Sleep paralysis among Cambodian refugees: association with PTSD diagnosis and severity.

Among Cambodian refugees attending a psychiatric clinic (n=100), 49% (49/100) had at least one episode of sleep paralysis (SP) in the previous 12 months. The annual and monthly SP prevalences were much higher in posttraumatic stress disorder (PTSD) than in non-PTSD patients. Among the PTSD patients, 65% (30/46) had monthly episodes of SP versus 14.85% (8/54) among non-PTSD patients (chi2[2, n=100]=26.78, P<.001). Moreover, patients with SP in the last month (n=30) versus those without SP had much higher PTSD severity scores. In the entire sample (n=100), the PTSD severity scores correlated significantly with the rate of SP in the last month. During SP, Cambodian refugees usually hallucinated an approaching figure (90%, 44/49). The rate of SP-associated and post-SP panic attacks was high, indicating the great distress caused by the phenomenon. SP seems to be a core aspect of the Cambodian refugee's response to trauma. When treating Cambodian refugees, and traumatized refugees in general, clinicians should assess for its presence.

Exploding head syndrome followed by sleep paralysis: a rare migraine aura.

A 26-year-old patient is described with a unique migraine aura. She described an 8-year history of episodes occurring 1 to 2 times yearly of exploding head syndrome followed by sleep paralysis followed by a migraine headache. She also had identical headaches without aura about once per week. Both aura symptoms, which may occur in the brainstem, resulted in activation of the trigeminovascular system through an unknown mechanism.

[Isolated sleep paralysis in patients with disorders due to anxiety crisis].

The relationship between isolated paralysis and panic disorder in adults is analyzed in this study. The patients included in this work presented anxiety disorder with agoraphobia and were compared with a group of normal controls. The percentage of patients with sleep paralysis was 40% significantly higher than those encountered in the control group (20%). The existence of this syndrome do not seem to modify the clinical manifestation or severity of panic disorder.

Spatial characteristics of hallucinations associated with sleep paralysis.

INTRODUCTION: Spatial properties of hallucinations have received relatively little systematic investigation. We present evidence from a web-based study of the spatial properties of a broad array of hallucinations associated with sleep paralysis. Predictions regarding spatial characteristics of hallucinations were based on proposed neurophysiological mechanisms underlying different types of hallucinations. METHOD: Distributions in three dimensions as well as distance and dispersion measures were assessed for 279 experient for two general categories of hallucinations: Intruder hallucinations--including presence, visual, and auditory hallucinations; and Vestibular-Motor (V-M) hallucinations--including floating, flying, illusory motor movements, out-of-body experiences (OBEs), and autoscopy. RESULTS: For all spatial measures, Confirmatory Factor Analysis revealed that Intruder and V-M hallucinations constituted distinctive factors. In addition, Intruder hallucinations were experienced as occurring close to, usually within a meter of, the experient, whereas V-M hallucinations involved excursions of considerable distance, often beyond the immediate environment. V-M hallucination distance was positively associated with vividness of V-M hallucinations, whereas Intruder hallucination distance was negatively correlated with theoretically related contact hallucinations (pressure, obstructed breathing, pain, choking, and touch). CONCLUSION: The differences in the spatial characteristics of Intruder and V-M hallucinations largely corroborated predictions based on the respective hypothesised neural substrates of a threat activated vigilance system and a bodily-self neuromatrix.

The relationship of isolated sleep paralysis and panic disorder to hypertension.

An hypothesis is proposed that there exists a subgroup of African-American hypertensive patients whose hypertension could have been prevented by the early detection and treatment of easily recognizable symptoms that signal the initiation of the pathophysiologic processes that lead to essential hypertension.A pilot study of 31 patients with elevated blood pressure revealed that 41.9 percent had isolated sleep paralysis, 35.5 percent had panic attacks, and 9.7 percent had panic disorder. These proposed hyperadrenergic phenomena may be related to the development of hypertension in certain individuals.

Panic disorder in African-Americans: symptomatology and isolated sleep paralysis.

While attention has been paid to the study of panic disorder (PD) with or without agoraphobia among Caucasians, surprisingly little empirical research within the United States has looked at the phenomenology of PD among minority groups. In this paper we present data we have collected and review other research on the phenomenology, social supports, and coping behavior among African-Americans with panic disorder. Our studies indicate that, in comparison to Caucasians, African-Americans with PD reported more intense fears of dying or going crazy, as well as higher levels of numbing and tingling in their extremities. African-Americans reported higher rates of comorbid post traumatic disorder and more depression. African-Americans also used somewhat different coping strategies (such as religiosity and counting one's blessings), less self-blame, and were somewhat more dissatisfied with social supports. The incidence of isolated sleep paralysis was, as per previous reports, higher in African-Americans. These findings, results of other research, and the implications for assessment and treatment are discussed within a semantic network analysis of panic (Hinton and Hinton 2002, this issue).
