WHAT ARE THE FIRST STEPS IF YOU SUSPECT ALZHEIMER'S?

Noticing changes in memory or thinking can feel worrying, especially when Alzheimer’s disease is one of the possibilities people immediately think about. Many people are unsure whether symptoms are part of normal ageing, stress, or something more serious.

The first step is not to panic, but also not to ignore persistent changes. Memory problems can have many different causes, and Alzheimer’s disease is only one possibility. However, if symptoms are becoming more noticeable or starting to affect everyday life, it is important to seek medical advice sooner rather than later.

Early assessment can help identify treatable causes, provide reassurance where appropriate, or allow earlier support if dementia is present.

If you are concerned about your memory or someone else’s, arranging a GP appointment is usually the best place to start.

Many people delay speaking to a doctor because they feel nervous about what symptoms could mean. Others may dismiss problems as normal ageing. However, getting assessed early can make a significant difference.

A GP can review symptoms, look at medical history, arrange initial tests, and help determine whether further investigation is needed. In many cases, memory problems turn out to be linked to stress, anxiety, depression, medication side effects, or other medical conditions rather than Alzheimer’s disease itself.

Even when dementia is present, earlier assessment may allow people to access support, plan ahead, and begin treatment sooner where appropriate.

Alzheimer’s symptoms usually develop gradually over time rather than appearing suddenly. Because changes can happen slowly, they are sometimes first noticed by family members or close friends rather than the individual themselves.

One of the most common early signs is short term memory loss that begins affecting daily life. This may include forgetting recent conversations, repeatedly asking the same questions, or struggling to remember appointments and recent events.

Other early symptoms may include:

• Misplacing items more often

• Difficulty finding the right words

• Problems planning or managing tasks

• Getting confused in familiar places

• Difficulty following conversations

• Changes in mood or personality

• Becoming more anxious, withdrawn, or irritable

It is important to remember that occasional forgetfulness is common and does not automatically mean dementia. For example, forgetting a name briefly and remembering it later is often considered a normal part of ageing.

The main concern is when memory or thinking problems begin disrupting daily activities or gradually worsening over time.

Before seeing a doctor, it can help to keep a simple record of symptoms.

This does not need to be complicated. Writing down what changes are happening, when they started, how often they occur, and whether they are worsening can make appointments more useful and focused.

For example, someone may notice they are repeatedly forgetting conversations, becoming confused while driving familiar routes, or struggling to manage finances or household tasks.

Tracking symptoms can also help identify possible patterns. In some cases, memory issues may worsen during periods of stress, poor sleep, or anxiety, which can sometimes point towards causes other than dementia.

Family members or close friends may also notice changes first. Some memory assessment tools even include questions for partners or relatives because outside observations can provide important information.

Alzheimer’s Society also provides dementia symptom checklists that can help people organise concerns before speaking to a GP. These checklists are not diagnostic tools, but they may help guide conversations during appointments.

A GP is usually the first healthcare professional involved in assessing memory concerns.

During the appointment, the GP may ask questions about:

• Memory changes

• Mood and mental health

• Sleep

• Stress levels

• Daily functioning

• Medical history

• Current medications

They may also ask whether symptoms are affecting work, driving, finances, cooking, or other everyday tasks.

Simple cognitive or memory tests are often carried out during these appointments. These assessments help doctors understand whether memory difficulties may require further investigation.

Blood tests may also be arranged to check for other possible causes of memory symptoms, such as vitamin deficiencies or thyroid problems.

If concerns remain after the initial assessment, the GP may refer the person to a memory clinic or specialist service for more detailed evaluation.

One of the most important things to remember is that memory problems are not always caused by Alzheimer’s disease.

Several physical and mental health conditions can affect memory, concentration, and thinking ability. In younger adults especially, stress, anxiety, and depression are among the most common causes of memory complaints.

Other possible causes can include:

• Vitamin B12 deficiency

• Thyroid problems

• Diabetes

• Liver or kidney disease

• Medication side effects

• Sleep problems

• Infection

Infections can sometimes cause sudden confusion, particularly in older adults. This is known as delirium and may sometimes be mistaken for dementia. However, delirium often develops more suddenly than Alzheimer’s disease, which usually progresses gradually over time.

This is why medical assessment is important before assuming memory problems are caused by dementia.

If initial screening suggests that further assessment is needed, the GP may refer the person to a specialist memory clinic.

At this stage, more detailed cognitive assessments may be carried out to evaluate memory, language, concentration, and reasoning skills in greater depth.

Additional blood tests may also be reviewed to rule out other medical causes of symptoms.

In some cases, brain scans such as MRI or CT scans may be used to look for patterns associated with dementia or rule out other conditions such as stroke or brain tumours.

Occasionally, more specialised tests such as lumbar puncture testing may also be considered.

Importantly, dementia diagnosis is usually based on several assessments together rather than one single test. Doctors look at the overall picture, including symptoms, cognitive testing, scans, medical history, and daily functioning.

Starting a conversation about memory problems with a loved one can feel difficult and emotional.

Many people are frightened by the possibility of dementia and may become defensive or upset if concerns are raised too abruptly. For this reason, it often helps to choose a calm and supportive moment for the conversation.

Rather than making assumptions or saying “I think you have Alzheimer’s,” it is usually better to focus on specific examples you have noticed. For example, you might gently mention repeated confusion, getting lost, or forgetting recent conversations.

Approaching the discussion with empathy and support is important. Offering practical help, such as attending GP appointments together or helping keep notes about symptoms, can also make the process feel less overwhelming.

Earlier assessment and diagnosis can bring several important benefits.

For some people, testing may reveal a treatable medical condition rather than dementia. For others, earlier diagnosis may provide access to support, treatment, and specialist services sooner.

Early diagnosis can also help people and families plan ahead. This may include discussing finances, future healthcare decisions, living arrangements, and legal planning such as powers of attorney.

Treatment and support introduced earlier may also help some people maintain independence and quality of life for longer.

Importantly, early support does not just help the individual experiencing symptoms. It can also provide guidance and reassurance for family members and carers who may be trying to understand what is happening.

Alzheimer’s disease usually develops gradually over time.

If symptoms appear suddenly or worsen very quickly, urgent medical assessment may be needed because another medical problem could be responsible.

You should seek urgent medical advice if someone develops:

• Sudden confusion

• Rapid behaviour or personality changes

• Hallucinations

• Signs of stroke

• Sudden difficulty speaking

• New mobility problems

• Serious safety concerns

These symptoms may sometimes suggest conditions such as infection, stroke, or delirium, which require prompt treatment.
