Being an expert in a neurology subspecialty offers advantages for diagnosing and managing specific disorders. However, specialisation also risks tunnel vision: interpreting symptoms and signs within one's own framework of reference, while ignoring differential diagnostic options from other subspecialties. This is particularly relevant when the patient's presentation potentially belongs to different neurological subspecialties. We illustrate this challenge by highlighting a series of clinical features that partially overlap between two common subspecialties: movement disorders and neuromuscular disorders. An overlap in clinical presentation is not rare, and includes, for example, involuntary eyelid closure (which could be active eye closure due to blepharospasm, or ptosis due to weakness). Other overlapping features include abnormal postures, involuntary movements and gait changes. We describe two of these overlapping features in more detail and emphasise the possible consequences of \u2018looking through the wrong end of the telescope\u2019 in such patients, as this may lead to a wrong differential diagnosis, unnecessary investigations and a delayed treatment start.<\/jats:p>","DOI":"10.1136\/practneurol-2015-001311","type":"journal-article","created":{"date-parts":[[2016,7,14]],"date-time":"2016-07-14T09:06:54Z","timestamp":1468487214000},"page":"264-269","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":15,"title":["The
