The use of WhatsApp Messenger: an important tool in modern neurological examination

WhatsApp Messenger is one of the most popular and still growing mobile applications worldwide in telemedicine. WhatsApp Messenger can be used as a communication tool and an adjunctive tool within telemedicine, but it is the ability or inability to use WhatsApp Messenger correctly that provides a powerful clinical neurological function tool. The easy use and the application’s popularity make it extremely useful in obtaining clues in patients’ neurological history. Dystextia or dystypia, the inability to send correct text messages, can be used as an indicator of neurological deficits, and is an upcoming term in neurological vascular pathology. In this case series, we present three cases in which the inability to send text messages were the clue for neurological pathology. This easy and useful evaluation of the ability to use a text message program should be incorporated in standard neurological history taking and examination, as it can provide clues for underlying neurological pathology.
