Title: A Randomized, Double-Blind, Placebo-Controlled Sequential Clinical Trial of Sodium Valproate in ALS
Brief Summary: The purpose of this study is to determine whether the use of sodium valproate is effective in slowing the disease progression in Amyotrophic Lateral Sclerosis.

* A disease duration at inclusion of more than 6 months and less than 36 months \[inclusive\] (disease onset is defined as the date of first symptoms excluding muscle cramps and fasciculations)
* Vital capacity (VC%) ≥ 70% of normal value (slow expiration, best of a minimum of three and a maximum of five measurements, with a respiratory function validly assessable and a spontaneous, non-assisted ventilation)
* Ages 18 - 85 years (inclusive)
* Capable of thoroughly understanding the trial information given; has signed the informed consent.

Exclusion Criteria:

* Tracheostomy, tracheostomal ventilation of any type, non-invasive ventilation more than 16 hours/ day, or supplemental oxygen during the last three months prior to inclusion.
* Any medical condition or intoxication known to have an association with motor neuron dysfunction, which might confound or obscure the diagnosis of ALS.
* Presence of any concomitant life-threatening disease or any disease or impairment likely to interfere with functional assessment.
* Confirmed hepatic insufficiency or abnormal liver function (ASAT, ALAT greater than twice the upper limit of normal range).
