1/6. Acquired narcolepsy in an acromegalic patient who underwent pituitary irradiation.The authors report the case of a 60-year-old man with acromegaly, who developed narcolepsy 2 weeks after completing radiotherapy for a pituitary adenoma. cataplexy and sleepiness were predominant symptoms. Onset of narcolepsy is unusual at this age and the temporal relationship following radiotherapy suggests this treatment was implicated. His CSF hypocretin levels were normal, indicating other factors may be important in his narcolepsy.- - - - - - - - - - ranking = 1keywords = sleep (Clic here for more details about this article) |
2/6. Relevance of sleep paralysis and hypnic hallucinations to psychiatry.OBJECTIVE: To describe a patient who presented with psychopathology in the wake of sleep paralysis and hypnopompic hallucinations, and to discuss the importance of these phenomena to psychiatric diagnoses. methods: Case report. RESULTS: A 25-year-old black South African woman developed paranoid beliefs and a sad and anxious mood in the wake of her first experience of sleep paralysis and hypnic hallucinations. She had no history of other sleep-related events. Reassurance, explanation of the physiological basis of her experience, and a short course of low-dose diazepam were provided. Her mood and sleep improved promptly and she no longer held paranoid beliefs. She did not experience further episodes of sleep paralysis or hypnic hallucinations and improvement was sustained at 6 months. CONCLUSIONS: It pays to probe for the core experiences or events that patients may be explaining by devising "delusions". Acute, nocturnal-onset, first-time psychopathology warrants inquiry for sleep paralysis and hypnic hallucinations. Sleep-related side-effects of psychotropic medications need to be studied more closely.- - - - - - - - - - ranking = 10keywords = sleep (Clic here for more details about this article) |
3/6. 'The ghost pushes you down': sleep paralysis-type panic attacks in a Khmer refugee population.Among a psychiatric population of Cambodian refugees (N = 100), 42% had current--i.e. at least once in the last year--sleep paralysis (SP). Of those experiencing SP, 91% (38/42) had visual hallucinations of an approaching being, and 100% (42/42) had panic attacks. Among patients with post-traumatic stress disorder (PTSD; n = 45), 67% (30/45) had SP, whereas among those without PTSD, only 22.4% (11/45) had SP (chi2 = 20.4, p < .001). Of the patients with PTSD, 60% (27/45) had monthly episodes of SP. The Cambodian panic response to SP seems to be greatly heightened by elaborate cultural ideas--with SP generating concerns about physical status, 'good luck' status, 'bad luck' status, sorcery assault, and ghost assault--and by trauma associations to the figure seen in SP. Case vignettes illustrate cultural beliefs about, and trauma resonances of, SP. A model to explain the high rate of SP in this population is presented. SP is a core aspect of the Cambodian refugees response to trauma; when assessing Cambodian refugees, and traumatized refugees in general, clinicians should assess for its presence.- - - - - - - - - - ranking = 5keywords = sleep (Clic here for more details about this article) |
4/6. Cultural variation in the clinical presentation of sleep paralysis.sleep paralysis is one of the lesser-known and more benign forms of parasomnias. The primary or idiopathic form, also called isolated sleep paralysis, is illustrated by showing how patients from different cultures weave the phenomenology of sleep paralysis into their clinical narratives. Clinical case examples are presented of patients from guinea Bissau, the netherlands, morocco, and Surinam with different types of psychopathology, but all accompanied by sleep paralysis. Depending on the meaning given to and etiological interpretations of the sleep paralysis, which is largely culturally determined, patients react to the event in specific ways.- - - - - - - - - - ranking = 8keywords = sleep (Clic here for more details about this article) |
5/6. 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.- - - - - - - - - - ranking = 1keywords = sleep (Clic here for more details about this article) |
6/6. 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.- - - - - - - - - - ranking = 5keywords = sleep (Clic here for more details about this article) |
