The influence of psychotic symptoms on cannabis use has received little attention.AimsTo examine the influence of cannabis use on psychotic symptom relapse and the influence of psychotic symptom...

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...

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,...

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;...

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.,...

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...

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...

Introduction There have been many theories put forward to explain the not uncommon symptoms of depersonalization. They were aptly summarized by Ackner (1954) in the following way. There are theories which regard depersonalization as a symptom with an organic basis; there are theories which consider it a disturbance of a particular psychological function; there are analytic theories; and finally...

It is twenty years since the appearance of Stoll's paper: “Lysergic acid diethylamide, a hallucinatory agent of the ergot group” (23). In this he sought to reproduce in a group of subjects Hofmann's personal experiences of the drug, and so set the LSD snowball on its way. Some 1,500 papers must by now have been gathered to it; they deal with a greater range of uses than has been thought of for...

The view that depersonalization experiences can “be regarded as occupying a position somewhere between the delusional and the non-delusional” was first suggested by Ackner (1954) who gave as an example the depressive's experience of malaise. If this is accepted into the normal framework of experience it will be attributed to illness or fatigue. If it is accepted and organized into a delusional...

There have been relatively few studies concerning the occurrence of depersonalization phenomena in normal subjects. Roberts (1960) and Dixon (1963) studied college students and reported a high incidence of brief depersonalization experiences in their samples. The aim of the present study is to investigate the relationship between depersonalization, the conditions under which it occurred and a...

It has been shown that in depressive states (Sedman and Reed, 1963) and in schizophrenia (Sedman and Kenna, 1963) there is an association between the occurrence of depersonalization, a premorbid insecure personality and depression of mood.

The constellation of symptoms which is termed depersonalization is often as perplexing to the doctor as to the patient. It is more easily diagnosed than defined, and much of the controversy over its nosological position can be attributed to this vagueness of outline. Saperstein (1949) reviewed the historical development of the concept and concluded that the essential feature is the experience...

Numerous recent electroencephalographic studies have revealed the cyclical alternation of two distinct types of sleep (Dement and Kleitman, 1957a), which have been termed “fore-brain” and “hind-brain” sleep by Jouvet (1962). The former is accompanied by slow waves and spindles in the electroencephalogram (EEG) and the latter by a low-voltage, fairly fast EEG pattern; spasmodic, conjugate rapid...

Depersonalization has been so frequently reported in connection with incipient schizophrenia that some diagnosticians have regarded it as a pathognomonic sign of schizophrenia. More generally, however, it is regarded as a non-specific psychiatric syndrome since it has been reported in a variety of psychotic, neurotic and neurological disturbances (Ackner, 1954).

Lysergic acid diethylamide (LSD) has been used at Powick Hospital since 1952. During the early years of the treatment it became apparent that many of the dramatic psychic manifestations of the drug, including the vivid hallucinatory experiences, sensory hyperacuity, etc., were of no therapeutic value and that the chief use of the drug lay in its ability to bring into consciousness repressed...
