Frequently Asked Questions
Bipolar disorder is primarily caused by a combination of genetic factors, as it tends to run in families, and biological factors, such as imbalances in brain chemicals that regulate mood. Environmental stressors, traumatic events, and major life changes can also trigger or worsen episodes of mania or depression in those predisposed to the disorder.
Bipolar disorder affects approximately 1 in 150, or about 40 million, people worldwide.
Through evidence-based individual therapy, facilitated group therapy, medication management, and a non-judgemental environment, Overstory’s programs treat bipolar disorder.
An Intensive Outpatient Program (IOP) can help treat bipolar disorders by providing structured treatment with multiple weekly sessions, focusing on individual therapy, group support, and skills development. It offers a more intensive level of care than regular outpatient therapy but allows participants to live at home and continue with daily activities.
A Partial Hospitalization Program (PHP) helps with bipolar disorders by providing intensive therapy and support, including individual and group sessions, to address symptoms, improve coping skills, and promote stabilization. It offers a structured environment during the day while allowing individuals to return home in the evenings, promoting recovery without the need for 24/7 inpatient care.
Everyday challenges are temporary stressors or difficulties that can cause frustration or sadness but typically resolve over time, whereas bipolar disorder involves persistent, intense emotional disturbances like prolonged sadness or extreme mood swings that significantly interfere with daily functioning and last for weeks or longer.
Duration in Overstory’s programming will depend on the individual but is expected to last two to six weeks.
