Traits-That-Increase-the-Risk-of-Bipolar-Disorder

1. Biological Causes Of Bipolar Disorder

Research [mfn] Rowland, T. A., & Marwaha, S. (2018). Epidemiology and risk factors for bipolar disorder. Therapeutic advances in psychopharmacology, 8(9), 251–269. https://doi.org/10.1177/2045125318769235 [/mfn] attributes the common biological causes of bipolar disorder to the following factors:

I. Genetics

Studies show that monozygotic concordance and incidence of bipolar disorder amongst first-degree relatives elevate the risk of bipolar disorder by 40–70% [mfn] Rowland, T. A., & Marwaha, S. (2018). Epidemiology and risk factors for bipolar disorder. Therapeutic advances in psychopharmacology, 8(9), 251–269. https://doi.org/10.1177/2045125318769235 [/mfn].

II. Brain structure and functioning

Research shows that one of the common causes of bipolar disorder involves structural and functional changes in the brain. Dysfunctions in certain brain regions [mfn] Clark, L., & Sahakian, B. J. (2008). Cognitive neuroscience and brain imaging in bipolar disorder. Dialogues in clinical neuroscience, 10(2), 153–163. https://doi.org/10.31887/DCNS.2008.10.2/lclark [/mfn] increase susceptibility to bipolar disorders, such as :

  • Overactivated ventral system
  • Underactivated dorsal system
  • Synaptic pruning dysfunction
  • Dysregulation of dopamine and serotonin receptors
  • Decreased activity in the lingual gyrus

III. Prenatal factors

Prenatal viral infections [mfn] Barichello, T., Badawy, M., Pitcher, M. R., Saigal, P., Generoso, J. S., Goularte, J. A., Simões, L. R., Quevedo, J., & Carvalho, A. F. (2016).

Studies specifically link maternal influenza infection and T. gondii infection as common causes of bipolar disorder. Moreover, pregnancy stress and lifestyle habits like maternal substance use (tobacco, alcohol, antidepressants, and recreational drugs) are also associated with bipolar disorder.

IV. Other medical illnesses

A range of chronic physical illness, neurological conditions, and brain injury [mfn] Forty, L., Ulanova, A., Jones, L., Jones, I., Gordon-Smith, K., Fraser, C., Farmer, A., McGuffin, P., Lewis, C. M., Hosang, G. M., Rivera, M., & Craddock, N. (2014). Comorbid medical illness in bipolar disorder. The British journal of psychiatry : the journal of mental science, 205(6), 465–472. https://doi.org/10.1192/bjp.bp.114.152249 [/mfn] are associated with the onset of bipolar disorders. These include:

  • Stroke
  • Traumatic brain injury
  • HIV infection
  • Multiple sclerosis
  • Porphyria
  • Temporal lobe epilepsy
  • Irritable bowel syndrome (IBS)
  • Asthma
  • Obesity

L., Cloninger, C. R., & Soares, J. C. (2008). Temperament and character traits in patients with bipolar disorder and associations with comorbid alcoholism or anxiety disorders. Journal of psychiatric research, 42(7), 569–577. https://doi.org/10.1016/j.jpsychires.2007.06.004 [/mfn] and temperaments:
