Dementia is an illness that causes memory problems; changes in behavior; and difficulty with thinking, making decisions, and carrying out daily activities. Many people with dementia also have anxiety, and yet very little is known about effective treatment strategies for anxiety in this population. Cognitive behavioral therapy (CBT) is a type of psychotherapy that is commonly used to treat anxiety. CBT involves teaching patients skills to help them manage their anxiety, such as relaxation, changing their thoughts, and problem-solving. This study will evaluate the effectiveness of CBT in treating anxiety in older adults with dementia. In addition, the study will determine the effect of the treatment on patients' families and friends, and how families and friends may be able to help patients manage their anxiety. All study participants will name a family member or friend who will also participate in the study.
All participants in this study will answer a preliminary set of questions about anxiety and memory and will then complete a number of activities that involve learning and memory. These evaluations will take approximately 45 minutes. Participants who are selected to continue in the study will answer a second set of questions about mood, memory, concentration, and how they are doing in certain areas of life. These interview questions will take place during 2 sessions and will last a total of approximately 3 hours. Participants will then be randomly assigned to receive either enhanced usual care or 8 to 10 sessions of CBT over a period of 10 to 12 weeks. Each CBT session will last about 1 hour and will include meeting with a study staff member to discuss anxiety and how to cope with it. Participants will also complete practice activities at home for about 20 minutes per day. Enhanced usual care will consist of regular ongoing care from healthcare providers and biweekly phone calls for 3 months, followed by monthly phone calls for the next 3 months. Some of the pretreatment questions will be asked again immediately after the treatment period has been completed and again 3 months later for all participants.
