Susannah Cahalan got her start in journalism in the summer after junior year, when she got an internship at the New York Post, and worked her way up from grabbing coffee and making photocopies to a general assignment reporter.
One day in early 2009, Cahalan woke up in a strange hospital room, strapped to her bed, under guard, and unable to move or speak. Her medical records from a month-long hospital stay showed psychosis, violence, and dangerous instability. Her New York Times bestselling memoir Brain on Fire chronicles the swift path of her illness and the lucky, last-minute intervention led by one of the few doctors capable of saving her life. As time passed and she moved inexplicably from violence to catatonia, $1-million worth of blood tests and brain scans revealed nothing. The exhausted doctors were ready to commit her to the psychiatric ward, in effect condemning her to a lifetime of institutions, or death, until Dr. Souhel Najjar joined her team. He asked her to draw a simple sketch of a clock, which became key to diagnosing her with a newly discovered autoimmune disease in which her body was attacking her brain.
Also in 2009, Cahalan was the recipient of the Silurian Award of Excellence for the article “My Mysterious Lost Month of Madness,” on which Brain on Fire is based. Her work has also been featured in The New York Times, Scientific American, Psychology Today, and Focus, and she still works for the New York Post, now as their books editor.
As a huge fan of Brain on Fire, I emailed Cahalan requesting an interview, and we spoke on the phone shortly afterward.
When did you decide that writing was something that you wanted to pursue?
Probably for as long as I can remember. You know, those are the classes I enjoyed most. I kept journals when I was really a little kid, I still have them.
