Method for the treatment of consciousness disorders

1. A method for the treatment of a consciousness disorder comprising:

a) positioning at least two electrodes on a patient's head such that the first electrode is positioned over the right supraorbicular cortex and the second electrode is positioned over the left dorso-lateral prefrontal cortex;

b) connecting said electrodes to at least one source of electrical current;

c) delivering direct current to the electrode, wherein an intensity of the direct current increases progressively during a period of time T′, wherein T′ is at least 1 second and at most 5 minutes, and

d) removing the electrodes from the patient's head after a time T;

wherein a) to d) represent a treatment session and wherein at least one treatment session is applied on the patient's head at least 2 days per week.

2. The method according to claim 1 wherein one treatment session is applied at least one time every 24 hours.

3. The method according to claim 1 , wherein the time T in step d) is at least 5 minutes.

4. The method according to claim 1 , wherein the time T in step d) is at most 30 minutes.

5. The method according to claim 1 , wherein an intensity of the direct current is from 0.5 to 3 mA.

6. The method according to claim 1 , wherein an intensity of the direct current is about 2 mA.

7. The method according to claim 1 , wherein the progressive increase of the direct current follows a slope of from 0.06 mA/sec to 0.6 mA/sec.

8. The method according to claim 1 , wherein T′ is 5 seconds.

9. The method according to claim 1 , wherein a density of the direct current is from 0 to 100 μA/cm 2 .

10. The method according to claim 9 , wherein the density of the direct current is from 50 to 60 μA/cm 2 .

11. The method according to claim 1 , wherein the treatment is applied during at least one week.
