Anterograde amnesia is the loss of the ability to create new memories, leading to a partial or complete inability to recall the recent past, even though long-term memories from before the event which caused the amnesia remain intact.

Antisocial personality disorder is characterized by a long-standing pattern of a disregard for other people’s rights, often crossing the line and violating those rights. It usually begins in childhood or as a teen and continues into their adult lives. Antisocial personality disorder is often referred to as psychopathy or sociopathy in popular culture.

They may have an inflated and arrogant self-appraisal (e.g., feel that ordinary work is beneath them or lack a realistic concern about their current problems or their future) and may be excessively opinionated, self-assured, or cocky.

Autophagia (eating one’s own body) is not classified as a mental disorder or a symptom of a mental disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM), the diagnostic manual used in the United States. However, Autophagia could be classified under the DSM’s Impulse-Control Disorders Not Elsewhere Classified.

Once the act has been completed, the individual may or may not feel regret, self-reproach, or guilt. Autophagia occurs when one is compelled to inflict pain upon oneself by biting and/or devouring portions of one’s body.

Post Traumatic Embitterment Disorder
Posttraumatic embitterment disorder (PTED) is a proposed disorder modeled after posttraumatic stress disorder. Some psychiatrists are proposing this as a mental disorder because they believe there are people who have become so bitter they can barely function. PTED patients do not fit the formal criteria for PTSD and can be clinically distinguished from it, prompting the description of a new and separate disorder.
