Long-term AUD can affect a person s sense of taste and smell. This natural history study will compare alcohol drinking behaviors and measures of taste and smell in people with and without AUD.\n\nObjective:\n\nTo understand how alcohol use changes the senses of taste and smell.\n\nEligibility:\n\nPeople aged 18 to 65 years with or without AUD.\n\nDesign:\n\nParticipants will be screened. They will have several tests to assess their smell and taste functions. They will answer questions about their eating, alcohol use, and smoking or vaping habits.\n\nParticipants will have 2 study visits.\n\nThey will give samples of blood, nasal mucous, saliva, stool, and urine.\n\nTheir bodies will be measured. They will undergo a type of scan that uses X-rays to measure their body composition.\n\nThey will complete taste measurements. They will taste liquids by swishing them in their mouth, without swallowing. Then, they will be asked what they can detect and which flavors they preferred.\n\nThey will also complete smell measurements. They will be asked if they can identify strong odors on a metal wand. They will be asked to rate the intensity and pleasantness of odors.\n\nTheir brain activity in the frontal regions will be measured while they smell various odors. For this, we will use a brain imaging tool called functional near infrared spectroscopy.\n\nThey will have sensory testing. Sensations such as pressure, pinpricks, heat, or vibrations will be applied to their skin. Then, they will be asked what they felt.\n\nThey will keep diaries. They will write down what they eat (for 3 days), the alcohol they drink (3 days), and how much they sleep (14 days). They will wear a wristwatch-like device that records their activity for 14 days.",[68],"Alcohol Use Disorder",[70,71,72],"chemosensation","Preference","Natural History","2026-06-13",{"date":75,"type":76},"2026-06-16","ACTUAL",{"date":78,"type":76},"2024-01-09",{"date":80,"type":64},"2027-12-31",{"name":18,"class":6},1]
