Genetics and Environment iNtersection In the Amyotrophic Lateral Sclerosis - FrontoTemporal Dementia Spectrum: an Italian Twins Cohort studY With a Multi-Omics Approach
The goal of this study is to learn from discordant twins affected by Amyotrophic Lateral Sclerosis and/or Frontotemporal Dementia the contribution of genetic background versus environmental exposure. The main questions it aims to answer is: * How far does the genetic background explain the onset of ALS/FTD in discordant twins? * Which environmental factors and events occurring in post-fetal life influence the onset or progression of this neurodegenerative condition? Participants with ALS and/or FTD with a monozygotic or dizygotic twin willing to contribute to this research will be followed up for two years by specialized Motor Neuron Disorders centers in Italy, donating biological specimen for -omic sciences analysis, and checking out if prodromal signs/symptoms of these two conditions will develop during time.

• Subjects able and willing to comply with study procedures as per protocol
• Subjects able to understand, and capable of providing informed consent at screening visit before any protocol-specific procedures
