Subjective cognitive complaints are heterogeneous and may occur with normal, subtle, or objectively abnormal cognitive testing. Fluorodeoxyglucose (FDG) PET can help explore their metabolic substrate, particularly in subjective cognitive decline within the Alzheimer's disease continuum. In mild traumatic brain injury and long coronavirus disease (COVID), available studies suggest possible metabolic-network abnormalities but involve more heterogeneous populations and should be interpreted cautiously within multimodal, clinically characterized frameworks.
