Your husband needs to be seen and tested by psychiatric clinicians...preferable a physician or psychologist who specializes in addiction medicine and is certified by the American Society of Addiction Medicine (ASAM).
what is slangily called "wet brain" in AA is actually a result of organic and often irreversible brain damage done in the course of long term alcohol consumption. However....one must not be too quick to make assumptions. I've known alcoholics who literally had to learn to read, write and even speak all over again, and required about six months to overcome the symptoms you are describing. And who seem to have entirely recovered.
So don't give up hope...but do everything you can to gain access to the proper psychiatric expertise.
