Systemic Sarcoidosis Mimicking a Behavioural Variant of Frontotemporal Dementia

open access: yesCase Reports in Neurological Medicine, 2015
Among rare neurological manifestations, a progressive dementia may exceptionally be the revealing clinical feature of a sarcoidosis. Diagnosis may then be difficult, especially when systemic signs are missing or latent, with a risk of therapeutic delay ...

Rapid Nasal Breathing as a Biometric Trigger: High‐Accuracy Electroencephalogram‐Based Authentication for Clinical Applications

open access: yesThe Clinical Respiratory Journal, Volume 20, Issue 1, January 2026.
Our study demonstrates rapid nasal breathing‐evoked EEG signals enable high‐accuracy (98.3%) biometric authentication via a hybrid ResNet‐Swin Transformer model. This noninvasive approach eliminates external stimuli, offering secure patient identification for critical respiratory care settings, such as ventilator access and continuous monitoring ...
