BACKGROUND Some cases of acute coronary syndrome (ACS) may be triggered by emotional states such as anger, but it is not known if acute depressed mood can act as a trigger. METHODS 295 men and women with a verified ACS were studied. Depressed mood in the two hours before ACS symptom onset was compared with the same period 24 hours earlier (pair-matched(More)
Activation of the innate immune system is commonly accompanied by a set of behavioural, psychological and physiological changes known as 'sickness behaviour'. In animals, infection-related sickness symptoms are significantly increased by exposure to psychosocial stress, suggesting that psychological and immune stressors may operate through similar pathways(More)
The sleep-wake cycle in Parkinson's Disease (PD) is profoundly disrupted, but less is known about circadian rhythm in PD and its relationship to other important clinical features. This study compared rest-activity rhythms in healthy older adults and PD patients with and without hallucinations. Twenty-nine older adults and 50 PD patients (27 with(More)
OBJECTIVE Type-D or "distressed" personality and depression following admission for acute coronary syndrome (ACS) have been associated with poor clinical outcome. The biological pathways underpinning this relationship may include disruption of the hypothalamic-pituitary-adrenocortical (HPA) axis. We therefore assessed cortisol output in patients who had(More)
OBJECTIVE To test associations between heart rate variability (HRV), depressed mood, and positive affect in patients with suspected coronary artery disease (CAD). Depression is associated with impaired HRV post acute cardiac events, but evidence in patients with stable coronary artery disease (CAD) is inconsistent. METHODS Seventy-six patients (52 men, 24(More)
OBJECTIVE Evidence suggests that emotional stress can trigger acute coronary syndromes in patients with advanced coronary artery disease (CAD), although the mechanisms involved remain unclear. Hostility is associated with heightened reactivity to stress in healthy individuals, and with an elevated risk of adverse cardiac events in CAD patients. This study(More)
BACKGROUND Pre-hospital delays in patients experiencing acute coronary syndromes (ACS) remain unacceptably long. AIMS To examine simultaneously a wide range of clinical, sociodemographic and situational factors associated with total pre-hospital delay and its two components. METHODS Pre-hospital delay data were collected from 228 patients with ACS using(More)
Facial emotion recognition impairments have been reported in Huntington's disease (HD). However, the nature of the impairments across the spectrum of HD remains unclear. We report on emotion recognition data from 344 participants comprising premanifest HD (PreHD) and early HD patients, and controls. In a test of recognition of facial emotions, we examined(More)
