What Causes Spinal Stenosis?
Such symptoms cant occur in spinal stenosis
Detailed Answer:
Hello thanks for asking from HCM for your health related queries
I can understand your concern. He is having mild MR and have spinal stenosis at C3-C7 level. He is showing episodes of blacking out. For his age and clinical condition a number of possible reasons can cause such symptoms.
Spinal stenosis can result in dizziness but yes, it cant cause black outs because the stenosis is below the vital structures of brain. Even after sudden fainting due to stenosis he would remain conscious. So in general this has been ruled out.
His scan came normal and there is no evidence of bleeding so any hemorrhagic or vascular cause for his symptoms can be ruled out easily.
One possible reason for his symptoms, can be altered blood supply to brain. Some times due to postural hypotension when individuals get up after lying down or after sitting for prolonged periods they may suffer sudden blacking out and fall. This occur due to lack of blood supply to brain and more blood to dependent areas like legs. Get his blood pressure checked in lying down position and then immediately in standing position. Discuss with his doctor for any evidence of postural hypotension.
Other possible reason for his symptoms is some seizure discharge from brain. He is mildly mentally retarded and a lot of individuals with MR have seizures episodes. They may show partial or generalised seizures which can present like sudden fall. Get his EEG done to rule out any evidence of seizure discharge. Look out for any abnormal movements of arms and any frothing during such episodes which can further confirm diagnosis of seizures.
Get his evaluated with his doctor if such symptoms occur again.
Thanks, I hope this helps you. Still have some doubts then please don't hesitate to ask again in follow up.
Take care
