Co-occurring Conditions

Dyslexia and many other learning difficulties do not always occur in isolation.  It is quite common for an individual to have co-occurring conditions.  This can create challenges for accurate diagnosis.  However, appropriate identification of all the educational needs of an individual is vital as this enables the implementation of a range of suitable interventions.

Conditions which can sometimes co-occur with dyslexia are:

  • Dyscalculia is a specific learning difficulty in learning and comprehending mathematics.
  • Dyspraxia or Developmental Co-ordinator Disorder (DCD) is a specific difficulty with movement and aspects of learning such as thinking out, planning and carrying out sensory / motor tasks.
  • ADD and ADHD (Attention Deficit Disorder, with or without Hyperactivity) is a condition causing persistent difficulties with one or more of the following behaviours: inattention, hyperactivity and impulsivity.
  • Asperger Syndrome is a pervasive developmental disorder at the high functioning end of the Autistic Spectrum which can cause significant difficulties with social interaction, communication and flexible thinking.
  • Specific Language Impairment (SLI) affects communication. Often there are difficulties in language comprehension, expressive language, using language in everyday situations and speech-sound difficulties.

DAI is a member of the Spectrum Alliance (, a network of disability groups which was established to raise awareness of related developmental disorders (hidden disabilities) such as Dyslexia, Dyspraxia, ADHD and Asperger Syndrome.  It is quite common for an individual to have more than one of these life-long conditions.  Through the Spectrum Alliance we work towards increasing awareness of the co-morbidity of these conditions.
