Everything You Need To Know About Bipolar Disorder


At a glance:

  • Bipolar disorder (formerly known as “manic depression”) is a chronic mental condition characterised by extreme swings in mood between mania and depression
  • Mania is considered a period of euphoria and high energy during which a person may make rash and illogical decisions
  • Depression is a period of low mood, with symptoms including social withdrawal, feelings of sadness and hopelessness, as well as a loss of interest in activities
  • The cycle of these swings varies from person to person, with some people experiencing moods that last for weeks or months, and others that only last for days. 
  • The frequency of these cycles also varies from person to person
  • Around 1 in 50 Australian adults experience bipolar disorder each year
  • Bipolar disorder cannot be cured but the symptoms can be controlled or reduced with medication 

What is Bipolar Disorder?

Everybody has mood swings from time to time, but these swings in mood are usually caused by environmental or emotional stimuli. Bipolar disorder (BPD), formerly known as “manic depression” is a chronic mental health condition characterised by extreme changes in mood that can last for days or weeks at a time. A person with bipolar disorder cycles between periods of feeling very “high” or euphoric (mania) and extremely low periods (depression), often without an identifiable triggering event. 

The exact cycle of mood changes varies from person to person. In some people changes in mood can last weeks or months, and in others the mood swings are shorter and more intense.

Symptoms of bipolar disorder usually first appear before the age of 20, with most people having their first manic or depressive event between the ages of 15 and 19. As depression is often the first symptom experienced by people with bipolar disorder (only about 25% of people experience mania as their first symptom of the condition), many people are initially misdiagnosed.

Types of Bipolar Disorder

There are three recognised types of bipolar disorder, each characterised by the intensity and duration of mood changes.

Type I Bipolar Disorder

People living with Bipolar I Disorder experience extreme manic (high) periods that are long lasting and can interfere with normal function, as well as depressive periods and possibly psychosis.

Type II Bipolar Disorder

People with Bipolar II Disorder typically experience less severe manic episodes (known as hypomania) that generally only last a short while (hours or days). Depressive episodes also occur but most people with Bipolar II experience periods of stability and normal mood between manic and depressive episodes.

Cyclothymic Disorder 

This form of Bipolar Disorder is not as severe as others with the mood swings generally being shorter and less severe.

Symptoms of Bipolar Disorder 

People living with bipolar disorder experience symptoms of mania and depression at different stages of their cycle. No two manic or depressive incidents are the same but they share common symptoms.

Mania

Common symptoms of a manic episode include:

  • feeling extremely euphoric ('high') or energetic
  • Increased goal-directed behaviour or fixation on a task
  • Sleeplessness, or going without sleep to achieve goals 
  • Speaking and reacting quickly with no forethought or care for consequences
  • reckless behaviour, such as participating in unsafe sexual activity, overspending or making other rash decisions with long-lasting consequences
  • Heightened aggression and irritability
  • Unrealistic plans or other forms of irrational thinking

Depression

Common symptoms of a depressive episode include:

  • Social withdrawal 
  • A lack of interest in participating in or performing tasks or activities 
  • Prolonged feelings of sadness or hopelessness
  • A lack of appetite or interest in eating
  • Weight loss
  • Feeling of guilt or anxiety without obvious cause
  • Difficulties with concentration
  • Suicidal ideation

Psychosis

People with BPD experiencing a manic episode may also experience psychotic episodes, with symptoms including:

  • Confused thinking - frequently changing or skipping between topics, making up words, speaking in garbled or muddled sentences, speaking with odd cadence (very fast or slow) or using the wrong words to describe things.
  • Delusions – false beliefs or sensations not experienced by anyone else, such as a person believing they have special abilities or knowledge or are controlled by an outside force or agent. 
  • Hallucinations – seeing, smelling, hearing or tasting things that are not there. Many hallucinations involve hearing voices that nobody else can hear.

Mania or hypomania, depression and people with psychosis can all lead to marked changes in personality and behaviour.

What Causes Bipolar Disorder?

As with most mental health conditions, the exact cause for bipolar depression is unknown. Genetics are known to be a major contributing factor to the development of BPD, with research indicating that around 80% of cases have a genetic link. This genetic link is hereditary, with people with a direct relative (sibling or parent) having a four to six times higher chance of developing BPD than those without.

One popular theory for the genetic cause of bipolar disorder is that people with the condition may have a genetic predisposition that makes it easy for neurotransmitters like serotonin and norepinephrine to be thrown out of balance causing the changes in mood.

Environmental factors, illness and stress have also been linked to the development of bipolar disorder. Stress is not known to cause BPD but can be a contributing factor or trigger for the onset of the condition. Many people with bipolar disorder find that learning to manage stress can help then reduce the frequency or relapse.

Each person living with bipolar disorder has individual triggers that can cause a relapse of manic or depressive symptoms, but some of the more common triggers include:

  • Use of both legal and illegal drugs, including alcohol and cannabis
  • Stress in the home or office
  • Negative, impactful life events like the loss of a job, the death of a loved one or illness
  • Sleeping too little when manic
  • Sleeping too much when depressed
  • Metabolic stress from changing normal patterns (irregular eating, sleeping and physical activity)
  • Stopping the use of prescribed medication (often during a manic episode)
  • Disrupting normal rhythms - radically changing routine, sleep/wake cycles, travelling overseas and the like

Treatment for Bipolar Disorder

Bipolar disorder is a lifelong condition that cannot be cured, but through a mixture of lifestyle changes, medication and therapy, the intensity and duration of manic and depressive episodes can be reduced or controlled. 

Medication

Depending on the type and severity of bipolar disorder a person experiences, they may be prescribed a number of different medications for mood stabilisation, to help control depressive episodes (antidepressants) or to control any symptoms of psychosis that may occur (antipsychotic medications). Depending on the frequency and severity of symptoms, medications may be prescribed for long term use or for short term help.

Psychotherapy

Psychotherapeutic techniques can help a person with BPD better manage their symptoms as well as alter or avoid triggers for relapse. Cognitive Behavioural Therapy (CBT) and psycho-education can help people living with bipolar disorder to regain control of their lives through a combination of challenging negative thinking and behaviour as well as helping people better understand their mental health condition, ensure that medications are taken to schedule and learn how to self manage symptoms and potential triggers for relapse.

Lifestyle Changes

Each person living with bipolar disorder may have specific lifestyle factors that contribute to recurrences of manic or depressive episodes that can be identified with the help of a medical professional, but outside of these specific changes there are still a number of things you can do to aid in control of symptoms, including:

  • Keep a routine for both eating and sleeping, and try to maintain this routine no matter the current mood
  • Learn to recognise the onset of mood changes
  • Document your moods to help better identify triggering events or activities
  • Ask a friend or family member to aid in your treatment and management of the condition
  • Surround yourself with supportive people or contact a support network
  • Avoid drugs, both legal and illegal, including alcohol, cannabis, caffeine and nicotine
