Hi and welcome to NT.

Your husband's injury sounds similar to mine, I also had a skull fracture requiring evacuation of a hematoma. The surgeon that performed the craniotomy later told be "I didn't think you were going to make it". That said, as you will hear, if you have seen one brain injury you have seen ONE brain injury. We all recover differently.

Has he had a neuropsychological assessment from a clinical neuropsychologist? If not that might be a place to start. Specific symptoms can often be helped by specific therapies, be that from a psychologist or from a speech pathologist or occupational therapist as music-in-me suggests. I personally benefitted greatly from their therapy.

Some affects for a TBI may be long lasting or permanent. 3 1/2 years on I still have occasional vertigo and unsteadiness in walking, and I use a cane when I'm out and about away from the house. Part of the recovery process can include making these types of adjustments.

As you have experienced, TBI recovery is usually measured by months or years rather then days or weeks. The very best to you both and you proceed along this recovery journey.
