Alisha Malhotra was 26 years old when she had a stroke that left her with the language disorder aphasia.

The condition, which impairs the production of speech and the comprehension of language, left Alisha having to learn how to speak again.

An aphasia clinic, The National Brain Appeal Aphasia Service, has opened at University College London Hospital, where they are using groundbreaking technology to help patients like Alisha regain their speech.
