In the 2019 movie Joker, starring Joaquin Phoenix as Arthur Fleck, we notice a recurring pattern: he suddenly starts laughing uncontrollably at odd moments. It seems incredibly difficult to control his laughter whenever he has an outburst, either at his stand-up comedy act or on a bus.
In one scene, Arthur is entertaining a child on the bus by making funny faces, which only makes the child giggle more. The child’s caregiver asks Arthur to stop, but instead, he starts laughing uncontrollably. While Arthur tries very hard to stop and explain what is happening, he simply cannot control it. Although he takes out a note that says, "Forgive my laughter. I have a condition.", the strangers on the bus are not reassured and scowl at his behavior. If you’d like to watch the scene, check out the video below: While the movie does not name Arthur’s condition, the disorder is very much real and impacts millions of Americans every year. The neurological condition is called pseudobulbar affect, also known as PBA, and leads to uncontrollable laughing or crying outbursts. PBA is one cause of emotional lability. While we will talk about PBA more below, here’s what you need to know about emotional lability.
What Is Emotional Lability? (A Definition)Emotional lability is a rapid and intense change in a person’s emotions or mood, typically inappropriate to the setting (Posner et al., 2014). For example, a person can suddenly start crying uncontrollably because of any strong emotion, even though they do not feel sad, frustrated, or happy.
However, emotional lability can also be an over-expression of positive emotions, such as enthusiasm or energy, either disproportionate to the event or improper to the circumstance (Posner et al., 2014). One example is when a person suddenly laughs uncontrollably at a funeral or when they hear bad news. Although emotional lability is typically short, lasting minutes to hours, both the positive and negative emotions can be confusing to peers. Also, it means that a person may have little control over their emotions, even though these emotions do not have to be associated with anything specific. The term originally comes from the Latin word labilis, meaning “transient, fleeting, slippery” (World of Dictionary), which highlights the dramatic and frequent shift between emotional experiences. You can watch the short video below to learn more about emotional lability and to hear some more examples on this condition. Video: Emotional LabilityEmotional Lability in the DSM-5The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5; American Psychiatric Association, 2013) is a tool health professionals use to classify and diagnose mental health disorders.
According to the DSM-5, emotional lability is defined as the “unstable emotional experiences and frequent mood changes; emotions that are easily aroused, intense, and/or out of proportion to events and circumstances.” (p. 461) In the DSM-5, emotional lability appears as a symptom in various disorders, including:
Emotional Lability SymptomsEmotional lability is characterized by rapid and dramatic shifts in emotions, usually inappropriate to the setting in which they happen.
Here are the most common symptoms of emotional lability:
Emotional lability can negatively impact a person’s daily life and functioning. These behaviors can be confusing or embarrassing. If emotional lability symptoms interfere with daily activities for you or a loved one, it is essential to talk to a healthcare provider about treatment options. What Causes Emotional Lability?Emotional lability has been documented in many conditions, such as:
One cause for emotional lability is the pseudobulbar affect (PBA). PBA is a neurologic condition caused by damage to the nervous system, either by a neurologic disorder or brain injuries, such as traumatic brain injury, stroke, or multiple sclerosis. This condition is characterized by uncontrollable crying or laughing and happens “out of the blue'' and the exaggerated emotion does not match how you feel (Ahmed & Simmons, 2013). Arthur Fleck in Joker suffers from PBA. It is said that the movie’s director and co-writer, Todd Phillips, was inspired by PBA and even showed Joaquin Pheonix a video of someone with the same condition (Vincenty, 2020). Emotional Lability in ADHDADHD is a common psychiatric disorder characterized by inattention, hyperactivity, and impulsivity. Research studies show that children with ADHD who have high levels of emotional lability also show low tolerance to frustration, increased irritability, and frequent crying spells or tantrums (Posner et al., 2014).
Also, emotional lability in children with ADHD is associated with more severe ADHD symptoms, higher rates of substance use disorders, oppositional defiant disorder (defiant and disobedient behavior to authority figures), and affective symptoms (Sobanski et al., 2010). Emotional Lability in Borderline Personality DisorderWhile overall problems in emotional functioning characterize borderline personality disorder (BPD), emotional lability is a core trait of this disorder (Schoenleber et al., 2016). Research shows that patients with BPD have higher levels of lability of anger and anxiety than patients with other personality disorders (Koenigsber et al., 2002) and that women exhibit greater anxiety lability (Schoenleber et al., 2016).
Emotional Lability in Bipolar DisorderBipolar disorder (BD) is a disorder that leads to changes in mood, energy, and ability to function properly. A key characteristic of this brain disorder is mood swing episodes, from depressive lows to manic highs, that usually last days or weeks. A depressive mood episode means that a person is severely depressed, while a manic episode implies that the person is abnormally happy or irritable (American Psychiatry Association, 2021). These extreme mood fluctuations can have a negative impact on a person’s daily life, work, and relationships.
If you’d like to find out more about bipolar, you can watch the short TED-Ed video below and learn more about causes, symptoms, and treatment. Mood lability is not only a symptom of bipolar but also predicts Bipolar Disorder onset and is associated with psychological impairment (Hafeman et al., 2020). Although the standard treatment for Bipolar Disorder is medication, such as mood stabilizers and antidepressants, there are new and promising approaches to target mood lability--mindfulness.
Mindfulness, or intentionally, non-judgementally paying attention to the present moment, has been shown to reduce emotional lability and anxiety (Hafeman et al., 2020). Emotional Lability After Brain InjuryBrain injury refers to brain dysfunction caused by a violent external blow to the head or body. For example, many American football players have severe brain injuries due to serious and frequent hits to the head or body (Morris et al., 2020).
Emotional lability happens because of damage to the parts of the nervous system that control:
After a brain injury, one may lose emotional awareness and sensitivity, so the brain’s capacity to control emotional behavior may be impacted (Acquired Brain Injury Outreach Service, 2021). A reaction may be appropriate in a given situation, but the expression may be more intense. For example, after watching a movie where the dog dies at the end, a person with emotional lability can genuinely be sad and tearful, but once they start crying, it can become incredibly difficult to stop, and it can continue for hours without stopping. Emotional Lability TestWith almost 2 million people in the US diagnosed with PBA, this condition is pretty common. However, PBA is often misdiagnosed as depression (PBA Info). If you think you have PBA, talk to your healthcare provider.
If you’re wondering whether you or someone you know might have this condition, sudden, regular, and uncontrollable crying or laughter, you can take a short quiz. With only seven questions, this quiz can help you start a conversation about PBA. You can take the Pseudobulbar Affect Quiz here. Note that this quiz is not a diagnostic tool. Only a health professional can diagnose PBA. Emotional Lability TreatmentBeing unable to control the intensity or the expression of your emotions can not only be frustrating but also impact your daily life. For example, if you struggle with emotional lability, you may avoid going to happy hour after work or hanging out with your friends because you are worried about what could happen.
It is vital to know that you are not alone and treatment options exist.
How to Deal With Emotional LabilityIf you, or someone close to you, are experiencing emotional lability, there are a few things to do to better cope with it. Although it can be challenging to deal with emotional lability, there are a few ways to do so (Acquired Brain Injury Outreach Service, 2021).
