Variants of Amyotrophic lateral sclerosis and rehabilitation: an overview

Amyotrophic lateral sclerosis (ALS) represents a progressive neurodegenerative disease that affects motor neurons in the brain and spinal cord leading to the impairment of volun-tary muscle control and eventually death. It accounts for about 80%-90% of all motor neu-ron diseases, and is characterized by a marked variability in terms of clinical forms, gene-tics, survival rate and diagnostic particularities. A diagnosis of ALS or one of the variants comes with a great burden for the patient and patient’s family because of the high morbidi-ty and mortality rate of this disorder. As a consequence, it is mandatory to optimize the ac-curacy of the diagnostic process of ALS spectrum for providing the best clinical manage-ment and quality of life for patients and avoiding diagnostic mistakes. Our review focuses on the general and particular aspects of ALS and its variants in an effort to improve the process of diagnosis, therapy and exclusion of mimics of this group of diseases and to pro-vide the latest findings in this field.
