Brief Summary:
To evaluate if transcranial magnetic stimulation can be used as a biomarker in Amyotrophic Lateral sclerosis (ALS).

Condition or disease Intervention/treatment Phase
Amyotrophic Lateral Sclerosis Drug: Perampanel Other: Placebo Early Phase 1

Detailed Description:
To measure the effect on motor threshold (MT) by transcranial magnetic stimulation (TMS) after a single dose of perampanel at two dose levels.
