Presumptive Cerebral Microbleeds in Dogs: A Common Yet Underrecognized Finding in Aging Canines
With advances in veterinary medicine and improved pet care, dogs are living longer than ever before. As the canine population ages, age-associated neurological changes—once rarely diagnosed—are now more frequently encountered on brain imaging. One such change is presumptive cerebral microbleeds (pCMBs), an MRI finding increasingly recognized in elderly dogs.
Is Your Patient’s Epilepsy Hiding a Bigger Problem? The MRI Findings That Could Change Everything!"
Researchers at the University of Liverpool examined over 400 epileptic dogs with normal neurological exams between seizures. While most had no obvious structural issues, 3.9% were found to have serious underlying conditions, including brain tumors, congenital anomalies, and inflammatory diseases. The risk increased dramatically with age—older dogs and those with a history of prolonged seizures were far more likely to have an underlying structural cause.
