Sleep structure in patients with logoneurosis

Abstract

Introduction: Logoneurosis is a temporo rhythmical disorder of speech organization that occurs because of convulsive muscle contractions of the phonatory apparatus. It affects about 5-8% of children, 1% of adults and it is Associated with high levels of social anxiety. During childhood, in patients with logoneurosis, there are observed sleep disorders: startles before falling asleep, a restless superficial sleep, many dreams and nightmares. The objective of the research is to study the features of sleep in patients with logoneurosis. Materials and Methods:We carried out a case-control study where were included eight patients with logo neurosis and another eight persons without any speech pathology. Patients and healthy individuals were assessed by using the Spielberger level of anxiety and Pittsburgh (PQSI) sleep quality rating questionnaires. In two patients with logo neurosis from the study group, was performed a cardiorespiratory polygraphy with a neuroport (GATES 7). Results: Sex distribution in groups resulted a significant prevalence of the logoneurosis 3/4 or 75% in males (6), as compared to 25% (2) in women. After a statistical analysis, we obtained the following results: patients with logoneurosis had an average of 41.6 points of personality anxiety, compared to only 31.5 points in the control group, which indicates a significant difference (p <0.05); the average score of Pittsburgh inventory in patients with logoneurosis was 6.37 compared to 3.37 points from those of the control group (p <0.05). Following the assessment by cardiorespiratory polygraphy with a neuroport, we obtained the following results: a prolonged sleep latency in both patients (31 and 37 minutes); a sleep efficiency of 71.9% and 87.3% (norm> 90%); in both patients was determined a significant growth of 38.37% and 16.09% (norm 5-10%) of N1 sleep phase on hypnogramme and a decreased N2 sleep phase durationfrom 39.52% and 35.22% (norm 40-50%); in one patient has been observed an increase of periodic limb movements number in sleep and somniloquy. Conclusion: Patients with logoneurosis have a higher level of personality anxiety and a very low quality of sleep compared to people from control group. Hypnogramme evaluation revealed a high sleep latency and sleep fragmentation.
