Lewy Body Dementia
held May 29, 2014
It is estimated that Parkinson’s disease dementia, a type of Lewy body dementia, affects up to two percent of those over 65 and that of the nearly one million Americans with Parkinson’s, 50-80% will experience the dementia associated with it (Alzheimer’s Association, 2013). Additionally, there is increasing evidence to suggest that mixed dementia, a combination of two or more types of dementia, is more prevalent than previously thought and that it under diagnosed (Stephan and Brayne, dementia public policy; world report). For these reasons it is important to provide sound, evidence-based training on the different types of dementias, including the origins, symptoms and best practice treatments. Therefore, this series, through virtual training and active learning, seeks to advance the training and workforce development goals of the Virginia Dementia State Plan.
The webinar series will include a pre-recorded 30-minute free lecture that briefly reviews types of dementia and three, live 60-minute free webinars on different types of dementia (Lewy body dementia, vascular and mixed dementias, and Parkinson’s disease dementia) and with a special emphasis on ethnic and racial minorities. This is the third live webinar in the series which will focus on the dementia with Lewy Bodies.
WHAT WILL YOU LEARN?
- Define Lewy body dementia
- Review characteristics of Lewy body dementia
- Review management of Lewy body dementia
- The webinar will review the causes, signs and symptoms, disease trajectory, treatment options, and best practices for caring for the individual with Lewy body dementia as well as their caregivers.
- The webinar will pay particular attention to ethnic and racial minorities as well as available supports for individuals.
- The presenter will provide a case scenario to the webinar attendees and participants will be encouraged to answer questions and provide suggestions for how to handle the case.
- Flashcards will be available to allow participants to test their knowledge before and after the webinar.

QUESTIONS and ANSWERS
We thank Dr. Driscoll and Ms. Taylor for the additional time taken to respond to these audience-posed questions.
Q: Aricept is effective with Lewy Bodies? I had learned that it is effective with AD but has no effect with Lewy Bodies, does not work.
Aricept is an cholinesterase inhibitor medication and works well for many of the cognitive symptoms of DLB. Though of little help for memory (true of AZD as well), it is especially helpful to control behavioral aggresiveness, delusions and hallucinations, and other neuropsychiatric symptoms (e.g. anxiety, aberrant motor behavior, apathy, and indifference). They do not work acutely and are rather a long term solution. Reference Galvin, J.E., et al, Current Issues in Lewy Body Dementia Diagnosis, Treatment, and Research on LBDA.org web site.
Q: How can you differentiate fluctuating symptoms from delirium?
Fluctuations of cognition and levels of alertness are sometimes difficult to differentiate from stroke or seizures, but are not associated with the acute onset and shorter duration of delirium. The fluctuations are pretty dramatic with hypersomnolence, periods of almost near normal cognition, and prolonged staring spells. Speech can be slurred. I have seen many patients become unresponsive with normal vital signs and stay that way for hours or even up to two days without taking food or water. Recovery can be equally dramatic.
Q: I wondered if haldol can ever safely be given in a smaller dose, like the valium.
If 50% of patients experience a severe or dramatic reaction to these drugs, that means that 50% do not. Unfortunately, there is no way to predict which patients will have a dangerous reaction, so why take a chance? SSRIs are good medications to trial for controlling anxiety and depression and would be a better first line choice than valium. The atypical antipsychotics are recommended for acute behavior control rather than Haldol. An ECG would be advised prior to initiation of the drug if time permits as the cardiotoxic effects are also worrisome.
Q: What is the prevalence of DLB between men and women?
Slightly more in men than women, but about equal with the ration approaching 1.
Q: My mother is 85 and has DLB. She has incontinence and is on detrol. You are recommending not taking this drug. What do you recommend to help incontinence?
Detrol has anticholinergic effects which decrease brain activity. If the patient is alreading taking it and experiencing no problems, continue and watch closely for any increase in delusions, hallucinations, confusion or agitation. A trial off the detrol may show improvement in cognitive symptoms. I always recommend bladder training and behavioral control over medications. Voiding diary, scheduled toileting, using superabsorbent diapers, etc.
Q: Many of the symptoms for LBD, particularly those related to the sleep problems as well as the problem with memory, and audio/visual hallucinations sounds a lot like PTSD symtomology. Furthermore the case scenario of Hal and one of the clients discussed who was a retired colonel are (assumed) veterans during time periods where knowledge of PTSD was a lot less common or there were less evidence based supportive therapies to address and treat PTSD. Is there a possiblity of a link between decades of untreated PTSD and LBD? Or rather, could it be more so that in the cases of the vetarans discussed, the LBD was really more so the ravages of decades of untreated PTSD, and the accompanying physiological impacts we know that prolonged, acute stress has on the brain?
One of the cases I reported was a Colonel in the Air Force. He was a number-cruncher, flew a desk not a plane, and never saw any combat action. I am certain he did not suffer from PTSD based on his history. The second veteran was in combat, but according to his family had made smooth readjustment after the war (Korean) and did not have problems until his dementia surfaced. PTSD is an over-looked condition and your comment reminds us to maintain vigilance for it.
Q: Please discuss if possible the bio-psychosocial assessment and treatment strategies for aggression, including not stopping medication regimens that have been shown to work. We see high relapse rates associated with NH’s stopping medications, resulting in relapse of violence….
Medications are not the only answer to behavior control. Factors that play a role in the disordered behavior need to be searched for and corrected. Excessive lighting, fear, daily routines like bathing, pain, a high level of stimulation, sleep loss, etc. all need to be addressed. Arguing, punishment, or trying to convince a patient their actions are wrong or need to change is fruitless. Redirecting and tasking (e.g. a small box of Legos or folding napkins) can be useful. Music therapy can be of help. Snoozalin therapy has shown some success as have the same behavioral therapies used on autistic children. When medications are needed, cholinesterase inhibitiors and atypical antipsychotics are preferred approaches.
Q: Are you aware of LB support groups in Virginia – specifically the Shenandoah Valley area?
There are currently two support groups in Virginia, one in Fairfax and one in Lynchburg. The details on those groups can be found at http://lbda.org/sptgroups/%2A/node?field_state_value_many_to_one%5B%5D=VA. There are also virtual communities for LBD caregivers which you can find here: http://lbda.org/content/virtual-groups. LBDA also provides volunteer training to anyone who wants to start a support group in their community. You can contact LaToysa Scaife-Rooks at firstname.lastname@example.org or start the volunteer orientation process by watching our short training online, found here: http://lbda.org/go/volunteer.
Q: what was the name of the study on Adult Day Services?
The study was called the Daily Stress and Health (DaSH) Study, by Steve Zarit, PhD, and collegues. LBDA published two articles in our e-newsletter about the findings of the study, which you can read here: http://lbda.org/content/new-study-shows-caregivers-benefit-adult-day-services and http://lbda.org/content/adult-day-service-boosts-beneficial-stress-hormone-caregivers.
