More rigorous mechanistic validation, such as conditional knockout models and metabolic flux analysis, is required to distinguish driver roles from concomitant responses
Age-related deterioration of the central SCN clock has been demonstrated in animal models at molecular and electrophysiological levels (e.g., reduced amplitude of SCN clock gene expression and firing) and likely underlies some of these changes
According to NICE Clinical Knowledge Summaries, investigation of suspected B12 deficiency should include serum B12 measurement, full blood count, and assessment of clinical features
