Distinguishing normal age-related forgetfulness from something that needs attention is difficult from inside a family. A structured cognitive assessment gives you a clear answer — and where there is a treatable cause, finding it early genuinely matters.
What is dementia?
Dementia is not a single disease but a group of conditions causing progressive decline in memory, thinking, language and the ability to manage everyday tasks. Alzheimer's disease is the most common cause; vascular, Lewy body and frontotemporal dementia are others, and they differ in how they present and progress.
Some memory change with age is normal. The distinction that matters is between forgetting where you put your keys and forgetting what keys are for, repeatedly asking the same question, or becoming lost in familiar places. Not all cognitive decline is dementia, which is a key reason to have it assessed properly: depression in older adults can closely mimic it, and thyroid problems, vitamin B12 deficiency, medication side effects and delirium can all cause reversible impairment.
What causes dementia?
The dementias have different underlying causes, and identifying which is present affects both what to expect and how it is managed. Several contributing factors are recognised, some of them modifiable:
- Age — the strongest single risk factor
- Family history, particularly where onset was early
- Cardiovascular factors: high blood pressure, diabetes, high cholesterol, smoking
- Previous stroke or small-vessel disease in the brain
- Significant or repeated head injury
- Long-standing heavy alcohol use
- Untreated depression in later life
Common symptoms
Symptoms vary between people, and you do not need to recognise all of these to benefit from an assessment.
- Memory loss disrupting daily life
- Difficulty with familiar tasks (cooking, finances)
- Confusion about time, place, or people
- Language struggles
- Misplacing items
- Mood or personality changes
When to seek help
If memory lapses or personality shifts exceed normal ageing and alter daily functioning, early evaluation provides access to early support strategies.
How dementia is diagnosed
Assessment has two purposes: establishing whether cognitive decline is genuinely beyond what ageing accounts for, and identifying reversible causes before concluding that a progressive dementia is responsible. It involves structured cognitive testing, a history of how difficulties began, and — with consent — an account from a family member, since the person affected may not be aware of the changes. Daily function is assessed specifically: managing money, medication, cooking, travel and personal care.
Blood tests are routinely requested to exclude thyroid dysfunction, vitamin B12 deficiency and other treatable causes, and brain imaging is often arranged. Depression is assessed carefully, because in older adults it can closely resemble dementia and improves substantially with treatment. Early, accurate diagnosis matters — it allows planning while the person can still take part in decisions about their own care.
Treatment options
Most dementias cannot be cured, but a great deal can be done to maintain function, manage symptoms and support both the person and the family. Treatment aims at quality of life, not only cognition.
Medication. Some medications modestly slow the progression of symptoms in certain dementias, particularly Alzheimer's disease, and their realistic benefits and limitations are explained honestly rather than overstated. Medications for agitation or distress are used cautiously and reviewed regularly, since some carry meaningful risks in older adults.
Managing behaviour and distress. Agitation, sleep disturbance and suspicion are often the hardest part for families. These usually have identifiable triggers — pain, infection, overstimulation, disrupted routine — and addressing the trigger is safer and more effective than sedation.
Treating what is treatable. Depression, anxiety, sleep problems, pain, hearing and vision impairment all worsen cognitive function and are treatable in their own right. Reviewing existing medication matters too, as several commonly prescribed drugs impair cognition in older adults.
Supporting the family. Caregiver strain is substantial and is addressed directly: practical guidance on communication, routine and managing difficult situations, along with attention to the carer's own health, since carer depression is common and often unrecognised.
What recovery looks like
Progressive dementias do not resolve. What realistic care achieves is slower functional decline, better management of distressing symptoms, fewer crises, and a person who remains comfortable and engaged for longer. Structure and familiarity help considerably: consistent routine, a familiar environment, corrected hearing and vision, and meaningful activity.
Early diagnosis allows practical and legal planning — financial arrangements, decisions about future care, conversations about preferences — while the person can still take part. Families consistently report this as one of the most valuable outcomes of early assessment.

Frequently asked questions
Occasionally forgetting a name and recalling it later is typical ageing. Difficulty with familiar tasks, confusion about time or place, and memory loss that disrupts daily life are not, and warrant assessment.
Yes. Some causes of cognitive decline are treatable — including thyroid problems, vitamin deficiencies, medication effects and depression. Where the diagnosis is dementia, early identification allows planning, support and management while the person can participate in decisions about their own care.
Practical guidance on managing behavioural changes, structuring the day, communication approaches, and looking after your own health. Caregiver strain is treated as a clinical concern in its own right.
Structured memory and reasoning tests, a detailed history from you and usually a family member, review of current medications, and screening for reversible causes. Referral for scans or blood tests is arranged where indicated.
Occasional forgetfulness — misplacing items, briefly forgetting a name — is ordinary at any age. Signs that warrant assessment include repeating the same question within a short period, getting lost in familiar places, difficulty managing money or medication, marked personality or behaviour change, and struggling with tasks that were previously routine. Any decline that is progressing or affecting daily function should be assessed.
The common progressive dementias, such as Alzheimer's disease, cannot currently be reversed. However, several conditions that cause similar symptoms can be — including depression, thyroid dysfunction, vitamin B12 deficiency, medication side effects and infection. Excluding these is a central purpose of assessment, and is one reason not to assume that memory problems are untreatable.
Yes, for several reasons. It excludes reversible causes; it identifies which type of dementia is present, which affects management; it gives access to treatments that may slow symptom progression; and it allows planning for finances, care and preferences while the person can still take part in those decisions. It also gives families an explanation for behaviour they may have been misinterpreting.
Caring for someone with dementia is demanding, and carer strain is taken seriously as part of the clinical picture. Practical guidance is provided on communication, managing difficult behaviour, establishing routine and planning ahead. The carer's own mental and physical health is reviewed too, since depression and exhaustion among carers are common and frequently overlooked.
