Literature examinations found that children born of parents with intense mental illness have a one third chance of developing a severe mental illness by the time they are adults. Symptoms can start to show during their teenage years with an onset average of 25.3 ( Smith, 2019). According to Adrian me Furnham and Elizabeth Anthony ( 2010) bipolar disorder is broadly categorised as biologic and genetic.
uPeople who overuse drugs are at risk of developing bipolar disorder. While substance abuse will not cause the illness, it does worsen a person's mood and fasten the development of bipolar symptoms. Medications can also trigger the progress of a manic episode and because the use of substances can also trigger psychosis, it is required that a person detox their body from these substances before being diagnosed with bipolar disorder ( Smith, 2019)
Traumatic childhood events such as sexual abuse and neglect, can increase the risk of bipolar disorder due to the inability to process and internalise these events ( Smith, 2019). Psychological theories of aetiology involve stressful life events and failure to avoid depression which consequently leads to the dysregulation of self esteem. It is suggested that there is a connection between childhood trauma and bipolar disorder ( Furnham & Anthony , 2010
