Symptoms After a TIA Attack

2025-04-29

A TIA (transient ischaemic attack) is a temporary disruption of blood flow to the brain. Although TIA symptoms disappear quickly, attacks can leave lasting signs such as fatigue, memory problems and an increased risk of stroke and dementia.

A TIA (transient ischaemic attack) is often over within minutes or hours, but that does not mean the brain has fully recovered. Even though symptoms disappear quickly, a TIA can leave subtle signs that the brain has been affected.

Recognising lingering symptoms is important – both to detect any damage and to prevent more serious events such as stroke and dementia. Read more about what a TIA attack is for a broader understanding.

What symptoms can persist after a TIA?

After a TIA, some people may experience:

  • Mild weakness or numbness in an arm, leg or face
  • Balance difficulties or a feeling of unsteadiness
  • Speech difficulties, such as slurred speech or difficulty finding words
  • Mild memory problems or difficulty concentrating
  • Fatigue and reduced energy levels

Symptoms can be very subtle and sometimes only appear under stress or physical exertion. Research shows that up to 15–20% of people who have had a TIA may continue to experience cognitive difficulties afterwards [1].

Why can symptoms persist even though TIA is defined as “transient”?

A TIA is defined as a transient disturbance because blood flow to the brain is restored before significant permanent tissue damage occurs [2]. However, even a brief lack of oxygen can cause microscopic damage to nerve cells. These small injuries can lead to subtle but noticeable difficulties in everyday life.

A TIA may also be a sign of underlying problems in the brain’s blood vessels – such as atherosclerosis or small vessel disease – which in themselves can affect brain function.

Link to dementia

A TIA is not only a warning sign for stroke – it is also a risk factor for dementia. Repeated small injuries to the brain can lead to gradual deterioration of cognitive functions, a condition known as vascular dementia [3]. Several studies have shown that people who have had a TIA have twice the risk of developing dementia compared to those without [3].

Typical early signs may include difficulty with complex tasks such as planning or decision-making, reduced mental speed, and problems managing multiple things at once. Identifying these problems early can open the door to treatment and support that may slow progression.

When should you seek medical care?

Contact a healthcare provider if after a TIA you experience persistent or worsening symptoms, new episodes of numbness or speech difficulties, or deteriorating memory and difficulties with everyday activities.

A TIA is always a signal that the body needs help. A thorough assessment and appropriate preventive treatment can reduce the risk of future strokes and protect the brain’s long-term health.

Safety alarm with automatic fall alarm

Sensorem’s personal alarm can automatically trigger the alarm in the event of a fall and then call relatives using the watch’s built-in speakerphone with two-way communication. The user can also trigger the alarm manually by pressing the physical alarm button. The personal alarm works outdoors and has built-in GPS positioning so that relatives can see the user’s position on a map in the Sensorem app.
