Lewy Body Dementia (LBD) is a complex and debilitating neurodegenerative disorder that affects millions of people worldwide. It is often misunderstood and misdiagnosed, making it crucial for individuals and their families to gain a deeper understanding of this condition.
In this comprehensive guide, we will explore the intricacies of Lewy Body Dementia, its symptoms, potential causes, available treatments, and effective coping strategies.
Lewy body Dementia (LBD) is a type of progressive dementia that leads to a decline in thought, reasoning and independent functions due to abnormal microscopic deposits that damage brain cells as time passes.
About Lewy Body dementia
Most experts estimate that Lewy body dementia (LBD) is the third most common cause of dementia after Alzheimer’s disease and vascular dementia, accounting for 10 to 25 percent of cases.
The brain-specific abnormality associated with Lewy body dementia (LBD) was named by Frederich H. Lewy, M.D., a neurologist who invented them while working in Dr. Alois Alzheimer’s laboratory during the early 1900’s. Alpha-synuclein proteins, Lewy’s body main components, are widely found in the brain, but their normal functions are not yet known.
Lewy Body Dementia Symptoms
Symptoms of LBD can vary, you can find all of these symptoms or only a few. The symptoms of LBD include:
What are the early warning signs of Lewy Body Dementia?
Lewy Body Dementia can manifest in a variety of ways, with symptoms varying from person to person. Some of the common early warning signs include:
- Visual hallucinations
- Fluctuating cognitive abilities
- Motor impairment
- Sleep disturbances
- Mood changes
- Memory problems
Cognitive symptoms in LBD sufferer
Loss of severe thinking ability that interferes with a person’s capacity in conducting daily activities. Dementia is a key symptom of LBD and usually it has to be impaired by attention, visual and spatial ability (assessing distance and depth or failure in identifying an object), difficulty in making plans, multitasking, problem solving, and reasoning.
Memory impairment does not occur at first, but appears as the disease progresses. Dementia can also include changes in mood and behavior, poor judgment, loss of initiative, confusion over time and place, and difficulties with language and numbers.
Cognitive flunctuations is one of Lewy Body Dementia Symptoms.
Changes in concentration, attention, unexpected alertness from day to day and sometimes occurs throughout the day. People with LBD appear sleepy and lethargic or asleep for a few hours in the daytime despite having enough sleep at night.
The LBD sufferer will also have a plot of irregular, unclear, or unreasonable ideas at a time. The LBD sufferer seemed better one day, but worse the next day. Symptoms of cognitive fluctuations often occur in LBD sufferer and become one of the differentiator of Alzheimer’s.
80 percent of people with LBD has visual hallucinations or seeing things that are not actually present. Non-visual hallucinations, such as hearing or smelling the scent of something that is not actually present, it can occur, but less frequently than visual hallucinations.
Motion Disorder in LBD Sufferer
Motion disorder is one of Lewy Body Dementia Symptoms.
Some LBD sufferer can experience a significant movement interruption in the early stages, but some of the LBD sufferer has not experienced it until a few years. At first, the symptoms of movement disorder may occur very mild and often overlooked like a handwriting change.
Sleep disturbances in LBD sufferer
In LBD sufferer, sleep disorder often occurs, but often not diagnosed. Sleep-related disorders experienced by LBD sufferer, among others:
REM Sleep Behavior Disorder (RBD)
REM Sleep Behavior Disorder (RBD), which is a condition in which LBD is likely to portray a dream while sleeping like talking while sleeping, a rough / great movement when sleeping or to fall from the bed. RBD can be an early symptom in some people and occur on a chronic basis before other LBD symptoms arise.
Excessive Daytime Sleepiness
Excessive daytime sleepiness is one of Lewy Body Dementia Symptoms.
Excessive Daytime Sleepiness, which is sleep for 2 hours or more in the daytime, although it already has enough sleep time at night.
Insomnia, which is difficult to sleep or often wakes up while sleeping.
Restless Leg Syndrome
Restless Leg Syndrome is a condition in which the sufferer feels unpleasant or unusual sensation in his feet at rest, giving rise to the urge to move and stomp the feet.
Behavior changes and Mood on LBD Sufferer
Depression, that is, feelings of sadness, worthlessness, or inability to enjoy the activity continuously and often accompanied by difficulties to sleep and eat.
Apathy, which is a lack of interest in normal daily activities and less social interaction.
Anxious, a deep concern or fear of a situation or future. The complainant can ask the same question repeatedly or become angry or afraid when the worries do not exist.
Agitation, that is the anxiety that can look like pacing, hand wringing, repeating words or phrases, and irritability.
Delusions, that is has a very strong belief in something that does not conform to reality or it is not based on evidence such as thinking that long-dead relatives are still alive or his spouse is having an affair.
Paranoid, that is to have an extreme suspicion and irrational like a person’s suspicion of taking or hiding something.
LBD sufferer can also undergo significant changes to the part of the nervous system that regulate the automatic functioning of the body, such as the heart, glands, and muscles so that the LBD sufferer can experience other symptoms such as the following:
- Body temperature change
- Blood pressure disorders
- Often falls
- Sensitive to cold and heat.
- Se**xual dysfunction
- Urinary incontinence
- Decreased smell sense ability
Lewy Body Dementia Causes
The exact cause of LBD remains unknown, but researchers believe that a combination of genetic and environmental factors may contribute to its development. Abnormal accumulation of alpha-synuclein protein in the brain is a hallmark of LBD and is believed to play a significant role in its pathogenesis.
Are there any risk factors associated with Lewy Body Dementia?
While anyone can develop LBD, certain risk factors may increase the likelihood of its occurrence. These include:
- Age (usually affects individuals over the age of 50)
- Family history of LBD or other neurodegenerative disorders
- Gender (men are slightly more prone to LBD than women)
- Previous head injuries or trauma
Lewy Body Dementia Diagnosis
Diagnosing LBD can be challenging, as its symptoms overlap with other neurodegenerative disorders like Alzheimer’s and Parkinson’s. A comprehensive evaluation that includes medical history, physical examination, cognitive tests, and brain imaging is essential for an accurate diagnosis.
Healthcare professionals may also consider the presence of Lewy bodies, abnormal protein deposits in the brain, to confirm the diagnosis.
What are the available treatment options for Lewy Body Dementia?
Currently, there is no cure for LBD. Treatment primarily focuses on managing symptoms and improving the patient’s quality of life. A multidisciplinary approach involving medication, therapy, lifestyle modifications, and caregiver support is often recommended.
Medications such as cholinesterase inhibitors and Parkinson’s disease medications may be prescribed to alleviate cognitive and motor symptoms.
How can caregivers support individuals with Lewy Body Dementia?
Caring for someone with LBD can be physically and emotionally demanding. Here are some tips for caregivers:
- Educate yourself about LBD to better understand the condition
- Seek support from healthcare professionals, support groups, and respite care services
- Establish a structured routine and provide a safe and supportive environment
- Encourage regular physical exercise, mental stimulation, and a healthy diet
- Take care of your own physical and emotional well-being to prevent burnout
FAQs about Lewy Body Dementia
Can Lewy Body Dementia be prevented?
Currently, there is no known way to prevent LBD. However, leading a healthy lifestyle, engaging in regular exercise, maintaining social connections, and managing underlying health conditions may help reduce the risk.
Is Lewy Body Dementia hereditary?
While LBD can have a genetic component, it is not always hereditary. In some cases, individuals with a family history of LBD or other neurodegenerative disorders may be at a slightly higher risk.
Are there any experimental treatments or ongoing research for Lewy Body Dementia?
Yes, researchers are actively studying LBD to uncover new treatment options. Experimental therapies such as immunotherapy, gene therapy, and stem cell therapy are currently being explored in clinical trials.
Lewy Body Dementia is a complex and devastating disease that impacts the lives of individuals and their families. While there is no cure for LBD at present, gaining a deeper understanding of the condition, recognizing its early warning signs, and implementing effective management strategies can greatly improve the quality of life for those affected.
By spreading awareness, supporting ongoing research, and providing compassionate care, we can strive to make a difference in the lives of individuals living with Lewy Body Dementia.
