###Human: Why do I have deteriorating memory, paranoia and deja vu? ###Assistant: Hello. The symptoms could be due to severe anxiety. Progressive loss of memory, dissociation feeling, difficulty in articulation, racing thoughts, depressed mood, paranoia, difficulty in expressing, etc., could be due to anxiety.  But, if you are hearing voices which others cannot hear, and have a suspicion that someone is watching you, then that could be due to some underlying psychosis. This should be evaluated properly. Please visit a psychiatrist for an opinion. Try to remain relaxed and if possible ignore these symptoms.  For more information consult a psychiatrist online -->
