Candida Yeast

According to Henry Butt, M.D. of the University of Melbourne, a person’s general health depends largely on how well his or her body is able to absorb the byproducts of naturally present “gut flora.” Changes to our internal physical environment, especially persistent ones, can cause a variety of gastro-intestinal symptoms, such as diarrhea or abdominal distention. Patients with autism seem to be prone to such GI issues, which may be caused by an overabundance of yeast. According to some schools of thought, elevated yeast levels can cause a variety of autism-like symptoms, including increased sensory defensiveness, inappropriate laughter, and inattention. To date, however, there has been no proof that an elevated yeast level actually causes autism, and the etiology of autism remains unknown.

Ultimately, what Dr. Butt’s research shows is that while we are not yet able to pinpoint the causes of autism, we are reaching a point where we are able to ascertain whether or not secondary treatments, such as diet modification, are able to lessen some of the symptoms associated with autism. By additional outside factors that contribute to autism-like behaviors, we will perhaps be one step closer to finding the ultimate cause of this very prevalent disease.

Recent discoveries in epigenetics could soon make a clinical difference for children with attention-deficit/hyperactivity disorder, autism spectrum disorder, and other conditions, according to an expert.

The implications go beyond targeting treatment for an individual child in your practice based on a specific genetic mutation, Dr. Hakon Hakonarson, director of the center for applied genomics at the Children’s Hospital of Philadelphia, said at a pediatric update sponsored by Miami Children’s Hospital. Recent advances point to gene alterations that modify shared pathways, so the potential for wider application beyond ADHD and ASD — such as unexpected discoveries related to pediatric neuroblastoma — is a real possibility.

Dr. Hakonarson is a member of ICare4Autism’s Advisory Council and will be speaking about the gene networks underlying autism targeted for therapeutic intervention at the upcoming ICare4Autism International Autism Conference being held in Israel.

Hakon Hakonarson, M.D., Ph.D., is an associate professor of Pediatrics at The University of Pennsylvania School of Medicine.  He is a physician-scientist and director of The Children’s Hospital of Philadelphia’s Center for Applied Genomics (CAG), a high-throughput highly automated genotyping facility founded to identify the genetic causes of complex medical disorders in children, such as autism and cancer, with the objective of developing new therapies.

Dr. Hakonarson has an extensive track record in human genetics and has developed an international reputation amongst his peers. He has served previously in several senior posts in the biopharmaceutical industry, including as the director of Inflammatory and Pharmacogenomics Research and the vice president of Clinical Sciences and Development and CSO.

Dr. Hakonarson has also been the principal and co-principal investigator on several NIH-sponsored grants, and he has published numerous high-impact papers on genomic discoveries and their translations in some of the most prestigious scientific medical journals, including Nature, Nature Genetics and The New England Journal of Medicine.

Time Magazine listed Dr. Hakonarson’s autism gene discovery reported in Nature, 2009, among the top 10 medical breakthroughs of that year. With over ten years of experience in pioneering genomics research and genome-wide mapping and association studies, Dr. Hakonarson has intimate knowledge of the complexities of large-scale genomics projects and has put together the necessary infrastructure and workflow processes to unravel these complexities.

The Parent Child Training Program (PCTP) at Action For Autism is a ‘model’ program that addresses the critical need for parent education. How to parent an autistic child is not an intuitive process. True parental involvement is the key to successful autism programming and activities.

PCTP’s training empowers parents to take charge of their children’s health and education. Parental involvement on this level not only helps educate children, but it heals the emotional stresses that parents face. The PCTP training program is a ten-week country wide opportunity.

The coursework covers behavior modification and skills maintenance. Mothers learn tools and tactics for facilitating learning. Most importantly, they gain confidence through community by meeting other parents. This is the goal of ICare4Autism’s conference and our institute at large. By sharing information we strengthen our skills.

Ms. Barua’s organization quotes that they hope for “a society that views the interdependence of people of every ability as valuable and enriching.” AFA seeks to provide equal opportunities for all. Their goals are not only research and expanding autism education in India but also independent life training and skills.

The AFA’s reach goes beyond Los Angeles and India to the Europe. AFA created “Activate Yourself!” to put into action the value of all people. Due to the nature Autism, people with this disorder have difficulties in terms of self-advocating their fundamental rights. Therefore “Activate Yourself” was developed to encourage active participation of young people with ASD; empower them as active citizens, make them aware of their role in creating their own future and promote their equal rights and opportunities. The project is supported by the Youth in Action Programme of the European Union.

This kind of active work is right in line with the International Center for Global Research. We learn as much in the classroom as we do from the scientists in our lab. How to educate our autistic youth comes directly from their communication and achievements.

ICare4Autism Founder and President, Joshua Weinstein with Dr. W. Ted Brown

The Fragile X Syndrome is the most common inherited cause of intellectual disability. Fragile X has a population incidence of approximately 1 in 4,000 affected (full-mutation) males, 1 in 6,000 affected females, 1 in 700 premutation carrier males and 1 in 260 carrier females. This disorder typically causes moderate to severe intellectual deficiency in affected males, and milder deficiency in affected females.  It is associated with autism or PDD-NOS in about 50% of affected males, and most affected individuals evidence some autistic-like behaviors. 

Fragile X syndrome is considered to be the most common known single gene cause of autism. It is estimated that Fragile X accounts for 2-4% of intellectual deficiency overall, and is second to Down syndrome, which is not inherited, as a genetic cause of intellectual deficiency. The fragile X mutation results in the lack of expression of the Fragile X Protein (FMRP), an mRNA finding protein, which results in overexpression of the glutamate (stimulatory) and under-expression of the GABA (inhibitory) pathways in the brain.

Current experimental treatment trails are being carried out in Fragile X and in autism with glutamate receptor blockers and GABA stimulatory drugs.  The underlying defects in neurochemical pathways in both conditions appear to have much in common, involving the ERK, mTOR and PI3K signaling pathways.

Dr. W. Ted Brown will be speaking at the upcoming ICare4Autism International Conference on Autism, in Israel, about the relationship between Fragile X syndrome and autism.

W. Ted Brown, MD, PhD, is the Director of the New York State Institute for Basic Research (IBR) in Developmental Disabilities, Chair of the IBR Department of Human Genetics and Director of the IBR Jervis Clinic.  He is a fellow of the American College of Medical Genetics and Professor at the State University of New York- Downstate Medical Center in Brooklyn.

In 1991, he was appointed the Director of IBR’s Jervis Clinic and in 2005 became IBR’s Director. He is the author of more than 350 publications.  At IBR, he began research focused on the Fragile X syndrome, which was then newly recognized and is now considered to be the most common inherited cause of intellectual deficiency or mental retardation. At IBR, he established a DNA diagnostic and molecular laboratory. He developed a screening and prenatal testing program for Fragile X.

His work on Fragile X has ranged from clinical studies relating to phenotype, to family inheritance studies, to mouse model development, and to basic molecular research. His current research is focused on autism genetics and the Fragile X syndrome.

The daily encounters and friction between the staff of therapists and the families of children with special needs (and sometimes also with the extended family) are often obscured within the obligations of rather complicated professional and mental challenges.

The family of the special needs child – who face a tremendous financial burden on top of the emotional burden they already bear – loses its privacy; they find themselves exposed, against their will, to the team of therapists. Often there are sensitive situations which cannot be hidden, and sometimes the family encounters open or latent criticism. The therapists also find themselves privy to the difficult emotional situation of the family members; crises in the relationships between the child’s parents; and complicated ethical problems: all of which while they are supposed to be providing professional and appropriate treatment for the child with whom they are working.

Inbar Konforti will be speaking about bridging the gap between families and therapists in home-based ABA at the upcoming ICare4Autism International Autism Conference in Israel.

The presentation will cover how parents and family members should be supported and involved in the treatment process, the difficulties experienced by the parents of children with special needs during such complex treatment and the difficulties experienced by the therapists.  She will also discuss how to optimize the effectiveness in applying such a home involvement program.

Inbar Konforti is the founder and Director of the Refael Center (www.merkaz-refael.co.il) – the National Guidance Center to Train Behavioral Therapists ABA; Certified Behavior Analyst BCABA, with 12 years’ experience working with children suffering from autism and delayed development. She is a graduate of the University of Tel Aviv for certification studies in Applied Behavioral Analysis. BA (Honors) in Special Education from Bar Ilan University. Inbar Konforti is a lecturer on ABA at various locations in Israel, instructor of the Home-Based Program, and programs designed to integrate children suffering from autism and delayed development into schools and kindergartens.

Dr. Eli Hatchwell is a member of ICare4Autism’s Advisory Council and will be speaking at ICare4Autism’s International Autism Conference in Jerusalem this August.  He will be speaking about the heritability of autism and will discuss the recently completed project he was involved with which discovered many novel genes in connection with autism.

Dr. Hatchwell’s clinical and technical expertise in investigating human genetic disorders led him to recognize early on that human genetic diversity was grossly underestimated, there was a critical need to comprehensively understand the vast spectrum of normal genetic variation in the population and that rare variants are largely responsible for causing common disease – the underlying principles of the genetic biomarker discovery technology of Population Diagnostics.

He is recognized as a key collaborator in the development of one of the first genome-wide BAC-based comparative genomic hybridization (CGH) microarray platforms and remains at the forefront of cytogenetic and genome analysis through early adoption of leading edge technologies. Dr. Hatchwell collaborates with human genetics researchers worldwide, is a coauthor on numerous peer-reviewed articles, encompassing both clinical genetics and genome technologies, and is senior editor of a book series aimed at educating medical specialists on genetic principles and practices.

Dr. Hatchwell is also a certified Medical Geneticist (UK) with many years of experience in clinical practice. He received his medical degree from the University of Cambridge, his DPhil in Molecular Genetics from the University of Oxford, and was a Wellcome Advanced Clinical Training Fellow. He also holds a degree in Mathematics from the Open University (UK).

His goal is to get together as many genes to formulate tests that are as comprehensive as possible so that autism could be diagnosed medically before clinically. He is also interested in matching genetic causes of autism to potential therapeutic interventions. He believes these complex genetic disorders, will eventually be found to be amalgams of very a variety of very rare disorders.

Dr. Hollander will be speaking at the upcoming ICare4Autism International Autism Conference on the Neuropsychopharmacology of Oxytocin and Inflammation in ASD.  He is also receiving Global Autism Research Award for his breakthrough research in autism treatment at the ICare4Autism Fundraising Gala on Thursday, 7th of June, 2012.

The research, which included 37 high-functioning adults with, mainly diagnosed with Asperger’s syndrome, followed participants for 12 weeks. Taking fluoxetine doubled the chances that a patient would show overall improvement, measured by their clinicians. Half of the participants taking fluoxetine had significant reductions in obsessive-compulsive symptoms, compared with 8% taking placebo.

“Repetitive behavior is a core symptom of the illness,” says lead author Dr. Eric Hollander, medical director of the Autism and Obsessive-Compulsive Spectrum Program at Montefiore Medical Center in New York, explaining that “from a very early age, these children have rituals and routines. For example, they like to line up their toys and they get very bent out of shape if there is any deviation.”

A previous, larger study of a similar medication, citalopram, in children with autism did not find a reduction in repetitive behaviors, but the drug did reduce irritability and was superior to placebo among children who had the highest levels of irritability. Irritability can sometimes lead to repetitive behaviors because people wit autism often engage in these activities to self soothe.

Both fluoxetine and citalopram belong to a class of antidepressants known as selective serotonin reuptake inhibitors, or SSRIs. Prior research on SSRIs in people with autism has also looked at fluvoxamine and found a reduction in repetitive behavior in adults but not children. It is not known if the differences between these studies are due to differences between the medications or other factors.

Obsessive behaviors may also arise in people with autism in response to the stress or discomfort of unpredictable situations. “Many of these individuals have expectations for what’s going to happen, and if there is an unexpected deviation, they experience a lot of discomfort and then they do all these kinds of behaviors,” says Hollander. That’s why people with autism may obsessively avoid locations where they previously experienced discomfort, for example, or they may engage in a repetitive habit like washing, checking, counting, touching or tapping.

When taking fluoxetine, Hollander says, “Patients acknowledge experiencing less discomfort. They’re more able to go outside their comfort zone and to better resist their habits and rituals.” One participant in Hollander’s study was previously too anxious to take the subway or eat in a restaurant, but, when taking fluoxetine, was able to tolerate these unpredictable environments.

Hollander notes that the findings were statistically significant and clinically meaningful. “The clinicians could tell that people were doing better not only in terms of OCD symptoms but overall distress and ability to function.”

It is widely understood that different genes interact with environmental factors to influence autism, but new research finds a common ground as the various genes involved in autism appear to influence special processes in the brain.

Autism is influenced by many different genes, and different genes are involved in different individuals, making it hard to find the common genetic ground between patients.

Now, research conducted at the Hebrew University of Jerusalem has shown that the different genes involved in autism tend to be involved in specific processes in the brain. This can explain similarities in the behavioral symptoms of different people with autism, but also the large spectrum of behaviors observed in different individuals with autism.

The Hebrew University research, conducted by Dr. Sagiv Shifman and his doctoral student Eyal Ben-David of the Department of Genetics at the Alexander Silberman Institute of Life Sciences, has potential implications for early diagnosis as well as for treatment of autism in the future.

Dr. Shifman’s areas of interest are the genetics of schizophrenia and autism and genetics of variation in gene expression.  He will be speaking about this research “Shared neuronal pathways affected by common and rare variants in autism spectrum disorders” at ICare4Autism’s upcoming International Autism Conference in Jerusalem.

The mission of the Hebrew University project was to test the contribution of rare genetic mutations, as well as the genetic variations which are common in the population, and to see whether these different types of genetic risk factors are related. Instead of testing individual genes, the researchers chose to study gene collections, in an attempt to understand general pathways involved in autism.

Based on genetic data from thousands of families with autistic children, the researchers studied the contribution of different groups of genes to autism.

To their surprise, they found – when looking at mutations found in autism as well as thousands of common gene variants that are more frequently seen in individuals with autism – that these mutations and variations are located in specific functional groups.

When looking at families with one individual with autism (sporadic cases), and in families where there is more than one affected individual (multiplex cases), the same variants were seen acting in both cases. These groups of genes are highly active in the first year of life, and are involved in processes of learning, memory, and sensory perception.

The Hebrew University scientists believe that their work could pave the way for large-scale genetic scans in the future that could allow for early diagnosis of autism. Further, the results of their study provide a ray of hope that by concentrating on specific gene groups, it will one day be possible to design drugs which could alleviate symptom

The study, led by Gladstone Investigator Jorge J. Palop, PhD, revealed that low levels of a protein, called Nav1.1, disrupt the electrical activity between brain cells. Such activity is crucial for healthy brain function and memory. Indeed, the researchers found that restoring Nav1.1 levels in mice that were genetically modified to mimic key aspects of Alzheimer’s disease (AD-mice) improved learning and memory functions and increased their lifespan.

“It is estimated that more than 30 million people worldwide suffer from Alzheimer’s disease and that number is expected to rise dramatically in the near future,” said Lennart Mucke, MD, who directs neurological research at Gladstone, an independent and nonprofit biomedical-research organization. “This research improves our understanding of the biological processes that underlie cognitive dysfunction in this disease and could open the door for new therapeutic interventions.”

In the brain, neurons form highly interconnected networks, using chemical and electrical signals to communicate with each other. The researchers investigated whether this communication between neurons is disrupted in AD-mice, and if so, how this may affect the symptoms of Alzheimer’s disease.

“Like a conductor in an orchestra, PV cells regulate brain rhythms by precisely controlling excitatory brain activity,” said Laure Verret, PhD, postdoctoral fellow and lead author. “We found that PV cells in patients with Alzheimer’s and in AD-mice have low levels of the protein Nav1.1 – likely contributing to PV cell dysfunction. As a consequence, AD-mice had abnormal brain rhythms. By restoring Nav1.1 levels, we were able to re-establish normal brain function.”

Indeed, the scientists found that increasing Nav1.1 levels in PV cells improves brain wave activity, learning, memory and survival rates in AD-mice.

“Enhancing Nav1.1 activity, and consequently improving PV cell function, may help in the treatment of Alzheimer’s disease and other neurological disorders associated with gamma-wave alterations and cognitive impairments such as epilepsy, autism and schizophrenia,” said Dr. Palop, who is also an assistant professor of neurology at the University of California, San Francisco, with which Gladstone is affiliated. “These findings may allow us to develop therapies to help patients with these devastating diseases.”

Young brains are capable of forming many new synapses, and are consequently better at learning new things. That is why we acquire vital skills – walking, talking, hearing and seeing – early on in life. The adult brain stabilizes the synapses so that we can use what we have learned in childhood for the rest of our lives. 

Earlier research found that approximately one fifth of the synapses in the brain inhibit rather than excite other nerve-cell activity. Neuroscientists have now shown that many of these inhibitory synapses vanish if the adult brain is forced to learn new skills. They came to this conclusion by labeling inhibitory synapses in mouse brains with fluorescent proteins and then tracking them for several weeks using a specialized microscope. They then closed one of the mice’s eyes temporarily to accustom them to seeing through just one eye. After a few days, the area of the brain that processes information from both eyes began to respond more actively to the open eye. At the same time, many of the inhibitory synapses disappeared and were later replaced by new synapses.

Inhibitory synapses are essential for the way networks function in the brain. “Think of the excitatory synapses as a road network, with traffic being guided from A to B, and the inhibitory synapses as the matrix signs that regulate the traffic,” explains research leader Christiaan Levelt. “The inhibitory synapses ensure an efficient flow of traffic in the brain. If they don’t, the system becomes overloaded, for example as in epilepsy; if they constantly indicate a speed of 20 kilometres an hour, then everything will grind to a halt, for example when an anaesthetic is administered. If you can move the signs to different locations, you can bring about major changes in traffic flows without having to entirely reroute the road network.”

Inhibitory synapses play a immensely influential role on learning in the young brain. People who have neurodevelopmental disorders – including autism – may have trouble forming inhibitory synapses. The discovery that the adult brain is still capable of pruning or forming these synapses offers hope that pharmacological or genetic intervention can be used to manage this process. This could lead to important guideposts for treating autism, but also repairing damaged brain tissue.
