Maryland police have shared a photo of a man found walking down Interstate 795 outside Baltimore last week who they said could not remember his own name.
“The man, who was described as having a slim build and was only wearing black shorts, required medical attention and was unable to remember his name or contact information for family members,” police said in a statement.
They are asking for the public’s help identifying him.
He is described as a white male with a slim build, and the photo shows he has brown hair and blue or hazel eyes, with a stubble beard.
Authorities took the man to a local hospital. In the photo, he has a cut on his nose.
After receiving medical treatment, he remained unable to recall his identity as of Thursday, police said.
Police said they found the man walking down I-795 near Owings Mills Boulevard in Baltimore County at about 9 p.m. on July 22.
The area is close to an intersection of two major highways on the northeastern outskirts of Baltimore.
Amnesia can be caused by several factors, including a traumatic brain injury, neurological diseases, viral infection and drug abuse, according to the National Library of Medicine. It can also be an early symptom of dementia.
