A brain MRI revealed cortical tubers suggestive of TSC. A subsequent echocardiogram showed the presence of multiple endomyocardial lesions suggestive of rhabdomyoma. Further follow-ups showed spontaneous resolution of these cardiac lesions, but persistence of brain disorders. We also describe the refractoriness of the convulsive events despite appropriate treatment with multiple anticonvulsants.</p></div><div><h3>Conclusions</h3><p>Neurological and cardiac implications in patients with DS/TSC association lead to a difficult therapeutic scenario with a high rate of complications, partially due to symptomatic refractoriness. New drugs aimed at the m-TOR signalling pathway could be very useful in this picture, given its relationship to improvement of cognitive impairment and tumours associated with these two entities.</p></div>","PeriodicalId":100720,"journal":{"name":"International Medical Review on Down Syndrome","volume":"20 2","pages":"Pages 21-24"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.sdeng.2016.04.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72258104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
