Disease description:

I am the mother of a boy who is 8 years old. Recently, I noticed that he often sniffs his nose, especially during quiet moments, and the movement appears very unnatural. He doesn't show symptoms of a cold, but this behavior seems to be increasing in frequency. I would like to ask whether frequent nose sniffing in children could be a sign of tic disorder.

Nasal sniffing in children may be a sign of tic disorder, but a comprehensive evaluation combining other symptoms is required. Simple nasal sniffing is commonly seen in cases of nasal irritation or allergies, such as discomfort reflexes caused by dryness, foreign body sensation, or allergic rhinitis. Tic disorder is a neurodevelopmental condition primarily characterized by involuntary, repetitive motor movements or vocalizations, which are typically sudden and difficult to control. If nasal sniffing occurs irregularly, without clear nasal pathology, and is accompanied by other motor or vocal tics, tic disorder should be considered. Some children may develop repetitive behaviors due to habit formation or attention-deficit issues, which need to be differentiated from pathological tics.

Parents are advised to record the frequency and context of the nasal sniffing episodes, and observe whether they are accompanied by other movements such as eye blinking, shoulder shrugging, etc. Reducing environmental allergens like dust mites and using saline nasal irrigation to relieve nasal dryness may help. If symptoms persist beyond three months or interfere with social interaction or learning, consultation with a pediatrician or neurologist is recommended, including behavioral assessment and allergen testing. Avoid excessive focus on the behavior, which may increase anxiety; maintain a regular sleep-wake schedule, and psychological counseling may be necessary to manage emotional stress when indicated.
