Story summary

A Korean study of 1,441 adults finds moderate to severe obstructive sleep apnea (OSA) linked to higher cerebral microbleed risk.
The incidence among those with significant apnea is 4.66% at four years and 7.25% at eight years.
The authors say early diagnosis and treatment of OSA could help prevent future strokes and dementia.
Limitations include not assessing actual stroke or dementia outcomes and possible underestimation of microbleed incidence.
