Abstract
This guide explains the cognition domain of the NHS Continuing Healthcare Decision Support Tool. It covers memory, orientation, comprehension, insight and awareness of risk, the significance of impaired safety awareness, the level of supervision required, the interaction with behaviour and communication, and the evidence that supports an accurate level.
The cognition domain in the CHC Decision Support Tool
Cognition covers memory, orientation, understanding and, most importantly for this domain, awareness of risk. Someone who cannot recognise danger requires a level of supervision that is frequently under-recorded.
What the domain covers
Memory, orientation to time, place and person, comprehension and processing, insight into their own condition and needs, decision making, and awareness of risk to themselves. It covers the supervision and prompting required as a result, and the skill involved in maintaining safety where awareness is impaired.
Awareness of risk is central
The most significant element is whether the person recognises danger. Someone who will attempt to walk despite being unable to, who does not recognise hot surfaces, who leaves the building without awareness of traffic, or who cannot recognise that they need medical attention, requires a level of supervision that goes well beyond prompting. That requirement is the need.
Supervision requirements
Record what supervision is actually required, in concrete terms. Constant supervision, checks at set intervals, waking night support, environmental measures and the number of staff involved all belong in the narrative. A statement that the person needs supervision, without frequency or intensity, gives an assessor almost nothing to work with.
Fluctuation
Cognition frequently fluctuates, both across a day and between days, and fluctuation goes directly to unpredictability in the four key characteristics analysis. Sundowning, post-infection delirium and variable lucidity are all significant and are routinely missed because assessments happen at one point in time, often when the person is at their best.
Interaction with other domains
Cognitive impairment affects almost everything else. It affects the ability to communicate needs, to eat safely, to take medication, to recognise pain, and to comply with treatment. Where impairment produces distress or resistance, the behaviour domain is engaged too. Describing those interactions is essential to the complexity element.
Evidence that helps
Cognitive assessments and any recorded scores, memory clinic and psychiatry letters, care records describing disorientation, wandering or unsafe behaviour, incident logs, records of supervision levels and staffing, capacity assessments where undertaken, and records of night time confusion held separately from daytime notes.
Key takeaway
The core of this domain is awareness of risk and the supervision it requires. Record supervision concretely with frequency and staffing, capture fluctuation across the day and night, and describe how cognitive impairment compounds nutrition, medication, communication and behaviour.

Frequently asked questions
Does a dementia diagnosis set the level?
No. Eligibility and domain levels rest on assessed needs rather than diagnosis. The level reflects the actual impairment, the risk it creates and the supervision required, not the condition name.
Can the cognition domain reach priority?
No. Only behaviour, breathing, drug therapies and medication, and altered states of consciousness carry a priority level. Cognition still contributes strongly to the overall picture and to complexity.
What if cognition varies day to day?
Record the range and the frequency, not the average. Fluctuation goes directly to unpredictability in the four key characteristics analysis and is one of the most commonly missed elements.
