Aggression Prevention Training for Individuals With Dementia and Their Caregivers: A Randomized Controlled Trial.

OBJECTIVE: International appeals call for interventions to prevent aggression and other behavioral problems in individuals with dementia (IWD). Aggression Prevention Training (APT), based on intervening in three contributors to development of aggression (IWD pain, IWD depression, and caregiver-IWD relationship problems) aims to reduce incidence of aggression in IWD over 1 year. DESIGN: Randomized, controlled trial. SETTING: Three clinics that assess, diagnose, and treat dementia. PARTICIPANTS: Two hundred twenty-eight caregiver-IWD dyads who screened positive for IWD pain, IWD depression, or caregiver-IWD relationship problems randomized to APT or Enhanced Usual Primary Care (EU-PC). INTERVENTION: APT, a skills-based intervention delivered over 3 months to address pain/depression/caregiver-IWD relationship issues. EU-PC included printed material on dementia and community resources; and eight brief, weekly support calls. MEASUREMENTS: The primary outcome was incidence of aggression over 1 year, determined by the Cohen Mansfield Agitation Inventory-Aggression Subscale. Secondary outcomes included pain, depression, caregiver-IWD relationship, caregiver burden, positive caregiving, behavior problems, and anxiety. RESULTS: Aggression incidence and secondary outcomes did not differ between groups. However, in those screening positive for IWD depression or caregiver-IWD relationship problems, those receiving EU-PC had significant increases in depression and significant decreases in quality of the caregiver-IWD relationship, whereas those receiving APT showed no changes in these outcomes over time. CONCLUSION: The cost to patients, family, and society of behavioral problems in IWD, along with modest efficacy of most pharmacologic and nonpharmacologic interventions, calls for more study of novel preventive approaches.

Peaceful Mind: an open trial of cognitive-behavioral therapy for anxiety in persons with dementia.

BACKGROUND: Anxiety has a high prevalence among individuals with dementia, and it has a significant negative impact on their functioning; yet intervention studies are lacking. We developed Peaceful Mind, a cognitive-behavioral intervention for persons with dementia. In this paper, we describe the intervention and results of an open trial evaluating the feasibility and utility of the intervention and assessment procedures. METHODS: Peaceful Mind is implemented over a period of three months in the participant's home with involvement of a caregiver or "collateral." Dyads are followed for an additional three months via telephone. An assortment of simplified skills is offered, including self-awareness, breathing, behavioral activation, calming thoughts, and sleep skills. RESULTS: Nine participants were enrolled, eight completed the three-month assessment, and seven completed the six-month assessment. Overall, participants and collaterals were satisfied with the intervention and reported that they benefited in terms of anxiety, depression, and collateral distress. CONCLUSIONS: A randomized controlled trial would help determine whether this promising new treatment has a statistically significant impact on anxiety in this population.

A controlled trial of aromatherapy for agitation in nursing home patients with dementia.

OBJECTIVES: Two controlled trials of aromatherapy to decrease agitation in persons with dementia have recently produced promising results. However, both studies combined the use of essential oils with massage. Thus, it is unclear if the effect of the aromatherapy intervention was the result of smelling or the cutaneous absorption of the oils. The purpose of this study was to determine whether smelling lavender oil decreases the frequency of agitated behaviors in patients with dementia. DESIGN: The study design was within-subjects ABCBA (A = lavender oil, B = thyme oil, C = unscented grapeseed oil): 4 weeks of baseline measurement, 2 weeks for each of the five treatment conditions (10-week total intervention time), and 2 weeks of postintervention measurement. Oil was placed every 3 hours on an absorbent fabric sachet pinned near the collarbone of each participant's shirt. SETTING: A long-term care facility specifically for persons with dementia. PARTICIPANTS: Seven agitated nursing home residents with advanced dementia. MEASUREMENTS: Agitation was assessed every 2 days using a modified Cohen-Mansfield Agitation Inventory. Olfactory functioning was assessed with structured olfactory identification and discrimination tasks, and with qualitative behavioral observation during those tasks. RESULTS: Split-middle analyses conducted separately for each patient revealed no treatment effects specific to lavender, no treatment effects nonspecific to pleasant smelling substances, and no treatment effects dependent on order of treatment administration. There were no differences between participants with more and less intact olfactory abilities. CONCLUSION: There is significant evidence in the neurologic and neuropsychologic literature that persons with dementia have impaired olfactory abilities. Concordant with this literature, this study found no support for the use of a purely olfactory form of aromatherapy to decrease agitation in severely demented patients. Cutaneous application of the essential oil may be necessary to achieve the effects reported in previous controlled studies.

Anxiety in dementia: a critical review.

Until recently, little attention has been paid to anxiety symptoms in dementia. However, anxiety is common in this population, and associated with poor outcome and quality of life. The current review examines the existing literature around three major themes: the definition of anxiety in dementia, the properties of available instruments for assessment, and the clinical characteristics of anxiety in this population. Defining anxiety in individuals with dementia is complicated by the overlap between symptoms of anxiety, depression and dementia, and by the influence of the source of information. Several instruments are available to assess anxiety in this population, including general neuropsychiatric instruments and two scales designed specifically for this purpose. The reliability of these instruments is acceptable, but their validity has not been sufficiently examined, and they may discriminate poorly between anxiety and depression. Anxiety may be higher in vascular dementia than in Alzheimer's Disease, and it decreases in the severe stages of dementia. It is associated with poor quality of life and behavioral disturbances, even after controlling for depression. Little is known, however, about its social and environmental correlates. Limitations of the existing literature and key directions for future research are discussed.
