rTMS Alone followed by rTMS+AMA
AMA Alone followed by rTMS+AMA
Subjects assigned to rTMS Alone will receive 30 sessions of rTMS. Two rTMS sessions will be provided per day, four days per week.After first completing rTMS Alone, subjects will receive rTMS plus Amantadine. A total of 30 rTMS sessions are provided, 2 rTMS sessions per day, four days per week, while receiving 200mg of Amantadine daily.
Subjects who are assigned to the Amantadine Alone group will receive 28 doses of Amantadine (100mg BID) every day for 28 days. After first completing Amantadine Alone subjects will receive rTMS plus Amantadine. A total of 30 rTMS sessions are provided, 2 rTMS sessions per day, four days per week, while receiving 200mg of Amantadine daily.
