Worsening Memory: Son Concerned About Mother

Clinical Scenario

Edith Lawson's son calls about his 79-year-old mother who has vascular dementia diagnosed 3 years ago. He reports significant deterioration over recent months: she is leaving the gas on, forgetting to eat, becoming confused about day and night, and has been found wandering outside in her nightdress. She lives alone since her husband died 2 years ago. Her son lives 30 minutes away and visits twice weekly. She has declined a care package previously, insisting she is fine. He is exhausted, worried, and feels guilty about not being able to do more.

What This Case Tests

Assessing dementia progression through a family informant; identifying safeguarding concerns (self-neglect, wandering, gas safety); evaluating capacity and best interests when a patient refuses help; coordinating a multidisciplinary care response; supporting the family carer who is under significant strain.

Common Mistakes Trainees Make

The three most common mistakes are: focusing only on the medical management of dementia without addressing the immediate safety concerns (leaving gas on and wandering are urgent risks), accepting the patient's refusal of a care package without assessing her capacity to make that decision, and not recognising the safeguarding dimension — Edith's situation constitutes self-neglect, which is a category of adult safeguarding.

The Consultation Challenge

This case has layers of urgency. The immediate safety risks (gas left on, wandering) require action today. The longer-term care planning requires coordination. And the son's wellbeing needs attention too.

Start with the safety assessment. The gas being left on is a fire and carbon monoxide risk. Wandering outside in nightclothes suggests disorientation and vulnerability to hypothermia, falls, and exploitation. These are not "dementia progression to monitor" — they are immediate safeguarding concerns that require intervention.

Assess Edith's capacity. She has previously declined a care package, but capacity is decision-specific and time-specific. A patient with progressing dementia who was capacitous 6 months ago may not be capacitous now. If Edith lacks capacity to understand the risks of living alone without support, a best interests decision involving the multidisciplinary team is appropriate. This does not mean overriding her wishes — it means ensuring her safety while respecting her preferences as far as possible.

The safeguarding dimension: self-neglect (not eating, not maintaining personal safety) in a vulnerable adult with dementia is a safeguarding concern under the Care Act 2014. Consider whether an adult safeguarding referral is appropriate. This is not about blaming Edith — it is about triggering a coordinated multi-agency response to keep her safe.

Coordinate the care response: urgent social services referral for needs assessment, occupational therapy for home safety assessment (gas isolation, door alarms, lighting), consider a carers' assessment for the son, expedite Edith's memory clinic follow-up to reassess her dementia stage, and discuss ongoing care options (increased domiciliary care, sheltered housing, residential care).

Address the son's wellbeing. He is exhausted and guilty. Validate his efforts, explain his legal right to a carer's assessment, and signpost to Dementia UK, Alzheimer's Society, and local carer support services. He cannot care for his mother sustainably without support.

Time check: Spend the first 4 minutes on the safety assessment and deterioration timeline. By minute 6, discuss capacity and the safeguarding concerns. Use minutes 7-10 for coordinating the care response and immediate safety measures. Reserve the final 2 minutes for supporting the son.

How Examiners Mark This Case

Data Gathering and Diagnosis: Examiners assess whether you take a thorough history of the deterioration from the son (timeline, specific incidents, baseline versus current function), identify the immediate safety risks (gas, wandering, self-neglect), screen for reversible causes of worsening (infection, medication changes, depression), and assess Edith's current support structure. The key is recognising that this is not just a "dementia is getting worse" conversation — it is a safeguarding and capacity situation.

Clinical Management and Medical Complexity: Examiners expect an immediate safety plan (gas isolation, consider telecare/door alarms), a social services referral for needs assessment, consideration of an adult safeguarding referral for self-neglect, and capacity assessment planning under the Mental Capacity Act. They also look for expediting the memory clinic review and coordinating multidisciplinary input. A trainee who simply refers to the memory clinic without addressing the immediate risks will score poorly.

Relating to Others: Examiners assess whether you validate the son's exhaustion and guilt, explain the legal frameworks in accessible language, and create a sense of shared responsibility — the son should not feel that he alone is responsible for his mother's safety. The consultation should feel like building a team around Edith, not adding to her son's burden.

Example Opening

Strong opening: "Thank you for calling — I can hear how worried you are about your mum, and I want you to know that what you're describing is something we need to act on. Let me ask you some specific questions about what's been happening, and then we'll put a plan together."

When discussing safeguarding: "What you're describing — the gas being left on, the wandering, not eating properly — these are safety concerns that we need to address urgently. This isn't about taking away your mum's independence. It's about making sure she's safe while we work out the right level of support."

When supporting the son: "I can see you're doing an incredible amount for your mum, and I want to make sure you're being looked after too. You have a legal right to support as a carer, and there are services that can help share the load. You can't do this alone — and you shouldn't have to."

Avoid: "She'll probably need to go into a home." (Premature, distressing, and does not explore the full range of options).

How This Appears in the SCA

This case tests the intersection of dementia management, safeguarding, capacity assessment, and family support. Examiners assess whether you recognise the immediate safety risks, understand the legal framework (Mental Capacity Act, Care Act), and can coordinate a multi-agency response while supporting the family carer.

Key Statistic

Approximately 60% of people with dementia live in the community, and one-third live alone. Wandering affects approximately 40% of people with dementia and is associated with falls, hypothermia, and premature institutionalisation. The average family carer of a person with dementia provides 40+ hours of care per week.

Frequently Asked Questions

When does worsening dementia become a safeguarding concern?

Self-neglect — failing to maintain adequate nutrition, personal hygiene, or environmental safety — is a recognised category of adult safeguarding under the Care Act 2014. When a person with dementia is leaving gas on, wandering, or not eating, these are immediate safety risks that may warrant a safeguarding referral. The purpose is not to remove autonomy but to trigger a coordinated multi-agency response to reduce risk.

How do I assess capacity in a patient with dementia who refuses help?

Capacity is decision-specific and time-specific under the Mental Capacity Act 2005. A person lacks capacity for a specific decision if they cannot understand the relevant information, retain it long enough to make the decision, weigh it up, or communicate their decision. Previous refusal of a care package may have been capacitous, but progression of dementia may mean she can no longer understand the risks. A formal capacity assessment should be conducted, ideally face-to-face, and documented thoroughly.

What immediate safety measures can I put in place for someone with dementia living alone?

Practical measures include: gas isolation or a gas safety device (British Gas offers a free service for vulnerable customers), telecare with pendant alarm and door sensors, medication blister packs with pharmacy supervision, a key safe for carer access, improved lighting, removal of trip hazards, and a referral for occupational therapy home assessment. These can often be arranged rapidly through social services or voluntary organisations.

What support is available for the family carer?

Under the Care Act 2014, carers have a legal right to a needs assessment from the local authority. Support includes: respite care (regular breaks from caring), Dementia UK Admiral Nurses (specialist dementia support), Alzheimer's Society helpline and local support groups, Carers UK for benefits advice and practical support, and GP follow-up for the carer's own physical and mental health. Many carers are unaware of these entitlements.

How do I coordinate a multi-agency response for a deteriorating dementia patient?

Key referrals include: social services (needs assessment and care package), occupational therapy (home safety assessment), community mental health team or memory clinic (dementia stage reassessment), and adult safeguarding if self-neglect criteria are met. In primary care, you are the coordinator — bring the agencies together around the patient. A multidisciplinary team meeting (virtual or in person) may be appropriate for complex cases. Document your coordination role clearly.
