24-year-old man who died over Christmas due to dementia has left his brain to researchers.
Andre Yarham, who lived in Dereham, Norfolk, was diagnosed with frontotemporal dementia due to a protein mutation a month before his 23rd birthday.
His mother Samantha Fairbairn said she hoped by donating his brain to science more could be found out about this "cruellest" of diseases.
According to Dementia UK, frontotemporal dementia is a rare form of the disease affecting about one in 20 people with a dementia diagnosis.
