Although the symptoms of persistent genital arousal disorder/genito-pelvic dysesthesia (PGAD/GPD) can have negative impacts on patients' lives, it is an under-recognized clinical entity. We describe the case of a 61-year-old Japanese female who suffered simultaneously from bipolar disorder and PGAD/GPD. She developed PGAD/GPD approx. 10 years after being diagnosed with bipolar disorder. Despite 20 years of various drug treatments, her bipolar disorder and PGAD/GPD symptoms showed little improvement. She had also undergone multiple sessions of cognitive behavioral therapy (CBT) and mindfulness, nerve block, botulinum toxin injections, and laser treatment for PGAD/GPD. Her PGAD/GPD symptoms remained with no significant improvement, and her bipolar disorder symptoms had also not responded well to medication. With the administration of brexpiprazole, she achieved remission of her bipolar disorder. Her PGAD/GPD symptoms also eventually improved. When PGAD/GPD is comorbid with bipolar disorder, the improvement of bipolar disorder may also lead to relief of PGAD/GPD symptoms. This case reveals that brexpiprazole, which has a unique profile, may be effective for PGAD/GPD.
