In the past few years several gene mutations have been identified as causative of the most frequent neurodegenerative dementias (Alzheimer disease and frontotemporal dementia). These advances, along with the complex phenotype-genotype relationships and the costs associated with genetic testing, have often made it difficult for clinicians to decide with regard to a rational plan for the investigation of the genetic etiology of the degenerative dementias. The Centro Hospitalar São João Neurogenetics Group, a multidisciplinary team of Neurologists and Geneticists with special interest in neurogenetic disorders, devised consensus recommendations for the investigation of the genetic etiology of Alzheimer disease and frontotemporal dementia in clinical practice, based on international consensus documents (currently containing partly outdated information) and published scientific evidence on this topic.

The primary dystonias are a particular group of dystonias of presumed genetic origin, with a wide age of onset and variable progression. The diagnosis is, therefore, a challenge and the issue of the genetic investigation presents frequently in clinical practice. In the past few years several gene mutations have been identified as causative of primary dystonias. Read More

Since the discovery of the first mutations that cause hereditary ataxias in the early 1990s, there has been continuous progress in deciphering the molecular pathogenesis of degenerative ataxias. Recent research in Friedreich's ataxia, the most frequent recessive ataxia, has provided further evidence that the clinical phenotype of this disorder is caused by abnormal oxidative phosphorylation due to mitochondrial dysfunction. The dominantly inherited spinocerebellar ataxias (SCAs) are genetically heterogeneous. Read More

Background And Objectives: The ataxias are a challenging group of neurological diseases due the aetiological heterogeneity and the complexity of the genetic subtypes. This guideline focuses on the heredodegenerative ataxias. The aim is to provide a peer-reviewed evidence-based guideline for clinical neurologists and other specialist physicians responsible for the care of patients with ataxia. Read More
