Symptoms Of Asperger’s Syndrome

Verified by World Mental Healthcare Association

Asperger’s syndrome (AS) is a neurodevelopmental disorder that falls under the autism spectrum disorder (ASD) 1 umbrella. The affected individual, child or adult, may have a variety of symptoms of Asperger’s syndrome—leading to a unique experience for each sufferer.

Therefore, identifying and understanding these symptoms is crucial to help people with Asperger’s syndrome navigate all aspects of their daily life, including work, relationships, and self-care.

Common Symptoms Of Asperger’s Syndrome

Research and clinical practice 2 categorise the common signs and main symptoms of Asperger’s syndrome into different domains, namely:

1. Social interaction

Individuals with AS experience several difficulties in social interaction and communication, such as:

  • Difficulty in understanding social cues
  • Challenges in maintaining friendships
  • Difficulty in engaging in or sustaining reciprocal communication
  • Impaired understanding of others’ emotions or perspectives
  • Difficulty with nonverbal communication
  • Limited or narrow range of social interests or activities
  • Difficulty with understanding social norms, rules, and expectations
  • Difficulty with empathy or perspective-taking
  • Social awkwardness

2. Restricted and repetitive behaviours

People with symptoms of Asperger’s syndrome often adhere to rigid and repetitive behavioural patterns like:

  • Repetitive movements (such as rocking, hand flapping, spinning, etc.)
  • Adherence to strict routines and fixation on specific rituals
  • Highly focused and intense interests in specific topics or activities
  • Difficulty with imaginative play and lack of interest in peer activities
  • Difficulty in adapting to new and unfamiliar situations
  • Engagement in repetitive or stereotyped behaviours (such as lining up objects, stacking items, or repeating certain phrases)
  • Resistance to changes in environment or routines
  • Inflexibility or rigidity in thinking

3. Sensory sensitivities

The symptoms of Asperger’s syndrome related to poor sensory processing include:

  • Hypersensitivity or hyposensitivity to sensory stimuli, such as lights, sounds, textures, tastes, or smells
  • Overwhelming response or aversion to certain sensory inputs
  • Sensory overload and sensory-seeking behaviours (like reacting to bright lights, loud noises, certain textures, etc.)
  • Sensory sensitivities manifesting in various ways (such as covering ears, avoiding bright lights or loud noises, etc.)

4. Speech and language

People with Asperger’s syndrome experience several speech and language issues, like:

  • Atypical speech patterns
  • Pragmatic language difficulties (such as understanding social cues, sarcasm, humour, etc.)
  • Delayed or impaired speech and language development in early childhood
  • Limited use of gestures or facial expressions to convey emotions or meanings
  • Echolalia or repetitive use of words or phrases from other sources, without understanding their meaning
  • Difficulty with using and understanding nonverbal communication, such as body language, facial expressions, and tone of voice
  • Maintaining eye contact or an appropriate tone of voice while conversing

5. Motor coordination

Individuals with AS tend to experience motor coordination difficulties that impact activities of daily living, sports, or other physical activities. These include:

  • Impaired coordination or clumsiness
  • Difficulty with fine or gross motor skills (such as tying shoelaces, using utensils, or catching a ball)
  • Challenges with handwriting or other fine motor tasks
  • Difficulty with physical coordination, balance, or spatial awareness

6. Emotional regulation

People with Asperger’s syndrome experience emotional dysfunction, such as:

  • Difficulty in recognizing, understanding, or regulating emotions
  • Emotional meltdowns or outbursts in response to sensory overload
  • Difficulty with coping skills, self-regulation, or emotional flexibility
  • Challenges with managing frustration, anger, anxiety, or stress
  • Emotional regulation difficulties may result in mood swings, emotional sensitivity, or difficulties in social situations

Asperger’s Syndrome In Children

Symptoms of Asperger’s syndrome in children typically manifest in early childhood (usually around the age of 2-3 years) and may vary in severity and presentation among individuals. Some common symptoms 3 include:

  1. Difficulties with social interaction and communication
  2. Repetitive behaviours and rigid routines
  3. Problems in understanding social cues, nonverbal communication, and maintaining friendships
  4. Limited interests or preoccupations with specific topics
  5. Speech difficulties, including speaking in a formal or monotone manner
  6. Motor coordination challenges
  7. sensory sensitivities
  8. Poor emotional regulation

However, it’s important to note that not all children with Asperger’s syndrome would exhibit the same symptoms, and the severity and presentation of symptoms may vary widely. Some children may have mild Asperger’s symptoms, while others may experience more significant challenges that affect their social, academic, and emotional well-being.

Signs Of Asperger’s In Adults

Asperger’s symptoms in adults may continue from childhood or may present themselves for the first time in adulthood. Common symptoms 4 include:

  • Difficulties in social interaction
  • Communication challenges
  • Rigid rituals and routines
  • Sensory processing issues
  • Relationship difficulties and employment challenges
  • Intense interests and special obsessions
  • Difficulties in emotional regulation
  • Impaired speech
  • Low self-esteem and confidence
  • High levels of depression and anxiety

Much like the AS symptoms in children, Asperger’s symptoms in women and men also display a wide variation. Some individuals may even have 5 high-functioning Asperger’s symptoms. Nonetheless, understanding and managing these symptoms can be crucial for affected adults to thrive in various aspects of their daily life, including work, relationships, and self-care.

How To Identify Asperger’s Syndrome

It’s important to note that individuals with Asperger’s syndrome may present with varying degrees of severity and combinations of the aforementioned symptoms.

Identifying the signs 6 and symptoms of Asperger’s syndrome can be done through careful observation and assessment by qualified healthcare professionals or specialists in neurodevelopmental disorders.

Asperger’s syndrome was once considered a separate diagnosis within the autism spectrum, but it is now classified as part of the broader autism spectrum disorder (ASD) 7 in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).

To receive a diagnosis of Asperger’s syndrome, an individual must meet specific diagnostic criteria outlined in the DSM-5. The evaluation process for Asperger’s syndrome often includes a physical exam, interviews, questionnaires, behavioural observations, and standardised assessments.


If you notice symptoms of AS in your child or loved one, it’s important to seek professional help for a proper diagnosis and prompt treatment. Consulting a doctor or mental health professional can provide valuable insights and support. With timely intervention, individuals with ASD can receive effective treatment and support to manage their symptoms and lead healthier lives.
