What is Autism?

Autism, also known as Autism Spectrum Disorder (ASD), encompasses a wide spectrum of conditions marked by difficulties in social interaction, repetitive behaviours, as well as speech and nonverbal communication challenges. The Centers for Disease Control reports that in the United States, México and Canadá, approximately 1 in 36 children and 1 in 45 adults are affected by autism.

Autism manifests in diverse ways, recognizing that it presents a unique combination of strengths and challenges for each individual. While some individuals with autism may have verbal communication abilities, others might be nonverbal or have minimal verbal communication, utilizing alternative methods for interaction. The intellectual abilities among those with autism also vary widely, with some experiencing intellectual disabilities and others not. The degree of daily support needed can range significantly, from substantial assistance to complete independence.

Diagnosis of autism typically occurs around the age of 5 in the U.S., with early signs detectable by ages 2 to 3. The DSM-5-TR outlines three levels of autism, categorizing the condition based on the needed support level.

Additionally, individuals with autism may encounter other health issues that impact their quality of life, including ADHD, anxiety, depression, gastrointestinal disorders, seizures, and sleep disturbances.

Autism does not discriminate by gender, age, race, or ethnicity, although studies indicate that males are diagnosed four times more frequently than females. It's acknowledged that autism may present differently between genders, with girls often displaying less obvious symptoms, leading to potential underdiagnosis or misdiagnosis. Adults, too, may face challenges in receiving a diagnosis, as many learn to mask their symptoms.

Autism is a lifelong journey with evolving needs and strengths. Support and accommodations vary as individuals progress through different life stages. Early interventions and therapeutic approaches are crucial in enhancing abilities and life outcomes for those on the spectrum.

We believe that understanding and support for autism can unlock incredible potential and enrich lives, opening up a world of possibilities for everyone involved.

Our Mission

Autism Spectrum Disorder screening 

Autism Spectrum Disorder (ASD) cannot be diagnosed through medical tests such as blood work. Instead, it requires the expertise of medical professionals who review the individual's developmental history and behavior, conduct interviews and observations with them and their families, and employ specialized screening and diagnostic instruments.

Diagnoses of autism are exclusively made by qualified healthcare practitioners, yet various screening tools exist to signal potential symptoms of autism to parents, caregivers, and individuals themselves. Early detection is crucial as it can significantly enhance the accessibility of necessary services and support, potentially improving the life quality and outcomes for those with autism.

A range of screening tools exists to assist in identifying potential ASD in both children and adults. While this list is not comprehensive, and more tools are available, it's important to understand that a positive screening does not equate to a formal diagnosis. Instead, any positive indication from these tools should prompt a detailed evaluation by a healthcare professional.


What causes autism?

Autism Spectrum Disorder (ASD) emerges from a complex interplay of genetic and environmental factors, rather than a singular cause. This multifactorial origin contributes to the diversity in autism presentations and its spectrum nature. It's crucial to understand that risk factors do not equate to direct causation. For instance, genetic variations linked to autism might also be present in individuals without the condition, and not all individuals exposed to certain environmental risk factors will develop ASD.

The path to autism involves key developmental stages of the brain. Risk genes for autism often regulate the activity of other genes or affect neuronal communication and brain region interactions. Ongoing research aims to untangle these biological mechanisms to foster better interventions that enhance the lives of those with autism.

Concerning vaccines, extensive scientific studies have conclusively shown no causal relationship between vaccines and autism. Vaccinations are essential in preventing serious diseases and do not contribute to the development of ASD.

Genetics play a significant role in autism, with studies indicating that 60 to 90% of autism risk factors are hereditary. Autism often runs in families, indicating a genetic predisposition that can be triggered by various environmental factors.

Genetic testing for ASD can uncover specific genetic variations associated with autism, providing insights into individual conditions and guiding tailored intervention strategies.

Environmental factors also influence autism risk, including advanced parental age, prenatal exposure to pollutants, maternal health conditions, prematurity, and birth complications. These factors do not cause autism independently but may contribute to its development in the context of genetic predispositions.

Understanding the causes and influences on autism spectrum disorder is vital for early identification, intervention, and support, improving the quality of life for those on the spectrum and their families.
