Can Vascular Dementia Cause Hallucinations

What Is The Differential Diagnosis Of Late

Dementia Issues – Hallucinations

The most common causes of new-onset psychosis in later life are dementia-related syndromes with psychosis, delirium or drug-induced psychosis, and primary psychiatric disorders, most commonly depression. Dementia is the greatest risk factor for development of psychotic symptoms in the geriatric population both as a result of dementia itself and through an increased vulnerability to delirium.

Medication For Dementia Hallucinations

If the hallucinations are severe, physicians can prescribe medications to treat hallucinations. Different drugs can do the job such as:


This is one of the first drugs that has even been approved to treat hallucinations that relate to Parkinsons disease dementia.

Antipsychotic medication

These can treat hallucinations by offering a calming effect which makes the hallucinations less distressing. The drugs can also reduce or eliminate the frequency with which they occur.

Cholinesterase Inhibitors

These are medicines that doctors will give people to treat both hallucinations and dementia. They increase levels of specific neurotransmitters in the brain which helps to boost cognition as well as alertness. They also have the potential to reduce hallucinations.

It is also recommended that caregivers seek out support because dealing with persons who have hallucinations and dementia is not an easy task.

This is because you may end up dealing with feelings of frustration, exhaustion, guilt, distress, and exasperation.

Seeking support helps you to effectively deal with such so that you can be in the best possible position to look after the individual with dementia.

What Are The Most Common Types Of Progressive Dementia And Their Characteristics

Dementing illnesses can be placed into multiple diagnostic categories. However, there is emerging evidence that these subtypes overlap.

Dementia of the Alzheimer’s type is the most common dementing disorder, comprising at least two thirds of dementia cases. It affects 1% to 2% of people older than 60 years. The prevalence doubles every 5 years after the age of 60, which translates into a prevalence of approximately 50% of individuals older than 85. The main risk factors for DAT are age and family history, although other risk factors include a history of head trauma and Down syndrome. The early stages of DAT are characterized by a subtle loss of short-term memory, which progresses into word-finding and naming difficulties, often manifesting as vague speech and circumlocution. As DAT progresses, so does cognitive impairment; motor apraxias may develop. In the late stages, judgment becomes impaired, personality changes, and social withdrawal may occur.

Vascular dementia is one of the most common causes of dementia, comprising 15% to 20% of cases. Typically, it is characterized by a stepwise decline in cognitive function and is accompanied by focal neurologic deficits. Risk factors are the same as for other vascular and embolic diseases. Stroke is an important contributor to dementia, yielding a 9-fold increase in risk of dementia. Vascular defects from a single infarct, multiple infarcts, or white matter ischemia may cause dementia.

Caring For Someone With Dementia

Caring for a person with dementia can be physically and emotionally demanding. Anger, guilt, frustration, discouragement, worry, grief and social isolation are common.

Learn as much about vascular dementia as you can. Ask the primary care doctor or neurologist about good sources of information. Your local librarian also can help you find good resources.

Take care of yourself. See your doctors on schedule, eat healthy and exercise.

Seek support. People with dementia and their families benefit from counseling or local support services. Contact your Alzheimers Association local affiliate to connect with support groups, resources, referrals, home care agencies, residential care facilities, telephone help lines and educational seminars.

Encourage. You can help a person cope with vascular dementia by listening, reassuring them that life can be enjoyed and helping them retain dignity and self-respect.

Provide a calm environment. It can reduce worry and agitation. Establish a daily routine that includes comfortable activities for the person with vascular dementia.

New situations, excess noise, large groups of people, being rushed to remember or being asked to do complicated tasks can cause anxiety. As a person with dementia becomes upset, the ability to think clearly declines even more.

Paying attention to your needs and well-being is one of the most important things you can do for yourself and the person in your care.

What Is Involved In The Workup Of Late

What Is Vascular Dementia

The first step in determining the etiology of late-onset psychosis is to search for underlying causes of delirium. This workup generally includes identification of potentially offending prescription medications, especially anticholinergic and sedative-hypnotic medications; exclusion of an infectious etiology ; and exclusion of other metabolic causes. Exacerbation of chronic illnesses, such as congestive heart failure, chronic obstructive pulmonary disease, renal insufficiency, and anemia, may also cause metabolic changes responsible for delirium.

Once delirium is excluded as an etiology, the next step is to determine whether the psychotic symptoms stem from a dementia or from another psychiatric disorder. At times, due to comorbidity and overlapping features, it may be difficult to differentiate between dementia and other psychiatric etiologies. For example, an individual with dementia may report depressed mood and/or meet the criteria for depression, and an individual with depression and schizophrenia may perform poorly on cognitive testing. Notwithstanding these difficulties in establishing a diagnosis, careful history-taking with the use of collateral information from family members and others, as well as functional and cognitive assessments, can be helpful in establishing a working diagnosis and a treatment plan.

How Is Vascular Dementia Linked To Stroke

When you have a stroke, the blood supply to part of your brain is cut off, killing brain cells. The damage from a stroke can cause problems with memory and thinking. For many people, these problems improve over time. If the problems dont improve or get worse this may be a sign of vascular dementia.

Vascular dementia can also be caused by a series of small strokes. These result in lots of small areas of damage in your brain. Often, these strokes can be so small that you don’t know you are having them. These are known as silent strokes.

Sometimes symptoms of vascular dementia can be confused with the effects of stroke. Both stroke and vascular dementia can cause problems with memory, thinking and mood. Strokes happen suddenly while the symptoms of vascular dementia often get worse over time. The difference is that vascular dementia gets worse over time. If youre unsure, go to see your GP.

Lifestyle Changes To Improve Vascular Dementia Symptoms

A diagnosis of dementia is scary. But its important to remember that many people with dementia can lead healthy, fulfilling lives for years after the diagnosis. Dont give up on life! As much as possible, continue to look after your physical and emotional health, do the things you love to do, and spend time with family and friends.

The same strategies used to keep your brain healthy as you age and prevent the onset of dementia can also be used to improve symptoms.

Find new ways to get moving. Research suggests that even a leisurely 30-minute walk every day may reduce the risk of vascular dementia and help slow its progression. Regular exercise can also help control your weight, relieve stress, and boost your overall health and happiness.

Create a network of support. Seeking help and encouragement from friends, family, health care experts, and support groups can improve your outlook and your health. And its never to late to make new friends and expand your network.

Eat for heart health. Heart disease and stroke share many of the same risk factors, such as high LDL cholesterol , low HDL cholesterol , and high blood pressure. Adopting a heart-healthy diet may help to improve or slow down your dementia symptoms.

Make it a point to have more fun.Laughing, playing, and enjoying yourself are great ways to reduce stress and worry. Joy can energize you and inspire lifestyle changes that may prevent further strokes and compensate for memory and cognitive losses.

Treatment And Other Helpful Guidelines


Mrs. Ws treatment team worked with her husband and her to preserve her independence, self-esteem, and quality of life as fully as possible. Although no medications carry a specific FDA indication or have been proven effective in reducing PCA symptoms, doctors often prescribe cholinesterase inhibitors such as donepezil , rivastigmine , or Razadyne or the glutamatergic medication memantine . This makes sense because AD plaques and tangles are so often the underlying cause of PCA.

Modifying the Home

As with AD, the clinical management of PCA goes far beyond the use of medication. A geriatric care manager in communication with Mrs. Ws treatment team helped to make her home a safer place for someone with her visual difficulties. Clutter was removed, and labels were applied to drawers so that she could find things more easily. Throw rugs were removed or replaced with non-skid floor coverings. Stickers were put on glass doors and large windows so that Mrs. W would see them more easily. ;Adequate lighting was arranged in all rooms with attention to reducing glare.

Its Often Difficult For A Person With Psychosis To Know When Its Happening

Its never obvious to the patient when they are in the midst of a hallucination or delusionafter all, they believe that experience is very real. Symptoms of hallucinations and delusions can often be difficult for patients to describe, or even realize they’re experiencing, which can make detecting them more challenging for both caregivers and clinicians, Dr. Foff explains. The best thing patients and caregivers can do is to communicate with one another. Loved ones should listen closely to what the patient thinks and feels, advises Dr. Foff. Rather than pushing back or correcting them, ask thoughtful questions about what they are seeing, hearing, or feeling. If they describe experiences that that seem indicative of psychosis, report this to their doctor at once, she adds.

What Causes Hallucinations


Visual hallucinations are usually caused by damage to the brain. They are more common in people with dementia with Lewy bodies and Parkinsons disease dementia. People with Alzheimers disease can also have hallucinations.

Hallucinations can also be caused by physical illness including fever, seizure, stroke, migraine and infection. Diseases that cause inflammation and infection, such as pneumonia, can interfere with brain function and cause delirium. Some people with delirium will have hallucinations. Delirium is a medical emergency.

Hallucinations are a rare side effect of many medications. The drugs for Parkinsons disease can often trigger hallucinations. Speak to your GP before making any changes to medication.

Some people with worsening vision start to see things that arent there because of their deteriorating sight and not from any other condition, such as dementia or a mental health problem. This is called Charles Bonnet syndrome.

What To Do After A Tia

If you suspect that your older adult has had a mini stroke, take them to a hospital immediately and describe all the symptoms they experienced.

To reduce the risk of a major stroke in the near future, doctors may recommend medication to prevent blood clots from forming or to treat high blood pressure, high cholesterol, or heart disease. Depending on the situation, surgery could also be recommended.

In the longer term, help your older adult lower their stroke and vascular dementia risk by improving their lifestyle.

A healthy lifestyle means not smoking, not drinking too much, eating a healthy diet, and exercising regularly.

It is also important to keep other health conditions under control, especially high blood pressure and high cholesterol.

How Vascular Dementia Develops

Symptoms of vascular dementia can appear suddenly if they are caused by a single stroke, or if they are caused by silent strokes they may appear gradually over time.;Vascular dementia sometimes develops in steps, so that symptoms will stay the same for a while and then suddenly get worse. These steps are usually due to new strokes.;

When Trouble Might Occur

Visual hallucinations are one of the hallmark symptoms in Lewy body dementia and often occur early in the illness. In other dementias, delusions are more common than hallucinations, which occur well into the disease cycle, if at all, and are less often visual.

Fluctuating good days and bad days are another hallmark of LBD. On a good day, thinking is clear, and these illusions, hallucinations and delusions may not occur; on a bad day, they may be intense.

As LBD progresses, these types of symptoms may first intensify, then later burn out.;

In dementia, symptoms always change, so what a person experiences this month may not be happening the next month, though such distressing symptoms seem to last an eternity for the caregiver.

Selection Of Patients With Dementia

Eighty patients over the age of 60 years who fulfilled DSM IV criteria for dementia were recruited. Seventy five patients were obtained from a community dwelling population of patients referred to local old age psychiatry and geriatric medicine services for evaluation of possible dementia. Five patients were recruited from a dementia research clinic. The research was approved by the local ethics committee and all patients, as well as their nearest relative, gave informed consent.

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.

Currently There Is No Approved Treatment For Dementia

Lewy body dementia

Though there are several medications on the market for the treatment of conditions that can trigger dementia , currently there is no FDA-approved treatment specifically for dementia-related psychosis . According to Dr. Isaacson, over 40% of patients with these symptoms are actually not treated at all. Traditionally, doctors have prescribed anti-psychotic medications off-label to treat hallucinations and delusions. But these meds can have concerning side effects for dementia patients, including impaired motor function and an increased risk of death.

Thankfully, there is hope on the horizon for a safer pharmacologic treatment. In July 2020, the FDA accepted and began reviewing Nuplazid specifically to treat the hallucinations and delusions thar are associated with dementia-related psychosis. The drug has already made it through three phases of clinical trials and may be available as soon as early summer 2021.

If the person is having episodes of distress which become more regular, or worsen, make an appointment with the GP, so they can rectify or rule out any potentially treatable causes.

The GP will want to know if anything triggers the changes in their behaviour; what the signs and symptoms are; what time of the day the behaviour occurred; for how long; and what, if anything, helps to reduce or stop the behaviour. Try to take this information with you if possible.

The GP should have the persons medical history and diagnosis available but, if not, some brief notes on this and any changes to medication would be useful.
