Cognitive communication disorders are defined as “acquired deficits in communication that arise from an underlying cognitive impairment”. 

The subsequent communication difficulties can be wide-ranging. These can affect auditory comprehension, verbal expression, reading, writing, non-verbal communication, pragmatics, discourse and social communication.

They result from acquired deficits in cognition including attention, memory, information processing, reasoning, problem-solving and executive functions or self-regulation.

CCD’s are varied and complex. The role of SLTs in supporting adults, young people and children with acquired CCD’s is well-recognised and descriptions of evidence-based assessment and intervention approaches are well-documented.

Signs and Symptoms

Signs and symptoms of cognitive communication disorders vary between individuals, according to their profile of underlying cognitive function. However, signs and symptoms may include.

  • difficulty understanding complex or lengthy spoken or written information
  • reduced recall of spoken and written information, personal stories, or personal information shared by their communication partner
  • reduced initiation, elaboration, and maintenance of conversation or social interaction
  • altered affect including blunt, flat, or inappropriate affect
  • word-finding difficulties or difficulties learning new vocabulary
  • verbosity
  • tangential topic production
  • reduced turn-taking in conversations
  • unstructured or disorganised discourse production
  • repetitiveness
  • omission of details and information
  • increased processing time for understanding spoken and written information and/or formulating what to say or write
  • reduced inhibition of responses and personal disclosures that are considered less socially acceptable
  • difficulty interpreting emotions and social cues
  • difficulty using non-verbal communication that matches the topic and context
  • reduced ability to monitor self, communication partners and conversation topic

Impact of CCDs

Cognitive communication disorders can have a significant and debilitating impact on family, social, community, educational and vocational life for people with cognitive communication disorders, as well as impacting their families, friends and wider networks.

These impacts are primarily related to increased communication challenges and breakdowns between the person with a CCD and their communication partners.

People are often adversely impacted int the following ways:

Relationships and social participation
Cognitive communication disorders can make it harder to build and maintain relationships, leading to shrinking social networks, isolation, and reduced participation in leisure activities, affecting both the person and their wider support network.

Education and work
These disorders often affect the communication skills needed at school or work, contributing to poorer academic outcomes and a reduced likelihood of returning to work after injury. Research consistently shows that cognitive-communication skills. particularly verbal reasoning, problem-solving, social inference and sustained attention, are strong predictors of return-to-work outcomes after TBI.

Autonomy and independence
People may become more reliant on family and carers, and can be at risk of being excluded from decisions about their own lives as others step in to help.

Identity and roles
A cognitive communication disorder can disrupt a person’s sense of self and shift key life roles as a partner, parent, colleague or friend, for both the individual and their family.

Mental health and wellbeing
Common consequences include loneliness, loss of confidence, and reduced quality of life, alongside increased strain on family members and carers.

Long-term consequences

  • Children are especially vulnerable, as untreated difficulties can compound over time, affecting development, peer relationships, and classroom behaviour. Younger age at injury is linked to greater long-term impact.
  • Criminal justice involvement: Rates of traumatic brain injury are notably high among both young and adult offender populations, and cognitive communication disorders may increase vulnerability to poor decision-making, manipulation, and difficulty navigating legal processes, contributing to poorer outcomes and higher re-offending risk.
