Schizophrenia is a chronic condition characterized by positive symptoms (auditory hallucinations, delusion), negative symptoms (avolition, social withdrawal), and disorganized thoughts/behaviors. Although the pathophysiology is incompletely understood, several neurobiological mechanisms have been proposed. ⋯ Patients should be assessed for suicide risk, violence risk, inability to care for self, and the risk of being the victim of a crime. Persons with schizophrenia are at an increased risk of substance use and a variety of medical problems.

ReviewLegal and Ethical Considerations in Psychiatric Emergencies.
Individual rights can be limited in the context of psychiatric emergencies. The emergency physician should be familiar with state laws pertaining to involuntary holds. Physicians are equipped to perform a medical screening examination, address mental health concerns, and lead efforts to de-escalate agitation. The physician should conduct a thorough assessment and distinguish between malingering and mental health decompensation, when appropriate.

Anorexia nervosa (AN) and bulimia nervosa (BN) are easily missed in the emergency department, because patients may present with either low, normal, or increased BMI. Careful examination for signs of purging and excessive use of laxatives and promotility agents is important. Careful examination for and documentation of dental erosions, posterior oropharyngeal bruising, Russel's sign, and salivary and parotid gland inflammation are clues to the purging behavior. Treatment for AN should include cognitive behavioral therapy with concomitant efforts to treat any psychiatric comorbidities, whereas BN and BED have been successfully treated with fluoxetine and lisdexamfetamine, respectively.

ReviewDifficult Patients: Malingerers, Feigners, Chronic Complainers, and Real Imposters.
Malingering is the intentional production of false or grossly exaggerated symptoms motivated by internal and external incentives. The true incidence of malingering in the emergency department is unknown because of the difficulty of identifying whether patients are fabricating their symptoms. ⋯ Several case studies are presented and analyzed from a medical ethics perspective. Practical recommendations include use of the NEAL (neutral, empathetic, and avoid labeling) strategy when caring for patients suspected of malingering.

ReviewRecognizing and Responding to Patients with Personality Disorders.
Caring for patients with personality disorders and traits presents unique challenges for physicians and other providers. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, recognizes 10 personality disorders, which are organized into 3 clusters (A, B, and C) based on shared diagnostic features. Personality disorders or traits create difficulty in clinical and interpersonal interactions, promoting missed diagnosis or underdiagnosis, nonadherence to medical recommendations, or other dangerous outcomes. It is important to recognize patients with potential personality disorders and understand strategies to achieve optimal patient interactions and best possible medical outcomes.
