Study of Social Behavior and Emotion in Frontotemporal Dementia, Alzheimer's Disease and Controls

October 27, 2011 updated by: Mario F. Mendez, University of California, Los Angeles
This study is designed to document the loss of sociomoral emotions (like empathy, guilt, and embarrassment) in patients with behavioral variant frontotemporal dementia. The loss of these emotions, which function as the motivators for social behavior, will manifest in specific interpersonal behaviors. These behaviors will correlate with regional changes in regional changes in medial frontal and anterior temporal lobes. These social and emotional changes will be compared with a young-onset Alzheimer's disease comparison group.

Detailed Description

Frontotemporal dementia (FTD) is a devastating disorder and one the most common neurodegenerative diseases in middle age. The most prominent early manifestations of bvFTD ("behavior variant" FTD) are not the memory and other cognitive deficits typical of Alzheimer's disease (AD) but, rather, disturbance in social or interpersonal behavior. A basic manifestation of this disorder is a disturbance in the emotions and motives that drive social and moral behavior. In fact, bvFTD is an incredible window to the neuroscience of social behavior. This study will help clarify the neurobiological substrates of sociomoral emotions and their associated clinical features. The findings of this proposal can have major implications for understanding the interaction between brain and social behavior and for designing future research on the basic mechanisms of social neuroscience. This research aims to document the loss of sociomoral emotions (SME) compared to primary emotions in patients with bvFTD vs. patients with AD and normal controls. We need to show that these findings are specific to bvFTD and not present in Alzheimer's disease or normal controls. The project consists of three integrated parts: 1) behavioral measures that include observations in naturalistic settings, behavioral experiments, and behavioral scales; 2) psychophysiological reactivity (i.e., measures of heart rate, blood pressure changes, galvanic skin response, facial electromyography, and facial temperature) to social and emotional stimuli; and 3) brain localization of changes in sociomoral emotions with magnetic resonance imaging technology.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Sampling Method

Non-Probability Sample

Study Population

  • Share personal information including feelings of distress about the subject's behavior or feelings of burden by caregiving responsibilities.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Psychophysiological Reactivity
Time Frame: within three months of study enrollment
We will evaluate autonomic (sympathetic and parasympathetic) nervous system reactivity to sociomoral vs. non-social stimuli using measures of heart rate (and heart rate variability), blood pressure (and baroreflex sensitivity), finger pulse volume, and skin conductance changes. Investigators present social and non-social pictures, videos, and written scenarios to all three groups while recording these psychophysiologic measures.
within three months of study enrollment
Behavioral Reports and Observations
Time Frame: within three months of study enrollment
This proposal will use methods of ethnography to classify the social behavior of bvFTD and AD patients and their caregivers in their homes and during research visits. Four social behavioral experiments or vignettes will be used to cross-validate the results of augmented participant observation. Behavioral scales will record differences between caregiver and patient assessments of behavior and further validate the results of the participant observation.
within three months of study enrollment
MRI Brain-Mapping
Time Frame: within three months of study enrollment
An MRI scan evaluated with state-of-the-art techniques will yield three dimensional maps of localized structural changes that reflect the regions involved in mediating social, moral, and emotional behaviors.
within three months of study enrollment
