While conventional religious practice shows signs of decline, this does not necessarily imply a decline in religious belief.It comes as a surprise that psy chiatrists should be so reticent in their inquiry into this aspect of their patients' emotional and cognitive experience.Only 3% of a qualitative review of the total output of four major psychiatric journals between 1978-1982 contained a...

Autoscopy is defined here as a visual experience where the subject sees an image of him/herself in external space, viewed from within his/her own physical body. This paper reviews the literature both historically and conceptually, and includes a quantitative study of accumulated cases. Cases published since 1935 and meeting the above definition for autoscopy (n = 53) were included, together...

Background 3,4-methylenedioxymethamphetamine (MDMA or ‘Ecstasy’) has become one of the most widely used illicit substances in the UK. Little is known of the psychiatric morbidity which may be associated with its use. We have examined this association by collecting a series of psychiatric cases in which MDMA use was a prominent feature. Method Patients presenting between 1990 and 1992 with...

Data were analysed from 62 schizophrenic patients between 18 and 30 years of age, treated at the community mental health centres in Navarra, who had relapsed and then completed a one-year follow-up study. Factors influencing the course of illness during follow-up were: continuing cannabis consumption; previous cannabis intake; non-compliance with treatment; and stress.

Cannabis abuse is a major public health problem in The Gambia and other parts of West Africa, and the rise in the incidence of psychotic illness reflects the increased background use of cannabis by the local population. A case-control study was performed to determine the association between psychosis and cannabis abuse in The Gambia and the importance of other risk factors. Out of 234 patients...

The usual phenomena of cannabis intoxication include experiences which in a non-intoxicated state would be considered as psychiatric symptoms. These can be distinguished from adverse reactions to cannabis, the commonest of which is an acute anxiety state. Acute psychotic episodes can also follow ingestion of the drug but are infrequent. These can be classified as acute confusional states and...

In-patients with psychotic symptoms and cannabis-positive urine analysis were assessed by PSE within one week of admission and again at one and six months. Concurrently admitted psychotic patients with drug-free urine analysis were controls. At one week the two groups differed significantly on only five PSE items: changed perception, thought insertion, non-verbal auditory hallucinations,...

A review of the evidence shows that there is no convincing support for a separate clinical diagnosis of 'cannabis psychosis'. Cannabis can, however, produce brief acute organic reactions and, in moderate to heavy doses, psychotic episodes in clear consciousness. Ingestion in naive users or increasingly heavy use in habitual users can precipitate a schizophreniform episode. Heavy users may have...

A relatively normal 16-year-old Chinese woman with a six-month history of compulsive water drinking resulting in a comatose state is reported. The drinking was perpetuated by an enjoyable altered state of consciousness after ingestion of an average of 20 litres of water per day. Treatment by fluid restriction and, later, simple education was successful. The subjective dimension of an altered...

The psychopathology of acute organic psychosis was investigated by interviewing 74 patients using the Present State Examination (PSE). Their delusions, perceptual disturbance, thought disorder, and emotional disorder were categorised and then compared with those seen in 74 acute schizophrenics. In acute organic psychosis there was a particular pattern to the delusions, perceptual disturbance,...

Summary Forty-six users of the hallucinogen lysergic acid diethylamide were compared with 31 controls on a test of colour discrimination an average of two years after their last exposure to the drug. Controls performed better than users, and LSD users without flashbacks performed better than users with flashbacks. An analysis of variance between the three groups was significant at P <0.001....

The excretion of N,N,-dimethyltryptamine (DMT) has been measured in longitudinal studies of five patients with schizophrenic illnesses and in four patients with rapidly or slowly cycling manic-depressive illness. The excretion of DMT was frequently raised in patients when they were psychotic but was usually normal when they had recovered. However, rapid changes in the severity of illness or...

SummaryThe symptoms of schizophrenia can be interpreted as the result of a defect in the mechanism that controls and limits the contents of consciousness. This defect can be understood as excessive self-awareness. Normally most of the complex information processing which is continuously required by even simple acts of perception, language and thought goes on below the level of awareness;...

Summary The use for hallucinogenic purposes of an indigenous mushroom, Psilocybe semilanceata indigenous to Britain is reported in three patients. Typical psychedelic, transient psychotic and more prolonged schizophrenia-like states were seen, with sympathomimetic signs noted in two cases, in one being prolonged. Enquiry about such mushroom abuse should be considered in individuals presenting...

Fifty persons who had all been heavy cannabis users for a long time were given psychological tests measuring psychomotor, perceptual and other variables. Half of these persons were "Charas" smokers, half "Bhang" drinkers. The duration of cannabis use was 4--10 years, with an average daily dose of 150 mg tetrahydrocannabinol. A matched control group of twenty-five persons were given the same...

The incidence and quantities of dimethyltryptamine and O-methylbufotenine were studied in the cerebrospinal fluid of patients suffering acute schizophrenic illnesses and in surgical and neurological control groups. Some schizophrenic patients have higher levels of both amines than do controls, though the differences in distribution did not reach statistical significance in the sample studied....

While the beneficial effect of lysergic acid diethylamide (LSD) in the treatment of carefully selected patients as an adjunct to psychotherapy has been amply reported (Robinson et al. , 1963), concern has been expressed regarding the damage to chromosomes in those taking the drug.

Almost all sleep-promoting drugs distort the natural pattern of sleep by suppressing rapid eye movement (REM) sleep, and cause a rebound to above-normal values on withdrawal which typically lasts about six weeks (Oswald, 1968, 1969). Furthermore, barbiturates reduce the number of eye movementsper unit timein REM sleep (Oswaldet al., 1963; Baekeland, 1967; Lesteret al., 1968; Feinberget al.,...

The LSD and schizophrenic experiences are similar in more ways than they are different. The states are phenomenologically similar, but the similarity is contaminated by the fact that no significant differences exist between these two groups and the control group on several measures, if the phenomena in question are regarded as isolated. Significant differences exist between the LSD and...

Hypnagogic hallucinations are well established in text books of psychiatry, as also are hypnopompic hallucinations. Hypnagogic hallucinations are those which occur as the subject falls asleep and prevent him falling into a sound sleep, whereas hypnopompic hallucinations occur when the subject is waking up. Since by definition hypnagogic hallucinations actually waken the subject, the distinction...

It is well recognized that LSD (lysergide) can give serious adverse reactions, including suicide and prolonged psychosis; Smart and Bateman (1967) have reviewed the subject thoroughly. However, examples reported refer largely to cases where the LSD was self-administered. Medical case reports usually cover small case numbers, and publication may be determined by high adverse reaction rates....

The complaints, ‘I am a stranger to myself; I am unreal’, are manifestations of depersonalization which have been noted frequently by clinicians. Depersonalization has been reported in epilepsy, after drug ingestion, encephalitis, hysteria, manic depression, and schizophrenia, as well as in various neurotic patients. It has also been noted in normals, but usually after emotional shock or...
