Less is known about the context of cognitive deterioration among patients with atypical Parkinsonian syndromes and glucose metabolism impairment. The aim of this study was to evaluate the association between the impaired glucose metabolism and cognitive decline among patients with progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS). The study included 22 patients with PSP and CBS with disease durations varying from 3 to 6 years. The levels of glycated hemoglobin (HbA1C), fasting blood glucose, fasting C-peptide and the presence of microalbuminuria were evaluated, and oral glucose tolerance tests (OGTT) were performed. Based on the OGTT results, the glycemic variability, mean glycemia, glycemia standard deviation (SD) and coefficient of variation (%CV) were calculated. All patients underwent a three-Tesla brain magnetic resonance (MRI) examination and neuropsychological cognitive assessment with the use of standardized scales: Montreal Cognitive Assessment (MoCA), Mini-Mental State Examination (MMSE) and Frontal Assessment Battery (FAB). A statistical analysis revealed that poor control of glycemia with high glycemic variability and increased atrophy of the medial temporal lobe among patients with PSP and CBS correlated with worse cognitive performance independent of age or sex, even among patients who did not fulfill the criteria for diabetes. The study results indicate the importance of glucose metabolism control and optimal treatment in the context of cognition maintenance among patients with PSP and CBS. Due to the relatively small number of analyzed patients, the issue requires further assessment. To the best of our knowledge, this is the first study discussing the role of glycemic variability in atypical Parkinsonian syndromes.<\/jats:p>","DOI":"10.3390\/jcm13020465","type":"journal-article","created":{"date-parts":[[2024,1,15]],"date-time":"2024-01-15T07:25:07Z","timestamp":1705303507000},"page":"465","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Glucose Metabolism and Cognitive Decline in Progressive Supranuclear Palsy and Corticobasal Syndrome: A Preliminary Study"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8685-475X","authenticated-orcid":false,"given":"Natalia","family":"Madetko-Alster","sequence":"first","affiliation":[{"name":"Department of Neurology, Medical University of Warsaw, Kondratowicza 8, 03-242 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dagmara","family":"Otto-\u015alusarczyk","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Medical University of Warsaw, Banacha 1, 02-097 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0181-3607","authenticated-orcid":false,"given":"Marta","family":"Struga","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Medical University of Warsaw, Banacha 1, 02-097 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2202-9237","authenticated-orcid":false,"given":"Micha\u0142","family":"Kuty\u0142owski","sequence":"additional","affiliation":[{"name":"Department of Radiology, Mazovian Brodno Hospital, Kondratowicza 8, 03-242 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agnieszka","family":"Drzewi\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Neurology, Mazovian Brodno Hospital, Kondratowicza 8, 03-242 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karolina","family":"Duszy\u0144ska-W\u0105s","sequence":"additional","affiliation":[{"name":"Department of Neurology, Mazovian Brodno Hospital, Kondratowicza 8, 03-242 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bartosz","family":"Migda","sequence":"additional","affiliation":[{"name":"Diagnostic Ultrasound Lab, Department of Pediatric Radiology, Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5371-6817","authenticated-orcid":false,"given":"Piotr","family":"Alster","sequence":"additional","affiliation":[{"name":"Department of Neurology, Medical University of Warsaw, Kondratowicza 8, 03-242 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"853","DOI":"10.1002\/mds.26987","article-title":"Clinical diagnosis of progressive supranuclear palsy: The movement disorder society criteria","volume":"32","author":"Respondek","year":"2017","journal-title":"Mov.
