Data regarding the relevance of brain derived neurotrophic factor (BDNF), a regulator of neuroplasticity, to sarcopenia in community-dwelling adults are scarce. We examined the association between plasma BDNF concentrations, sarcopenia and individual sarcopenia signatures in a well-characterised adult cohort.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Participants included 246 men and women aged 50\u201382\u00a0years (mean age\u2009=\u200963.6\u00a0years; 52% female). Muscle strength and skeletal muscle index (SMI) were assessed by hand dynamometry and dual-energy X-ray absorptiometry. Plasma BDNF concentrations were determined, in duplicate, with commercially available enzyme-linked immunosorbent assays. Sarcopenia and individual signatures of sarcopenia (i.e. low grip strength or low SMI) were diagnosed according to the EWGSOP2 algorithm.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Plasma BDNF concentrations were 47.6% higher in participants with sarcopenia than controls (P\u2009=\u20090.005), and demonstrated acceptable diagnostic accuracy (areas under the curves\u2009=\u20090.702, 95%CI\u2009=\u20090.597\u20130.806, P\u2009=\u20090.002, optimal cut-off &amp;gt;1645\u00a0pg\/ml).

Our findings complement existing data, supporting the presence of an intricate relationship between neural integrity and skeletal muscle health.
