What Are the Symptoms of Autism Spectrum Disorder?
Signs of Autism in Adults
While signs of autism spectrum disorder (ASD) often appear during early childhood, some individuals may not receive a diagnosis until adulthood. In adults, signs can include difficulties with social interactions, such as understanding nonverbal cues or maintaining conversations. They may also have restricted and repetitive interests or behaviors and may struggle with adapting to changes in routine or environment.
Main Autism Symptoms: Communication and Behavioral Patterns
ASD is primarily characterized by differences in communication and behavioral patterns. In communication, this may involve delays in speech development, challenges in using and understanding language, and difficulties in holding two-way conversations. Behaviorally, individuals with ASD may display repetitive actions, have specific routines or rituals, and exhibit strong interests in specific topics.
What’s Your Level of Support?
The level of support required by individuals with ASD can vary greatly. Some may live independently and only need occasional assistance, while others might require more substantial, daily support. It is also important to recognize that the term 'high functioning' is not preferred by many individuals and advocates, as it can be misleading about the challenges faced daily.
How is Autism Spectrum Disorder Diagnosed?
ASD diagnosis involves a multifaceted evaluation process, including developmental history and behavior assessments. Diagnoses are made based on criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which considers both communication skills and behavioral patterns.
Language Matters
The language used to discuss ASD is significant. Person-first language (e.g., 'person with autism') and identity-first language (e.g., 'autistic person') are both used, and preferences can vary among individuals with ASD. It is always best to ask or follow the person's lead on which terminology they prefer to be used.
Communication Patterns
Communication patterns in individuals with ASD can include atypical speech rhythm, limited use of gestures for communication, or a preference for solitary or parallel play in children. Some may also develop strong language skills but still struggle with the subtleties of conversation, such as humor or sarcasm.
Behavioral Patterns
Common behavioral patterns seen in ASD are repetitive movements, such as rocking or hand-flapping, an intense focus on specific interests, and insistence on sameness and routines. Sensory sensitivities to sounds, lights, touch, and tastes are also frequent.
Outdated Diagnoses
Previously, separate diagnoses such as Asperger's syndrome, pervasive developmental disorder-not otherwise specified (PDD-NOS), and autistic disorder were used. These are now all encompassed under the ASD umbrella in the DSM-5 to better reflect the condition's spectrum nature.
