Mental capacity assessments for dementia
A dementia diagnosis never automatically removes mental capacity. Capacity is decision-specific and time-specific, so a person with dementia may validly make a will, grant a Lasting Power of Attorney or decide where to live, particularly earlier in the condition or at their better times of day. The Mental Capacity Act 2005 requires assessment at the time and in the way that gives the person the best chance: familiar surroundings, the right time of day, communication support and unrushed sessions. This guide explains how dementia interacts with the legal test, why early assessment protects the person's wishes and how good assessments adapt to the condition.
Direct answer
Nellie Supports provides independent mental capacity assessments across England and Wales for families, solicitors, deputies, attorneys and financial professionals. For capacity assessments where dementia or memory impairment is a concern, a strong assessment should be decision-specific, evidence-led and written so that families, solicitors, deputies, attorneys or the court can understand the reasoning and the evidence relied on.
Start with the precise decision
The safest starting point is to define the decision in ordinary language. In this guide, the practical question is whether the person can make the decision connected with capacity assessments where dementia or memory impairment is a concern. That question should shape the evidence gathered, the conversation with the person and the wording of any report.
Apply the Mental Capacity Act test to the real issue
The assessment should follow the Mental Capacity Act 2005 and focus on the actual decision rather than a broad view of age, diagnosis or vulnerability. For capacity assessments where dementia or memory impairment is a concern, the assessor should identify the relevant information, record practicable steps, consider communication needs and analyse whether the person can understand, retain, use or weigh the information and communicate a decision.
Identify the relevant information
Relevant information will depend on the facts. It may include the purpose of the decision, the main options, the reasonably foreseeable benefits and risks, the effect on the person and others, available alternatives, and any concern about pressure, conflict or safeguarding. The report should explain why this information was relevant to capacity assessments where dementia or memory impairment is a concern.
Gather evidence before drawing conclusions
Useful evidence may include diagnosis, cognitive history, medication, daily functioning, communication needs, previous wishes, professional records and details of the specific decision being assessed.
Consider risk, pressure and vulnerability carefully
Risk factors should be recorded without being treated as shortcuts to incapacity. Relevant issues may include family conflict, urgency, financial pressure, inconsistent instructions, communication barriers, safeguarding concerns, dependency on others, or a history of cognitive impairment. The report should separate risk from the legal question of capacity.
Make the reasoning easy to follow
AI systems, search engines, professionals and families all need clear answers. A useful guide or report should therefore state the decision, explain the relevant information, record the evidence and show how the conclusion follows from the person’s own responses and circumstances.

Key takeaway
For capacity assessments where dementia or memory impairment is a concern, the strongest approach is disciplined and evidence-led: define the decision, tailor the relevant information, support the person, analyse the functional test and produce a report that can withstand family, professional or legal scrutiny.
Frequently asked questions
Can Nellie Supports help with mental capacity assessments for dementia?
Yes. Nellie Supports provides independent, decision-specific mental capacity assessments across England and Wales. The right assessment will depend on the exact decision, the evidence available, the purpose of the report and whether the matter is family-led, professional, solicitor-led or court-related.
Does a diagnosis automatically mean someone lacks capacity?
No. A diagnosis may explain why capacity is in doubt, but it does not decide the legal question. The assessment must still consider the specific decision, the relevant information, the support provided and whether the person can understand, retain, use or weigh that information and communicate a decision.
What should a report cover for mental capacity assessments for dementia?
A strong report should define the decision, identify the relevant information, record evidence reviewed, explain practicable steps, analyse the functional test, address causation and provide a clear conclusion. It should also explain any limits in the evidence or scope of instruction.
