Pattern of Depressive Symptoms in Parkinson's Disease
ABSTRACT Depressive symptoms are common in Parkinson's disease (PD); however, it is unclear whether there are specific depressive symptom patterns in patients with PD and comorbid depression (dPD).
The goal of this study is to examine the frequency and correlates of specific depressive symptoms in PD.
A sample of 158 individuals with PD completed the self-rated Harvard Department of Psychiatry/National Depression Screening Day Scale (HANDS). By multiple-regression analysis, the authors examined the association between HANDS total and subscale scores and various demographic variables.
The frequency of depression was 37% (N=58). Patients with a history of depression before PD had significantly more serious depression than those who had no such history. Of those who were more depressed, the most common symptoms of depression endorsed were low energy, difficulty with concentration/making decisions, feeling blue, feeling hopeless, and having poor sleep.
There is a relatively high prevalence of dPD. Items on the HANDS that discriminated best between depressed and nondepressed subjects with PD included feeling blue, feeling hopeless, feeling worthless, lack of interest, and self-blame. It remains to be defined whether dPD should be understood primarily as a psychological reaction to a physical disability or perceived impending one, or as a direct expression of the neuropathology of PD.

- "As indicated on the CONSORT diagram (Figure 1), during check-in at the Cancer Institute, patients were approached by clinical psychology doctoral students and given the opportunity to complete the Harvard National Depression Screening scale (HANDS; Baer et al., 2000), a 10-item measure assessing core symptoms of major depression (DSM-IV; APA, 1994). The HANDS has been used with cancer patients (Hopko et al., 2008) and other samples of depressed medical patients (Farabaugh et al., 2009; Gonzalez et al., 2007). The HANDS has a score range of 0-30, with a cutpoint of 9 or greater having diagnostic sensitivity of 95% (Baer et al., 2000). "
ABSTRACT: Major depression is the most common psychiatric disorder among breast cancer patients and is associated with substantial impairment. Although some research has explored the utility of psychotherapy with breast cancer patients, only 2 small trials have investigated the potential benefits of behavior therapy among patients with well-diagnosed depression. In a primarily Caucasian, well-educated sample of women (age = 55.4 years, SD = 11.9) diagnosed with breast cancer and major depression (n = 80), this study was a randomized clinical trial testing the efficacy of 8 sessions of behavioral activation treatment for depression (BATD) compared to problem-solving therapy. Primary outcome measures assessed depression, environmental reward, anxiety, quality of life, social support, and medical outcomes. Across both treatments, results revealed strong treatment integrity, excellent patient satisfaction with treatment protocols, and low patient attrition (19%). Intent-to-treat analyses suggested both treatments were efficacious, with both evidencing significant pre-post treatment gains across all outcome measures. Across both treatments, gains were associated with strong effect sizes, and based on response and remission criteria, a reliable change index, and numbers-needed-to-treat analyses, approximately ¾ of patients exhibited clinically significant improvement. No significant group differences were found at posttreatment. Treatment gains were maintained at 12-month follow-up, with some support for stronger maintenance of gains in the BATD group. BATD and problem-solving interventions represent practical interventions that may improve psychological outcomes and quality of life among depressed breast cancer patients. Study limitations and future research directions are discussed.Journal of Consulting and Clinical Psychology 12/2011; 79(6):834-49. DOI:10.1037/a0025450 · 4.85 Impact Factor

ABSTRACT: This paper describes requirements for a user interface for a tele-machining system with operational environment transmission capability. The necessity of transmitting information concerning the operational environment requires a method for transformation of multi-axis force information to visual and auditory information. Methods for predictive display of geometrical information and auditory information to compensate for transmission time delays are also described. For tactile information presentation, an eccentric weight was used to generate vibration, whose frequency was controlled according to an index which represents machining state. Hardware and software construction suitable for multi-operator and multi-machine systems is also discussedRobot and Human Communication, 1995.

ABSTRACT: Parkinson's disease (PD) is a major neurodegenerative disorder that is usually considered in terms of midbrain and basal ganglia dysfunction. Regarding PD instead as a disconnection syndrome may prove beneficial to understanding aspects of cognition, perception, and other neuropsychological domains in the disease. PD is usually of unilateral onset, providing evidence of intrahemispheric dissociations and an imbalance in the usual relative strengths of the right and left hemispheres. Hence, in order to appreciate the neuropsychology of PD, it is important to apply to this disease our understanding of hemispheric lateralization effects and within-hemisphere circuitry from brainstem to higher-order association cortex. The focus of this review is on the relevance of PD-related disconnections among subcortical and cortical structures to cognition, perception, emotion, and associated brainstem-based domains such as sleep and mood disturbance. Besides providing information on disease characteristics, regarding PD as a disconnection syndrome allows us to more completely understand normal brain-behavior relations in general.Neuropsychology Review 04/2010; 20(2):191-208.
