What Is Labile Mood?

Labile mood is the clinical term for unpredictable and uncontrollable mood swings. This phenomenon is also referred to by several other terms, including emotional lability, affective lability, emotional incontinence, and pseudobulbar affect (PBA).

Labile mood is not a mental health disorder, but it can be a symptom of several psychiatric conditions. As we’ll discuss a bit later in today’s post, it can also result from a range of medical concerns as well as certain behaviors and external influences.

Common Characteristics

The key characteristics of labile mood symptoms are their abruptness, intensity, duration, and appropriateness, such as:

Sudden mood swings, which can include abruptly shifting from intense joy to deep sadness for no apparent reason
Unexpected or unprompted outbursts of laughing or crying with little warning or obvious cause
Poor emotional regulation, which means that the person is unable to control the intensity or duration of their outbursts
Excessive emotional reactions that are clearly disproportionate to whatever triggered them

Sometimes, the emotions that a person exhibits are appropriate for the circumstances, but they are more intense or last far longer than what would be considered a normal response. In other circumstances, they may be completely inappropriate, such as laughing loudly during a particularly somber moment.

Potential Effects

The outbursts and other behaviors that are associated with labile mood can have a highly disruptive impact on many parts of a person’s life.

Potential negative effects include:

Strained relationships
Problems in school or at work
Difficulty finding and keeping a job
Diminished confidence
Low self-esteem
Social withdrawal and isolation
Poor self-care

Is Labile Mood Common?

According to the book Behavior Change Interventions for Serious Mental Illness, the rate of affective lability is about 13.9% among the general public. With a current U.S. population of about 342 million people, this means that around 42 million people may develop these symptoms at some point in their lifetime.

Emotional liability is likely to be much more common within certain subgroups:

A March 2023 study in the journal Psychiatry Research found “significantly higher levels” of labile mood and affect among parents with schizophrenia or bipolar disorder, when compared with parents who didn’t have either of those conditions.
An August 2015 article in the journal CNS Drugs noted that 38%-75% of children and adolescents with ADHD exhibit labile mood.
A May 2016 study in the journal Brain Injury reported that labile affect is the most common type of personality change among children who experience severe traumatic brain injury, affecting about 49% of patients.

What Causes Labile Mood?

Labile mood has been linked to multiple mental illnesses and medical conditions. Various behaviors and experiences can also increase the likelihood that a person will struggle with emotional lability.

Mental Illnesses

Labile mood can be a symptom of mental health disorders such as:

Medical Conditions

How Can You Manage Labile Mood?

The best strategies for managing labile mood can be influenced by a host of personal factors, including the cause, type, and intensity of a person’s symptoms. But generally speaking, beneficial options include identifying your triggers, learning self-soothing techniques, practicing mindfulness, and getting professional help.

Identify Triggers

Triggers are situations and circumstances that can prompt the onset of mood swings or emotional outbursts.

The unpredictable nature of labile mood means that it’s not always easy, or even possible, to identify all potential triggers. But if you know when you’re more likely to have difficulty, such as when you’re tired, in a crowded room, or juggling multiple tasks, you can take steps to either avoid these triggers or plan ahead for how to manage your emotions.

Learn Self-Soothing Techniques

There are a range of breathing exercises and other techniques that can help you calm your mind and recenter yourself when you feel your emotions starting to get away from you.

Different people respond better to different approaches, so take the time to do some research and practice various options. When you find one that works for you, you’ll be ready the next time you find yourself on the precipice of an outburst or meltdown.

Practice Mindfulness

Mindfulness is an approach to life that encourages you to remain fully present in the moment, feeling your feelings and interacting with your environment without judgment or reflexive reaction. The practice also reminds you that feelings come and go, but you are always in control of how (or even if) you choose to respond.

Meditation and yoga are two popular mindfulness-based activities, though you can corporate this practice in every part of your life.

Seek Professional Help

Consulting with a therapist or entering a treatment program can help you understand the underlying causes that contributed to your struggles with labile mood, then learn how to manage these symptoms so you can live a more satisfying life.

Depending on your specific needs and the specialization of the professionals who help you, your treatment for emotional lability may include elements such as:
