This research was conducted through a&nbsp;literature review&nbsp;and the presentation of a 2.5-year-old girl diagnosed with hyperammonemia.<br> <strong>Case Presentation</strong>: The research was conducted on a 2.5-year-old girl who had been diagnosed with a sudden-onset metabolic disorder that resulted in swallowing, speech, and language problems. The child&rsquo;s receptive and productive language&nbsp;and&nbsp;feeding history&nbsp;were obtained through interviews with her mother. Formal and&nbsp;informal tests&nbsp;were used to assess the child&rsquo;s language and feeding skills at two different times after the onset of symptoms.<br> <strong>Discussion</strong>: This study presents a new and unique case of a child with very high levels of ammonia and&nbsp;severe clinical manifestations&nbsp;of cognitive, language, and motor dysfunctions. Although the child did not receive any direct interventions during the study, a&nbsp;secondary assessment&nbsp;revealed slight improvements in some language and&nbsp;oral motor skills, possibly due to maturation and advice provided by rehabilitation team members.</span></span></span></div> Hyperammonemia, Metabolic disease, Communication, Swallowing, Feeding 717 728 http://irj.uswr.ac.ir/browse.php?a_code=A-10-1754-2&slc_lang=en&sid=1 Shamim Ghazi shamimghazi1997@gmail.com 0000-0002-0298-3261 No Department of Speech Therapy, School of Rehabilitation Sciences, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.
