Paediatric ASD Symptoms and Causes
At Dementech Neurosciences, our team of paediatric specialists understand the complexities of living with autism. We tailor the diagnostic assessments we use and suggest treatment plans around your specific needs and symptoms.
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that can affect how a child communicates, socialises, processes information and responds to the world around them. Every child experiences autism differently, which is why a personalised assessment is so important.
Some children may struggle with social interaction and communication, while others may experience sensory sensitivities, repetitive behaviours or difficulties adapting to change. In some cases, signs may become more noticeable as social and educational demands increase.
A private autism assessment can help families better understand their child’s strengths, challenges and support needs, while also providing clarity on the next steps available at home, school and beyond.
Children with autism can present in different ways, and signs can vary depending on age, personality and development. Some families seek support after noticing early developmental differences, while others may become concerned once their child starts nursery or school.
Common signs can include:
Social and Communication Differences
- Delayed speech or language development
- Difficulty maintaining conversations
- Limited eye contact
- Challenges understanding emotions or social cues
- Preferring solitary play
- Repetitive language or scripting phrases
Behavioural and Sensory Differences
- Strong preference for routines
- Distress around changes in routine
- Repetitive movements or behaviours
- Intense interests in specific topics
- Sensitivity to sounds, textures, lights or smells
- Difficulty regulating emotions
Experiencing one or more of these signs does not automatically mean a child is autistic. A professional child autism assessment helps build a clearer understanding of your child’s development and whether further support may be beneficial.

Private Paediatric ASD Diagnosis at Dementech

Our private ASD assessments are designed to provide families with a detailed understanding of their child’s development within a supportive and structured environment.
- Initial Parent Consultation
The assessment process begins with a detailed consultation where we discuss your child’s developmental history, communication, behaviour, learning and social interactions. We also explore any concerns raised by parents, teachers or healthcare professionals.
- Child Assessment Sessions
During the assessment, our specialists observe how your child communicates, responds socially, plays, processes information and reacts to different situations. Depending on your child’s needs, this may include structured activities, behavioural observations and age-appropriate developmental assessments.
We always aim to create a calm and comfortable environment where children feel supported throughout the process.
- School and Educational Input
Where appropriate, we may review feedback from your child’s nursery or school to build a broader understanding of how they interact in educational and social settings.
- Diagnostic Outcome and Recommendations
Following the assessment, families receive a detailed report outlining findings, recommendations and next steps. If a diagnosis of Autism Spectrum Disorder is made, we provide guidance on the support that may help your child both academically and emotionally.
Our team can also advise on educational support, therapy recommendations and referrals where needed.

“My family and I experienced one of the hardest times of our lives having to deal with my wife’s deteriorating condition. I would like to personally thank the lovely young lady Zobiaa from Dementech, for showering us with compassion, empathy and genuine care and concern. Her professionalism, high-level customer service and communication, eye for detail, and willingness to go the extra mile to accommodate our needs and make not only my wife, but our whole family, feel as comfortable and supported as possible, is something we will always be grateful for. Thank you so much for your friendly and polite presence Zobiaa and taking the time and effort to build a relationship with us. You really made our visits to the clinic a positive, 5 star experience.”

“Dementech Neurosciences is a relatively new clinic specialising in the scientific assessment and treatment of Parkinson’s Disease. It represents a significant development in the treatment of Parkinson’s and has done a great job of establishing itself and its reputation in a short period of time. The premises are extremely well situated in central London, the consultant neurologists are all at the top of their field in their specialisation of the treatment of Parkinson’s Disease, and the clinical and administrative staff are of a similar standard. The atmosphere of the clinic is positive and the results, in the short period of time I have been able to assess, have been similarly positive.”

“Have had nothing but kindness and professionalism from Dementech and all their staff. From their initial guidance by Shakeela, through to staff conducting the MRI tests and Dr. Lucio D’Anna for his expertise clarity of explanation, compassion and consideration. Special mention to Zobia, who saved the day with her quick thinking that helped my mother-in-law to obtain extended care. Overall a perfect experience. Cannot recommend them enough.”
