OBJECTIVE To investigate the prevalences of formal DSM-IV diagnoses in pre-motor- symptomatic and motor-symptomatic mutation carriers at different stages of Huntington's disease compared to a control group of first-degree noncarrier relatives and the general population. METHOD Between May 2004 and August 2006, 154 verified mutation carriers and 56(More)
BACKGROUND Previous studies indicate increased prevalences of suicidal ideation, suicide attempts, and completed suicide in Huntington's disease (HD) compared with the general population. This study investigates correlates and predictors of suicidal ideation in HD. METHODS The study cohort consisted of 2106 HD mutation carriers, all participating in the(More)
OBJECTIVE Suicidal behavior has been associated with reduced central serotonergic function. Because selective serotonin reuptake inhibitors (SSRIs) enhance serotonergic function, the authors studied the efficacy of an SSRI, paroxetine, in the prevention of recurrent suicidal behavior. METHOD They conducted a 1-year double-blind study comparing paroxetine(More)
BACKGROUND The aim of the present study was to examine the relationship between suicidal behavior and impulsiveness, and more generally borderline personality disorder on the one hand, and platelet indicators of central serotonergic function on the other. METHODS After a suicide attempt platelet serotonergic measures were obtained from 144 patients with(More)
OBJECTIVE To investigate behavioural problems in Huntington's disease (HD). METHOD In 152 HD mutation carriers and a control group of 56 noncarriers at initial 50% risk, the Dutch version of the Problem Behaviours Assessment (PBA) was administered. Mutation carriers were divided into three groups according to the motor section of the Unified Huntington's(More)
BACKGROUND The majority of Huntington's disease (HD) mutation carriers experience some psychopathology during their lifetime, varying from irritability to psychosis, but prevalences of particular symptoms vary widely due to diverse study populations in different stages of HD and the use of different assessment methods. METHODS The study population(More)
Antidepressant effects of mirtazapine and imipramine were compared in a randomized, double blind, fixed blood-levels study with in-patients in a single centre. Patients with a DSM-III-R diagnosis of major depression and a Hamilton (17-item) score of > or = 18 were selected. After a drug-free and a placebo-washout period of 7 days in total, 107 patients(More)
Besides chorea, hypokinesia is an important motor disturbance in Huntington's disease (HD) but its clinical, neuropsychiatric, and cognitive functioning correlates are largely unknown. This cross-sectional study investigates correlates of hypokinesia in HD and its effect on global functioning. Among 150 HD gene carriers, 96 patients were clinically motor(More)
To distinguish state- from trait-dependent associations between serotonergic function and suicidal behavior, platelet serotonergic measures were repeatedly measured, during a 1-year follow-up, in 106 patients who had recently attempted suicide for at least a second time. A major DSM-III-R axis I diagnosis or use of antidepressants were reasons for(More)
Incidence of and preoperative predictors for postoperative delirium were studied in 296 patients (age 26-83 years, mean age 63 years) undergoing elective cardiac surgery. Delirium occurred in 40 (13.5%) patients. Predictors included old age, low level of albumin, poor physical condition, use of nifedipine, and a high ratio of the amino acids phenylalanine(More)
