Immunofluorescence for phosphorylated alpha- synuclein in skin biopsy samples is an emerging biomarker in synucleinopathies comprising Dementia with Lewy bodies. In this pilot study, 19 patients with recent- onset (≤ 18 months) cognitive impairment underwent skin biopsy at baseline, with follow- up clinical re- evaluation. Five patients fulfilled the Dementia with Lewy bodies diagnosis, all of them positive for skin phosphorylated alpha- synuclein. The remaining 14 patients were all negative. Skin tissue immunofluorescence may represent a promising technique in identifying synuclein pathology in recent- onset cognitive decline: larger cohorts are needed to confirm our preliminary data.

Abstract
Immunofluorescence for phosphorylated alpha- synuclein in skin biopsy samples is an emerging biomarker in synucleinopathies comprising Dementia with Lewy bodies. In this pilot study, 19 patients with recent- onset (≤ 18 months) cognitive impairment underwent skin biopsy at baseline, with follow- up clinical re- evaluation. Five patients fulfilled the Dementia with Lewy bodies diagnosis, all of them positive for skin phosphorylated alpha- synuclein. The remaining 14 patients were all negative. Skin tissue immunofluorescence may represent a promising technique in identifying synuclein pathology in recent- onset cognitive decline: larger cohorts are needed to confirm our preliminary data.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
