Willige. Arsenic treatment of organic diseases of the nervous system. Ueber Arsenbehandlung organiscber Nervenkrank-heiten. —Münchener medicin. Wochenschr. 1910, S. 621

The use of various arsenic compounds in parasyphilitic diseases of the nervous system was accompanied by an improvement in the general condition of the patients, but the objective symptoms of the underlying disease remained unchanged. The same results were obtained by the author in a number of other organic diseases of the nervous system (polyneuritis, Friedreich's disease, etc.), and only in the treatment of sclerosis disseminata in most cases an undoubted improvement was obtained.

Willige applied arsenic therapy in 12 cases of this disease; in 3 of them, which are among the severe, far advanced, the condition of the patients remained without significant changes, in the rest, an undoubted improvement was achieved both in the subjective state and in objective phenomena.
