Why They’re Not a Diagnostic Tool — And Why They Still Matter
Health and care professionals are often expected to understand a person’s needs quickly, sometimes with very limited background information. Short GP appointments, hospital assessments, home visits and urgent community contacts all place pressure on practitioners to gain an accurate picture of what the person can manage in the moment.
It is in these situations that the GEM States framework is often most misunderstood. GEM States offer real value for communication and rapport, yet they were never designed to diagnose dementia — and cannot determine the type or stage of dementia. Their real strength lies elsewhere: in helping professionals recognise how the person is processing information right now, so that interactions become safer, calmer and more effective.
Understanding What GEM States Can (and Cannot) Do
GEM States do not identify the type of dementia, cannot replace clinical tests, and do not correspond to disease stages or severity. They cannot be used to diagnose dementia, confirm a decline or determine prognosis. Diagnosis requires a clinical pathway, which may include memory clinic assessments, neuropsychology, and investigations such as MRI, CT or blood tests.
The GEM framework focuses instead on the person’s current abilities. It encourages professionals to notice how someone responds to information, environmental cues and stress. This moment-to-moment insight is often more helpful in real-world practice than a label or stage, especially when the diagnosis is unclear, mixed or still evolving.
Why This Matters in Brief Care Encounters
Many interactions with people living with dementia happen under time pressure. Professionals may have only a few minutes to judge how best to communicate, how quickly to move through information, and how to support the person to remain calm and involved. GEM States help by offering a quick, observational lens for:
- how much information the person can manage at one time
- whether instructions need breaking down into small steps
- how the person reacts to noise, movement or sensory input
- how stress or unfamiliar surroundings are affecting presentation
- whether more time, repetition or reassurance is needed
This kind of interpretation does not require a formal assessment. It simply requires attunement — noticing how the person is functioning in the moment and adapting the professional approach accordingly.
Working with Emotional and Factual Logic
Professionals often find that a person’s emotional response drives their understanding more strongly than factual information. This is especially relevant during capacity assessments, difficult conversations, and planning discussions. By observing the person’s current GEM-like presentation, practitioners can judge whether:
- the timing of the conversation is supportive
- the environment is helping or hindering understanding
- information should be simplified or paced differently
- stress or sensory overload is affecting decision-making
This does not replace the Mental Capacity Act. Rather, it supports practitioners to create the conditions in which the person is most able to participate meaningfully.
Practical Benefits Across Services
GEM States provide a gentle, strengths-based way for professionals to interpret behaviour and ability during:
- GP appointments and medication reviews
- paramedic visits and urgent home assessments
- hospital care and ward-based interactions
- district nursing visits
- social work assessments
- community support and wellbeing services
They help prevent misinterpretations — such as assuming a person is “refusing”, “not engaging”, or “being difficult” — when the real issue is sensory overload, fatigue or difficulty processing information.
Working with the Person in Front of Us
At its heart, the GEM framework is about connection. It shifts the focus from what has been lost to what remains possible. Many professionals already use this kind of attuned practice instinctively; GEM States simply provide language and structure to support that intuition.
When combined with a gentle, sensory-aware way of approaching a person, the GEM framework becomes even more effective. This kind of approach naturally creates a small pause — a moment where the person can settle, orient themselves and feel safe. In that brief window, practitioners can quietly observe how the person is processing information, how they respond to visual or verbal cues and what their current GEM-like presentation might be. Used together, these tools support calmer interactions, clearer communication and a better experience for everyone involved.
GEM States will never diagnose dementia — but they will help us meet the person where they are. In busy services, pressured appointments and unfamiliar environments, this is what makes the difference between a task-centred interaction and a truly person-centred one.
If you would like to learn more about the GEMS States, please note that the dementia training sessions are currently available free of charge for anyone supporting a person living with dementia, including health and care professionals, thanks to National Lottery Funding until Summer 2027.
Summary
- GEM States are not a diagnostic tool and cannot identify the type or stage of dementia.
- The framework focuses on current abilities and processing, not pathology.
- It supports communication in brief appointments and busy environments.
- It helps professionals adjust pace, expectation and sensory load.
- Used alongside a gentle physical approach, it supports calmer, clearer interactions.
