Brain Chemistry
Imbalances in neurotransmitters (chemical messengers in the brain) such as dopamine, serotonin, and norepinephrine are thought to play a role in Bipolar Affective Disorder. Structural and functional changes in the brain may also contribute to the development of the disorder.
Genetics
More than two-thirds of people with Bipolar Disorder have at least one close relative who also has the illness, suggesting a genetic component. However, having a family history of Bipolar Disorder doesn’t guarantee that you will develop the condition. Instead, it increases the likelihood of developing it.
Epigenetics
Your genes aren’t the whole story. Epigenetics looks at how stress, environment, and life experiences can switch certain genes on or off without changing your underlying DNA. This helps explain why two people with a similar genetic risk can have very different outcomes.
Environmental Triggers
Stressful life events, such as trauma, loss, or major life changes, can trigger the onset of Bipolar Disorder in susceptible people. Additionally, substance abuse, particularly drugs such as cocaine, ecstasy, or amphetamines, can worsen or trigger episodes of mania or Depression. In some cases, overlapping symptoms with Anxiety can also complicate the clinical picture.
Hormonal Changes
Imbalances in hormones can trigger or cause Bipolar Disorder. Dysregulation in hormones such as cortisol (stress hormone) has been linked to mood swings and emotional instability. Additionally, fluctuations in thyroid hormones are linked to spikes in energy and mood. It is crucial to balance hormones and neurotransmitters in the brain for an effective, long-lasting treatment of bipolar Affective disorder.
Risk Factors of Bipolar Disorder
Some factors don’t cause Bipolar Disorder outright, but they raise your chances of developing it.
Childhood Trauma
If you experienced abuse, neglect, or other significant trauma growing up, your risk of developing Bipolar Disorder later in life goes up.
Family History
Having a parent or sibling with Bipolar Disorder increases your own risk, even though it’s far from a certainty.
Gene Changes
Specific gene variations have been linked to a higher likelihood of developing the condition, particularly when combined with environmental stress.
