visual impairment, Down Syndrome and semantic-
pragmatic disorder. These presentations not only make our meetings more interesting, but add to the professional development of our diag-nostic community. If you have a case to present, don’t be shy! We’d
love to hear from you. Please contact the WAADF agenda coordinator, Ritu Campbell on [email protected]. Cheers!
Inside the Autistic Mind Excerpt from an Article in TIME Magazine Sunday May 7, 2006
Call for Case Presentations
THE AUTISTIC BRAIN
Whether the cause is maternal antibodies, heavy metals or some-thing else, there is no question that the brains of young children with autism have unusual features. To begin with, they tend to be too big. In studies based on magnetic resonance imaging (MRI) and basic tape-measure readings, neuroscientist Eric Courchesne at Children's Hospital of San Diego showed that while children with autism are born with ordinary-size brains, they experience a rapid expansion by age 2--particularly in the frontal lobes. By age 4, says Courchesne, autistic children tend to have brains the size of a normal 13-year-old. This aberrant growth is even more pro-nounced in girls, he says, although for reasons that remain myste-rious, only 1 out of 5 children with autism is female. More recent studies by Amaral and others have found that the amygdala, an area associated with social behavior, is also oversize, a finding Amaral believes is related to the high levels of anxiety seen in as many as 80% of people with autism.
Harvard pediatric neurologist Dr. Martha Herbert reported last year that the excess white matter in autistic brains has a specific distribution: local areas tend to be overconnected, while links between more distant regions of the brain are weak. The brain's right and left hemispheres are also poorly connected. It's as if there are too many competing local services but no long distance.
This observation jibes neatly with imaging studies that look at live brain activity in autistic people. Studies using functional MRI show a lack of coordination among brain regions, says Marcel Just, di-rector of Carnegie Mellon's Center for Cognitive Brain Imaging in Pittsburgh, Pa. Just has scanned dozens of 15- to 35-year-old autistic people with IQs in the normal range, giving them thinking tasks as he monitors their brain activity. "One thing you see," says
Just, "is that [activity in] different areas is not going up and down at the same time. There's a lack of synchronization, sort of like a difference between a jam session and a string quartet. In autism, each area does its own thing."
What remains unclear is whether the interconnectivity problem is the result of autism or its cause. Perhaps all that excess wiring is like the extra blood vessels around the heart of a person who has suffered a heart attack--the body's attempt to route around a problem. Or perhaps the abnormal growth of the brain has to do with the immune system; researchers at Johns Hopkins have found signs that autistic brains have chronic inflammation. "It's impossible to tell the chicken from the egg at this point," Just says.Autistic people have been shown to use their brains in un-usual ways: they memorize alphabet characters in a part of the brain that ordinarily processes shapes. They tend to use the visual centers in the back of the brain for tasks usually handled by the prefrontal cortex. They often look at the mouth instead of the eyes of someone who is speaking. Their focus, says psychologist Ami Klin of Yale's Child Study Center, is "not on the social alle-giances--for example, the longing gaze of a mother--but physical allegiances--a mouth that moves."
Do these differences reflect fundamental pathology, or are they downstream effects of some more basic problem? No one knows. But the fact that early intervention brings better results for children with ASD could be a clue that some of the odd brain anatomy and activity are secondary--and perhaps even prevent-able. Studies that look at whether early therapy might help nor-malize the brain are beginning at York University in Toronto, but results are probably years away.
A wealth of new brain research--and poignant testimony from people who have autism--is lifting the veil on this mysterious condition By CLAUDIA WALLIS
" ... If we could eliminate the genes for things like autism, I think it would be disastrous. The healthiest state for a gene pool is maximum diversity of things that might be good."

WA REGISTER FOR AUTISM SPECTRUM
DISORDERS
Background
Autism spectrum disorders include all autism-related conditions described medically as Perva-sive Developmental Disorders. These are: Au-tism, Asperger syndrome, Childhood Disintegra-tive Disorder, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS). Although Rett syndrome is also categorised as a Pervasive Developmental Disorder, people diagnosed with Rett syndrome are not included on this register.
Autism spectrum disorders are characterised clinically by significant impairment in three areas of development: a) poor social interaction; b) deficits in communication; and c) restricted range of interests. Symptoms may be apparent before 30 months of age, but diagnosis is tenta-tive before this time. Many children have difficul-ties integrating into society (e.g. in school, social gatherings and sporting activities), and each require varying degrees of supervision and sup-port in daily living.
Current understanding of the aetiology and intervention strategies for autism spectrum disorders is limited. The WA Autism Register serves as a primary resource to researchers, clinicians and service providers to assist with our knowledge of these complex disorders. Western Australia (WA) has a variety of com-prehensive state databases and its geographic isolation and centrally distributed population makes it an ideal location to manage a register. The WA Autism Register is prospective, collect-ing information on all people diagnosed in WA since January 1999.
Purpose and aims
The Register collects information that is useful in describing the pattern of autism diagnoses in WA, including;
• The number and ages of people diagnosed
• The severity of disability
• Shared biological, psychiatric and developmen-tal features
• Group changes over time
The Register has several applications;
• Research
S Epidemiology
S Biology and psychology
S Longitudinal studies
• Planning for services
S Health
S Education
S Disability
Types of information collected
The Register collects simple demographic and diagnostic information such as;
• Date of birth, gender, primary language at home
• Diagnostic criteria used
• Diagnostic methods
• IQ (verbal and non-verbal) and/or develop-mental abilities
• Other cognitive assessments
• Comorbidity (the presence of other condi-tions)
• Language assessments
• Adaptive behaviour
The Advisory Committee
The Register is governed by an Advisory Com-mittee. It currently comprises of one parent representative; two psychologists, one psychia-trist, and one speech pathologist in private prac-tice; and representatives from the two major diagnostic centres (Disability Services Commis-sion and the State Child Development Centre). Each member was nominated by the institution they represent. The Advisory Committee meets on a regular basis. Issues that are discussed at meetings include the running and methodology of the Register, ethical issues, political concerns, diagnostic issues, and diagnostic training oppor-tunities.
Confidentiality
The Register is bound by a confidentiality proto-col (see Appendix). Information is stored on a non-networked computer that is kept in a locked room on secure premises at the Tele-thon Institute for Child Health Research, and is password protected. Requests for simple data are made to the Registrar, and the Advisory Committee considers requests for more com-plex data.
Ethical approval to collect data for the Register was received from the University of Western Australia, Princess Margaret Hospital, Disability Services Commission, State Child Development Centre, and the Royal Australian and New Zea-land College of Psychiatrists.
Notifications to the Register
A data collection form for each newly diagnosed case is completed by a clinician at the time of diagnosis and sent to the Register. The clinician fills in the diagnostic and demographic details that are available to them. For the confidential information (name, date of birth, postcode) to
be included with the entry, consent must be obtained from the parents or persons them-selves. The confidential information helps to eliminate double entries of notifications to the Register, to recognise changes in diagnoses within the same person over time, and to assist with the manual checking of numbers received at the Register with numbers diagnosed at each centre. At the end of each year, the major diag-nosing centres review their records for any cases that have been missed.
Register documents
The Register has several formal documents – a data collection form, consent form, information sheet, and a research interest form. It also has documentation of the terms of reference and confidentiality guidelines.
Changes in documents over time
Several of the documents have been modified since the Register began data collection. Minor changes to the information sheet and consent form and several changes to the data collection form have been made. All changes were ap-proved by the relevant ethics committees.
Requests for information
Since its inception, the Register has received a large number of requests from local, interstate and international sources for data, information, and research participants. Requests have been made from government departments, autism service providers, researchers, students, and the media.
Funding
Initial funding for the Register was received from two sources; the Disability Services Commis-sion, and the Australian Rotary Health Research Fund. Since 2002, funds have been received from both the WA Department of Education and the WA Department of Health to maintain its activi-ties. The financial support of these Departments is greatly appreciated.

An Asperger Dictionary of Everyday Expressions 2nd edition
BIC: CGD JC VFPD
Praise for the first edi-
tion:
'This is a truly inspira-tional book and teach-ing tool and a very successful dictionary for all. It should be on the bookshelves of every inclusive class-room, house and of-fice.'
– Good Autism Prac-
tice
'A useful addition to the reference library of par-ents and professionals working with children and adults with Autistic Spectrum Disorders.'
– The National Association for Gifted Children
'...illustrates just how complex the English lan-guage is... A brilliant idea if you're not sure what an expression means or which one to use.'
This revised and expanded edition adds over 300 new expressions that help unlock the meaning of everyday expressions.
Both informative and entertaining, the book ad-dresses an important aspect of social communi-cation for people with Asperger Syndrome, who use direct, precise language and 'take things literally'. This dictionary aims to dispel any con-fusion that arises from the misinterpretation of language. It provides explanations of over 5000 idiomatic expressions and a useful guide to their politeness level. Each expression is accompa-nied by a clear explanation of its meaning and when and how it might be used. The expres-sions are taken from British and American Eng-lish, with some Australian expressions included as well.
Although the book is primarily intended for peo-ple with Asperger Syndrome, it will be useful for anyone who has problems understanding idio-matic and colloquial English. An essential re-source and an informative read; this dictionary will assist in a wide range of situations.
Asperger Syndrome A Different Mind
Narrated by Simon Baron-Cohen, this DVD presents viewers with the opportunity to both see and hear about the nature of Asperger Syn-drome from children and adults themselves who have AS, as well as from their fam-ily members and school teach-ers.
With video footage from a range of contexts, including leisure time at home, lessons and playtime at school and individual accounts of experi-ences of AS, it provides imme-
diate insight into the lives of six individuals, from Joe, aged 5, to twins Peter and Matthew, 22. Asperger Syndrome: A Different Mind introduces the viewer to the special interests, speech and language charac-teristics, social interaction dif-ficulties and cognitive chal-lenges of people with AS. It also highlights the positive developments that have taken place in recent years, within schools particularly, towards a better understanding of, and more effective provision for, children with AS. This is an excellent introduc-tion to Asperger Syndrome for parents, teachers and other professionals.

Let’s Talk About… Research!
The following excerpt of an article
came from the Autism Speaks website.
The website has a UK and Canada
focus ,but contains some interesting
resources and is worth having a
browse! www..AutismSpeaks.org
In a multi-center study of 222 families in the United States,
scientists have found a strong
genetic link to autism on chromo-
some 7. The study, in which five
large universities participated, was
part of the National Institutes of
Health Collaborative Programs of
Excellence in Autism, or CPEA.
The results were published in the
August, 2006 issue of Molecular
Psychiatry.
Autism, a neurodevelopmental
disorder in which a child exhibits
impaired development in social
interaction and language, and
repetitive, or a restricted range of,
activities, affects up to l.5 million
Americans, and is the nation's
fastest growing development dis-
ability.
Statistics show that most children
develop symptoms of autism in
their first year, but about 25 per-
cent seem to develop normally,
then show regression in the sec-
ond and third years of life. Previ-
ous studies indicate that there is a
genetic role in autism: if one
identical twin has autism, the
other is 69 percent -95 percent
more likely to have the disorder
also. Fraternal twins are only 0
percent -24 percent more likely to
share the disorder, similar to non-
twin siblings at 2.8 percent-7
percent more likely.
Specific Genetic Link to Autism
The search for a genetic link to
autism has been elusive. Accord-
ing to the researchers of the cur-
rent study, the extent of genetic
variation in autism is unknown,
and if extensive, could make it
very difficult to detect specific
locations in the genome. But they
suggest that the differences in
results across previous linkage
studies may also reflect the wide
variety of study designs and the
inconsistency of diagnostic criteria
used.
In this study, the researchers used
the strictest diagnosis of autism in
affected individuals. In previous
linkage studies, autism has been
associated with various regions of
chromosomes and, more recently,
with relatively rare single gene
disorders, such as fragile X syn-
drome, the most commonly inher-
ited form of mental impairment
according to the Fragile X Re-
search Foundation.
Among the regions that have been
identified in various studies are 1p
(“p” signifying the long arm of the
chromosome), 2 q (the “q” signify-
ing the short arm of the chromo-
some), 7q, 17q, and 19q, with the
2q, 7q and 17q regions giving the
strongest signals.
Link to Chromosome 7q
To identify regions of the genome
containing autism genes, the
researchers performed a genome-
wide linkage scan using the geno-
types (the genetic make-ups) of the
individuals in the participating
222 families. The strongest link to
autism was observed on chromo-
some 7q, overlapping positive
results of analyses from the Inter-
national Molecular Genetic Study
of Autism Consortium, and other
previous studies.
The research team attempted to
duplicate gender-related links
found on chromosomes 4, 7 and
17 in previous studies. They
found the strongest signal from
the primary genome scan of both
male and female families was seen
at a localized point on chromo-
some 7, with a stronger result
from the male only families com-
pared to female only families. The
strongest male only signal was on
chromosome 11 and for the fe-
male only group on chromosome
4, the latter comparable to find-
ings from the Autism Genetic
Resource Exchange consortium.
The team observed no signal for
either sex on chromosome 17.
The researchers also sought to
replicate previous studies related
to regression, where linkage sig-
nals had been observed on chro-
mosomes 7 and 21. The families
were analyzed in two groups,
those with at least one affected
individual with regression versus
families with no cases of regres-
sion. The researchers observed
modest linkage signals for the
regression-positive group on chro-
mosomes 10 and 14, and more
significant peaks in the regression-
negative group on chromosomes 3
and 4. Using language acquisition
data as a quantitative trait in their
linkage analysis, the researchers
observed a chromosome 9 signal
among the regression-positive
group.
Discussion and Caveats
Because of the high male -to-
female ratio of autism (three-to-
four males to every female with
the disorder), the researchers
suggest that the observed differ-
ences in gender linkages present
the possibility that there may be
male- and female-specific genes, or
more likely, that the ability of
some susceptibility genes to effect
male versus female subjects is
significantly different.
When only regression-negative
families were considered, evidence
for genetic linkage on both chro-
mosomes 4 and 3 increased mark-
edly, suggesting differences in the
genetics underlying regression
versus the genetics of early devel-
oping autism in non-regression
subjects.
In comparing their study results to
other studies, the researchers
believe they “provided strong
support for a chromosome 7 au-
tism locus and lesser but still
compelling support for loci on
chromosomes 3, 4 and 11.” They
were unable, however, to repro-
duce significant signals reported
by others previously. They believe
this may be explained by the fact
that not all studies have the large
sample sizes needed and the possi-
bility that some of the smaller
signals, including those reported
in the current study, may have
been false-positive results.
The variation in findings may be
due to differences across studies
in the definition of traits and in
the gathering of family history.
The research team tried to mini-
mize the variations by using a
rigorous diagnostic protocol and
the strictest criteria for autism.
But some signals were more sig-
nificant for the broad diagnosis
than for the strict diagnosis of
autism. Thus, the researchers
believe that the strict criteria used
may actually have reduced the
evidence in favor of genetic link-
age by eliminating some families
or individuals that would have
added to the evidence for linkage.
The researchers called for larger
sample sizes for linkage identifica-
tion and replication to establish
their significance in the field, but
not at the expense of increasing
the heterogeneity, or variation of
characteristics, among the study
groups. They believe it may be
useful to identify subgroups of
phenotypes, the observable sets of
traits or characteristics of people
as determined by genes and the
environments in which they devel-
oped.
Analysis of autism endopheno-
types, which are characteristics
unseen by the unaided eye that
are normally associated with a
condition but are not direct symp-
toms of the disorder, may permit
mapping of genetic locations that
contribute to the specific domains
of autism (social interaction, lan-
guage, restricted range of activi-
ties) that would be difficult to
genetically map using only diagno-
sis as the trait.
Finally, additional tools may be
needed and designed specifically
for quantitative traits related to
autism in both affected and nor-
mal individuals so that phenotypic
information from all family mem-
bers can be used to increase the
power to detect linkage.
