TIAs linked to cognitive function deficit

Patients who have suffered a TIA have poorer cognitive function than patients who have not had an attack, UK research suggests.

Cognitive impairment is associated with vascular risk factors, but the relationship between cognitive status and cerebrovascular risk is not fully understood.

This latest study, presented last week at the European Stroke Conference in Stockholm, compared cognitive function in patients who had suffered a TIA with a control group of healthy patients.

The Montreal Cognitive Assessment test (MoCA), consisting of 30 points, was used to assess concentration, language, attention and recall skills in the patients.

The research team, led by Dr Veronique Guyomard from Norfolk and Norwich University Hospital, found that patients who had suffered a TIA had poorer cognitive function.

This was indicated by a lower mean MoCA score (24.97) compared with the control group (28.39).

The researchers concluded that the findings suggest that measuring cognitive function should be part of routine TIA assessment.
