Sacha Slone discusses brain chemicals which could help keep the Victim of Narcissistic Abuse conditioned to remain in the relationship, not unlike a Drug Addiction. The biochemicals in the brain may also help create Trauma Bonding or Stockholm Syndrome.
The helplessness is learned, over time, using the Biochemistry created by using Reward and Punishment. Victims are trained to become dependent on the Narcissist. People outside of the abusive relationship can never understand why the Victim cannot leave such a relationship.
