The Illusion of "Object Permanence" in ADHD: Implications for Older Adults Living with Dementia in Care Homes

1. Introduction

Within the adult ADHD community, the phrase "object permanence" has been widely adopted to describe a profound and pervasive experience: when an object, task, or even a person leaves the individual's visual field, it ceases to exist in their active awareness [1]. While developmental psychologists correctly note that this is not a failure of Piagetian object permanence (the infant understanding that hidden objects still exist), the colloquial use of the term captures a very real neurological phenomenon rooted in executive dysfunction [2].

For older adults living with ADHD, particularly those who also experience cognitive decline or dementia, this reliance on visual cues becomes a critical lifeline. In residential care settings, however, the standard approach to environmental management often prioritises a tidy, uncluttered aesthetic. This paper explores the intersection of ADHD, working memory, and the care home environment, arguing that the removal of visible personal possessions constitutes a threat to personhood and a safeguarding issue for residents living with ADHD and dementia.

2. The Neurological Basis of "Out of Sight, Out of Mind"

2.1 Working Memory and Executive Function

The phenomenon described as a lack of "object permanence" in ADHD is more accurately understood as a deficit in working memory and attentional regulation [1] [2]. Working memory acts as the brain's short-term workspace, holding information temporarily so it can be manipulated and acted upon [3]. In individuals with ADHD, working memory is often significantly impaired, meaning that without continuous sensory input, information quickly drops out of active awareness [1] [2].

Russell Barkley, a leading expert on ADHD, conceptualises the disorder primarily as one of self-regulation and executive functioning [4]. Barkley notes that working memory allows individuals to hold a goal in mind in the absence of an external cue [5]. When this internal system falters, as it does in ADHD, the individual becomes heavily reliant on the external environment to prompt behaviour and maintain awareness [4] [6].

2.2 Prospective Memory and External Scaffolding

Prospective memory (the ability to remember to execute an intention in the future) is also compromised in ADHD [3] [7]. While neurotypical individuals might rely on internal time-monitoring (time-based prospective memory), those with ADHD perform significantly better when intentions are tied to visual or environmental cues (event-based prospective memory) [3] [7].

Consequently, individuals with ADHD frequently engage in "external cognition" or "behavioural scaffolding" [6] [8]. They offload cognitive tasks onto their environment, using visible objects as a functional memory system [2] [8]. A pile of laundry on the floor, medication left on the counter, or keys placed by the door are not merely signs of disorganisation; they are deliberate, albeit sometimes chaotic, strategies to bypass working memory deficits [2].

3. The Functional Value of "Clutter" vs. Hoarding

It is crucial to distinguish between the functional "clutter" of ADHD and the pathology of Hoarding Disorder (HD), though the two can co-occur [9].

In HD, the accumulation of items is driven by an intense urge to save, strong emotional attachments to the objects, and significant distress at the prospect of discarding them [10]. Conversely, the visible disorganisation seen in ADHD is often a direct result of executive dysfunction [10]. Items are left out because putting them away behind closed doors or in opaque containers removes them from the visual field, effectively erasing them from memory [2] [10].

For the ADHD brain, a tidy environment with everything stored out of sight is genuinely disabling. It strips away the external scaffolding required to navigate daily life, leading to missed medication, forgotten tasks, and profound disorientation [2].

4. The Care Home Context: A Clash of Needs

When older adults living with ADHD and dementia enter residential care, they encounter an environment designed around standard operating procedures that often conflict with their neurological needs.

4.1 The Disabling Effect of "Tidying"

Care home staff, motivated by hygiene, safety, and a desire to maintain a pleasant environment, frequently tidy residents' rooms. They put personal belongings into drawers, clear surfaces, and remove what they perceive as clutter. For a resident living with ADHD, this well-intentioned action is catastrophic. By hiding functional objects and personal possessions, staff are dismantling the resident's only effective memory and orientation system [2].

As Lee (2019) observed in an ethnographic study of care homes, people living with dementia are often excluded from decision-making regarding their personal possessions, and items are frequently removed without their knowledge or agreement [11]. When this happens to a resident who relies on visual cues due to ADHD, the resulting confusion, distress, and loss of independence are magnified.

4.2 Safeguarding and the Mental Capacity Act

The removal of personal possessions without consent raises significant safeguarding concerns. Under the Care Quality Commission (CQC) Regulation 9, care must be person-centred, meeting the individual's needs and reflecting their preferences [12]. Furthermore, the Mental Capacity Act 2005 stipulates that any decision made on behalf of someone lacking capacity must be in their best interests and represent the least restrictive option [13].

If a resident's "clutter" is, in fact, a necessary cognitive prosthetic, removing it without a thorough, individualised risk assessment and best interests decision is a violation of their rights. It constitutes a failure to provide person-centred care and may border on institutional abuse through the denial of necessary cognitive support.

4.3 Emotional Attachment and Personhood

Kitwood's seminal work on person-centred dementia care emphasises the importance of maintaining personhood: the standing or status bestowed upon one human being by others [14]. Personal possessions are intimately tied to identity and continuity of self [11]. For individuals with ADHD, objects often hold profound emotional significance, serving as tangible anchors to past memories and relationships [15]. Discarding items that appear to be "rubbish" to staff, but hold deep meaning for the resident, can cause immense psychological harm and erode their sense of identity.

5. Practical Strategies for Care Homes

To support residents living with co-occurring ADHD and dementia, care homes must adopt environments and practices that accommodate external cognition while balancing safety.

• Transparent storage: utilise clear bins, glass-fronted cabinets, and open shelving. This allows the resident to see their belongings while maintaining a level of organisation and hygiene [2].
• Strategic placement of functional objects: important items (mobility aids, glasses, familiar mementos) should be kept in the resident's direct line of sight, preferably at eye level [2].
• Collaborative risk assessments: rather than defaulting to removal, staff should work with the resident (and their advocates) to assess the actual risk of specific objects. The Material Citizenship framework suggests using functional objects as enablers to balance risk management with empowerment [11].
• Personalised visual cues: use meaningful visual prompts to aid wayfinding and memory, such as memory boxes at room thresholds or highly visible, personalised signage [16].
• Staff education on ADHD: staff must be trained to recognise that for some residents, a "messy" room is a functional room. They need to understand the difference between hoarding and ADHD-related visual organisation.

6. Integration into the ADHDementia Framework

The insights regarding working memory, external cognition, and the functional use of visual space must form a core component of the ADHDementia screening tool and training framework.

6.1 Screening Tool Enhancements

The screening tool should include specific questions designed to identify a lifelong reliance on visual organisation. Questions might include:

• "Has the individual historically preferred to keep important items out on surfaces rather than put away in drawers?"
• "Does the individual become distressed or disoriented when their belongings are moved or 'tidied' by others?"
• "Does the individual rely heavily on visual reminders (such as leaving items by the door) to remember tasks?"

6.2 Training Framework Modules

The commercial training framework should feature a dedicated module on "The Environment as Memory." This module will educate care staff on:

• The neurological reality behind the "object permanence" metaphor in ADHD.
• The concept of external cognition and why "clutter" is often a vital coping mechanism.
• The legal and ethical implications (CQC standards, Mental Capacity Act) of removing personal possessions.
• Practical, hands-on strategies for creating ADHD-friendly, dementia-inclusive physical spaces within the care home.

7. Conclusion

The colloquial concept of "object permanence" in ADHD highlights a critical vulnerability in working memory that necessitates external, visual scaffolding. For older adults living with dementia and ADHD in residential care, the standard practice of tidying and removing visible possessions actively disables them, stripping away their functional memory systems and threatening their personhood. By recognising visual organisation as a valid cognitive strategy rather than a behavioural problem, care homes can fulfil their legal and ethical safeguarding duties, providing truly person-centred care that honours the neurodivergent mind.
