Who Does It Affect
Changes in perception and less commonly, hallucinations, can affect anyone who has physical changes to either their sensory organs, or their brain or both. This means that it can affect people who have sight or hearing problems, delirium, an infection, side effects or adverse effects from taking medication, or the over-use of alcohol.
Changes in perception are more common in people with dementia as they may experience these physical changes to their sensory organs, as well as experiencing changes in the brain. People who are diagnosed with dementia with Lewy bodies are more likely to have visual hallucinations than people with any other form of dementia, due to the particular changes in the brain that take place with this kind of dementia.

Hallucinations And Dementia: Are They Common
It is important to talk about hallucinations and dementia seeing that this is one of the most common symptoms that persons with this neurodegenerative disease experience.
Hallucinations are incorrect perceptions about experiences or things that involve the senses that can result in a negative or positive experience.
The Seven Stages Of Dementia
One of the most difficult things to hear about dementia is that, in most cases, dementia is irreversible and incurable. However, with an early diagnosis and proper care, the progression of some forms of dementia can be managed and slowed down. The cognitive decline that accompanies dementia conditions does not happen all at once – the progression of dementia can be divided into seven distinct, identifiable stages.
Learning about the stages of dementia can help with identifying signs and symptoms early on, as well as assisting sufferers and caretakers in knowing what to expect in further stages. The earlier dementia is diagnosed, the sooner treatment can start.

What You Can Do
First, its important to help your loved one manage the hallucination. Rather than argue, try to change the subject or offer a distraction instead. Call your loved ones physician in the case of frequent hallucinationsrelief may be provided through non-drug therapies such as meditation. Antipsychotic medications can work in the most severe cases, but theres also an increased risk of stroke with these drugs.
While dementia can cause hallucinations, its important to be aware that other senior health concerns can cause them as well. Examples include Parkinsons disease and dehydration.
Caring for a loved one with dementia is a challenging task for anyone. The responsibilities can sometimes feel overwhelming, but help is available. Seniors can face a variety of age-related challenges. Though some families choose to take on the caregiving duties, there may come a time when they need a trusted senior care provider.

Call us today at 573-4213 to discuss how we can give you the peace of mind that comes from knowing your loved one is being cared for with professionalism and compassion.
Responding To Paranoia In Elderly Dementia Patients
Paranoia tends to worsen as a dementia patients cognitive abilities decline. According to the Alzheimers Association, when paranoia occurs, caregivers should assess the problem and devise solutions by considering these questions:
- What happened right before the person became suspicious?
- Has something like this happened before?
- Was it in the same room or at the same time of day?
- Can a trigger be removed or altered to avoid eliciting suspicion?
If someone is exhibiting paranoid behavior, it is important to discuss their medications with their doctor. Sometimes medications interact with one another or the dosages are too large, notes Somers. That can bring on paranoia, but a doctor can address problems and adjust the seniors regimen to minimize issues.

What Are Visual Hallucinations
Hallucinations, defined as the perception of an object or event in the absence of an external stimulus, are experienced by patients with conditions that span several fields . When noted by nonpsychiatrists, visual hallucinations, one type of sensory misperception, often trigger requests for psychiatric consultation, although visual hallucinations are not pathognomonic of a primary psychiatric illness.
Visual hallucinations have numerous etiologies. Here, we discuss possible mechanisms and offer a differential diagnosis of visual hallucinations, with an emphasis placed on conditions that arise in the context of medical and surgical illness. Treatment typically rests on the underlying etiology, so timely recognition and an understanding of causative mechanisms are crucial.
Visual Hallucinations: Differential Diagnosis And Treatment
Have you ever encountered a patient who reported isolated visual hallucinations but did not have any other symptoms of delirium or psychosis? Have you wondered which medical and neurologic illnesses may present with visual hallucinations? Have you deliberated about how best to work up and treat patients with visual hallucinations?
If you have, then the following questions and answers should serve to frame the differential diagnosis of visual hallucinations and to explore the available options for diagnostic testing and treatment.

Approaches For The Caregiver
Caregivers of patients with dementia should be educated about the disease process and the disease manifestations being exhibited. Attendance at support group meetings, personal discussion with the physician, and resources such as The 36-Hour Day7 and the Alzheimers Association may be helpful. In most situations, coping strategies include remaining calm and using touch, music, toys, and familiar personal items. Helping the caregiver understand the lack of intentionality of the behaviors is essential.

Individuals with dementia-related psychosis commonly experience visual hallucinations, auditory hallucinations and distortion of senses, according to data presented at the Alzheimers Association International Conference 2020.
ACADIA is committed to understanding the lived experience of people with dementia-related psychosis, for whom there are no approved treatments,Teresa Brandt, PhD, executive director of regulatory affairs at ACADIA Pharmaceuticals, told Healio Psychiatry. The aim of this study was to capture the lived experience of people with dementia-related psychosis, either directly or via caregiver input, which can be exceedingly difficult in patients with cognitive decline who may no longer be able to act independently and raise their own voice. Although there are numerous publications noting the prevalence of psychotic symptoms across dementias, what was missing was an understanding of the specific impacts that hallucinations and delusions have on people living with dementia.

Is There Any Link Between Dementia And Hallucinations
Dementia can affect the brain activities of people, which can lead to odd and frightening behavior. People with dementia often experience hallucinations due to the changes in brain cells. The changes impact their senses. During a hallucination, a patient may feel or think they are hearing, seeing, or smelling something that is not actually present. It is something that causes the patient to believe something is real when its not. The sights or sounds or odors a patient feel or experience dont exist for a normal person. If you have seen your older parent or someone else experience dementia, you must know how scary and hard it is to deal with it.
Hallucinations often happen during the middle or last stages of dementia. They are more common with certain types of dementia, such as Parkinsons disease, Alzheimers disease, and Lewy Body Dementia.
Hallucinations Illusions And False Memories Can All Occur In Dementia
Not seeing the left side can occur with occipital or parietal lobe damage.
In my last post, I mentioned how the parietal lobes help to focus attention, and that it is asymmetric. Although the right parietal lobe attends to both the left and right sides of the world, the left parietal lobe attends only to the right. For this reason, if there is damage to the right parietal lobe, the ability to pay attention to things on the left is lost, and so things on left may not be observed unless they are explicitly pointed out. Right parietal lobe damage can be from a stroke as part of vascular dementia, although it can also occur from many other types of dementia, including Alzheimers disease. Lastly, occipital lobe damage from stroke or dementia can cause loss of vision on either side.
The temporal lobes tell you what you are looking at and your emotional connection to it.
When an imagea dog, for examplereaches the temporal lobes, you will be able to identify the image as a dog, what color its hair is, and which breed it is. Also in each temporal lobe are the emotional centers of the brain, almond-shaped structures called amygdala. When the image reaches the amygdala, it produces the appropriate emotion: affection if it is your dog and wariness if you have never seen the dog before.
Illusions occur when there are misperceptions.
Hallucinations may be due to problems in the visual systemor a sleep disturbance.

Visual Hallucinations Are More Common
Hallucinations experienced by older adults with dementia can affect all the senses, but theyre more often visual in nature. If other senses are affected, your loved one may taste , feel , hear , or smell things that arent really there. Visual hallucinations related to dementia could involve: Interpreting shadows as scary people or animals Seeing flashing or blinking lights that arent there Experiencing a real situation as something entirely different

Stage : Mild Cognitive Impairment
Clear cognitive problems begin to manifest in stage 3. A few signs of stage 3 dementia include:
- Getting lost easily
- Noticeably poor performance at work
- Forgetting the names of family members and close friends
- Difficulty retaining information read in a book or passage
- Losing or misplacing important objects
- Difficulty concentrating
Patients often start to experience mild to moderate anxiety as these symptoms increasingly interfere with day to day life. Patients who may be in this stage of dementia are encouraged to have a clinical interview with a clinician for proper diagnosis.

When This Happens What Do We Do
If you are a caregiver and your loved one is seeing bugs that you do not see, or accusing you of stealing something, it is human nature to respond with What bugs? or I didnt steal anything. Remember though, that your loved ones behaviors are likely coming from changes in the brain related to the Alzheimers or dementia. Becoming dismissive, defensive or arguing your point will not be effective.
Dementia Is A Leading Cause For Hallucinations In Elderly
A doctor may determine that someones 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 ones 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 Parkinsons dementia. Fortunately, they are not always scary. Sometimes hallucinations will simply include ordinary people, objects or situations. They can even be happy or pleasant.

Why Am I Seeing Things That Are Not There
A hallucination involves seeing , hearing, smelling or tasting something that doesnt actually exist . Hallucinations can be the result of mental health problems like Alzheimers disease, dementia or schizophrenia, but also be caused by other things including alcohol or drugs.
Don’t Minimize Their Experience
When your loved one is having a hallucination, avoid diminishing their experience. For example, you should avoid saying things such as “Don’t be silly Mom..there’s nothing there.” This belittles their experience because what they are seeing is very real indeed. Instead, acknowledging how your loved one may be feeling during the hallucination is a much better and caring approach.

A Doctors Exam May Be Beneficial
Older adults with dementia are sometimes unable to verbalize issues theyre having with their vision or other senses, especially during the later stages of dementia. Since there could be a valid medical reason for your loved ones hallucinations, schedule an appointment with a doctor or an appropriate specialist. This way, your loved one can be evaluated for cataracts, hearing problems, and other issues that could be affecting how he or she interprets things.

Von Willebrand Factor Dot Blot
Samples were initially centrifuged again for 20min at 15,000rpm to remove any particulate matter then diluted 1:400 in TBS. The standard was 7 serial dilutions of a reference homogenate, starting with a dilution of 1:100 in TBS. Prior to assembling the dot blot manifold, the membrane was soaked in TBS for at least 10min. One hundred microlitres of each sample was loaded onto the membrane after it had been placed in the dot blot vacuum manifold and was incubated for 75min. The manifold was then disassembled and the membrane washed for 3×10min in TTBS prior to blocking in 5% milk/TBS for 1h at room temperature with agitation. After a further 3×10-min washes in TTBS, the membrane was incubated overnight at 4°C with agitation, in rabbit polyclonal anti-vWF antibody diluted 1:3000 in 5% milk/TTBS. Following 3×30-min washes, the membrane was incubated in HRP conjugated goat anti-rabbit antibody diluted 1:5000 in 5% milk/TTBS for 1h at room temperature with agitation. After a further 3×30-min washes, 6ml of the substrate was added to each membrane, and after 4min, it was imaged in a BioRad imager . All samples were assayed in duplicate on each membrane and on two different membranes. The intraclass correlation coefficient for this assay was 0.69, indicating good consistency.

Tips For Managing Perceptual Difficulties And Hallucinations As They Happen
- Ask the person what is the matter. Listen carefully to the response and if possible, see if you can deal with the source of their distress
- Talk in a reassuring, slow, soothing way and explain what is happening but try not to contradict the person, as this may increase their distress
- Check they are wearing the correct glasses, and/or their hearing aid is working and has charged batteries
- Use distraction techniques. Suggest you both go into a different room take them to the kitchen to make a drink offer them a biscuit turn some music on or go out for a walk
- Hold the persons hand or sit close to them and stroke their arm
- Check for possible physical reasons for their distress. Could they have an infection, or be dehydrated or experiencing constipation? See your GP if in any doubt.

Hallucinations in seniors can be a serious problem for caregivers. Hallucinations are a symptom of many health problems which disproportionately affect seniors. Alzheimers Disease, Fronto-Temporal Dementia, and Parkinsons Disease can all cause hallucinations.
Hallucinations are sensory experiences that feel completely real but are produced by the mind. Hallucinations can be visual , auditory , or even tactile the form of visual experiences , auditory experiences , or even tactile experiences .
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.
