Answer

Neuroimaging studies of individuals with bipolar disorder or other mood disorders also suggest evidence of cell loss or atrophy in these same brain regions. Thus, another suggested cause of bipolar disorder is damage to cells in the critical brain circuitry that regulates emotion. According to this hypothesis, mood stabilizers and antidepressants are thought to alter mood by stimulating cell survival pathways and increasing levels of neurotrophic factors to improve cellular resiliency. In 2008, Mathew et al published a review of novel drugs and therapeutic targets for severe mood disorders that focus on increasing neuroplasticity and cellular resiliency. [42]
