As with any Darwinian subject, neurology is under constant evolution. This podcast for the April 2026 issue of Practical Neurology has co-editors Phil Smith and Geraint Fuller taking a look at some intriguing specimens from the neurological field. Populating the menagerie for this episode are the "reversed clock phenomenon", a new study on brain problems in retired sportspersons, a practice guide for biosimilar drugs, and a look at GLP-1 drugs. Also found inside are the "nocebo effect", radiologically isolated syndrome for multiple sclerosis identification, and a weighing up of stenting vs shunting.

What unsuspecting dangers lie within a garden compost bin? The Case Reports team are back to uncover a new pair of neurological mysteries.

The first case this episode (1:24) comes from Edinburgh, centred on an 88-yo woman who presents with headache and eye-pain on her right side. She receives an early diagnosis of migraine, but returns a few weeks later with intermittent vomiting and subsequent progressive visual loss.

The second case (19:51) from Wessex features a common presentation of tingling feet, with a 62-yo man who develops gait instability. More curious are a significant drop in his weight, as well as a scaly patch on his chest.

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 October 2025 issue of the journal.

Many patients will affirm seeing clouds shaped like animals or other similar phenomena, which is why confirming pareidolia (seeing meaningful images in meaningless visual stimuli) is such a tricky symptom in dementia with Lewy bodies (DLB). While it may not be exclusive to DLB, placing such symptoms in the context of "the company it keeps" is a key method to narrowing down the diagnosis. The Editors' Choice paper for the February 2026 issue of Practical Neurology is a practical guide to the clinical diagnosis and management of DLB. Authors Dr. Sarah Fullam¹ ² and Dr. Seán O'Dowd¹ ³ join PN podcast editor Dr. Amy Ross Russell to discuss their work. They describe the importance of the initial examination, from the patient's gait to difficulties in word retrieval. They also touch on challenges in the use of biomarkers, which drugs may be helpful, and how to advise patients and their carers.
