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 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)
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)
Numerous articles have been published investigating the incidence of and risk factors for delirium after cardiac surgery. Smith and Dimsdale reviewed the literature on postcardiotomy delirium in 1987 using a meta-analysis of 44 research studies. However, doubts about their methods and results caused the authors to re-examine the literature using these 44(More)
Hypotheses about the pathophysiology of delirium are speculative and largely based on animal research. According to the neurotransmitter hypothesis, decreased oxidative metabolism in the brain causes cerebral dysfunction due to abnormalities of various neurotransmitter systems. Reduced cholinergic function, excess release of dopamine, norepinephrine, and(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)
