"Former professional footballers are at much higher risk of degenerative brain diseases, dementias and related disorders," says Prof Stewart, who is a consultant neuropathologist at the University of Glasgow.

Just before Sir Chris's tumour was discovered, Sarra had undergone scans that would later show she had multiple sclerosis, a degenerative disease.

Less than a year later, he was diagnosed with frontotemporal dementia, a degenerative brain disease that currently has no cure.

The 50-year-old athlete, who has a degenerative visual impairment called Stargart disease, will run the 200- and 400-meter events as part of the T12 classification.
