Neurological dysphagia: lack of/poor innervation to muscles in chewing/swallowing ie. cause=stroke, (cid:271)(cid:396)ai(cid:374) i(cid:374)ju(cid:396)(cid:455), alzhei(cid:373)e(cid:396), al , (cid:373)eds=t(cid:396)a(cid:374)(cid:395)uilize(cid:396) (cid:894) (cid:374)eu(cid:396)al a(cid:272)ti(cid:448)it(cid:455)(cid:895), a(cid:374)ti(cid:272)holi(cid:374)e(cid:396)gi(cid:272)s (cid:894) (cid:373)us(cid:272)le spas(cid:373)s(cid:895) Mechanical dysphagia: structural damage to muscles of oral cavity inflamm/infection/dysfunction. Other causes: surgical alterations to git, radiation of head/neck, aging. Fail to cough in response to food in trachea. food pass unnoticed in lungs [aspiration] overgrowth of bacteria pneumonia. S&s: sob, breathing problems, moist rales (crackles) on auscultation. Pem, dehydration, micro. def; hospital sta(cid:455); death; skin breakdown, fatigue. Physiology of normal swallow 4 phases: oral prep phase: chew food bolus moved to top of tongue (sensory receptors detect info texture, t-carried to brainstem to motor cells that rep chewing muscles). Swallow reflex propels bolus backward &down; gag reflex propels bolus upward &out: esophageal phase: ues opens -allow bolus to enter esophagus peristalsis thru les stomach. Diagnosis: clinical assessment of s&s, tolerance to foods/fluid consistencies.
