Do I Have Autism and ADHD? Understanding the Signs and Assessment Process

Many adults wonder if they might have autism, ADHD, or both conditions together. While online information can provide insights, it's important to understand that only a qualified healthcare professional can provide a proper diagnosis. This article will help you recognize common signs and understand the assessment process for both conditions.

Understanding Autism and ADHD

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterised by differences in social communication, sensory processing, and patterns of behaviour or interests. Autism exists on a spectrum, meaning it presents differently in each person.

Attention-Deficit/Hyperactivity Disorder (ADHD) involves persistent patterns of inattention, hyperactivity, and/or impulsivity that interfere with functioning or development. ADHD can present primarily as inattentive type, hyperactive-impulsive type, or combined type.

Common Signs of Autism in Adults

• Difficulties with social interactions and understanding unwritten social rules

• Challenges with back-and-forth conversation

• Strong, focused interests in specific topics

• Need for routine and difficulty with unexpected changes

• Sensory sensitivities (to sounds, lights, textures, etc.)

• Difficulty understanding others' perspectives or emotions

• Literal interpretation of language and difficulty with figurative expressions

Common Signs of ADHD in Adults

• Difficulty maintaining attention during tasks

• Frequent forgetfulness in daily activities

• Difficulty organising tasks and activities

• Often losing necessary items

• Easily distracted by external stimuli or unrelated thoughts

• Fidgeting or inability to stay seated when expected

• Talking excessively or interrupting others

• Difficulty waiting for your turn

When Autism and ADHD Occur Together

Research shows that autism and ADHD frequently co-occur, with up to 70% of autistic individuals also having ADHD symptoms. When both conditions are present, you might experience:

• Intense hyperfocus on special interests but difficulty focusing on other tasks

• Sensory sensitivities alongside restlessness

• Social communication challenges combined with impulsivity

• Executive functioning difficulties that affect organisation and daily functioning

• Emotional regulation challenges

Questions for you to Consider

While only a professional can diagnose these conditions, consider these questions:

For Autism:

• Do you find social situations exhausting or confusing?

• Do you have intense interests that you can focus on for hours?

• Are you sensitive to certain sensory inputs like bright lights or loud noises?

• Do you prefer routines and find unexpected changes difficult?

For ADHD:

• Do you struggle to stay focused on tasks that aren't interesting to you?

• Is it hard to organise your responsibilities and time?

• Do you often misplace important items?

• Do you feel restless or have racing thoughts?

The Professional Assessment Process

If you recognise several signs mentioned above, consider seeking a professional evaluation. The assessment process typically involves:

1. Initial screening - Often begins with questionnaires or rating scales

2. Comprehensive evaluation - May include:

   • Clinical interviews about your developmental history

   • Observation of behaviour

   • Cognitive and psychological testing

   • Input from family members or other people who know you well

   • Ruling out other conditions with similar symptoms

For autism, assessments might include specialised tools like the ADOS (Autism Diagnostic Observation Schedule) or ADI-R (Autism Diagnostic Interview-Revised). For ADHD, evaluations often include rating scales like the Conners rating scales and QbCheck.

Remember

Both autism and ADHD are neurodevelopmental differences, not character flaws or personal failings. Many successful, creative, and talented people have one or both of these conditions. Understanding your neurology can help you develop strategies that work with your brain rather than against it.

Whether or not you receive a formal diagnosis, understanding your unique cognitive style can lead to better self-awareness and life strategies that honour your authentic self.
