Abstract

Sleep-related Rhythmic Movement Disorder (SRMD) generally occurs during the neonatal period or early childhood. However, it has not yet been precisely defined despite various hypotheses with respect to its etiopathogenesis. These types of movements rarely continue during adulthood. SRMD, likely to be idiopathic, may develop due to secondary causes as well. In this study, we highlight adult-onset SRMD in a patient with the diagnosis of lung cancer.

Highlights

Sleep-related Rhythmic Movement Disorder (SRMD) is a disease characterized by stereotypical movements, i.e. in the way that the body wriggles back and forth or right and left; the head and the neck hits/bangs the pillow vertically or horizontally; and the limbs move right and left and back and forth, all of which are all observed at the time of falling asleep or during superficial non-rapid eye movement sleep
SRMD is a sleep-related rhythmic movement disorder which generally occurs during the neonatal period or early childhood
The fact that the mass lesion in the lung of our patient invaded the T3-T4 vertebrae, the possibility of radiculopathy, and a lesion in the posterior portion of the spinal cord are considered to be responsible for this clinical picture. The neurological symptoms, such as paraneoplastic causes, drug side-effects, brain metastases, and spinal cord stresses are frequently seen in cancer patients

Summary

Introduction

Sleep-related Rhythmic Movement Disorder (SRMD) is a disease characterized by stereotypical movements, i.e. in the way that the body wriggles back and forth or right and left; the head and the neck hits/bangs the pillow vertically or horizontally; and the limbs move right and left and back and forth, all of which are all observed at the time of falling asleep or during superficial non-rapid eye movement sleep. The movements in question infrequently continue during adulthood The incidence of this disorder is observed as 59% during the neonatal period, 33.5% when the baby is 18 months old and 5% around the age of 5; it is seen rarely during adulthood [2]. The progression of such movements during puberty and adulthood is usually suggested to have an association with mental retardation, autism or other major pathologies [3]. In the literature, there are some cases described among adults with normal intelligence [4]
