Bipolar Disorder: Triggers and Symptoms

Forms of Bipolar Disorder

Bipolar disorder is characterized by periods of abnormally elevated mood and energy levels, known as manic or hypomanic episodes, interspersed with episodes of depression. These mood swings can occur several times a year, or rarely. The frequency of episodes isn't as significant as the emotional shift from a low to a high mood, often accompanied by euphoria, heightened energy levels, irritability, and reckless behavior.

The Diagnostic and Statistical Manual of Mental Disorders (DSM 5) identifies at least four forms of bipolar disorder:

  1. Bipolar disorder type 1
  2. Bipolar disorder type 2
  3. Cyclothymic disorder
  4. Substance-induced bipolar disorder

Bipolar Disorder Type 1

Bipolar 1 is defined by the presence of at least one manic episode in a person's lifetime, which may be preceded or followed by a hypomanic or major depressive episode. This definition is based on the Diagnostic and Statistical Manual of Mental Disorders (DSM 5), a widely recognized diagnostic tool in the field of psychiatry.

Bipolar disorder, in general, is characterized by extreme mood swings, where individuals may experience periods of abnormally high mood (mania or hypomania) and periods of depression. The frequency and severity of these mood swings can vary greatly from person to person.

Bipolar Disorder Type 2

Bipolar 2 is characterized by recurrent episodes of major depression and hypomania, without the occurrence of full-blown manic episodes. According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), individuals with Bipolar 2 experience depressive episodes lasting for at least two weeks and hypomanic episodes lasting for at least four consecutive days.

Unlike Bipolar 1, the manic episodes in Bipolar 2 are less severe, allowing affected individuals to maintain a level of daily functioning. The distinctive feature of this disorder is the cyclic pattern of highs (hypomania) and lows (depression), impacting mood, energy levels, and overall daily functioning.

Cyclothymic Disorder

Cyclothymic disorder, or cyclothymia, is characterized by alternating periods of moderate depression and hypomanic symptoms over at least two years. The patient may experience moments of mood stability, but these never exceed two months. Mood swings usually occur suddenly and unpredictably. Cyclothymia is less severe than bipolar type 1 and type 2 disorders, as neither the depressive nor the hypomanic episodes reach the severity of major forms.

Substance-Induced Bipolar Disorder

This form of bipolar disorder involves manic/hypomanic and/or depressive episodes triggered by the intake of certain drugs or substances, or due to withdrawal syndrome. The manic and depressive symptoms must appear during or shortly after intake or withdrawal of the offending substances. Some substances that could potentially induce bipolar symptoms include alcohol, hallucinogens, amphetamines, cocaine, benzodiazepines, and certain hypnotics, sedatives, and anxiolytics.

What Causes Bipolar Disorder?

The exact cause of bipolar disorder remains unknown. However, experts suggest that it likely results from a combination of several factors:

  • Genetic Factors: A genetic or hereditary component could influence the presence of bipolar disorder. This theory emerges from the observation of the condition in people with a family history of bipolarism.
  • Biochemical Factors: Some studies have highlighted altered levels of neurotransmitters (specifically dopamine, norepinephrine, and serotonin) in the brains of people with bipolar disorder. This has led experts to propose that bipolar disorder could depend on an excess or deficiency of these neurotransmitters.
  • Environmental Factors: Environmental factors refer to any circumstance, event, or habit that can significantly affect an individual's life. Traumatic experiences or long periods of stress could potentially trigger bipolar disorder, especially in those with a genetic or biochemical predisposition.

Typically, bipolar disorder first appears in late adolescence or early adulthood, but can occur at any time throughout a person's life. The exact cause of bipolar disorder remains unknown. However, several factors have been identified that may increase the likelihood of developing the condition. These include genetic predisposition, stressful life events, imbalances in neurotransmitters such as serotonin and norepinephrine, and psychosocial factors. Certain medications can also trigger episodes in individuals with bipolar disorder.

Symptoms of Bipolar Disorder

The symptoms of manic and hypomanic episodes are similar but more pronounced in manic episodes. They include excessive happiness, abnormal optimism, high self-esteem, extreme talkativeness, poor judgment, quick thinking, agitated behavior, excessive physical activity, unusual desire to achieve certain results, diminished need for sleep, tendency towards distraction, and inability to concentrate properly.

Depressive symptoms can significantly affect social and romantic relationships, work, and school. They include sadness, lack of hope, irritability, loss of interest in enjoyable activities, weight changes, sleep disorders, lethargy, feelings of worthlessness or guilt, restlessness, fatigue, slowness in activities, feelings of banging for no reason, concentration problems, and suicidal thoughts.

The Manic Phase

During a manic episode, individuals may experience a persistent elevated mood, extreme euphoria, hypersensitivity, agitation, decreased need for sleep, and increased talkativeness. Their thoughts may race, and they may be easily distracted. They may also display an inflated self-esteem and engage in risky behaviors without understanding the potential harm. In severe cases, individuals may experience manic psychosis, which can include symptoms such as delusions of grandeur, persecutory delusions, and visual or auditory hallucinations.

The Depressive Phase

Depressive episodes in bipolar disorder share many characteristics with major depression. Symptoms can include profound sadness, lack of energy, anhedonia (the inability to feel pleasure), psychomotor slowing, feelings of guilt, changes in sleep patterns, and appetite disturbances. Individuals with bipolar disorder are also at a significantly increased risk of suicide, and the disorder can be further complicated by substance abuse.

Treatment of Bipolar Disorder

Bipolar disorder is a lifelong condition. However, with appropriate treatment, it is possible to significantly limit the symptoms and potential complications. Treatment typically involves psychotherapy techniques, medication for mood changes and depression, and management of any addictions.

Psychotherapy techniques that can be beneficial include cognitive-behavioral therapy, interpersonal therapy, interpersonal and social rhythms therapy, and family-focused therapy.

Medications used for the management of bipolar disorder can include mood stabilizers, antipsychotics, and antidepressants.

Additionally, lifestyle changes such as regular physical activity, maintaining a regular sleep schedule, and avoiding alcohol and drugs can also be beneficial for individuals with bipolar disorder.

In conclusion, bipolar disorder is a complex mental health condition that requires comprehensive treatment and management. By understanding the condition individuals can better navigate the challenges associated with this disorder. If you or someone you know is experiencing symptoms of bipolar disorder, seek professional help immediately. Remember, there's no shame in reaching out for support when you need it.
