If you’re feeling persistently drained despite getting enough rest, a mini-stroke—known as a transient ischemic attack (TIA)—could be the hidden reason, according to new research from Denmark.
TIAs are brief interruptions in blood flow to the brain that can last up to 24 hours. While they often go unnoticed—only about 1 in 30 people realize they’ve had one—these “silent strokes” may have lasting effects. Common symptoms like headaches, temporary muscle weakness, or blurred vision are easy to dismiss, yet the damage can linger.
The new study, published in Neurology, tracked 354 patients over a year after experiencing a TIA. Researchers found that 61% reported increased fatigue just two weeks after the event. Half continued to feel exhausted up to a year later.
Lead researcher Dr. Boris Modrau of Aalborg University Hospital explained that the brain needs extra energy to recover from the temporary disruption, which can lead to long-term fatigue—even when outward symptoms seem to disappear.
Participants with a history of anxiety or depression were twice as likely to report ongoing fatigue, suggesting emotional health may also play a role.
Although the study is observational and doesn’t definitively prove TIAs cause chronic tiredness, it highlights the need for better post-stroke care. Dr. Modrau recommends regular fatigue screenings for TIA patients to identify those needing long-term support.
Fatigue after a mini-stroke can affect both the body and mind, leading to muscle weakness, difficulty focusing, disrupted sleep, and reduced overall quality of life.
