What Are the 3 Main Symptoms of Autism?

Autism Spectrum Disorder (ASD) is a developmental condition that affects how a person perceives and interacts with the world around them. It is characterized by a range of symptoms and severity levels, making each individual with autism unique. Autism is typically diagnosed in early childhood, but it can also be identified later in life. Although symptoms vary widely, there are three main symptoms that are commonly observed in individuals with autism: social communication challenges, repetitive behaviors, and sensory sensitivities. In this blog, we’ll explore these core symptoms, providing a deeper understanding of each one and how they impact the lives of those with autism.

Symptoms of Autism

1. Social Communication Challenges 

What Are Social Communication Challenges? One of the hallmark features of autism is difficulty in social communication. Individuals with autism may struggle with verbal and nonverbal communication skills, making it challenging for them to connect with others in traditional ways. These challenges can manifest in several ways:

  • Difficulty in Understanding Social Cues: People with autism may find it hard to understand facial expressions, body language, and tone of voice. For example, they might not recognize when someone is joking, frustrated, or expressing sympathy, which can make social interactions confusing.
  • Challenges with Eye Contact: Many individuals with autism avoid eye contact, which is often perceived as a lack of interest or disengagement. However, this behavior usually stems from discomfort rather than disinterest.
  • Delayed or Atypical Speech Development: Some children with autism may experience delays in developing speech or use language in unique ways. For instance, they might repeat phrases (echolalia) or use advanced vocabulary in rigid, formal patterns. Some may also be nonverbal and use alternative communication methods like picture exchange systems or speech-generating devices.

Impact on Daily Life These communication challenges can make it difficult for individuals with autism to form relationships, navigate social settings, or advocate for themselves. It’s essential for caregivers and peers to understand these difficulties and use patience and tailored communication techniques, like using simple language or visual aids, to help bridge the gap.

2. Repetitive Behaviors

What Are Repetitive Behaviors? Repetitive behaviors, also known as "stimming" (self-stimulatory behavior), are another common symptom of autism. These behaviors can include repetitive movements, sounds, or activities, such as:

  • Hand-Flapping or Rocking: Many people with autism engage in physical behaviors like hand-flapping, rocking back and forth, or spinning. These actions can be a way to self-soothe or cope with sensory overload or stress.
  • Strict Routines: Individuals with autism often prefer routines and may become upset if their daily schedule is disrupted. For example, they might want to follow the same route to school or insist on eating meals in a particular order.
  • Focused Interests: Some people with autism develop intense, focused interests in specific topics or objects. For example, they might have a deep knowledge of trains, space, or a particular type of animal, and they may spend hours learning about these interests.

Impact on Daily Life Repetitive behaviors can serve as a way for individuals with autism to regulate their emotions and make sense of their environment. However, when these behaviors become disruptive or interfere with daily activities, it may be necessary to seek support from therapists who specialize in Applied Behavior Analysis (ABA) or other evidence-based interventions to help manage these behaviors constructively.

3. Sensory Sensitivities

What Are Sensory Sensitivities? People with autism often experience heightened or diminished sensitivity to sensory stimuli. This means that their senses—like sight, sound, touch, taste, and smell—can be either more intense or less responsive than those of others. Common sensory sensitivities include:

  • Overreactivity: Some individuals may be hypersensitive to sensory input. For example, they might find certain lights too bright, sounds too loud, or certain textures of clothing extremely uncomfortable. A busy, noisy environment like a shopping mall can become overwhelming, leading to distress or meltdowns.
  • Underreactivity: Others may have hyposensitivity, meaning they might not respond to certain sensory inputs. For instance, they might not notice pain or temperature changes as quickly as others, or they might seek out certain sensory experiences, such as touching objects with interesting textures or enjoying deep pressure.
  • Sensory Overload: A sensory overload occurs when a person is unable to process all the sensory information around them. This can result in extreme anxiety or even a shutdown, where the individual becomes non-responsive to their surroundings as a coping mechanism.

Impact on Daily Life Sensory sensitivities can significantly affect an individual’s daily life, making activities like going to school, visiting a new place, or even eating certain foods challenging. To accommodate these needs, caregivers may use tools like noise-canceling headphones, weighted blankets, or sensory-friendly spaces to create a more comfortable environment.

 

 

How to Support Individuals with Autism

Understanding the core symptoms of autism is crucial for offering support and creating an inclusive environment. Here are a few strategies to help:

  • Communicate Clearly: Use simple language and visual aids to make communication easier.
  • Respect Routines: Try to stick to routines and give advance notice of any changes.
  • Create Sensory-Friendly Spaces: Provide a calm environment with limited sensory triggers to make them feel more comfortable.
  • Encourage Interests: Embrace their focused interests, as they can be a source of comfort and joy.

Conclusion

Autism is a complex condition that affects each person differently. Understanding the three main symptoms—social communication challenges, repetitive behaviors, and sensory sensitivities—can help us better support individuals with autism. By recognizing these symptoms and creating a more inclusive environment, we can ensure that people with autism feel accepted, understood, and empowered to thrive in their unique way.
