Temporary Blindness: A Hidden Brain Tumour Symptom

A lesser-known symptom of brain tumours involves temporary vision loss that resolves within seconds. Specialists note that brief episodes of vision changes, especially when standing up, might indicate pressure on the optic nerve or swelling at the back of the eye. Blurred vision or temporary 'greying out' lasting only a few seconds are among these potential indicators.

While brain tumours are rare, with over 12,000 diagnoses annually in the UK, they have a profound impact. These tumours reduce life expectancy by an average of 27 years, the highest of any cancer. Currently, at least 88,000 people in the UK are living with a brain tumour, with both cancerous and non-cancerous types being prevalent.

Experts emphasize that vision changes are not always indicative of a brain tumour, but any persistent or concerning symptoms should be checked by an optician. The Brain Tumour Charity provides guidance on recognizing symptoms, stressing that early diagnosis offers the best chance of fighting the disease.
