What Is Lewy Body Dementia?

Related Articles

Lewy body dementia (LBD), albeit less well-known than some other forms of dementia, is a prevalent form of progressive dementia that accounts for 5 to 10% of dementia cases globally, according to the Alzheimer’s Association. Lewy bodies, named for the neurologist Frederick Lewy who first noticed their impact, are aberrant tiny protein deposits that build up in the brain and cause the disease. These buildups prevent the brain from functioning normally, which causes it to degrade steadily.

  • LBD can manifest as either Parkinson’s disease dementia or dementia with Lewy bodies. The primary distinction between them is how each one develops the illness.
  • You might have a memory disease that resembles Alzheimer’s in dementia with Lewy bodies but later acquire mobility and other unique issues, like hallucinations.
  • Parkinson’s disease dementia is characterized by the development of dementia symptoms after having a movement problem that first resembles Parkinson’s.

However, both diagnoses will eventually appear to be the same. The majority of patients with LBD experience a comparable range of issues, such as changes in concentration and alertness, frequent visual hallucinations, shuffling gait, tremors, blank expressions, as well as different sleep abnormalities.

The signs and symptoms of Lewy body dementia might be quite similar to those of Alzheimer’s disease or Parkinson’s disease, but treatment options can differ significantly, making early detection of the ailment’s symptoms essential for managing the condition. And even though there is presently no treatment for LBD, there is still hope. Your freedom and quality of life can be extended with the support of crucial early treatment and self-help skills.

Dementia With Lewy Bodies Symptoms

The signs of Lewy body dementia worsen with time, often over a number of years, just like those of Alzheimer’s or Parkinson’s disease. Intellectual and motor functions also start to decline. There are signs, however, that show the disorder is LBD and not another condition, despite the parallels.

Although LBD patients experience cognitive decline, they are less likely to experience short-term memory loss linked to Alzheimer’s disease. They more frequently struggle with visual perception, such as judging and navigating distances, as well as executive processes like planning, decision-making, and organization. You might frequently trip or pass out as a result of this, or you might get lost in familiar places. Lewy body dementia can also affect sleep patterns and result in daytime drowsiness and insomnia.

At least two of the following four characteristics will also be present in people with Lewy body dementia:

alterations or “fluctuations” in awareness and focus You fluctuate between being attentive and seeming sleepy, perplexed, or fixated on nothing. These episodes can come on suddenly and last for a short while or for several hours.

spontaneous motor symptoms resembling Parkinson’s disease, including sluggishness, stiffness, trembling, loss of facial expression, or irregular walking.

Recurrent visual hallucinations or delusions, such as talking to deceased loved ones or seeing forms, colors, people, or animals that aren’t there.

Symptoms of REM sleep behavior disorder include physically moving your limbs, talking while you sleep, screaming, hitting, or even getting up and doing things during the day.

In summary, Lewy body dementia, rather than another type of dementia, may be present if you or a loved one is suffering cognitive decline without the classic problems with recent memory.

Additional Typical Symptoms

You might also encounter the following in addition to cognitive deterioration, hallucinations, and motor and sleep issues:

  • Depression.
  • conducting regular duties is becoming more difficult. For a person with LBD, previously simple tasks could now be challenging.
  • variations in autonomic functions. This includes problems with heart rate, body temperature, urination, constipation, and swallowing.
  • Alzheimer’s, Parkinson’s, and Lewy body dementia
  • Understanding how these conditions overlap is important since Lewy body dementia is frequently misdiagnosed as both Parkinson’s and Alzheimer’s.

Identifying LBD

It might be difficult to definitively confirm a diagnosis of Lewy body dementia because many of the symptoms can potentially be brought on by other diseases. Bring a friend or family member with you to appointments, and make careful notes about how and when your symptoms arise.

Since the Lewy bodies themselves can only be discovered by autopsy, a doctor’s knowledge of the disease’s distinctive features is crucial for making an accurate diagnosis. Your physician or specialist could:

Examine your symptoms, taking note of things like how long you’ve had memory issues and whether you experience hallucinations or sleep disorders.

Evaluate your mental faculties, including your attention span, ability to follow directions, language, organization, and communication skills. To rule out other potential causes of symptoms, perform a physical examination, including blood tests and a review of current medications.

Take a brain scan. A brain scan can identify mental decline but not the actual Lewy body; however, it may aid in diagnosis.

Managing a Diagnosis

Receiving a dementia diagnosis can be quite stressful. Even though there is currently no drug that is specially designed to treat LBD, doctors are able to treat many of its symptoms. Numerous self-help techniques can also aid in the improvement of symptoms.

Anger, worry, and uncertainty about the future are just a few of the many powerful and terrible feelings you may experience if you have been diagnosed with LBD.

Adaptation takes time. Giving oneself time to acclimate is vital, just like with any significant life adjustment. As you go, be prepared for the ups and downs. For a while, you can feel as though you’ve adjusted to your new circumstances, but then tension may overwhelm you once again.

Request assistance. Lewy body dementia makes daily life challenging, but there is support available. The more help you receive from friends and family, the easier it will be for you to manage your symptoms.

Tell your loved ones what you want. When you are unable to make decisions for yourself, it is never simple to discuss how you want your medical care to be handled. However, it’s crucial to communicate to your loved one what is significant to you. The quality of your life in the future and the load on your family can both be improved by reflecting on your decisions today.

Reducing The Rate Of Symptom Development

The progression of LBD symptoms can be slowed down with the help of the same healthy lifestyle modifications that are used to prevent dementia.

  • Get regular exercise to help your brain create new connections, maintain existing ones, and prevent cognitive decline.
  • Social interaction and face-to-face interactions with others can both assist your cognitive function.
  • A diet that is good for the brain can lower inflammation and improve communication between brain cells.
  • Your cognitive abilities can be improved by using your mind, learning new things, and presenting cognitive challenges.
  • A good night’s sleep can remove poisons from the brain and prevent the formation of harmful plaques.
  • Controlling stress can prevent nerve cell development and halt shrinkage in a crucial memory region of the brain.

Coping Strategies For People With Lewy Body Dementia

Since the primary goal of LBD treatment is symptom management, it is beneficial to start acting as proactively as you can straight soon. This entails contacting family members for assistance, engaging with your doctor to manage symptoms, and adapting your lifestyle to the disease’s consequences.

Educate yourself. Do as much research as you can on dementia with Lewy bodies and how, given your health history, age, and lifestyle, it is likely to affect you in particular. Knowing more will give you a sense of control and help you better manage symptoms.

Be less stressed. Numerous LBD symptoms can be exacerbated by stress and worry. Try relaxing methods like music therapy, meditation, and deep breathing exercises to find ways to unwind.

Exercise can not only enhance physical performance but also reduce stress and improve your attitude. Find the things that you enjoy doing because any physical exercise that increases your heart rate might be healthy.

Appreciate puzzles and games. Crossword and Sudoku puzzles, card games like Scrabble, and Sudoku can all help your brain stay active and may even slow cognitive loss.

Avoid afternoon naps and limit coffee intake. These actions, along with regular daytime exercise, can aid in preventing evening restlessness.

Do daily activities that would make you happier. Dementia patients are still able to enjoy themselves and engage with others. Feed your spirit by engaging in activities you enjoy, whether it’s playing with your grandchildren, enjoying the arts, being in nature, or engaging in a favorite pastime.

Find your mission and meaning. Find new methods to invest yourself in yourself or keep up with the pursuits that were significant to you before your diagnosis. You can think about helping out with a cause that matters to you, getting involved in a religious group, or even taking care of your pets—anything that makes you feel wanted and satisfied.

Treatment LBD treatments work to manage the hallucinations, sadness, and sleep disruptions that are a part of the disorder’s cognitive, motor, and psychiatric symptoms.

Medication

Drugs used to treat Alzheimer’s disease and Parkinson’s disease may also be used to treat LBD, providing relief from the cognitive, motor, and behavioral symptoms. The reactions of some LBD patients to specific drugs, however, can be significantly different from those of patients with Alzheimer’s disease or Parkinson’s disease. Another factor making a precise early diagnosis so crucial is the fact that some drugs may possibly make LBD symptoms worse.

Work carefully with your doctor to determine the medications and dosages that are most beneficial for you, and always let them know if you or a loved one has any negative effects.

  • Cholinesterase inhibitors, such as donepezil and rivastigmine, may be prescribed by your doctor to treat the cognitive symptoms of Lewy body dementia. They are also capable of effectively treating other psychiatric symptoms, such as visual hallucinations.
  • Some patients with LBD may benefit from levodopa in terms of mobility and rigidity.
  • Treatment options for REM Sleep Behavior Disorder and other sleeping issues include melatonin or clonazepam.
  • Depression, which is frequent with LBD, may be treated with antidepressants such as SSRIs.

Lewy Body Dementia Treated With Neuroleptics

Strong tranquilizers, known as neuroleptics or antipsychotics, are sometimes provided to dementia patients in order to address hallucinations or other behavioral issues. However, neuroleptics may be particularly hazardous if consumed by individuals with LBD. This medicine class can have side effects similar to Parkinson’s disease, such as rigidity, immobility, and the inability to function or communicate.

It may be preferable to suffer the hallucinations than to put up with the adverse effects of the medicine if you or a loved one with Lewy body dementia is not very bothered by them. However, if you and your doctor do choose to use a neuroleptic, you should proceed with the utmost caution and have regular, close monitoring.

Providing Care For A Person With Lewy Body Dementia

Establish a routine. Having dependable routines, especially around meal and sleep times, might be helpful for someone with LBD.

Create a bedtime routine. Create relaxing sleep routines that are distant from the noise of the television, dinner preparation, and occupied family members. Exercise is encouraged, caffeine intake is restricted, and daytime naps are discouraged from assisting reduce nighttime restlessness.

Alter the tasks. Break projects down into manageable steps and concentrate on success rather than failure.

Walk side by side. A win-win activity is going on a stroll with a patient who has LBD. Exercise outside and getting outside are important for the patient’s health and your own mental state.
