BACKGROUND The body of literature on oral motor and swallowing disorders in patients with ataxia telangiectasia (AT) is limited. CASE REPORT The purpose of this study was to characterize oral motor and swallowing disorders in two siblings with AT, based on oral motor and swallowing assessments. Specific procedures were applied for oral motor and swallowing assessments and both patients underwen...

Brain-derived neurotrophic factor (BDNF) acts as an anorexigenic factor in the dorsal vagal complex (DVC) of the adult rat brain stem. The DVC contains the premotoneurons controlling swallowing, a motor component of feeding behavior. Although rats with transected midbrain do not seek out food, they are able to swallow and to ingest food. Because BDNF and tropomyosin-related kinase B (TrkB) rece...

INTRODUCTION  The act of swallowing depends on a complex and dynamic process which uses common structures to the act of breathing; respiratory problems can cause swallowing difficulties. AIM  To assess the swallowing pharyngeal phase in patients with chronic cough. METHOD  Retrospective study with 15 patients of both genders, patients with chronic cough and risk factors for aspiration defin...

The tongue is important for orofacial movements, including swallowing. Although numerous studies have focused on tongue pressure against the palate, its physiological role has not been fully evaluated. The tongue pressure generation may have the temporal coordination with the swallowing relational organs. The aim of this study was to clarify the physiological mechanisms of tongue pressure and t...

BACKGROUND Swallowing changes are commonly observed in Parkinson's and Parkinsonism plus syndromes. Expeditious identification is necessary to provide early intervention in this population to avoid risk of aspiration and swallowing complications. OBJECTIVE To investigate swallowing problems using detailed case history and swallowing speed on 3 ounce water test in three groups i.e. PD, MSA and...

CONTEXT Breathing and swallowing coordination, despite the expressive number of study, remain as theme deserving further research. OBJECTIVE To identify a coordination pattern between swallowing and the natural breathing pause that occur in association with it (swallowing apnea) and also the relevance of the vocal folds closure in this process. METHODS Sixty-six adults, male and female, inc...

the reliability of surface electromyographic (semg) variables during swallowing determines the potential usefulness of these measures in swallowing assessment and treatment. this study aimed to establish the reliability of the semg measures of the swallowing function of muscles during different swallowing conditions in healthy young and old volunteers. two groups of volunteers (24 older adults,...

Non-nutritive swallowing occurs frequently during sleep in infants and is vital for fluid clearance and airway protection. Swallowing has also been shown to be associated with prolonged apnea in some clinical populations. What is not known is whether swallowing contributes to apnea or may instead help resolve these clinically significant events. We studied the temporal relationships between swa...

The nervous mechanisms that generate swallowing are still largely unknown. It has been suggested that a central pattern generator that contains a serial network of linked neurons must produce the successive excitation of motoneurons (Mns) and then the sequential activation of muscle through excitatory connections. Inhibitory connections have also been envisioned but never evidenced at the membr...
