Background: There is evidence that channelopathies are the cause of many different neurological diseases. The epileptic perinatal encephalopathy due to mutation in the KCNQ2 gene is a rare disease involving severe tetraparesis and cerebral visual impairment. Diseases of this kind are associated with severe disability that involves multiple systems and requires accurate genetic diagnosis and early multidisciplinary care once clinical stability is reached.
Case report: We describe a case of a baby girl with KCNQ2 encephalopathy who came to our observation for rehabilitation at age 2 years and 6 months.
Clinical rehabilitation impact: We stress the importance of a correct clinical, pharmacological and visual diagnosis. Correct diagnosis made it possible to involve the baby girl and her care-giver in an early process of visual rehabilitation lasting 6 months, the effects of which proved to persist at follow-up after more than a year, making it possible to start a useful inter-professional rehabilitation plan.
