Treatment of amyotrophic lateral sclerosis - what is the next step?

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease which was thought to be untreatable. However, recent evidence in both experimental animals and men indicates that antiglutamatergic strategies are the first to have an influence on its pathogenesis and slow down the disease process. Since the effect of drugs is still small, this process cannot only be seen as a success of the present but must also be acknowledged as a basis for future developments. How will future studies be designed? They will have to take into account that the disease presumably has a long preclinical period and they will use a number of novel compounds and treatment strategies which have been shown to be effective in transgenic animal models. This also implies that we are likely to use a combination of therapies and we will try to treat patients early. The latter will be associated with the demand for a novel clinical attitude toward the diagnosis of the disease and the development of novel markers for both the preclinical period and the longitudinal course of the disease.
