However, no previous study has evaluated the use of the FIM in adults with PWS. This study aimed to assess functional independence in adults with PWS using the FIM and to explore the effects of age and genetic subtype on functional outcomes. We conducted a retrospective, single\u2010center study of 54 genetically confirmed patients with PWS of Japanese descent. No significant correlations were observed between age and FIM scores. Similarly, no significant differences were found between age groups or genetic subtypes in total, motor, or cognitive FIM domains. Radar chart analysis illustrated slightly lower FIM scores in older adults, although these differences were not statistically significant. These findings highlight the importance of individualized support plans tailored to age and specific functional needs. Early intervention in childhood, followed by continued support into adulthood, may be crucial for maintaining independence and enhancing quality of life in individuals with PWS.<\/jats:p>","DOI":"10.1002\/ajmga.70022","type":"journal-article","created":{"date-parts":[[2025,12,10]],"date-time":"2025-12-10T11:44:21Z","timestamp":1765367061000},"page":"879-886","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Functional Independence in Adults With Prader\u2013Willi Syndrome: First Report Using the\n                    <scp>FIM<\/scp>\n                    Instrument"],"prefix":"10.1002","volume":"200","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0130-0585","authenticated-orcid":false,"given":"Yuji","family":"Oto","sequence":"first","affiliation":[{"name":"Department of Pediatrics Dokkyo Medical University Saitama Medical Center  Saitama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Ogata","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Dokkyo Medical University Saitama Medical Center  Saitama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erina","family":"Nakane","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Dokkyo Medical University Saitama Medical Center  Saitama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sohei","family":"Saima","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Dokkyo Medical University Saitama Medical Center  Saitama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeshi","family":"Inoue","sequence":"additional","affiliation":[{"name":"Child Development and Psychosomatic Medicine Center Dokkyo Medical University Saitama Medical Center  Saitama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuyuki","family":"Murakami","sequence":"additional","affiliation":[{"name":"Nakagawanosato Ryoiku Center  Saitama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshiro","family":"Nagai","sequence":"additional","affiliation":[{"name":"Nakagawanosato Ryoiku Center  Saitama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9941-7310","authenticated-orcid":false,"given":"Satomi","family":"Koyama","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Dokkyo Medical University Saitama Medical Center  Saitama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomozumi","family":"Takatani","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Dokkyo Medical University Saitama Medical Center  Saitama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Ihara","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Dokkyo Medical University Saitama Medical Center  Saitama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,10]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nicl.2019.101664"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1017\/s001216220100202x"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.2174\/1573396315666190716120925"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/gim.0b013e31822bead0"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pmrj.2014.05.017"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/0003\u20109993(93)90119\u2010u"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.1320600612"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004583\u2010199211000\u201000023"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0223162"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jstrokecerebrovasdis.2024.108185"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0003\u20109993(98)90000\u20104"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/00002060\u2010199304000\u201000005"},{"key":"e_1_2_10_14_1","volume-title":"Adaptive Behavior Assessment System, Third Edition (ABAS\u20103)","author":"Harrison P.
