Changes in memory, orientation or behaviour can have various causes. This guide helps to distinguish between sudden and gradual developments, recognise everyday risks and organise support in such a way that dignity and independence are maintained as far as possible.
01
Recognising changes and placing them in a timeline
To a certain extent, forgetfulness is part of everyday life. People misplace things, forget a name or need a reminder about an appointment. That in itself does not mean that dementia is present. You should be alert if abilities change significantly, if everyday tasks can no longer be carried out reliably, or if confusion suddenly sets in.
Occasional forgetfulness
A piece of information comes back to mind later or can be recalled with a prompt. Familiar activities and important decisions can still be carried out largely independently. Occasional moments of forgetfulness may also be linked to stress, poor sleep, pain or strain.
Gradual changes
Over weeks or months, managing appointments, medication, financial matters, familiar routes or routine tasks becomes increasingly difficult. Such developments should be closely monitored and assessed by a doctor. They do not automatically mean that dementia is present.
Sudden confusion
If confusion develops within a short period of time or fluctuates significantly throughout the day, there may be an acute physical cause behind it, such as an illness, a medication or dehydration. This should be assessed by a doctor as soon as possible and should not be hastily dismissed as a normal progression of dementia.
Notable changes may include, for example:
repeatedly forgetting important appointments or arrangements
frequently misplacing items in unusual places
difficulty managing medication, money or household appliances
problems finding familiar routes
uncertainty when carrying out familiar tasks such as cooking, shopping or making phone calls
Frequently repeating the same questions or stories
Noticeable difficulty finding the right words
Changes in mood, drive or behaviour
Increasing withdrawal from conversations or activities
Suspicion, restlessness or severe anxiety without any apparent cause
Such observations do not automatically mean that dementia is present. Problems with memory and orientation can have various physical, psychological or medication-related causes. A medical assessment helps to ensure that treatable triggers are not overlooked and to better assess the need for support.
It is helpful for relatives to document changes as specifically as possible: What have you noticed? Since when? How often? In what situations? Did something change suddenly or develop gradually? Were there any new medicines, a hospital stay, an infection or other stressors?
Not every instance of forgetfulness is dementia. The key factors are the nature of the change, its progression and the impact on daily life – sudden confusion requires particular attention.
02
Recognise everyday risks and respond appropriately
When memory, orientation or attention start to decline, familiar routines can become uncertain. The risk arises not solely from the diagnosis, but from the specific situation: Is the person taking the wrong medication? Can they not find their way home? Are they no longer able to recognise a hazard in the home? Support should therefore be tailored to the person’s actual abilities and risks.
Forgetting to take medication
Medication is sometimes missed, taken twice or taken at the wrong time of day. This is particularly risky when several medicines are involved or when the medication schedule changes frequently. Fixed taking times, pill boxes, reminders and clear documentation can be helpful. If the person can no longer reliably take their medication independently, support should be organised.
Mixing up appointments
Doctor’s appointments, visits from the care service, therapy sessions or family arrangements can be mixed up or forgotten. A clear calendar, regular routines and timely reminders can help. It is important not just to jot down appointments anywhere, but to do so in a way that is clearly visible and understandable to both the person affected and their supporting relatives.
Restlessness
Restlessness can manifest as pacing, constantly getting up, searching for things, fidgeting, asking the same questions repeatedly or feeling tense. There are often triggers: pain, the need to urinate, hunger, thirst, feeling overwhelmed, loneliness, unfamiliar surroundings or too many stimuli. Relatives should observe when restlessness occurs and what makes it worse or helps to calm it down. This helps to better adapt daily routines.
Leaving the home and losing one’s bearings
Some people leave their home and cannot find their way back safely. This may stem from a search for a familiar place, a person, a past activity, or simply the need for movement. A personalised safety plan, informed carers, up-to-date contact details and supervised opportunities for exercise can be helpful. Tracking or monitoring solutions must be assessed with regard to consent, proportionality and legal requirements.
Mistrust
Mistrust can arise when the person affected is no longer able to make sense of situations. Misplaced items may then be perceived as stolen, strangers as threatening, or well-meaning help as interference. This is emotionally difficult for relatives. It is usually helpful not to contradict or argue straight away, but to remain calm, reassure the person and try to identify the underlying concern.
Altered day-night rhythm
In cases of dementia and other cognitive impairments, the sleep-wake cycle can become disrupted. Some people are awake at night, wandering about or restless, whilst they are tired during the day. This also places a heavy burden on family members. A fixed daily routine, plenty of daylight, exercise, regular meals and a calm evening routine can help. If night-time restlessness is severe or occurs suddenly, a doctor should be consulted to check whether pain, infections, medication or other causes are involved.
Repetitive questions
Repeated questions are a common and exhausting part of everyday life. The person affected does not ask the same thing over and over again on purpose, but because they cannot reliably store or recall the answer. Short, calm answers, visual cues, notes, calendars or set routines can help. Relatives should also take their own stress seriously, as constantly repeating things takes a toll.
Not every situation can be resolved immediately. It is helpful to ask about triggers, recurring patterns and the specific risks involved. If a task that was previously managed independently can no longer be carried out safely on a repeated basis, the support provided should be adjusted. This could involve a reminder, a simplified environment, taking over individual steps or seeking professional help.
03
Providing structure and maintaining abilities
In cases of dementia and increasing forgetfulness, a clear structure can make everyday life significantly easier. It does not take away the person’s independence, but rather provides a sense of direction. The more familiar and predictable routines are, the less there is a need to constantly make new decisions, remember things or explain them.
Fixed routines
A regular daily routine provides a sense of security. If getting up, mealtimes, taking medication, personal hygiene, exercise and rest periods follow a pattern that is as consistent as possible, it helps the person affected to find their bearings. Fixed times and recognisable sequences are particularly helpful: breakfast first, then medication; a walk after lunch; and always the same calm routine in the evening before going to bed.
Routines also take the strain off carers. They do not have to plan and explain things from scratch every day, but can follow a familiar routine. At the same time, it becomes apparent more quickly if something is not going as usual.
Visible cues
Signs and reminders around the home can help, without the need for constant questioning or reminders. These include easy-to-read calendars, clocks, labels, sticky notes, pictures or simple symbols. A visible daily schedule can also be helpful: what’s happening today? Who’s coming round? When is dinner? When is an appointment due?
It is important to keep cues simple and unambiguous. Too many notes, text that is too small or conflicting information can be more likely to cause confusion. It is better to have a few clear points of reference in fixed locations.
Clear procedures
The more complicated a routine is, the more likely it is to cause uncertainty and overwhelm. That is why tasks should, where possible, be broken down into simple steps. Instead of giving several instructions at once, it is often more helpful to guide the person through one step at a time.
This applies, for example, to personal hygiene, getting dressed, mealtimes, taking medication or leaving the home. Clear routines help the person concerned to participate without constantly being corrected. They promote independence where it is still possible and provide support where it is needed.
Familiar objects
Familiar objects can provide a sense of orientation and security. These might include photographs, furniture, clothing, a particular cup, a favourite armchair, familiar music or personal mementoes. They help the person recognise their surroundings and feel more at ease.
It is therefore important to proceed with caution, particularly when making changes. Making a home more ‘practical’ can be sensible, but too many changes at once can be unsettling. It is often better to combine safety with familiarity: remove trip hazards and keep pathways clear, whilst retaining important personal belongings and familiar landmarks.
A good structure makes everyday life more predictable without making it unnecessarily rigid. It supports existing abilities and only provides additional support where help is needed.
04
Maintaining connection and communicating respectfully
When memory and orientation start to decline, communication changes too. Conversations can become more difficult because information is no longer retained reliably, contexts are understood differently or situations are misinterpreted. This is often exhausting for carers. At the same time, adapting the way we communicate can go a long way towards avoiding stress, arguments and uncertainty.
Behaviour that initially seems incomprehensible may express a need or a source of distress: pain, anxiety, feeling overwhelmed, hunger, thirst, the need to urinate, tiredness or a need for reassurance. Before simply correcting the behaviour, it is therefore worth asking what the person is currently perceiving or needing.
Don’t correct behaviour at any cost
If a statement is obviously incorrect, it is natural to contradict it immediately. However, this is not always helpful. People who are no longer able to orientate themselves with confidence sometimes experience a correction as humiliation, criticism or an attack. Particularly in the case of repeated questions, false memories or mix-ups, it is therefore important to weigh up the situation: does this really need to be corrected right now, or is the priority at this moment to provide reassurance and calm?
This does not mean confirming every incorrect statement. It means responding sensitively. Instead of saying, ‘That’s not true, I’ve already told you that,’ it can be more helpful to reply calmly: ‘I’ll sort that out’ or ‘Let’s have a look at it together in a moment.’ The key is not to make the situation unnecessarily worse.
Short sentences
Long explanations can be overwhelming. Short, clear sentences, giving one piece of information at a time, are better. Questions should also be kept as simple as possible. Instead of offering several options at once, it can help to narrow down the choice: “Would you like tea or water?” is often easier than an open-ended question about all possible drinks.
The same applies to instructions: take it step by step. Don’t say: “Please get dressed, take your tablets and then we’ll set off straight away.” Instead, start with: “We’re going to put on your jacket now.” Then move on to the next step. This keeps the situation clearer.
A calm atmosphere
People with dementia often react sensitively to hustle and bustle, loud noises, time pressure or multiple stimuli at once. A calm environment can make conversations much easier. This includes speaking as slowly as possible, making eye contact, minimising distractions and allowing enough time for responses.
Your own attitude also plays a part. If carers are tense, impatient or annoyed, this can easily rub off on the situation. This is only human and not always avoidable. Nevertheless, it helps to pause briefly before difficult conversations and make a conscious effort to start calmly. Sometimes it is the tone, rather than the content, that determines whether a situation goes well.
Maintaining dignity
Even if someone is forgetful, uncertain or confused, they remain an adult with their own life story, their own preferences and a right to respect. Communication should therefore not be patronising, disparaging or childish. It is important to involve the person, to make decisions together wherever possible, and not to speak over their head.
Dignity also means not highlighting mistakes. If someone gets something wrong, repeats a question or does not understand a situation, the response should be as supportive as possible. The aim is not to be right, but to provide guidance, reassurance and trust.
The aim of good communication is not to correct every statement. What matters most is mutual understanding, guidance, reassurance and respectful interaction.
Dementia and increasing forgetfulness can place a heavy strain on relatives. Repeated questions, restlessness at night, accompanying the person outside the home, or responsibility for medication and safety cannot be managed in the long term through attention and perseverance alone. If care depends on a single person, their exhaustion simultaneously becomes a risk to the stability of the entire daily care routine.
An important way to ease the burden is to view behaviour not merely as isolated difficult situations, but to recognise patterns. Simple record-keeping can help with this. You should not note down everything, but rather focus on what stands out: When does restlessness occur? In which situations does the person become suspicious? When do they ask the same questions particularly frequently? Are there nights with little sleep? Does uncertainty arise following certain appointments, visits or changes?
Brief, specific observations are helpful:
What happened?
When did it happen?
How long did it last?
What led up to the situation?
What calmed things down or helped?
What tended to make the situation worse?
This makes it easier to identify possible triggers. Restlessness, for example, may be linked to pain, the need to urinate, hunger, thirst, tiredness, feeling overwhelmed, loneliness or too many stimuli. Distrust can arise if objects have been misplaced or a situation is no longer understood. Repetitive questions sometimes occur particularly when an appointment is coming up or the person feels uncertain.
Once such connections become apparent, carers can respond in a more targeted way. Perhaps a calmer daily routine, a different time of day for personal care, more exercise in the afternoon, a clearly visible daily schedule or fewer stimuli in the evening might help. Not every measure works immediately, but without observation, much of it remains a matter of guesswork.
It is also important to organise help at an early stage. Relatives should not wait until the burden becomes almost unbearable. Care advice services, GPs, specialists, home care services, day care, support services or support groups for relatives can provide assistance at an early stage. This is particularly true if night-time restlessness, wandering off, falls, aggression, severe exhaustion or increasing uncertainty in everyday life occur.
Seeking relief is not a shirking of responsibility. It distributes care, knowledge and availability in such a way that care remains sustainable in the long term.
