Helping A Senior With Visuoperceptual Difficulties
If visual processing is the cause of the problem, caregivers can help seniors manage their eyesight and their visual environments. Aging adults should have regular optometrist appointments, and they may need different glasses for different activities. At home, make sure your loved ones environment is as easy to see as possible. The more familiar seniors are with their environments, the less likely they are to slip and injure themselves. To increase environmental comfort, keep the arrangement and décor of rooms consistent. Use colors to draw the eye to important spatial information. For example, using a plate that contrasts with the color of the table can make mealtimes easier. Bright, even lighting can also help.;

Risk Factors For Psychosis
Not everyone with Parkinsons will develop hallucinations or delusions, but there are several things can increase your risk:
- Dementia;or impaired memory
- Depression: Individuals suffering from depression and PD are at a greater risk. In addition, severe depression alone can cause psychosis.
- Sleep disorders, such as vivid dreaming. Individuals commonly report vivid dreaming prior to the onset of psychosis. Other associated sleep disturbances include REM;sleep disorder and general insomnia.
- Impaired vision
- Use of PD medications
The Difference Between Hallucinations And Delusions
- Hallucinations are defined as false perceptions. They are very real to the person experiencing them. One example is seeing bugs crawling on the floor, though they are not there. Nothing you say to the person having that experience will convince him/her otherwise.
- Delusions, per the National Institute of Health, are strongly held fixed beliefs or opinions not based on evidence. These false beliefs and opinions can be about people or things. They can also be about the person with dementia. Some common types of delusions include stealing, believing there is an intruder, and infidelity. Paranoia is a form of delusion.

How To Talk To Someone With Hallucinations Or Delusions
- It is usually not helpful to argue with someone who is experiencing a hallucination or delusion. Avoid trying to reason. Keep calm and be reassuring.
- You can say you do not see what your loved one is seeing, but some people find it more calming to acknowledge what the person is seeing to reduce stress. For example, if the person sees a cat in the room, it may be best to say, “I will take the cat out” rather than argue that there is no cat.

Keep It From Happening Again
You can do some things to help make hallucinations and delusions less likely:
- If your loved one needs glasses, a hearing aid, or dentures, try to make sure they wear them. Check that their glasses are clean and the right ones for the distance. Make sure their hearing aid works and is turned on. Have their eyes and ears checked regularly.
- Make sure all rooms are well-lit. Turn on lights to get rid of shadows and reflections. Shut off sounds that might confuse them, such as noise from a TV, radio, furnace, or air conditioner.
- Keep their home and routine as close to what theyâre used to as you can. Have them be with people they know as much as possible.
- If the same thing always causes them to have problems, change it or take it away if you can.

Dealing With Delusions In The Elderly
Delusions among dementia patients typically result from their cognitive impairment. They occur when a senior tries to make sense of a situation, but their confusion and memory problems make it impossible.
They end up filling a hole in a faulty memory with a delusion that makes sense to them, Gwyther says. For example, if a loved one cannot find their purse, they may conclude it is missing because someone stole it. This phenomenon is called confabulation.
Delusions can be frightening for the person living with dementia, but they can also be very hurtful for caregivers when they are the targets. Recognize that the elderly individual is living in a world that doesnt make sense to them and is likely scared. Do not take any accusations personally or respond with logical explanations. Instead, reassure the person and avoid asking questions that may only cause more confusion. If they are looking for an item, tell them you will help them find it. In cases where a loved one regularly misplaces an item and becomes agitated over the loss, the Alzheimers Association recommends purchasing a duplicate of the item to quickly resolve the issue until the original is found.
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.

What Is A Hallucination
A hallucination can involve your loved one smelling, hearing, seeing, tasting, or feeling something that isn’t there. Your loved one may see the face of a deceased loved one in the distance or see bugs crawling on their hand. In some instances, your loved one could hear an old friend talking and may even engage in a conversation with the imagined individual.;
Hallucinations are triggered by changes in the brain that typically happen during the later or middles stages of the dementia journey. Certain types of dementia are more commonly associated with hallucinations. For example, hallucinations are more common with Parkinson’s dementia and dementia with Lewy bodies, but can also be experienced by those with Alzheimer’s disease.;
Coping With Hallucinations In Elderly Dementia Patients
When it comes to handling a seniors hallucinations, Marion Somers, Ph.D., author of Elder Care Made Easier: Doctor Marions 10 Steps to Help You Care for an Aging Loved One, suggests joining them in their version of reality. Ask the dementia patient about what they are experiencing as if it is real so you can more effectively defuse the situation. Refrain from trying to explain that what they are seeing or hearing is all in their head. Otherwise, youre going to aggravate them, and you dont want to increase the level of agitation, Somers advises.
Reassure them by validating their feelings. Say something like, I see that youre upset. I would be upset if I saw those things, too. Tell them that they are safe with you and you will do everything in your power to help them feel secure.
A comforting touch, such as gently patting their back, may help the person turn their attention to you and reduce the hallucination, according to the Alzheimers Association. You also can suggest that they move to a different room or take a walk to get away from whatever may have triggered the experience.
Hallucinations arent just a symptom of Alzheimers disease, either; they are also very common in seniors with Lewy body dementia. Furthermore, poor eyesight, hearing loss, certain medications, dehydration and urinary tract infections can all contribute to hallucinations.

Why Do Changes In Perception Occur
We understand the world through our senses. There are five senses: hearing, sight, smell, taste and touch. These senses collect information and send it to the brain, which uses it to make sense of the world around us.
For some people living with dementia, their brain misinterprets the information from their senses. This is called changes in perception, and leads to them misunderstanding the world around them, or, in more rare instances, the person having hallucinations.
Changes in perception can also happen because of physical changes in the brain or the sensory organs, such as our eyes or ears. The most common example of this, is someones vision or hearing getting worse as they get older.
In this leaflet, we will look at what exactly we mean by changes in perception and hallucinations, as well as suggesting why these things might be happening. Lastly, we will suggest some ways to prevent or manage the type of misperceptions that can occur in people living with dementia.

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.

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.

Alzheimer’s And Hallucinations Delusions And Paranoia
Due to complex changes occurring in the brain, people with Alzheimer’s disease may see or hear things that have no basis in reality.
- Hallucinations involve hearing, seeing, smelling, or feeling things that are not really there. For example, a person with Alzheimer’s may see children playing in the living room when no children exist.
- Delusions are false beliefs that the person thinks are real. For example, the person may think his or her spouse is in love with someone else.
- Paranoia is a type of delusion in which a person may believewithout a good reasonthat others are mean, lying, unfair, or out to get me. He or she may become suspicious, fearful, or jealous of people.
If a person with Alzheimers has ongoing disturbing hallucinations or delusions, seek medical help. An illness or medication may cause these behaviors. Medicines are available to treat these behaviors but must be used with caution. The following tips may also help you cope with these behaviors.
