Introduction
When a loved one begins to show signs of memory loss, confusion, or difficulty making decisions, families often assume it’s simply dementia. However, in domiciliary care (home care), understanding the difference between dementia and mental capacity is crucial — not just for your loved one’s well-being, but also to ensure their rights are respected and protected.
At Love and Care, we often get asked:
“Does dementia mean someone automatically loses mental capacity?”
“Can carers make decisions on behalf of someone with memory loss?”
“Does dementia mean someone automatically loses mental capacity?” “Can carers make decisions on behalf of someone with memory loss?”The short answer? No — and it’s important you understand why.
What Is Mental Capacity?
Mental capacity is a legal term that refers to a person’s ability to understand, retain, and weigh up information in order to make decisions for themselves.
The Mental Capacity Act 2005 protects individuals in England and Wales and sets out how decisions should be made when someone lacks capacity.
A person has capacity if they can:
-
Understand information relevant to the decision.
-
Retain that information long enough to make the decision.
-
Weigh up the pros and cons to reach a choice.
-
Communicate their decision in any way (not just verbally).
Just because someone has dementia, doesn’t mean they automatically lack capacity.
What Is Dementia?
Dementia is a progressive condition that affects memory, thinking, and behaviour. Common types include Alzheimer’s, Vascular Dementia, Lewy Body Dementia and more.
Symptoms vary hugely between individuals and can fluctuate daily.
Early stages often allow people to retain mental capacity for most decisions.
Mental Capacity vs. Dementia: Why Does It Matter in Home Care?
Capacity Is Decision-SpecificA person with dementia may be perfectly capable of deciding what they want for lunch but might struggle to understand the complexities of managing finances. In domiciliary care, capacity must be assessed per decision — not based on diagnosis alone.
Fluctuating CapacityCapacity can change from day to day, hour to hour — especially with dementia. A person may have capacity in the morning but struggle later in the day due to confusion or fatigue (known as sundowning).
Carers Cannot AssumeIn domiciliary care, carers cannot make decisions for clients unless it’s been legally established they lack capacity for that specific issue. Even then, decisions must always be made in the person’s best interests, following the law.
What Families Using Home Care Need to Know:
Assessments MatterIf there are concerns about capacity, a formal capacity assessment should be carried out by a trained professional — often a social worker, nurse, or GP. Home care providers can raise concerns but cannot assess capacity themselves unless specifically trained.
LPA and Best InterestsIf someone lacks capacity for certain decisions, a Lasting Power of Attorney (LPA) may allow a family member to act on their behalf. Where no LPA exists, care providers must follow the best interests process under the Mental Capacity Act.
Safeguarding and the CQCThe CQC (Care Quality Commission) monitors how home care providers uphold people’s rights under the Mental Capacity Act. Families should feel confident asking how a provider protects mental capacity and supports decision-making.
Red Flags to Watch For in Home Care
If you hear statements like:
-
“We make all the decisions for them because of their dementia.”
-
“They don’t need to be asked anymore, they’re confused.”
-
“We’ve just carried on as normal; there’s no point explaining.”
These may indicate poor practice and potentially breach the Mental Capacity Act.
