Aspects of paediatric dysphagia are introduced covering definition, differentiation, child’s development, aetiology, diagnostics, therapy and management. Feeding disorders are also presented in detail, covering terminology, aetiology, epidemiology, clinical symptoms, diagnostic procedures and therapy. To explain neurogenic dysphagia, an overview is given of functional neuroanatomy related to swallowing. Neurogenic dysphagia characteristics are listed, as seen in diseases affecting various levels of the nervous system, and associated symptoms (comorbidities) are presented. Neurological and psychiatric disorders are discussed in context with psychogenic swallowing disorders, including globus hystericus and considering dysphagia as a possible side effect of antipsychotic drugs. Dysphagia after head and neck tumour treatment (surgery, radiotherapy, chemotherapy, combined interventions) is addressed, also highlighting special aspects in diagnostics and monitoring of head and neck cancer patients with swallowing disorders. Prevalence, risk factors, symptoms, sequelae, diagnostics and rehabilitative options of dysphagia in the elderly are described. The definition, characteristics and distinctive features of supragastric belching are discussed, as are its diagnosis and therapy. The incidence, mechanisms of development of post-intubation dysphagia, evaluation of swallowing in patients after orotracheal intubation tube removal and management of post-intubation dysphagia are presented in detail.
