  • rating scales for Behavioral Symptoms in huntington s disease critique and recommendations
    Movement Disorders, 2016
    Co-Authors: Tiago A Mestre, Erik Van Duijn, Vitor Tumas, Annecatherine Bachoudlevi, Monica Busse, Karen E Anderson, Philipp Mahlknecht, Joaquim J. Ferreira, Aileen M Davis, C Sampaio
    Abstract:

    Behavioral Symptoms are an important feature of Huntington’s disease and contribute to impairment in quality of life. The Movement Disorder Society commissioned the assessment of the clinimetric properties of rating scales in Huntington’s disease in order to make recommendations regarding their use, following previously used standardized criteria. A systematic literature search was conducted to identify the scales used to assess Behavioral Symptoms in Huntington’s disease. For the purpose of this review, seven Behavioral domains were deemed significant in Huntington’s disease: irritability, anxiety, depression, apathy, obsessive-compulsive behaviors, psychosis and suicidal ideation. We included a total of 27 Behavioral rating scales, 19 of which were of a single Behavioral domain, and the remaining 8 scales included multiple Behavioral domains. Three rating scales were classified as “recommended” exclusively for screening purposes: the Irritability Scale for irritability, and the Beck Depression Inventory-II and the Hospital Anxiety and Depression Scale for depression. There were no “recommended” scales for other purposes such as diagnosis, severity or change in time or to treatment. The main challenges identified for assessment of Behavioral Symptoms in Huntington’s disease are the co-occurrence of multiple behavioural Symptoms, the particular features of a Behavioral Symptom in Huntington’s disease, as well as the need to address stage- and disease-specific features, including cognitive impairment and lack of insight. The committee concluded that there is a need to further validate currently available Behavioral rating scales in Huntington’s disease to address gaps in scale validation for specific Behavioral domains and purpose of use.

  • evidence for altered brain reactivity to norepinephrine in veterans with a history of traumatic stress
    Neurobiology of Stress, 2018
    Co-Authors: Rebecca C Hendrickson, Murray A Raskind, Steven P Millard, Carl Sikkema, Garth E Terry, Kathleen F Pagulayan, Elaine R Peskind
    Abstract:

    Abstract Background Increases in the quantity or impact of noradrenergic signaling have been implicated in the pathophysiology of posttraumatic stress disorder (PTSD). This increased signaling may result from increased norepinephrine (NE) release, from altered brain responses to NE, or from a combination of both factors. Here, we tested the hypothesis that Veterans reporting a history of trauma exposure would show an increased association between brain NE and mental health Symptoms commonly observed after trauma, as compared to Veterans who did not report a history of trauma exposure, consistent with the possibility of increased brain reactivity to NE after traumatic stress. Methods Using a convenience sample of 69 male Veterans with a history of combat-theater deployment, we examined the relationship between trauma-related mental health Symptoms and the concentration of NE in cerebrospinal fluid (CSF). CSF NE levels were measured by HPLC in CSF from morning lumbar puncture. Behavioral Symptoms associated with diagnoses of PTSD, depression, insomnia, or post-concussive syndrome (PCS), which together cover a wide variety of Symptoms associated with alterations in arousal systems, such as sleep, mood, concentration, and anxiety, were assessed via self-report (PTSD Checklist [PCL] for PTSD, Patient Health Questionnaire 9 [PHQ9] for depression, Pittsburgh Sleep Quality Index [PSQI] for sleep problems including insomnia, and NeuroBehavioral Symptom Inventory [NSI] for PCS) and structured clinical interview (Clinician-Administered PSTD Scale [CAPS]). Individuals meeting criterion A of the DSM-IV diagnostic criteria for PTSD were considered trauma-exposed. Linear regression models were used to quantify the association between CSF NE and Symptom intensity in participants with and without a history of trauma exposure, as well as in participants with a history of trauma exposure who were currently taking the noradrenergic receptor antagonist prazosin. Results Fifty-two Veterans met criteria for a history of trauma exposure; of these, 36 met criteria for PTSD. CSF NE levels were not significantly different in Veterans with a history of trauma compared to those without, nor in Veterans with PTSD as compared to those without. Veterans with a history of trauma and who were not using the medication prazosin demonstrated a significantly more positive correlation between CSF NE and Behavioral Symptom expression than Veterans who had not experienced traumatic stress. No relationship between CSF NE and Behavioral Symptom expression was found in Veterans who had experienced traumatic stress and were taking prazosin at the time of the assessments. Conclusions These results are consistent with increased central nervous system responsiveness to noradrenergic signaling in individuals with a history of traumatic exposure, raising the possibility that there may be long-lasting physiologic effects of trauma-exposure that exist independently of whether an individual meets criteria for PTSD at any given point in time. Exploration of the mechanism by which brain responsiveness to NE is modulated following trauma holds the possibility of finding new strategies for both preventing and treating PTSD.

  • The Communication Gap Between the Medical System and Community Resources for Dementia-Related Behavioral Symptom Management: Family Caregiver Perspectives.
    The Primary Care Companion To The Journal of Clinical Psychiatry, 2018
    Co-Authors: Glen L. Xiong, Haley Godwin, Linda Ziegahn, Teresa J. Filshtein, Laurel A. Beckett, Ladson Hinton
    Abstract:

    Objective: To examine family caregiver perspectives on cooperative communication surrounding pharmacologic and nonpharmacologic resources for the treatment of dementia-related Behavioral Symptoms. Methods: Personal narrative interviews were conducted by the primary investigator with 13 family caregivers from October 2014 to April 2015. The recorded interviews were then transcribed and coded. Models detailing the caregivers' resource utilization in regard to Behavioral Symptom management were produced for each participant and then summarized on the basis of recurring themes. Results: There is a significant gap in the coordination and communication between physician services and caregiver community resources to aid in the Behavioral management of family members with dementia. Physicians tend to rely on pharmacologic management independent of community resources and did not seem to be integrated or involved with recommendations from community resources. Conclusions: Better integration of caregiver resources is necessary to help caregivers in the management of dementia-related Behavioral Symptoms.
