Research shows a clear link between bipolar disorder and addiction, with data indicating that 61% of bipolar I patients experience substance use disorders in their lifetime. However, the reasons behind this connection are not straightforward. In the following sections, we will explore the intricacies of bipolar disorder and addiction, examining how each condition might exacerbate or even trigger the other.
Substance-induced bipolar disorder
Substance-induced bipolar disorder occurs when drug or alcohol use triggers manic or depressive episodes in individuals who otherwise do not exhibit bipolar symptoms previously. These mood disturbances are directly linked to substance use and typically diminish or disappear once the substance is no longer in the person’s system.
Research has found that substance-induced mood disorders often resemble their independent counterparts. For example, substance-induced bipolar disorder mirrors the symptoms of bipolar spectrum disorders. Stimulants like cocaine and amphetamines can create effects similar to bipolar disorders, including euphoria, increased energy, anorexia, grandiosity and paranoia. On the flip side, withdrawing from stimulants can lead to anhedonia, apathy, a depressed mood and even suicidal thoughts.
Self-medication leading to addiction
Addiction can often start in individuals with bipolar disorder due to the tendency to self-medicate. According to data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), which surveyed 43,093 community-dwelling adults aged 18 years and older, almost one-quarter of individuals with mood disorders (24.1%) used alcohol or drugs to relieve their symptoms. Among those with bipolar I disorder, the prevalence of self-medication was particularly high at 41.0%.
People with bipolar disorder may turn to self-medication as a way to manage the intense emotional fluctuations associated with the condition. Bipolar disorder can cause extreme mood swings, ranging from manic highs to depressive lows, often accompanied by severe anxiety. The urge to self-medicate stems from a desire to alleviate these overwhelming symptoms quickly. Alcohol and drugs can temporarily reduce feelings of anxiety, stabilise mood swings and provide a sense of relief, albeit short-lived and ultimately harmful.
The longer a person self-medicates with drugs and alcohol, the higher the chance is of forming an addiction to their choice of ‘medication’.
