Hallucinations in seniors can be a serious problem for caregivers. Hallucinations are a symptom of many health problems which disproportionately affect seniors. Alzheimer’s Disease, Fronto-Temporal Dementia, and Parkinson’s Disease can all cause hallucinations.

Hallucinations are sensory experiences that feel completely real but are produced by the mind. Hallucinations can be visual (“seeing things”), auditory (“hearing voices”), or even tactile (feeling a bug on our skin) the form of visual experiences (seeing things), auditory experiences (hearing voices), or even tactile experiences (feeling bugs on the skin).

Hallucinations do not have to be terrifying experiences. There are times when failing eyesight can cause an elderly person to see things that the person knows are not real. This is called Charles Bonnet Syndrome. These hallucinations due to visual changes are not usually distressing for the sufferer.

However, many people with hallucinations will also suffer from delusions. A delusion is a false belief that cannot be proven wrong. When someone is having a delusion, there are no facts or evidence that can change their mind. In fact, a person with a delusion will typically become angry, suspicious, or paranoid when the belief is questioned. Many hallucinations will be accompanied by the delusion that the hallucinated experience is 100% real.

Common causes of hallucination in the elderly

Anyone having hallucinations should be evaluated by a doctor to determine the cause and provide treatment. Some hallucinations might be due to problems like delirium which is a medical emergency and requires immediate attention. This is why it is vital to reach out to the doctor treating your loved one right away.

So far we have listed the following causes of hallucinations in elderly people:

  • Alzheimer’s Disease
  • Fronto-Temporal Dementia
  • Parkinson’s Disease
  • Charles Bonnet Syndrome
  • Delirium

Other than these major issues, hallucinations can also be caused by stroke, dehydration, epilepsy, brain tumors or aneurysms, sleep deprivation, hearing or vision loss, drug or alcohol dependency, liver or kidney failure, or medication. 

There are many drugs that may behave differently in older patients with memory problems. Here is a resource from a renowned hospital that lists common drugs which your doctor may want to avoid. We want to stress, however, that no medication should be stopped, changed or started before a conferring with a doctor.

Recognizing hallucinations

In order to successfully deal with hallucinations, caregivers have to notice that there is a problem in the first place. There are some signs that you should look out for if you are caring for an elderly loved one. Some people will come out and tell someone about their hallucination, but not everyone. If you think your loved one might be experiencing some type of hallucination but isn’t telling you about it, there might be some clues.

Before we list these clues, there is one over-arching idea that you can employ. The idea is this: distraction. If someone appears distracted by something–and nothing distracting is happening–then there is a possibility that they may be bothered by something other people cannot see, hear, smell or touch. Sometimes there is another explanation, but a person should not appear distracted in a quiet, empty room.

Other clues that someone is hallucinating include anxiety, confusion and delusions, speech difficulties, heightened sense of awareness, drastic changes in mood or behavior, withdrawal from friends and family, reduced sense of judgment, insomnia, and mentioning individuals or things that are not there. 

If you happen to notice these symptoms, then it is important to reach out to a doctor right away. If the person was behaving normally not long before you notice them hallucinating, then you need to go to the Emergency Room. Sudden changes in someone’s mental status could be a sign of a stroke or delirium from a serious and time-sensitive illness. Time is brain.

Dementia is a leading cause for hallucinations in elderly

A doctor may determine that someone’s hallucinations are due to dementia. Dementia changes the brain and can lead to seeing, hearing or even feeling, tasting and smelling things that are not there. Dementia distorts the brain and so it can cause seniors to misinterpret their senses. 

When this happens, it is important for caregivers to remember that no matter how fake you believe the visions or voices are, they are very real to the senior. Nothing you say will convince them otherwise. So, make sure that you validate your loved one’s feelings first. You should respond to their complaints as kindly as possible and try to keep their physicial saftey in mind. 

These visions can be especially common in patients with Lewy Body and Parkinson’s dementia. Fortunately, they are not always scary. Sometimes hallucinations will simply include ordinary people, objects or situations. They can even be happy or pleasant. 

Tips for caring for a senior with hallucinations

Once a doctor has determined that your loved one is safe to care for at home, you may have to provide care while that person suffers from intermittent or persistent hallucinations and delusions. If you are caring for someone who is experiencing hallucinations, there are a couple of things you can do when responding. 

Think about whether or not you need to respond at all 

At times, for example when the senior is having pleasant or happy hallucinations, it may be fine to simply leave them alone so as to not call attention to it. In cases like this, it may be easier and safer to simply accept that hallucinations are a symptom of dementia or aging and leave it be unless they become scary or harmful. However, if the hallucinations are upsetting or making your senior feel unsafe, then it is important to respond with one of the strategies below. 

Remain calm and do not attempt to convince them that they are wrong

When your elderly loved one tells you that they are seeing/feeling something, they are saying so earnestly and that hallucination is very real to them. So, make sure that you do not unnerve or contradict them. Contradicting them or arguing will not work and can instead, make the senior feel unsafe because they will realize that you do not believe them. 

Instead, approach them calmly and if possible, ask them to tell you exactly what they are hallucinating. If you listen carefully and make out what they are seeing or hearing, you can get a better sense of whether or not the hallucinations are an emergency or not. 

Tell them you trust that they are not lying

Along with avoiding contradictions or arguments, be careful when you talk to the senior about their experience. Do not dismiss their hallucinations or tell them that they are being silly. Instead, it may be helpful to let them speak with you about what they are experiencing. If you take your senior seriously and validate their concerns, then you will create a more secure environment for them. 

Instead of focusing on the senior’s hallucination, maybe you can respond to how they are feeling about it instead. If your loved one is scared, try to make them feel safe. If they are happy, then try to be happy with them. Tell them you understand why they feel scared or worried. Be supportive and ask them how you can help, if they come to you for assistance. 

Make your elderly loved one’s environment feel safer 

There are certain objects or aspects of the senior’s environment that can make them have hallucinations. These can include background noises or too much visual stimulation. Removing these types of triggers can help the senior feel safer instantly! You could try turning off the TV or radio, opening the blinds, removing any mirrors that could be causing fear or confusion. 

Reassure the senior and simplify their situation 

When seniors have hallucinations, they can get very confused and disoriented. This means that trying to explain to them what is happening in a complex way will only make the situation worse. Instead, simplify the way that you speak. Tell the senior not to worry, reassure them that you will protect them and keep them safe. Physical comfort can also be helpful. Hugging your loved one or gently patting their arm or shoulder can reassure them greatly. If your loved one feels that they can speak to you about this issue, it will be a good distraction. 

Determine if there is a pattern 

If you cannot figure out what is triggering your senior’s hallucinations – especially when they are frequent, it may be best to track their behavior and try to determine a pattern. For example, you can keep notes on the person’s routine and see when hallucinations happen throughout the day. Maybe it’s happening after certain meals or physical activity. Maybe they have made some minor change in their routine and it’s disorienting. Either way, keeping notes can help find you a solution. 

Redirect the senior’s attention 

You can also distract your loved one from their hallucination. This can be an effective technique in dealing with the issue. Instead of concentrating on the hallucination or making them talk about it, you can refocus them on another activity. Whether it is watching their favorite movie, reading a book they like, going through old photo albums, eating their favorite meals or taking a walk outside, all that matters is that the senior enjoys it. 

Ask for support 

Caring for someone with a terminal illness or someone who is advanced in age is not easy in general. So, if we add hallucinations to the burden, it can become overwhelming. This is where having a support system can be extremely helpful, convincing you that you are not alone. Caregiver support groups may be a great option for finding assistance. These groups can be online or in-person and they can provide you with a lot of helpful tips and solidarity. 

Reach out to a medical professional 

If you do not understand why the hallucinations are happening or are afraid that there may be an underlying cause to them that has still not been diagnosed, then it is a good idea to speak with your elderly loved one’s doctor. A medical professional will give you guidance on how to respond and can help you formulate the best strategy for reducing and eliminating hallucinations. 

It is especially important to contact your doctor if you believe that the hallucinations are being caused by a new medication your senior is taking. The doctor will want to monitor the side effect or modify the prescription. In addition, if the hallucination is putting the senior in danger, forcing them to behave in a way that may be physically or emotionally harmful for them, the physician may want to introduce approaches that include drug treatment. 


Overall, we hope that this article has helped you understand hallucinations and prepared you for dealing with them if the need arises.
