Answer:
Lithium carbonate
Explanation:
Bipolar disorders, which used to be called manic depression, is a serious illness that causes a person to have dramatic shifts in emotions, mood, and energy levels: moving from extreme lows to extreme highs.
But these shifts don't happen moment to moment, they usually happen over several days or weeks.
Bipolar disorders are most effectively treated with a combination of tricyclic antidepressants and lithium carbonate.
As a result, the correct answer is "lithium carbonate".
