Police Scotland is appealing for information to help trace Michael Fitzpatrick who was reported missing from his home in Bainsford.
Michael, who is 5ft 10in tall with short brown hair, was last seen in Haugh Street at around noon on Friday, April 17.
He was reported missing during the evening of Sunday, April 26 having been out of contact with his family.
Police enquiries so far suggest he may have travelled to Edinburgh and then on to Berwick-on-Tweed by train.
It is possible he may be camping wild.
Sergeant Fiona Picken, of Falkirk Police Station, said: “It is out of character for Michael to be out of contact with family or friends for an extended period and he have concerns for his welfare as a result.
“We would urge anyone who may have seen him at any time since April 17 to let us know as soon as possible.”
Anyone with information can contact Police Scotland by calling 101 and quoting incident 3309 of April 26.
