Forgetting a name now and then can happen to anyone. Repeatedly forgetting recent conversations, becoming lost in familiar places or struggling with once-familiar tasks deserves closer attention.
Alzheimer’s disease is one possible explanation, but it is not the only one. An assessment can help identify what is happening and what support is needed.
What is Alzheimer’s disease?
Alzheimer’s is a progressive brain disease that damages nerve cells and their connections. It is associated with abnormal changes involving proteins called amyloid and tau. Over time, it can affect memory, reasoning, language, behaviour and the ability to manage everyday activities.
It is the most common cause of dementia. Dementia describes a pattern of cognitive difficulties severe enough to interfere with daily independence. Alzheimer’s names a particular disease that can cause that pattern.
Other causes include vascular disease, Lewy body disease and frontotemporal degeneration. A person can also have more than one contributing condition, often called mixed dementia. Alzheimer’s and dementia are therefore not interchangeable names for every memory problem.
Which symptoms should you know?
A common early feature is difficulty learning and remembering new information. Changes may include:
- Repeated questions or forgotten recent conversations.
- Trouble following familiar steps, planning or handling everyday finances.
- Difficulty finding words or following conversations.
- Becoming confused about dates or places.
- Getting lost or having trouble judging distances.
- Changes in judgement, confidence, mood or behaviour.
Symptoms usually develop gradually. As the disease progresses, a person may need more support with dressing, eating, communication and personal care. The pattern and pace differ between individuals.
Are there different types?
Alzheimer’s can be described in several ways. These categories overlap, rather than forming completely separate diseases.
Later-onset Alzheimer’s: Symptoms begin at age 65 or older. This is the more common presentation.
Younger-onset Alzheimer’s: Symptoms begin before age 65. It is also called early-onset Alzheimer’s. “Early-onset” refers to age, while “early-stage” refers to how far the disease has progressed. A person can have younger-onset disease at any stage.
Inherited forms: Rare changes in particular genes can cause Alzheimer’s to run strongly in a family, often with younger onset. Most people with Alzheimer’s do not have one of these rare inherited forms. A family history does not automatically mean you will develop the disease. Genetic counselling can help families understand whether testing is appropriate.
Atypical presentations: Some people first have prominent problems with language, visual processing, planning or behaviour rather than memory. For example, Alzheimer’s can underlie a language-led condition called logopenic primary progressive aphasia or a visual-processing condition called posterior cortical atrophy. These symptom patterns can have other causes and need specialist assessment.
The terms mild, moderate and severe describe stages of symptoms and support needs, not separate types of Alzheimer’s.
Getting the right assessment
A clinician may ask about changes over time, review medicines, assess thinking and daily functioning, and arrange tests or scans when appropriate. With your permission, input from someone who knows you well can be useful.
Sleep problems, depression, medicine effects and other illnesses can also affect memory. Some are treatable, which is another reason to avoid diagnosing yourself from an online checklist.
There is currently no cure for Alzheimer’s, but treatment and practical support can help manage symptoms and daily life. A specialist can explain which options are appropriate and available locally. Earlier assessment also gives people more opportunity to discuss their wishes and plan support while remaining involved in decisions.
A sudden change is different: confusion that develops abruptly, or a rapid deterioration in someone already living with dementia, needs urgent medical assessment. Do not assume it is simply the next stage of Alzheimer’s.
A diagnosis changes the support a person may need. It does not erase their identity, relationships or right to be heard.
