This has a strong practical value as acute presentations to the emergency department can be avoided in these susceptible individuals. Usual medical and dietary advice in the treatment of DRD would include the avoidance of high-dose phenylalanine-containing products, and to this we would advocate the avoidance of high-dose aspartame-containing products.<\/jats:p>","DOI":"10.1136\/practneurol-2018-001900","type":"journal-article","created":{"date-parts":[[2019,1,30]],"date-time":"2019-01-30T23:11:10Z","timestamp":1548889870000},"page":"268-269","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Dystonic crises in dopa-responsive dystonia induced by energy drinks"],"prefix":"10.1136","volume":"19","author":[{"given":"Wilson K W","family":"Fung","sequence":"first","affiliation":[{"name":"Alfred Hospital, Melbourne, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelly L","family":"Bertram","sequence":"additional","affiliation":[{"name":"Alfred Hospital, Melbourne, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,1,30]]},"reference":[{"key":"2025090411183439000_19.3.268.1","first-page":"39","article-title":"Evaluation of caffeine, aspartame and sugar contents in energy drinks","volume":"6","author":"Abechi","year":"2014","journal-title":"J Chem Pharm Res"},{"key":"2025090411183439000_19.3.268.2","unstructured":"Sugar free energy drink.
