Notas del editor
- DLB is responsible for 10-20 percent of all dementias, approximately 1.5 million Americans. May coexist in the presence of other dementias, e.g. vascular or AZD Prevalence increases with age – mean age at presentation is 75, slightly more men than women affected
- This presentation should make you more aware of some of the unique features of DLB. Of particular importance are issues of prognosis and treatment. This diagnosis is very difficult to make and often confused with AZD early in its course The longer the patient is under observation and the more “eyes on the patient” to gather information, the more accurate and helpful we can be.
- Round eosinophilic intra-cytoplasmic inclusion bodies Specific stains can be used to detect the deranged protein, alpha synuclein Can be found in brainstem areas as well as cortical areas and hippocampus Amyloid plaques similar to AZD can also be seen, but are not as numerous and AZD hallmark of neuro-fibrillary tangles are rare or non-existant
- Lewy Body Disease is a spectrum disorder. Dementia, MSA, Down Syndrome, and Parkinson’s all share the findings of neuronal destruction and Lewy body formation.
- Correct answers are memory loss, interference with function, and 2 or more cognitive areas involved to achieve the diagnosis under DSM 5 criteria. Also, absence of delirium and not explained by another mental disorder such as depression
- This case scenario probably indicates he has dementia. Agism may attribute some symptoms to “just getting older”, but these findings are more substantial than normal aging. New DSM5 also requires no evidence of delirium and not explained by another mental disorder, e.g. depression
- Lewy Body is suggested by symptoms as follows. A hallmark of DLB is the appearance early on of delusions and hallucinations which typically do not occur until late in AZD. Response to medications is also a marker for DLB.
- Here are the remarkable symptoms and let’s take a closer look at a few of them.
- Difficulty appears when there is a step approach to tasks, e.g. making a shopping list, going to the store, finding the items and checking out, then following a recipe. Visuospatial tasks are those that require eye-hand coordination such as copying a drawing or tracing a path with your finger
- Wake-sleep cycles are abnormal Can do a task one day and not the next
- “the baby” and “the phantom border” are two common delusions Hallucinations are sometimes comical to others, but seriously taken by the patient
- Combined with visuospatial dysfunction, this problem can make it hard to feed oneself. Can’t button buttons. Patient appears lethargic and slowed down. Extreme fall risk.
- Constipation, lacrimation, salivation, urinary incontinence or bladder paralysis can occur. Of particular concern is hypotension which when combined with motor dysfunction, makes falling a certainty.
- A diagnosis of Lewy Body dementia is made by carefully observing all the patients problems and tying the findings together. Key is continuity of care and observance over time span; with fluctuations of good days and bad, may never see it all come together at once such as with a single office visit. Keeping a symptom diary will help everyone involved.
- Share the same ICD code as a spectrum disorder. Are PD and DLB the same? Arbitrary taxonomy would say so.
- Especially analgesics, psychotropics, sedative hypnotics, and anticholinergics. Haldol is the most pronounced of these.
- This is an approach to understanding and managing behavioral disturbances of which there will be many. Always need to rule out physical disease such as infection, silent MI, etc. Systematically assess, then try reducing number or dose of some of the medications. Look for new things added to the regimen by someone else or OTC. If control needed, avoid long-acting benzodiazepines and haldol. Neuroleptic, malignant hyperthermia syndrome
- Because LBD wasn’t clinical defined until 1996, research is lagging behind diseases like Alzheimer’s and Parkinson’s. While there isn’t data available yet on racial and socioeconomic disparities in DLB, it may be useful to look at other Lewy body disorders like Parkinson’s disease for clues. Possible causes of disparities in PD: Patient attitudes on when to seek treatment at specialized center, problems in diagnosis, access to care, physician referrals
- This is the same question we asked at the start of this section of the presentation. Now having heard the symptoms, let’s ask it again. Usually an “AH-HAH” moment occurs here.
- LBD is considered a very treatable dementia, as many of its symptoms CAN be ameliorated to some degree with treatment. So comprehensive treatment of all of LBD symptoms is important, as is a focus on palliative care. Managing symptoms like insomnia and constipation can improve the quality of life for both the person with LBD and their primary caregiver. In addition to medications, non-pharmacological interventions are very important to quality of life. Physical therapists can help with movement problems through cardiovascular, strengthening, and flexibility exercises, as well as gait training and general physical fitness programs. Speech therapists may help with low voice volume and voice projection, poor speaking ability, and swallowing difficulties. Occupational therapists help identify ways to more easily carry out everyday activities, such as eating and bathing, to promote independence. Music or expressive arts therapists may provide meaningful activities that can reduce anxiety and improve well-being. Mental health counselors can help people with LBD and their families learn how to manage difficult emotions and behaviors and plan for the future.
- Something that many people don’t appreciate is how heavily LBD can impact the primary caregiver. It’s known that Alzheimer’s caregivers are prone to isolation and depression, have a higher risk of medical illnesses and feelings of guilt. LBDA did a survey of 962 LBD caregivers to understand how the disease affects them LBD caregivers report medium to high levels of burden ¾’s fear of the future for their loved one Over half feel stress between caring for their loved one and their personal responsibilities And half feel uncertainty about what to do as a caregiver 40% report feeling very isolated because nobody knows about LBD ¼ feel that no one understood what they are going through Spouses reported total greater burden than nonspouses, which is understandable. They are older and more likely to live alone with the person with LBD. Caregiver burden in LBD is associated with the presence of any cognitive, behavioral or affective symptom. Strongest associations in total caregiver burden were patient disturbances in mood and sleep Interestingly, when we asked them “Have you had to deal with a crisis situation with the person with LBD in the past year, 64% said yes. ¾ of those who had a crisis included a trip to the emergency room Other emergencies required EMS or law enforcement Only 12% required inpatient psychiatric care and another 5% sought help from outpatient mental health services
- LBD creates a very challenging set of caregiving demands from early in the disease and it can burn caregivers out early due to its unpredictability. But beyond that, the low public awareness of LBD brings its own emotional toll on families, who have to explain what LBD is to every person they meet, including many of their healthcare providers. Look for warning signs Withdrawal from family and friends Feeling blue or increasingly sad Changes in sleep patterns Changes in appetite and/or weight Getting sick more often Emotional and physical exhaustion Increased irritability
- While the subjective burden they experience is high, their use of community resources is rather low. 38% reported they received no help at all and only 30% were satisfied with the help they were getting. Less than half used adult day programs, transportation or meal services. Only 29% used paid care in the home and 21% used adult day services. Less than a 1/3rd attend support groups and only A new study by Steve Zarit and colleagues suggests that dementia caregivers who regular use adult day care services at least twice a week actually see an increase in a beneficial stress hormone. This hormone is known to be protective against the physiological damaging effects of stressor exposure and may reduce risks of illness. Using adult day services may help reduce depletion of this beneficial stress hormone (DHEA-S) and allow the body to mount a protective and restorative response to the physiological demands of caregiving.
- Caregiving is more than just the physical care of a person with LBD. It’s good to help them find the best quality of life possible. Stay focused on them as an individual with emotional and spiritual needs, not just medical needs. Remember to keep your sense of humor and understand that there are going to be limitations that have to be accepted. Because people with LBD have a reduced level of attention and alertness, keep the stimulation low to moderate. It will help them not get exhausted from the stimuli. Take instructions one step at a time. As the disease progresses, offer them a choice of 2 things and then later, simple yes or no questions. Keep their daily routine relatively stable. Their memory may be relatively good, compared to a person with Alzheimer’s. Knowing what to expect can help to reduce anxiety and resistance to care. Delusions and hallucinations are common in LBD, so listen to what they are saying and respond to the emotions they are expressing. You can provide a lot of emotional comfort without having to tell them they are wrong or having a hallucination. Don’t forget to try redirecting them to other topics or activities as well. LBD is never the same two days in a row. Flexibility is the caregiver’s best friend. Any sudden changes are likely not progression of the disease, but signs of an illness, pain or exhaustion.
- LBD is the most misdiagnosed form of dementia. If you or a family suspect LBD, it’s important to seek a second opinion. LBD expertise can often be found at dementia clinics at university hospitals. Encourage family caregivers to become knowledgeable about LBD symptoms and treatments. They are often the front line protection between the person with LBD and traditional antipsychotics, especially in a hospital setting. Tell LBD families they can connect with others affected by LBD through support groups or online communities. Because LBD is so highly under-diagnosed, they may not personally know anyone else who has been touched by LBD. They find a tremendous amount of solace and support when they realize they are not alone. Remember that LBD is a heavy load for family caregivers. Caregivers should be viewed as your second patient and should be screened for caregiver burnout. They need someone else to help them objectively look at their options. I’ll say this from personal experience, as my father had LBD. Many times caregivers think there is only one good caregiving choice, when the truth is that there are several alternatives that we simply refuse to consider for our own personal reasons. But when we get desperate, those alternatives start to look pretty good. It bears saying that if a caregiver is so exhausted that they are sick, depressed, or, and it’s sad to say, but it does happen, suicidal, they cannot do anything for the person they love and are providing care for. Use these tips to help them find ways to balance their caregiving responsibilities with their own physical, emotional and spiritual needs.
- Help is available from the Lewy Body Dementia Association. Our Family Services are designed to help alleviate those feelings of isolation, by putting caregivers directly in touch with other caregivers. Many of our volunteers were former LBD caregivers, so they really understand.
- We have a many educational resources on our website, but I’d like to highlight two of our newest ones. The Diagnostic Symptoms Checklist is a free resource that can be downloaded and printed by families and professionals. It’s a list of key LBD symptoms that are part of the diagnostic process. There are lots of other symptoms, but they are more supportive and are not diagnostic in and of themselves. We also created a comprehensive symptom checklist to make it easier to identify, report and hopefully treat symptoms related to LBD. This new booklet from the National Institute on Aging was a collaboration between LBDA, the University of California, San Diego, and the National Institutes of Health. You can read the booklet online at LBDA’s website. Print copies can be ordered for free from NIA’s the Alzheimer’s Disease Education and Referral Center (ADEAR).
