This week's finalist in the All in the Mind Awards is Sian who's been nominated by her mother Myra who cannot believe how much support she has given her during a manic episode and her diagnosis of bipolar disorder. Even when Myra threatened to bite Sian, she still kept calm and understood that it was her illness which was affecting her behaviour. When she let her mum look after her beloved granddaughters, it helped Myra's confidence to grow. One of the Awards judges Maddie Leslay - who plays Chelsea in the Archers - found Myra and Sian's story really inspiring and full of unconditional love.

Prof Jenny Crinnion explains how speech therapists prompt people experiencing "tip of the tongue" difficulties with finding words during the intensive speech and language therapy.
