In Mental, Jaime Lowe shares and investigates her story of episodic madness, as well as the stability she found while on lithium. She interviews scientists, psychiatrists, and patients to examine how effective lithium really is and how its side effects can be dangerous for long-term users — including Lowe, who after 20 years on the medication suffers from severe kidney damage. Mental is eye-opening and powerful, tackling an illness and drug that has touched millions of lives and yet remains shrouded in social stigma.
