If you think you have a bad sense of direction, you may be relieved that there are people like Sharon Roseman, who suffers from Developmental Topographical Disorientation (D.T.D.), a rare neurological disorder that renders people unable to orient themselves in any environment.

Click here to watch The New York Times video describing this debilitating condition:

Before she was given the D.T.D. diagnosis, doctors told her she might have epilepsy or a brain tumor. She kept her condition a secret from her husband, worked close to home and was terrified of not being able to take care of her children in the event of an emergency. After the diagnosis, she says she felt validated for the first time in her life: “I can now talk freely about D.T.D. and teach others what it is, so that someday a young child can be diagnosed and not have to grow up being afraid.”
