Causes
Genes may increase the chances of developing bipolar. As with many mental illnesses, genes determine how vulnerable someone might be to a condition. But environmental factors such as stress are often the triggers that are linked to its development. But these triggers do not seem to set off the development of bipolar episodes or disorder in everyone with genes for this condition. Scientists are trying to find out why.
Bipolar episodes can be triggered by:
- Substance use
Cocaine, steroids, amphetamines, hallucinogens.
- Medications
Isoniazid, steroids, disulfiram, amphetamines, cimetidine, levodopa, methylphenidate, opioids.
