My almost 9 yr old is twitching/spasming in s front/chest

Customer Question

My almost 9 yr old is twitching/spasming in his front/chest area near the neck. I took him to vet Friday and they checked him and did x-ray and did not find anything but prescribed prednisone and a pain reliever. I can still see the movement and it appears it escalates at times and then calms down a bit but is not stopping. Do you have any clue of what can be causing this problem.

You've described a constant repetitive myoclonus - constant rhythmic twitching of musculature - which persists during activity, rest, and sleep. It can be a challenge determining the etiology of such a myoclonus but brain tumor is an important differential diagnosis in an older Boston. A complete physical and neurologic examination including a complete blood count, biochemistries, and urinalysis are indicated. Referral to a specialist veterinary neurologist should be considered because MRI is likely to be necessary to ascertain the etiology of his myoclonus. If this isn't possible, patients with a clinical syndrome of involuntary muscle contractions such as Cody may respond to an anticonvulsant trial. Phenobarbital, levetiracetam, or zonisamide are anticonvulsants to consider. Prednisone can be helpful when addressing idiopathic (unknown cause) corticosteroid-responsive tremor syndrome but such a syndrome wasn't described above.

Please respond with further questions or concerns if you wish.
