Cognitive Symptoms Of Lewy Body Dementia

LBD causes changes in thinking abilities. These changes may include:

• Visual hallucinations, or seeing things that are not present. Visual hallucinations occur in up to 80 percent of people with LBD, often early on. Nonvisual hallucinations, such as hearing or smelling things that are not present, are less common than visual ones but may also occur.
• Unpredictable changes in concentration, attention, alertness, and wakefulness from day to day and sometimes throughout the day. Ideas may be disorganized, unclear, or illogical. These kinds of changes are common in LBD and may help distinguish it from Alzheimer’s disease.
• Severe loss of thinking abilities that interfere with daily activities. Unlike in Alzheimer’s dementia, memory problems may not be evident at first but often arise as LBD progresses. Other changes related to thinking may include poor judgment, confusion about time and place, and difficulty with language and numbers.

Dementia describes a cluster of symptoms linked to an ongoing cognitive decline. There are many different types of this mind-robbing condition, with Lewy body dementia being the second most common type of progressive dementia after Alzheimer’s disease. Its triggered by the development of protein deposits, called Lewy bodies, in nerve cells in the brain regions involved in thinking, memory and movement.

Sure Signs You May Have Dementia According To Mayo Clinic

The warning signs you’re getting dementia can sneak up on you. “The word ‘dementia’ is an umbrella term used to describe a set of symptoms, including impairment in memory, reasoning, judgment, language and other thinking skills,” says the Mayo Clinic. “Dementia usually begins gradually, worsens over time and impairs a person’s abilities in work, social interactions and relationships” and “symptoms vary depending on the cause, but common signs and symptoms include” the following, says the Mayo Clinic.

Whats The Difference Between Progressive Supranuclear Palsy And Parkinsons

People with PSP generally progress more rapidly than people with Parkinsons. A person with Parkinsons tends to lean forward while a person with PSP tends to lean backward. Tremors are common in people with Parkinsons and rare in people with PSP. Speech and swallowing abnormalities are more severe and show up sooner in those living with PSP.

For more information on progressive supranuclear palsy, read this fact sheet and insights from the CurePSP organization website.

Questions You May Be Asked May Include:

• When did your memory problems begin?
• What medications, including prescription drugs, over-the-counter drugs and dietary supplements, do you take and in what doses?
• Have you recently started a new drug?
• What tasks do you find difficult?
• What have you done to cope with memory problems?
• How much alcohol do you drink?
• Have you recently been in an accident, fallen or injured your head?
• Are you having difficulty sleeping?
• Have you recently been sick?
• Do you feel sad, depressed or anxious?
• Have you recently had a major loss, change or stressful event in your life?

You may have a general physical exam, blood tests or brain imaging. These can help identify reversible causes of memory problems and dementia-like symptoms.

You might be referred to a specialist who can diagnose dementia or memory disorders, such as a neurologist, psychiatrist, neuropsychologist or geriatrician. You may need additional testing, known as a neuropsychological test, to determine whether your thinking changes are normal for your age or not.

You May Have Memory Loss

“which is usually noticed by a spouse or someone else,” says the Mayo Clinic. “Often, memory loss that disrupts your life is one of the first or more-recognizable signs of dementia. Other early signs might include:

• Asking the same questions repeatedly
• Forgetting common words when speaking
• Mixing words up saying ‘bed’ instead of ‘table,’ for example
• Taking longer to complete familiar tasks, such as following a recipe
• Misplacing items in inappropriate places, such as putting a wallet in a kitchen drawer
• Getting lost while walking or driving in a familiar area
• Having changes in mood or behavior for no apparent reason”

Stiffness And Slow Movement

Parkinsons disease mainly affects adults older than 60. You may feel stiff and a little slow to get going in the morning at this stage of your life. This is a completely normal development in many healthy people. The difference with PD is that the stiffness and slowness it causes dont go away as you get up and start your day.

Stiffness of the limbs and slow movement appear early on with PD. These symptoms are caused by the impairment of the neurons that control movement. A person with PD will notice jerkier motions and move in a more uncoordinated pattern than before. Eventually, a person may develop the characteristic shuffling gait.

You May Have Difficulty Handling Complex Tasks

“Having dementia can make many everyday tasks increasingly problematic. People do lots of things automatically without thinking about it,” says Alzheimer’s Europe. “With dementia, simple tasks like getting dressed, having a bath or making a cup of coffee gradually become problematic it is no longer obvious what to put on first it is difficult to switch from the shower unit to the bath tap the coffee machine is complicated to work out, etc. As these tasks seem so easy and obvious, it can be frustrating and embarrassing to mention it to other people. Consequently, many people with dementia struggle on, trying to hide their problems.”

You May Have Difficulty Reasoning Or Problem

“With any type of dementia, there will likely be noticeable decline in communication, learning, remembering, and problem solving,” says Help Guide. “These changes may occur quickly or very slowly over time. The progression and outcome vary, but are largely determined by the type of dementia and which area of the brain is affected.”

Whats The Difference Between Dementia With Lewy Bodies And Parkinsons

In dementia with Lewy bodies, dementia always appears first. There can also be changes in alertness as well as visual hallucinations. However, because of the presence of Lewy bodies throughout the entire brain, characteristics of this disease not only include cognitive characteristics, but also physical, sleep, and behavioral changes. As the disease progresses, the motor symptoms common to Parkinsons such as tremor, slowness, stiffness, and walking and balance problems will appear.

Behavioral And Mood Symptoms Of Lewy Body Dementia

Changes in behavior and mood are possible in LBD and may worsen as the persons thinking abilities decline. These changes may include:

• Apathy, or a lack of interest in normal daily activities or events and less social interaction
• Anxiety and related behaviors, such as asking the same questions over and over or being angry or fearful when a loved one is not present
• Agitation, or restlessness, and related behaviors, such as pacing, hand wringing, an inability to get settled, constant repeating of words or phrases, or irritability
• Delusions, or strongly held false beliefs or opinions not based on evidence. For example, a person may think his or her spouse is having an affair or that relatives long dead are still living.
• Paranoia, or an extreme, irrational distrust of others, such as suspicion that people are taking or hiding things

Whats The Difference Between Multiple System Atrophy And Parkinsons

Parkinsons and MSA both affect the movement control system and the involuntary autonomic control system and early symptoms can make a differential diagnosis a challenge. MSA, however, tends to progress faster than Parkinsons balance problems and a stooped posture happen earlier and get worse more quickly with MSA and autonomic functions such as blood pressure, heart rate, breathing, sweating, bladder function, and sexual problems are more severe in people with MSA.

Difficulty Finding The Right Words

Another early symptom of dementia is difficulty with communicating thoughts. A person with dementia may have a hard time explaining something or finding the right words to express themselves. They may also stop in the middle of a sentence and not know how to continue.

Having a conversation with a person who has dementia can be challenging, and it may take longer than usual for them to express their thoughts or feelings.

The Effects Of Alzheimers On The Brain

In people with Alzheimers disease, brain cells die and connections between brain cells may break down. One of the hallmark symptoms is abnormal protein deposits in the brain called plaques and tangles.

Plaques are dense clusters of protein that can block communication between neurons. Tangles are proteins that twist together that lead to the death of healthy brain cells.

In advanced Alzheimers, the brain shows significant shrinkage. Changes in the brain may occur a or more before symptoms start.

Its impossible to diagnose Alzheimers with complete accuracy while a person is alive. The diagnosis can only be confirmed when the brain is examined under a microscope during an autopsy. However, specialists can make the correct diagnosis up to 90 percent of the time.

The symptoms of Alzheimers and dementia can overlap, but there can be some differences.

Both conditions can cause:

• behavioral changes
• difficulty speaking, swallowing, or walking in advanced stages of the disease

Some types of dementia will share some of these symptoms, but they include or exclude other symptoms that can help make a differential diagnosis.

Lewy body dementia , for example, has many of the same later symptoms as Alzheimers. However, people with LBD but are more likely to experience initial symptoms such as visual hallucinations, difficulties with balance, and sleep disturbances.

You May Have Personality Changes

“People with dementia often act in ways that are very different from their ‘old self,’ and these changes can be hard for family and friends to deal with. Behavior changes for many reasons,” says the Weill Center for Neurosciences. “In dementia, it is usually because the person is losing neurons in parts of the brain. The behavior changes you see often depend on which part of the brain is losing cells.”

Types Of Lewy Body Dementia And Diagnosis

LBD refers to either of two related diagnoses dementia with Lewy bodies and Parkinson’s disease dementia. Both diagnoses have the same underlying changes in the brain and, over time, people with either diagnosis develop similar symptoms. The difference lies largely in the timing of cognitive and movement symptoms.

In DLB, cognitive symptoms develop within a year of movement symptoms. People with DLB have a decline in thinking ability that may look somewhat like Alzheimer’s disease. But over time, they also develop movement and other distinctive symptoms of LBD.

In Parkinson’s disease dementia, cognitive symptoms develop more than a year after the onset of movement symptoms . Parkinson’s disease dementia starts as a movement disorder, with symptoms such as slowed movement, muscle stiffness, tremor, and a shuffling walk. These symptoms are consistent with a diagnosis of Parkinson’s disease. Later on, cognitive symptoms of dementia and changes in mood and behavior may arise.

Not all people with Parkinson’s disease develop dementia, and it is difficult to predict who will. Many older people with Parkinson’s develop some degree of dementia.

Caregivers may be reluctant to talk about a person’s symptoms when that person is present. Ask to speak with the doctor privately if necessary. The more information a doctor has, the more accurate a diagnosis can be.

Tremors Are Just One Of Many Symptoms That May Indicate Parkinsons Disease

In addition to tremors, there are several other symptoms to look out for if you suspect PD. According to the Mayo Clinic, many patients experience slowed movement, rigid muscles, impaired balance, poor posture, and a decreased ability to perform unconscious movements, like swinging your arms while you walk. Additionally, PD patients often notice changes to their speech, including speaking more softly, speaking in monotone, developing a slur, or hesitating before speaking. Finally, some people with Parkinsons find that their handwriting changesit may become increasingly difficult to write, and your handwriting may become smaller over time.

Lewy Body Dementia Research

Many avenues of research are being explored to improve our understanding of LBD. Some researchers are working to identify the specific differences in the brain between the two types of LBD. Others are looking at the disease’s underlying biology, genetics, and environmental risk factors. Still other scientists are trying to identify biomarkers , improve screening tests to aid diagnosis, and research new treatments.

Scientists hope that new knowledge about LBD will one day lead to more effective treatments and even ways to cure and prevent the disorder. Until then, researchers need volunteers with and without LBD for clinical studies.

NIH and other groups help people learn about clinical trials and studies and find research opportunities near them. Visit the following websites for details:

Misplaced your keys again? Forgot the title of that movie you saw last night? How can you tell whether you’re just having a âsenior moment,” or if there’s a more serious health problem to consider? Current treatments available for dementia are more effective when the condition is caught in its early stages, so it’s important to know when a âsenior moment” might really be a sign that it’s time to see your doctor.

Pd Tremors Only Occur When Youre At Rest

Not all tremors are due to Parkinsonsmany have other underlying causes. One way to help distinguish between a PD tremor and something else is that those associated with Parkinsons are resting tremorsmeaning they only occur when that body part is otherwise inactive.

The tremor appears as a shaking movement when the muscles are relaxed and not being focused on taking action, explains the APDA. If your tremor continues despite intentional movement of that body part, theres likely another explanation. For this reason, many PD patients with a jaw, mouth, or tongue tremor manage this symptom by chewing gum throughout the day.

Treatment And Care For Lewy Body Dementia

While LBD currently cannot be prevented or cured, some symptoms may respond to treatment for a period of time. An LBD treatment plan may involve medications, physical and other types of therapy, and counseling. A plan to make any home safety updates and identify any equipment can make everyday tasks easier.

A skilled care team often can suggest ways to improve quality of life for both people with LBD and their caregivers.

Our Eyes May Provide Early Warning Signs Of Alzheimers And Parkinsons

Forget the soul it turns out the eyes may be the best window to the brain. Changes to the retina may foreshadow Alzheimers and Parkinsons diseases, and researchers say a picture of your eye could assess your future risk of neurodegenerative disease.

Pinched off from the brain during embryonic development, the retina contains layers of neurons that seem to experience neurodegenerative disease along with their cousins inside the skull. The key difference is that these retinal neurons, right against the jellylike vitreous of the eyeball, live and die where scientists can see them.

Early detection is sort of the holy grail, said Ron Petersen, director of Mayo Clinics Alzheimers Disease Research Center and the Mayo Clinic Study of Aging. By the time a patient complains of memory problems or tremors, the machinery of neurodegenerative disease has been at work probably for years or decades.

Experts liken it to a cancer that only manifests symptoms at Stage 3 or 4. When patients begin to feel neurodegenerative diseases impact on their daily life, its almost too late for treatment.

Catching the warning signs of neurodegenerative disease earlier could give patients more time to plan for the future whether thats making caregiving arrangements, spending more time with family or writing the Great American novel.

How Do I Prevent Falls From Common Hazards

• Floors: Remove all loose wires, cords, and throw rugs. Minimize clutter. Make sure rugs are anchored and smooth. Keep furniture in its usual place.
• Bathroom: Install grab bars and non-skid tape in the tub or shower. Use non-skid bath mats on the floor or install wall-to-wall carpeting.
• Lighting: Make sure halls, stairways, and entrances are well-lit. Install a night light in your bathroom or hallway and staircase. Turn lights on if you get up in the middle of the night. Make sure lamps or light switches are within reach of the bed if you have to get up during the night.
• Kitchen: Install non-skid rubber mats near the sink and stove. Clean spills immediately.
• Stairs: Make sure treads, rails, and rugs are secure. Install a rail on both sides of the stairs. If stairs are a threat, it might be helpful to arrange most of your activities on the lower level to reduce the number of times you must climb the stairs.
• Entrances and doorways: Install metal handles on the walls adjacent to the doorknobs of all doors to make it more secure as you travel through the doorway.
