Cerebral Palsy: Motor Types, Gross Motor Function and Associated Disorders
Objectives: Cerebral palsy (CP) describes a group of disorders in the development of movement and posture in the developing brain. The main aim of this study was to determine the distribution of motor impairment and associated disorders in a population of children with CP. Methods: This study was carried out in 2011 during three months, on 200 CP children. Multiple sources of ascertainment w...
متن کاملAcquired Ocular Motility Disorders and Nystagmus
Eye movement disorders may be considered in two categories: those that cause incomplete eye movements (ophthalmoparesis) and those that cause excessive eye movements (saccadic intrusions and nystagmus). Central to an understanding and correct diagnosis of abnormal eye movements is the evaluation of ocular alignment, ocular motility, and each functional class of eye movements: optokinetic, vesti...
متن کاملNystagmus and Related Ocular Motility Disorders
General Concepts and Clinical Approach This chapter concerns abnormal eye movements that disrupt steady fixation and thereby degrade vision. We now know a good deal about the normal anatomy, physiology, and pharmacology of ocular motor control (1). Our approach is to apply this knowledge to nystagmus and other ocular oscillations, since pathophysiology provides a sounder conceptual framework th...
متن کاملLithium-Induced Downbeat Nystagmus and Horizontal Gaze Palsy
We report a case of lithium-induced downbeat nystagmus and horizontal gaze palsy in a 62-year-old woman who was treated for a bipolar affective disorder with lithium carbonate for one month. At presentation serum lithium was within therapeutic range. No alternative causes of the ocular motility disturbances were found, and the patient improved significantly as lithium carbonate was discontinued.
متن کاملGaze-evoked eyelid and ocular nystagmus inhibited by the near reflex: unusual ocular motor phenomena in a lateral medullary syndrome.
Rhythmic movements of the upper eyelids are infrequent manifestations of brain-stem disease. Gowers (1879) noted the close coordination between movements of the upper lids and eyeballs in vertical nystagmus. He attributed this coordinated movement to the natural synkinesis of the levator palpebrae superioris and superior rectus muscles; this clinical observation was later verified electrophysio...
