Psychological health


Psychological health refers to symptoms which impact a person’s psychological and emotional wellbeing in their own right. The needs which arise from these symptoms may be separate from (and in addition to) needs which arise from the cognitive impairment caused directly by dementia.
For example, a person living with dementia might find conversations harder to take part in owing to the word finding difficulties they are experiencing, and the challenges of keeping up with general conversation in a group setting. Their families, friends and carers might be making adaptations to accommodate additional communication needs. If a person is also experiencing hallucinations, their conversation may also include reference to objects which are not actually present in reality. This adds to their communication difficulties, but from a different root cause than the word finding difficulties caused by the dementia itself.
The impact of psychological symptoms varies widely. For example, in some cases, delusions and hallucinations become a part of everyday routines – whilst in other cases, they can be the cause of significant distress and alarm. Psychological symptoms can fluctuate in both their presence and intensity. People may experience significant periods of time where these symptoms are absent altogether – unlike their underlying symptoms which are constant and progressive in nature.
Anticipating and predicting needs that arise out of psychological symptoms can be harder than anticipating and predicting other needs. They can be triggered without warning and can escalate quickly. Many of the initial adaptation strategies focus on validating a person’s experience, entering into it (as opposed to challenging it and seeking to rationalise it) and seeking ways to provide reassurance and calming influences.
Be mindful that people living with rare forms of dementia may experience unusual sensory sensations, such as ‘creeping’ or ‘tingling’. These can be difficult to describe and difficult to dissociate from what is physically ‘real’. They can add to the experience of misperception, hallucination and delusion.
A hallucination is the experience of something that is not really there and can involve any or all of the senses. The most common type of hallucinations are visual hallucinations, when people see things that are not present.
A milder form is an illusion, which is where an everyday object is seen as something else. For example, a jacket hanging on a door is seen as a person, or a hanging basket perceived as a hat. These may sometimes be referred to as misperceptions.
Although hallucinations are imaginary, they seem very real to the person experiencing them. They can cause anxiety, distress, fear, confusion and sometimes panic for the person who is experiencing them, as well as the people around them. However, hallucinations do not always cause distress as sometimes people describe their hallucinations as comforting and welcome.
Hallucinations are frequently experienced in people living with Lewy body dementia (LBD) but may also be experienced by people living with other forms of dementia.
For people living with a diagnosis of dementia, hallucinations are usually caused by changes within the brain. There is still a lot we don’t know about the changes in the brain that lead to hallucinations. They may be a result of more than one change. There are various explanations for why hallucinations happen.
Hallucinations can sometimes be triggered by other changes such as infection, physical illness or as a side effect of some medications.
People who experience hallucinations can describe them affecting different senses. These can include:
“He calls me in to look at the spiders crawling up the wall in the room where he is sitting. I can’t see any spiders at all but cannot convince him that they are not there. He doesn’t mind that they are there and isn’t bothered by them”.
“I sometimes get quite worked up by the sound of children playing in the street outside. The noise can get really loud and I find it very disturbing. My husband tells me that there are no children to be seen or heard, but it doesn’t make any difference to the noise I am hearing.”
“My husband had PCA and regularly described rabbits playing in the front room, just in front of where he was sitting. He wasn’t bothered by them in the slightest!”
“He described seeing hundreds of rats carrying swords and marching along the curtain rails.”.
“I used to set the table for the children that my husband were convinced were joining us for tea. He could describe what they looked like in great detail. Setting the places was enough to keep him assured and calm and I was happy to do this in order to maintain a peaceful environment. ”
When hallucinations are being experienced as a symptom of dementia, it is good to talk with a specialist clinician, as there are practical things that can be done. For example, they will check for causes such as infection or constipation that can trigger hallucinations. They will also review the medications, as there are some treatments that can trigger or worsen hallucinations, such as pain killers and also some of the medications used to treat Parkinson’s such as levodopa. If the hallucinations are bothersome, they might suggest starting a medication to boost the chemicals in the brain called acetylcholine. These medications are called Rivastigmine or Donepezil.
Sometimes stronger medications are needed and these include a group of medications called antipsychotics. Doctors may recommend quetiapine, or sometimes clozapine as treatment in this situation.
The primary goal of supporting a person who is experiencing a hallucination is to keep them safe, to find ways to connect with them, and to de-escalate any distress that is being experienced.
Remember that hallucinations seem very real in the moment. It doesn’t usually work to say that something isn’t there. There are several strategies that might ease the situation. Some may work well at times, and others may be less helpful. But having a number of different things to try, means we can do our best to work out what is most helpful for everyone involved. Before engaging in the various strategies described below, and only if appropriate, it may be worth sensitively bringing someone who is currently trusted into the room to see if they can help diffuse the situation. Suggest closing the eyes and opening them again to see if what they are seeing is still there. If appropriate, have a written reminder message on a whiteboard or piece of paper which says that what is happening is not real and a reminder that it is a symptom of the dementia– a trick the eyes are playing on the brain. Be sensitive in the degree to which these approaches are used and avoid them if they increase distress or confusion.
There are some ways that we can adapt our environments to minimise the likelihood of hallucinations:
Hallucinations can be distressing for the people who experience them as well as for their families, friends and carers, and may leave them feeling anxious, unsafe, depressed, frustrated and angry. Hallucinations can leave a lasting feeling of being ‘unsettled’ in a person living with dementia even if they cannot remember them. For both the person with the diagnosis, and their family, friends and carers, the opportunity to speak about the symptoms of dementia can be helpful. Understanding more about the causes of these behaviours can help in trying to find the best way to live alongside them.
Other factors
It’s also important to make sure that vision and hearing are as good as possible. This is because poor vision and reduced hearing will make hallucinations more likely to happen.
Make sure that glasses and hearing aids are to the correct prescription and fit well. If there are cataracts, consider a referral for these to be treated, as this can make an important difference to a person’s vision and can even reduce hallucinations.
Encourage regular health checks and medication reviews. Regular dental check-ups will identify signs of decay or disease which might be causing altered sense of taste. If appropriate, remove the source of unusual smells around the home and try to identify any changes to washing powder or toiletries that might be causing itching or discomfort.
Dehydration, constipation, underlying pain or medical conditions can all contribute to an increase in the experience of hallucinations. Some medications, for example those that impact dopamine levels, are known to increase the likelihood of hallucinations. In some cases, cholinesterase inhibitors have some modest effect in reducing hallucinations.
Delusions are strongly held ideas that are not based on reality or facts, but are thought to be true by the individual. They are false beliefs. They may sometimes be linked to the experience of a hallucination or an illusion, but they can also exist independently of these.
Delusions are relatively common in people living with dementia. They are most prevalent in Lewy body dementia (LBD) and Alzheimer’s disease, less so in behavioural variant frontotemporal dementia (FTD) and posterior cortical atrophy (PCA) and relatively rare in primary progressive aphasia (PPA).
There are two main types of delusions:
For more information on Capgras Syndrome please see the Lewy Body Society website and this YouTube video.
Other examples can include occasions where people living with dementia wrongly identify other people or themselves. Sometimes a person does not recognise their partner, or may become frightened by their own reflection, thinking it is another person. Voices on the radio or the television may be thought to be from people physically present in the room. Having beliefs such as a need to get to school, work, or back home in time for the family arriving for a meal, also fall within this type of delusion.
Delusions have a range of causes.
“I walked into our family kitchen at breakfast time and my mum asked me who I was. I replied by saying that I was her daughter and that I lived here too!’ to which she replied ‘You are not my daughter. You don’t live here”.
“Dad took me to one side and explained in a very hushed and secretive voice that he knew my brother had been stealing from him. He was convinced that his wallet had been taken and was certain that it was my brother who was the culprit.”
There are countless examples of delusions, which vary from person to person, and over time. Some delusions occur more generally across people living with dementia, whilst others are unique to the personal circumstances of the person experiencing the delusion. Some of the more common types of delusion, and behaviours associated with them can include:
Remember that delusions seem very real in the moment. It doesn’t usually work to say that something isn’t true. There are several strategies that might ease the situation. Some may work well at some times, and others may be less helpful. But having a number of different things to try, means we can do our best to work out what is most helpful for everyone involved.

Be sensitive in the degree to which this approach is used and avoid it if it increases distress or confusion.
Anxiety is a feeling of unease, such as worry or fear, that can range in severity from mild to severe. Everyone has feelings of anxiety at times in their life, and embracing a diagnosis of dementia may trigger feelings of anxiety not just for the person with the diagnosis but also their family, friends and carers.
Anxiety is relatively common in people living with dementia, particularly when there is insight and awareness about what the diagnosis may mean. We often experience anxiety when we are fearful, confused or unable to make ourselves understood. These are relatively typical experiences for most people living with dementia, and often for their family, friends and carers too.
Feelings of anxiety may be accompanied by other psychological symptoms such as a reduced ability to concentrate, irritability and feeling more tired than usual. Physical symptoms of anxiety might include the feeling of a racing heart, feeling nauseous or having an upset tummy, or feeling dizzy and short of breath. There may also be some changes in behaviour, such as restlessness or fiddling, a tendency to hoard things, and a need for more reassurance than usual.
People living with dementia sometimes struggle to communicate their anxiety, either because they are trying not to show it, wanting to protect the people around them from seeing it, because it is difficult to identify, or because of difficulties communicating what is being felt. The physical and behavioural symptoms of anxiety can be a helpful prompt to open up conversations and discussions about reasons for possible underlying anxiety.
The information on this page is not a replacement for professional assessment and diagnosis of anxiety, but is intended to provide some helpful tips for people who are feeling some of the symptoms of anxiety because of a diagnosis of dementia. It is important to seek professional advice if feelings of anxiety are having a significant impact on quality of life and daily living activities.
“I don’t want my family to feel burdened by me as this diagnosis develops. I am fearful for them and their wellbeing.”
“He often describes being frightened at the thought of the symptoms he may develop. Sometimes the fear of what might happen in the future really makes it difficult for us to make the most of today and enjoy whatever moments we can.”
“We have a collective sense of frustration as a family– we feel cheated out of the future we were expecting, and I find myself feeling very worried about what it will look like now.”
“I find myself getting very anxious about how the symptoms will progress. I can’t bear the thought of him losing some of those skills and abilities I know mean so much to him. It’s as much about the small things as the big things. Cutting the grass, cooking a meal, generally helping around the house– it feels as if everything is at risk of being lost. It can feel utterly overwhelming and disabling at times.”
“Mum can’t articulate exactly what her day to day anxieties are, but she is definitely more on edge and nervous than she ever was before she got the diagnosis. She used to be very laid back.”
“They used to be able to enjoy activities independently of each other as well as having several shared ones too. Since her diagnosis, mum won’t let dad out of her sight. She wants to be by his side the whole time and gets very agitated if he isn’t in the same room, let alone the house. It must be hard for mum, but we also worry about the impact on dad.”
Some examples of the anxieties that people describe as they embrace a diagnosis of dementia include or relate to:

For people living with dementia, their family, friends and carers, the opportunity to speak about their worries and anxieties is especially important.
Depression can coexist alongside a diagnosis of dementia. It is relatively common in people living with dementia, but can be missed, as some of the symptoms are similar to symptoms of dementia. As is the case for everyone, people living with dementia can experience depression in a variety of ways, and at any stage of their illness. It is often diagnosed when a person is in the earlier stages of dementia but can occur at any time.
Depression is more than feeling sad or unhappy for a few days. It affects people in different ways and can cause a wide variety of symptoms. They range from:
Depression can also cause symptoms of anxiety including:
Physical symptoms are also common, such as:
Some people become depressed as a reaction to negative events or from not having positive experiences to look forward to. Dementia can be a distressing experience, the diagnosis and implications of which can cause depression, as people think about the negative effect it might have upon their life and the way it may reduce opportunities for positive experiences to look forward to.
Dementia also changes the way the brain functions. It can damage the parts of the brain involved in mood and can affect a persons emotional state which in turn makes the experience of depression more likely.
Other factors that are known to trigger depression include:
All these factors can be present for people living with dementia, as well as for their family, friends and carers too.
It can sometimes be difficult to differentiate depression from the natural responses to loss that a diagnosis of dementia can cause, and the reactions and grief we feel in response to those losses. A diagnosis of dementia is life changing and it is normal for people to react with sadness and grief for the losses that it entails. See the RDS website information on loss and grief for further detail.
It is important not to overlook the possibility of depression – especially as there are treatment options available which can significantly improve the quality of life for people living with depression, grief and reactions to loss. It is important to talk about the way we are feeling and be honest about things we are finding hard. Speaking to a family member or friend is sufficient and appropriate for some people. For others, this isn’t possible or appropriate, and some people prefer the anonymity of speaking to a professional or volunteer whose skills and role it is listen.
Treatment options often include:
“It became so hard to know where the lines were drawn. We couldn’t be sure whether Dad’s irritability and low mood was a natural reaction to the difficulties his posterior cortical atrophy [PCA] was causing. Having to stop work, not being able to read his papers, and having to stop driving was bound to have a huge impact on anyone. We were thankful for the opportunity of a 6-session counselling programme via RDS, and in fact we continued with a local counsellor privately afterwards, having gained confidence in the type of approaches that best worked for Dad.”
“As well as feeling shaken by the diagnosis, I found I was increasingly unable to settle or focus on anything– even the things I was still able to do, like gardening and going to local gigs– all of which had an increasingly negative effect on how I felt and coped. A low dose antidepressant actually helped my mood as well as easing the agitation and enabled me to have the energy and enthusiasm to find strategies and adapt much more readily. I know it isn’t the answer for everyone, but for me, it helped.”
