How can i tell if my husband is just a paranoid person, or is something more?

3 or more of these?: Excessive sensitivity tendency to bear persistent grudges persistently and injuries or slights suspiciousness and a pervasive tendency to misconstrue the actions of others as hostile or contemptuous a combative and tenacious unreasonable sense of personal rights recurrent suspicions of sexual infidelity tendency to experience excessive self-importance preoccupation with conspiracies.

Need more info: Paranoia reflects excessive/unrealistic fear & possibly delusions. Can be very disabling if extreme. When you say "something more" do you mean another possible disorder or underlying medical condition? Or do you think there is justification for his paranoia (others are out to get him)? Have you had a frank discussion w/ husband? You and husband may need to see a therapist to get answers.
