Co-Occurring Conditions and 

Specific Learning Differences (SpLD)

What is a Co-Occurring Condition?

ADHD, Autism, Learning Difficulties, etc. are neurodevelopmental conditions; that is to say, its symptoms, and associated behaviours and traits are the result of a person’s brain developing differently during the key stages of development before they were born or as a very young child. 

Conditions are said to co-occur when they are found in the same person at the same time. This is different from co-morbidity, which implies that the conditions are unrelated. Neurodiverse conditions co-occur at very high rates. For example: Approximately 1 in 2 people with ADHD have dyslexia, Approximately 1 in 2 people with ADHD have dyspraxia, 9 in 10 people with Tourette's have ADHD, 2 in 3 people with ADHD have autistic spectrum traits, and people with ADHD are 8-fold more likely to meet full criteria for an autistic spectrum diagnosis (From 'Neurodevelopmental conditions' on ADHDaware.org.uk, as of May 2024)

Examples of Co-occurring conditions are: Sensory Processing Disorder (SPD), Tourettes, Anxiety, Obsessive Compulsive Disorder (OCD), Developmental Language Disorder (DLD)

What is an SpLD?

A specific learning difficulty (SpLD) means that someone has a difference or difficulty with one or more certain parts of learning. Having a SpLD does not mean that children and young people cannot achieve and succeed in learning. Some examples of SpLD are: Dyslexia, Dyscalculia, Dysgraphia, Dyspraxia or Developmental Coordination Disorder (DCD). SpLDs are thought to affect at least 10% of the population. 

SpLDs affect the way information is processed and learned, which can have a very significant impact on formal education and study, and subsequently often on self-confidence as well. However, SpLDs are neurological and are unrelated to intellectual ability, socio-economic or language background. Students with SpLD can have significant compensatory strengths in other areas of study and can be creative and innovative thinkers.

Sensory Processing Disorder (SPD)

Sensory Processing Disorder (SPD) is a term used to describe children who struggle to correctly perceive the sensory world around them. 


SPD can be present in many forms and can often result in behavioural issues as well as functional difficulties. It is common for children within the Autistic Spectrum to experience many complex sensory difficulties. Children with SPD may experience sensory difficulties relating to one or multiple senses. Some of the symptoms of SPD are: Poor posture; Difficulty controlling movements; Poor handwriting; Dislikes loud noises; Difficulty making friends; Difficulty dressing, eating or sleeping; Frequently throws tantrums or gets upset; Easily distracted; Fidgety

Developmental Language Disorder (DLD)

1 out 15 people in the UK have a hidden but common condition (disability) called Developmental Language Disorder (DLD) and they feel invisible. That’s the equivalent of two children in the average classroom. 

DLD is a diagnosis given by a speech and language therapist to people who have lifelong difficulties with talking and understanding words. These difficulties create barriers to communication or learning in everyday life and aren’t due to another condition. 

Examples of how we support DLD

Dyslexia

Dyslexia mainly affects literacy and language-related skills. It is characterised by weaknesses in the fluency and accuracy of reading and writing and in the speed and quantity of information which can be processed at any one time. There might also be difficulties with aspects of fluency, organisation of ideas and sequencing in reading, writing, and, in some cases, speaking. 

Examples of how we support Dyslexia

Dysgraphia

Dysgraphia is a neurological condition that can affect written expression and fine motor skills. Not to be confused with similarly-sounding dyslexia, dysgraphia affects a person’s ability to organize and express thoughts and ideas in written form.

Writing is more than just putting pen to paper! Your brain needs to compute a complex set of instructions to process language in your mind, and then send those messages to your muscles in your hand and out onto the page, letter by letter.

Dysgraphia: from dys- ‘difficult’ + Greek -graphia ‘writing’.

Examples of how we support pupils with Dysgraphia:

Dyspraxia or Developmental Coordination Disorder (DCD)

Dyspraxia/Developmental Co-ordination Disorder (DCD) is characterised at its core by needs or underdevelopment in fine and/or gross motor co-ordination, but also by difficulties with organisation skills and sometimes visual perception. This can result in problems with writing by hand, concentration, personal and work organisation, time management and social difficulties.
