BACKGROUND Asperger syndrome (AS) is a neurodevelopmental disorder belonging to autism spectrum disorders with prevalence rate of 0,35% in school-age children. It has been most extensively studied in childhood while there is scarcity of reports concerning adulthood of AS subjects despite the lifelong nature of this syndrome. In children with Asperger(More)
Previous functional connectivity studies have found both hypo- and hyper-connectivity in brains of individuals having autism spectrum disorder (ASD). Here we studied abnormalities in functional brain subnetworks in high-functioning individuals with ASD during free viewing of a movie containing social cues and interactions. Twenty-six subjects (13 with ASD)(More)
The effect of a single dose of 10 mg olanzapine on healthy volunteers of both sexes was examined using polysomnography and power spectral analysis. The structure and continuity of sleep were unaffected by olanzapine in both sexes. The increase in both actual sleep time and slow wave sleep in females correlated with the increase in theta power, while delta(More)
BACKGROUND An increased amount of deep sleep has been shown to be associated with antisocial personality disorder. This phenomenon has also been observed in a habitually violent female offender with schizophrenia and alcohol dependence. AIM To evaluate sleep patterns in this patient and compare them with those of healthy, pro-social women of similar age,(More)
Many symptoms of antisocial personality disorder have been proposed to be related to decreased daytime vigilance. To explore this hypothesis, quantitative analyses were conducted of the electroencephalographic (EEG) activity of drug-free and detoxified homicidal male offenders with antisocial personality disorder as the primary diagnosis. Subjects comprised(More)
Asperger syndrome (AS) is a neurodevelopmental disorder belonging to autism spectrum disorders. Both children and adults with AS have subjective impairment in the initiation and continuity of sleep, and studies using objective assessment are sparse. Twenty young AS adults with frequent complaints of low sleep quality were compared to 10 age-, gender- and(More)
The project Adult Dyslexia and Attention Deficit Disorder in Finland (Project DyAdd) compares adults (n = 119, 18-55 years) with dyslexia, attention-deficit/hyperactivity disorder (ADHD), dyslexia together with ADHD (comorbid), and healthy controls with neuropsychological, psychophysical, and biological methods. The focus of this article is on the Wechsler(More)
The aim of the present study was to characterize the subjective and objective sleep and sleep quality in habitually violent offenders with DSM-IV diagnosis of antisocial personality disorder using a sleep questionnaire, actigraphy, polysomnography and power spectral analysis. Subjects for the study were 19 drug-free males (mean age +/- SEM 30.7 +/- 2.58(More)
Two research traditions, the one on Asperger syndrome (AS) and the other on alexithymia, have produced similar findings independently of each other indicating a possible association between these two phenomena. Both conditions are also associated with impaired initiation and continuity of sleep. Twenty AS adults were compared with 10 healthy controls using(More)
BACKGROUND As pyromania is a rare diagnosis with questionable validity, we aimed to describe a forensic psychiatric population of arson recidivists. METHODS The medical records as well as the forensic psychiatric examination statements of 90 arson recidivists referred for pretrial psychiatric assessment in Helsinki University Hospital Department of(More)
