Wife......,

Have you looked for a Brain Injury Support Group in your area? Some have good support for caregivers/spouses. I know you want to inquire about his day and discuss other matters, but trying to respond when one is struggling with flat affect can be frustrating. Trying to avoid abstract questions or subjects may help. I know it is a struggle. Women tend to discuss more relational and feeling oriented subjects. The PCS mind can really struggle with those ideas.

My best to you.
