Stroke: Difficulty swallowing is a possible sign – other uncommon symptoms to know

The NHS says occasionally a stroke can cause complete paralysis of one side of the body, sudden loss or blurring of vision, dizziness or confusion.

Other possible signs include difficulty understanding what others are saying, problems with balance and coordination, a sudden and very severe headache resulting in a blinding pain unlike anything experienced before or loss of consciousness.

The health body says the best way to help prevent a stroke is to eat a healthy diet, exercise regularly, and avoid smoking and drinking too much alcohol.

It adds: “A low-fat, high-fibre diet is usually recommended, including plenty of fresh fruit and vegetables (five A Day) and wholegrains.”
