Pat Preston, 65, shocked her husband, Michael, 66, after waking up from her collapse and immediately uttering a naughty four-letter word.
Since then, the pensioner just can't stop her foul language - but she hasn't always been so loose-lipped.
She was quoted in the Daily Express explaining: "Before I had a stroke I would get annoyed at things but I could control my upset. Now I just can't help it."
The retired bank customer service advisor has even called her grandchildren "little b********".
The Gateshead-based lady had the stroke back in January while shopping and was immediately rushed to the Queen Elizabeth Hospital, where she stayed for six weeks.
Pat admitted that her husband is sometimes pretty horrified with what she says, and added: "I can get a little nervous about what language I might use."
Marie Twentyman, a specialist stroke nurse, said: "Patients can have a change of personality following a stroke. Sometimes words get mixed up in the brain and vocabulary that would not normally be used by a patient is."
