Trimipramine is a sedating tricyclic antidepressant which is not only effective in the treatment of depression but also in primary insomnia. In contrast to most other antidepressants, trimipramine does not affect rapid eye movement sleep. In a large sample of depressive outpatients (N = 3926), the effect of trimipramine on dream recall and dream emotions was studied. The effect of trimipramine...

Marijuana is the most widely used illicit substance among teenagers, yet little is known about the possible neural influence of heavy marijuana use during adolescence. We previously demonstrated an altered functional magnetic resonance imaging (fMRI) activity related to spatial working memory (SWM) among adolescents who were heavy users of after an average of 8 days of abstinence, but the...

The contribution of increased rapid eye movement (REM) pressure through repeated, mild, reduction of (REM) sleep to remission from untreated depression was studied over a 5-month period in 20 depressed and 10 control volunteers. Sixty percent of the depressed subjects were in remission at the end of the study. Sixty-four percent of the variance in remission could be accounted for by four...

Fifteen 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy') users who did not have other drug dependencies or prolonged alcohol abuse and 15 control subjects were studied. All the subjects were exposed to the same psychosocial stressor (Stroop Color-Word Interference Task, public speaking and mental arithmetic in front of an audience) 3 weeks after MDMA discontinuation. Plasma concentrations of...

Hallucinations are perceptual phenomena involved in many fields of pathology. Although clinically widely explored, studies in the general population of these phenomena are scant. This issue was investigated using representative samples of the non-institutionalized general population of the United Kingdom, Germany and Italy aged 15 years or over (N=13,057). These surveys were conducted by...

To test that REM sleep and/or dreaming aid in the overnight regulation of negative mood, 60 student subjects, selected to have no current or past episodes of depression, were tested with the Profile of Mood States (POMS) before and after two nights of laboratory sleep. There was a significant overnight effect of sleep on the Depression scale (Dep) both on a sleep-through night and a night of...

Hallucinogen persisting perceptual disorder (HPPD) may follow the ingestion of LSD or other hallucinogens in a subset of users. It is characterized by chronic, intermittent or constant visual hallucinations of many sorts persisting beyond the period of acute drug effects. We studied 44 LSD-induced HPPD subjects and 88 matched controls to search for spectral and evoked potential differences...

Despite the widespread abuse of marijuana, knowledge about its effects in the human brain is limited. Brain glucose metabolism with and without delta 9 tetrahydrocannabinol (THC) (main psychoactive component of marijuana) was evaluated in eight normal subjects and eight chronic marijuana abusers with positron emission tomography. At baseline, marijuana abusers showed lower relative cerebellar...

We previously reported that violent offenders with paranoid symptoms or whose violent actions had been directed against family members had higher urinary levels of bufotenin than other violent offenders. In the present study, patients were evaluated with the Karolinska Scales of Personality (KSP), and urinary levels of bufotenin were determined by mass spectrometry. In drug-free patients...

One way to study dream function is to use dream content as an independent variable. Erroneous or inconstant definition of the dream content, however, would undermine its use as a predictor. This study describes a dream interview technique that allows assessment and control of the distorting effect from using, in addition to a single report of manifest content, associative dream content and...

Dreams reported from laboratory awakening of stably married women differed from those of women undergoing divorce: The former dreamed of the experiment; the latter had more threat themes. Those coping well during the divorce had more positive motives in the last dream than those who were depressed. Dreams of the nondepressed divorcées increased in anxiety from first to last dream report,...

Ninety-five patients hospitalized for acute psychosis were reviewed with respect to hallucinogen use and family history of mental illness. Sixty-three percent of admissions had used hallucinogens to some degree within 3 years of the index admission. Drug users were predominantly male, although no age or diagnostic differences with the nondrug group were found. The incidence of hospitalized...
