What's the real difference between a night owl and a morning lark?

The Editors' Choice paper for the June 2026 issue of Practical Neurology is a review of all the ways sleep intersects with neurological practice. Last author Prof. Guy Leschziner¹ joins PN podcast editor Dr. Amy Ross Russell to the wide variety of sleep-related disorders: insomnia, hypersomnolence, and sleep-related movement disorders. Each category contains pitfalls to be avoided when treating, like overlooking critical signs or reaching for drugs too eagerly. You'll also learn about "sleep reactivity", teenage sleep patterns in the animal kingdom, and diagnostic insight that can be gained from partners.

The latest highlights from the journal are set to give confidence when trying something new. In this podcast for the June 2026 issue of Practical Neurology, co-editors Phil Smith and Geraint Fuller bring a distillation of the wisdom found in the journal's pages. They explain the crucial role of a Zeitgeber for healthy sleep cycles, question the involvement of drugs like SSRIs in seizures, and share a transatlantic follow-up to the ABN myasthenia gravis guidelines which provides an approach to optimising over all patient well-being. There's also a guide to recent treatment of Parkinson's using foslevodopa-foscarbidopa infusion, also known as Produodopa. Then the editors explore the structure of the retina while touching on optic neuritis, and finish with limb-shaking transient ischaemic attacks, an early warning signal for stroke. Listen to the very end for some editorial insight into practical uses for the podcast itself!

It's the return of Merlin. Not the birdsong identification app this time, but the Rolls-Royce Merlin - engine of the historic Supermarine Spitfire warplane. The Case Reports trio are faced with another set of patient puzzles to work through in this latest episode.

In the first case (1:25), a 68-yo man, retired from farming, presents with a 6-year history of behavioural changes. Most notably, he had developed a sense of great pleasure in listening to engine sounds, like those of the historic aircraft flying over his house. He had become increasingly emotionally detached and ritualistic, and gained a sweet tooth. MR scans of the brain revealed an uncommon syndrome.

The second case (21:15) relates to a 47-yo woman who developed abnormal movements in all of her limbs. She had undergone a complex cardiac surgery 12 years before, and another prolonged cardiac surgery within recent weeks. The case discusses the longterm follow-up of her treatment for these involuntary movements.

The case reports discussion is hosted by Prof. Martin Turner¹, who is joined by Dr. Ruth Wood² and Dr. Babak Soleimani³ for a group examination of the features of each presentation, followed by a step-by-step walkthrough of how the diagnosis was made. These case reports and many others can be found in the April 2026 issue of the journal.
