Attention Deficit Hyperactivity Disorder (ADHD) is often thought of as a condition of childhood, but up to 3% of the adult population also experience it. Impressionist and comedian Rory Bremner is one of those. He discusses his experiences with Jonna Kuntsi and Jessica Agnew-Blais from Kings College London who study how childhood and adult versions of the condition differ, whether we can predict which children continue to experience symptoms in adulthood, and a new proposal that the majority of adult ADHD might not have begun in childhood at all.

The first two parts of the All in the Mind Insiders' Guide to Mental Health Services ask how do you know when you have a mental health problem, and what should you say to your GP in order to get help. Our 'insiders' are service user, mental health campaigner and retired chief of an NHS Trust Lisa Rodrigues, GP and All in the Mind Awards finalist Daniel Dietch, Head of Information at Mind Stephen Buckley, and psychiatrist Sri Kalidindi.

And Claudia Hammond talks to Kavita Vedhara about a new study that shows once more that simply writing about how you feel can speed up wound healing. Although this effect has been known since James Pennebaker's landmark studies in the 1980's, this is the first study to demonstrate that expressive writing after an injury can aid healing as much as doing it in advance of a wound. An important finding since we don't always plan our wounds in advance.
