I’m not a Dr but my brother had a ruptured brain aneurysm twice and went through a long recovery period. I believe it will take some time to understand the extend of any damage. In my brother’s case the first rupture did not cause any long term issues but the second one did, actually few people survive a second rupture so he is lucky to be alive. He had difficulty talking and had some movement problems but with therapy, speech and physical, he has been able to regain most of it.

Your son is younger and that may help. It takes time for an aneurysm to develop and get to a size that ruptures so your son had had it for probably a few years. After my brother’s first rupture I got checked and I also had one, it was small but it had vascular access and I had it fixed. In my case they used a stent, my brother’s first repair was a coil like the tried with your son. Stents and coils are done endovascularly with a catheter, clips which may be what they finally did with your son are done with a craniotomy, they actually have to open the skull. After the second bleed my brother had to get a craniotomy and clips.

Find what resources are available to you regarding therapy, the neurosurgeon’s team should be able to guide you.

All the best
