    • Limited amount of insight into the systems
    • Negative consequences are often blamed on society.
    • Treatment options are limited.
    • Some research has found long term insight oriented therapy to be effective, but getting the individual to commit to this treatment is a major obstacle.
    • Impact on the sufferer and their family and/or those close to them
    • Sufferers do not express a particular desire to change themselves or suppress their impulses.
    • Many do not even know they are afflicted.
    • It is a cruel personality disorder which takes away nearly all the empathy from the victim and replaces it with an empty hole of hatred and arrogance.
    • A considerate and sympathetic behaviour towards the victims by family and friends is required.
