Frequent Deja vu that feels real to my husband

@elm123 Have you already talked with your husband's doctor about this symptom? This is very frightening and I can understand if you feel frustrated wit this. You mention that he has already had short term memory problems but does not have a diagnosis.

Here is something to read about Déjà Vu from Cleveland Clinic. The key is how often your husband experiences this.

Cleveland Clinic: Déjà Vu: What it is and why it happens:

There could be many reasons why your husband reports this experience of "having been there before". It's possible that knowing he has short term memory problems and not remembering that this a way he compensates. Or, it could be something else. If this were my husband I would want the doctor to check this out and ask for a referral to a specialist. Many medical centers have Memory Diagnostic Centers that specialize in memory assessments.

Here is an example one clinic at Johns Hopkins in Baltimore:

Do you have any other information that might be helpful to share so that others can provide you with support?

Thank you for posting the seizure article. Very insightful for me. Although my husband is treated for petit seizures, perhaps he is experiencing a subtle seizure that manifests itself in deja vu. He regularly says Ive been here, I’ve seen this, i remember going to this place or that. But its all false, and i no longer say anything back. MCI diagnosis 14 years ago. He is still very functional each day which Ive finally come to count as huge blessing instead of fighting about everything.
We have no neurologist at this time. Many do not specialize in dementia so its not worth going to them. For now i just wait for the next symptom to hit him and pray im up to the task.

@rubyredkate Thank you for your comment. I'd like to highlight something you said about not making a comment when your husband experiences déjà vu. For a person with dementia or MCI it's better for communication and for the relationship if you go along with what the person said even if you know it is incorrect. This can actually be a conversation starter such as "tell me about this place", or "is there more about that TV show you'd like to share?" or something like that. I don't think there is a safety issue here so why not go along?
