Aphasia is a communication disability which occurs when the communication centres of the brain are damaged.

It is usually caused by a stroke, brain haemorrhage, head injury or a brain tumour.

Aphasia makes it difficult to read, write or speak. It affects people differently.

Some people are unable to speak at all, others may have difficulty finding the right words to say or have difficulty reading, writing or using numbers

It affects  relationships, employment, educationsocial lives and confidence. 

Aphasia affects around 350,000 people in the UK, yet not many people have heard of it. The fact that this condition is rarely heard of, contributes to the loneliness that aphasia sufferers experience.
