The epidemiology and differential diagnosis of near-death experience.

This paper considers the generally consistent description of the common elements involved in near-death experiences (NDEs). It is suggested that the framework for studying a new psychiatric syndrome provides a context within which NDEs can be articulated both for research and for the practice of mental health professionals.

The belief in the transmigration of souls: psychotherapy of a Druze patient with severe anxiety reaction.

In this paper the culture-sensitive psychotherapy of a 19-year-old Druze patient with severe anxiety reaction is described. The patient explained his anxiety and his symptoms as stemming from violent death in his former life and subsequent transmigration. The therapists joined the patient's explanatory model and previous traditional healing, adding hypnotic suggestion which relieved the symptoms. The relationship of patient symptomatology to cultural background, multiple personality disorder, possession and dissociation is discussed. The strategic combination of culture-specific and modern psychiatric approaches is advocated in similar cases.

Depersonalisation/derealisation symptoms in vestibular disease.

BACKGROUND: Depersonalisation is a subjective experience of unreality and detachment from the self often accompanied by derealisation; the experience of the external world appearing to be strange or unreal. Feelings of unreality can be evoked by disorienting vestibular stimulation. OBJECTIVE: To identify the prevalence of depersonalisation/derealisation symptoms in patients with peripheral vestibular disease and experimentally to induce these symptoms by vestibular stimulation. METHODS: 121 healthy subjects and 50 patients with peripheral vestibular disease participated in the study. For comparison with the patients a subgroup of 50 age matched healthy subjects was delineated. All completed (1) an in-house health screening questionnaire; (2) the General Health Questionnaire (GHQ-12); (3) the 28-item depersonalisation/derealisation inventory of Cox and Swinson (2002). Experimental verification of "vestibular induced" depersonalisation/derealisation was assessed in 20 patients and 20 controls during caloric irrigation of the labyrinths. RESULTS: The frequency and severity of symptoms in vestibular patients was significantly higher than in controls. In controls the most common experiences were of "déjà vu" and "difficulty in concentrating/attending". In contrast, apart from dizziness, patients most frequently reported derealisation symptoms of "feel as if walking on shifting ground", "body feels strange/not being in control of self", and "feel 'spacey' or 'spaced out'". Items permitted discrimination between healthy subjects and vestibular patients in 92% of the cases. Apart from dizziness, caloric stimulation induced depersonalisation/derealisation symptoms which healthy subjects denied ever experiencing before, while patients reported that the symptoms were similar to those encountered during their disease. CONCLUSIONS: Depersonalisation/derealisation symptoms are both different in quality and more frequent under conditions of non-physiological vestibular stimulation. In vestibular disease, frequent experiences of derealisation may occur because distorted vestibular signals mismatch with the other sensory input to create an incoherent frame of spatial reference which makes the patient feel he or she is detached or separated from the world.

Separating depersonalisation and derealisation: the relevance of the "lesion method".

OBJECTIVES: Depersonalisation (DP) and derealisation (DR) are often met with in patients with a wide range of localisable neurological conditions. This suggests that the "lesion method" might be a valid approach to study the neurobiology of DP/DR. However, the fact that anxiety can trigger DP/DR makes it difficult to establish whether the presence of DP/DR in neurological patients is mainly determined by coexisting anxiety or by lesion location. To overcome this difficulty, we suggest the study of neurological phenomena, which although not considered as DP/DR, bear enough phenomenological resemblance with them as to warrant their use as models. METHODS: One patient with "visual hypoemotionality" and another with "hemiasomatognosia" are described in detail together with a selective literature review. RESULTS: Complaints of patients with visual hypoemotionality are indistinguishable from those of patients with "visual derealisation". There is also a phenomenological overlap between "asomatognosia" and the symptom of "body alienation", which is a central feature of depersonalisation. CONCLUSIONS: Phenomenological similarities between visual hypoemotionality and DR suggest that a disruption of the process by means of which perception becomes emotionally coloured may be an underlying mechanism in both conditions. Likewise, phenomenological overlaps with asomatognosia suggest that DP might result from parietal mechanisms disrupting the experience of body ownership and agency. These findings give validity to the notion that DP and DR may have distinct neurobiological mechanisms.

'Alice in Wonderland' syndrome as a precursor of depressive disorder.

A 54-year-old Japanese businessman who was found to exhibit the 'Alice in Wonderland' syndrome and went on to develop a depressive disorder is described. Lengthening and shortening of time experience continued intermittently for about 3 months, and metamorphopsia, distortion of body image, and the quick-motion phenomenon (alteration in time sense) persisted for almost 2 days without interruption. There were no abnormal physical findings. The authors review studies on 'Alice in Wonderland' syndrome and suggest that depressive illness may be a causal factor.

Visual imagery and depersonalisation.

Twenty-eight people diagnosed with depersonalisation disorder (DD) were assessed using self-report measures of imagery ability in relation to a range of symptoms and in comparison with age- and sex-matched controls. It was found that symptoms of depersonalisation as well as other dissociative symptoms and depressed mood correlated with impaired ability to generate visual images. This was particularly evident with images pertaining to the self and other people as opposed to objects. A subgroup of 10 patients was tested on a neuropsychological battery of visual perception tests and found to be unimpaired compared with normal controls and patients with obsessive compulsive disorder, despite subjective impairments in imagery and high symptom scores. The findings add further weight to the distinctions made between imagery and perceptual processes.

Why do people injure themselves?

The aim of this study was to evaluate a questionnaire for the assessment of immediate functions of self-injurious behavior (SIB). SIB is defined as deliberate injuries of the skin such as burning, cutting or beating. Suicidal attempts as well as self-injuries for aesthetic reasons were excluded. Immediate functions were collected from the literature as well as from statements of SIB sufferers. Finally, 154 questions with the response options 'right', 'wrong' and 'unknown' -- for phenomena people did not know -- were given to 120 persons with SIB aged 13-54 years. They were recruited from SIB-related homepages as well as from psychologists and psychiatrists in hospitals in Austria and Germany. Twelve factors were extracted via factor analysis (varimax rotation): 'self-punishment', 'coping with emotions', 'extreme rage', 'vitality', 'dissociation', 'changed perception', 'control over body', 'uniqueness', 'interaction', 'addiction', 'coping with sexuality' and 'expression of sexuality'. All items of each factor were analyzed and unsatisfactory ones excluded to devise a questionnaire as short as possible but with high expressiveness and good reliability. The remaining 107 items have a reliability of r = 0.9118 (Cronbach's alpha). Evaluation of this questionnaire is in progress.

Investigation of the syndrome of apotemnophilia and course of a cognitive-behavioural therapy.

BACKGROUND: The syndrome of apotemnophilia, body integrity or amputee identity disorder, is defined as the desire for amputation of a healthy limb, and may be accompanied by behaviour of pretending to be an amputee and sometimes, but not necessarily, by sexual arousal. SAMPLING AND METHODS: A case history is presented of a 35-year-old man who was referred because of his desire for amputation of his left leg, without sexual connotations. The course of a combined cognitive behavioural psychotherapy with SSRI treatment is described. RESULTS: Symptoms showed considerable similarity with obsessive-compulsive disorder, and some similarity with body dysmorphic disorder according to DSM-IV, but the core symptom seemed to be strongly connected with a sense of identity. Treatment with a selective serotonin re-uptake inhibitor decreased levels of distress only. The effects of cognitive restructuring of the psychotherapy were limited, whereas the behavioural elements substantially reduced the behaviour of pretending to be an amputee. CONCLUSIONS: The rare syndrome of apotemnophilia raises unresolved questions of classification. Psychotic disorders should be ruled out carefully. The model designed in the current cognitive behavioural approach may serve as a starting point for further development of intervention protocols for this rare disorder.
