A 53 year old male named Noah is brought to the emergency department by his son, who found him with an empty bottle of fluoxetine in his hand.
His son mentions that Noah was recently diagnosed with depressive disorder.
Upon physical examination, you realize that Noah has a body temperature of 38.9 degrees Celsius, or 102.02 degrees Fahrenheit, and a blood pressure of 162 over 95 millimeters of mercury.
In addition, Noah’s pupils appear dilated, and his muscles are very stiff.
Finally, neurological examination reveals that Noah has overactive reflexes.
Later that day, a 34 year old female named Amelia is brought to the emergency department by her husband.
He explains that Amelia has a medical history of schizophrenia, and a few days back she took multiple doses of haloperidol.
Upon physical examination, Amelia’s body temperature is 38.7 degrees Celsius or 101.66 degrees Fahrenheit, and her blood pressure is 170 over 100 millimeters of mercury.
Similarly to Noah, Amelia has muscle stiffness, but neurological examination reveals diminished reflexes.
All right, now, both Noah and Amelia seem to have some form of psychiatric emergency, which is when a psychiatric condition becomes life-threatening and requires prompt treatment.
For your exams, some high yield psychiatric emergencies include suicide attempts, serotonin syndrome, acute dystonia, neuroleptic malignant syndrome, tyramine-induced hypertensive crisis, and delirium tremens.
Now, a very relevant psychiatric emergency, not only for your exams, are suicide attempts.
Suicide is when someone takes their own life intentionally.
