- SECOND GROUP: Control subjects to premotor gene mutation carriers (CTR):

- 18-90 years of age
- provision of a written informed consent
- affiliation with a social security scheme or beneficiary of such a scheme
- Patients with pure motor symptom or early ALS (EALS) or ALS mimics (MIM)
- EALS are patients with pure motor symptom / early motor symptoms of ALS, including those, where the diagnosis of ALS can already be made. These may be patients who meet the following criteria:
- According to El Escorial criteria : patients who can be classified as possible ALS or those who show upper motor neuron (UMN) signs only or lower motor neuron (LMN) signs only, so that classification as possible ALS is also not possible. Symptoms should not persist for more than 12 months.
- According to Gold Coast criteria: Patients who do not fulfill the criterion of temporal progression or patients who only show UMN signs or only LMN signs in one region and thus do not fulfill the diagnostic criteria of ALS.
