Mood Disorder vs Personality Disorder
Comparing Mood and Personality Disorders
Table of Contents
ToggleDo you have a mental health problem and are unsure whether it is a mood disorder or a personality disorder? People are often confused by the two, largely due to factors like overlapping symptoms. This can lead to issues like misdiagnosis.
Icarus Wellness and Recovery provides diagnostic services and effective treatment for both mood disorders and personality disorders, alongside other mental health conditions. Our providers know how to scope out the distinguishing traits of the concerns we work with.
Let’s take a look at mood disorder vs. personality disorder symptoms, treatment options our accredited facility offers, and other differentiating factors.
Mood Disorder vs Personality Disorder
Mood and personality disorders are two different entities within the field of mental health. While both can lead to significant psychological distress, they have distinct causes and characteristics that set them apart.
Mood Disorders
Mood disorders are a group of mental health conditions that primarily affect your emotional state. These disorders can range in severity. A person’s symptoms will depend on the type of mood disorder they have.
Symptoms of mood disorders may include intense feelings of sadness, despair, difficulty sleeping and concentrating, suicidal thoughts or behaviors, fatigue, loss of interest in activities once enjoyed, and changes in appetite.
Mood disorders can fluctuate, and some come with specific patterns. Personality disorders tend to be stable and enduring.
Personality Disorders
Personality disorders involve deeply rooted patterns of thinking, feeling, and behaving that are different from the norms of a culture and cause distress to the individual or those around them. These patterns are often rigid and hard to change.
Personality disorders affect around 9.1% of individuals in the US per year. They are usually treated with talk therapy.
Personality Disorders: Traits and Clusters
A personality disorder is a type of mental illness diagnosed based on personality traits and behaviors. Specifically, enduring patterns of behaviors that cause long-term difficulty in functioning and building or maintaining interpersonal relationships.
Personality disorders are typically divided into three categories: Cluster A (odd/eccentric personality disorders), Cluster B (dramatic/emotional personality disorders), and Cluster C (anxious/fearful personality disorders). Each cluster has different characteristics.
Cluster A
Cluster A personality disorders are characterized by symptoms that appear unusual or odd to others. People with these conditions may have difficulty forming relationships.
Cluster B
Cluster B personality disorders are often marked by intense emotions and dramatic, erratic, or irrational behaviors. Symptoms displayed can be destructive or inappropriate in social situations.
Cluster C
Cluster C personality disorders involve anxious, fearful, or inhibited behaviors. Like other personality disorders, they can affect social relationships and other parts of life.

Reviewing Differences in Mental Health Disorders
Understanding the discrepancies between mood and personality disorders can be important. If left untreated, both can have serious effects. With proper treatment, people can achieve better mental health and a higher quality of life.
Common Mood Disorders and Their Symptoms
Below are some of the most common mood disorders. Next to anxiety disorders, mood disorders are some of the most frequently seen mental health conditions across the globe.
Major Depressive Disorder
Major depressive disorder (MDD) is one of the most common mood disorders. MDD involves symptoms of sadness, loss of interest in activities, and decreased energy. These symptoms last for at least two weeks and interfere with daily life activities.
Also known as major depression, depression symptoms seen in MDD are generally best treated via medication and psychotherapy.
Bipolar Disorder
Bipolar disorder is a chronic mood disorder characterized by noticeable changes in mood, energy, and behavior that affect daily life functioning. Bipolar disorder involves alternating episodes of mania and depression:
- Manic episodes are characterized by symptoms like an elevated or irritable mood, racing thoughts, decreased need for sleep, grandiose ideas, and reckless behavior.
- During depressive episodes, people can feel sad, hopeless, or lose interest in activities they usually enjoy.
There are different types of bipolar disorder. You’ll most often hear about bipolar I and bipolar II disorder. Treatment for bipolar disorder includes medication management (usually, mood stabilizers and antipsychotics) and psychotherapy.
Persistent Depressive Disorder
Persistent depressive disorder (PDD) is a more mild form of depression, but symptoms last for at least two years. Signs may include sadness or hopelessness, difficulty concentrating, difficulty making decisions, fatigue, and low self-esteem.
Treatment options for PDD, formerly known as dysthymic disorder, include psychotherapy and medications, such as antidepressants.
Seasonal Affective Disorder
Seasonal affective disorder is a type of MDD with seasonal patterns. People with seasonal depression have depressive episodes, which can be severe, during specific seasons. For example, Winter or Summer.
Premenstrual Dysphoric Disorder
Premenstrual dysphoric disorder (PMDD) involves potentially severe depressive symptoms that occur during the luteal phase and dissipate around the time your period starts. PMDD can be debilitating. It is not synonymous with PMS.
Postpartum Depression
Postpartum depression is a mood disorder that can develop following the birth of a baby. Symptoms include, but aren’t limited to, sadness, loss of pleasure in activities, difficulty sleeping or concentrating, restlessness, and irritability.
It’s estimated that up to around 15% of people experience postpartum depression after giving birth. Treatment for postpartum depression typically involves therapy, antidepressant medication, or a combination of both.
What are the Distinguishing Features of Personality Disorders?
All personality disorders have unique symptoms that set them apart from one another. Self-awareness can be a crucial part of symptom management.
Paranoid Personality Disorder
Paranoid personality disorder is characterized by extreme mistrust of other people and suspicions that others are out to harm them. People with this personality type often misinterpret the actions or intentions of those around them, leading to intense feelings of paranoia and hostility.
Symptoms can include excessive suspiciousness, holding grudges for long periods of time, difficulty trusting others, and a tendency to blame others for their problems.
Schizoid Personality Disorder
Schizoid personality disorder is characterized by extreme social detachment. People with this personality disorder often avoid intimate relationships and prefer solitary activities. Symptoms can include limited emotional expression, a lack of interest in close relationships, and an indifference to criticism or praise.
The key factor that distinguishes this condition from other mental health and neurodevelopmental disorders is that people with schizoid personality disorder don’t want or desire close relationships.
Antisocial Personality Disorder
Antisocial personality disorder (APD) is another type of personality disorder. If you have APD, you may have a disregard for the rights of others, a lack of empathy, and impulsivity. People with this disorder often engage in criminal behavior such as theft or vandalism and may be aggressive towards others.
Symptoms can include lying, manipulation of others, impulsivity, and a disregard for the safety of oneself or others.
Borderline Personality Disorder
People with borderline personality disorder (BPD) exhibit intense emotional instability and impulsive behavior. Those with BPD often act erratically in their relationships with others, leading to frequent arguments and conflicts.
Symptoms can include anger problems, self-harm or self-destructive behaviors, severe mood swings, recklessness or impulsivity, and an intense fear of abandonment. It’s often treated via a type of therapy called dialectical behavior therapy.
Histrionic Personality Disorder
Histrionic personality disorder is characterized by excessive emotionality and attention-seeking behavior. Symptoms can include overly dramatic or seductive behavior, an excessive need for approval, and difficulty forming meaningful relationships.
Schizotypal Personality Disorder
Schizotypal personality disorder is marked by eccentric behavior, odd beliefs, and social anxiety. People with this condition tend to feel intense distress in social situations and may struggle to make friends.
Avoidant Personality Disorder
Avoidant personality disorder is characterized by extreme social inhibition and feelings of inadequacy. People with this condition often have low self-esteem and avoid social situations due to their fear of being judged or rejected, even if they desire close relationships.
While anxiety can come with similar symptoms, APD is not the same as social anxiety disorder. However, it is possible to have both an anxiety disorder and a personality disorder.
Narcissistic Personality Disorder
When someone has narcissistic personality disorder (NPD), they have an exaggerated sense of self-importance. Those with NPD may have an intense need to impress others and feel important.
Entitlement, willingness to exploit others, envy, lack of empathy, and fantasies about power and success are common symptoms.
Obsessive-Compulsive Personality Disorder
You may have heard of OCD (obsessive-compulsive disorder). This is not the same as obsessive-compulsive personality disorder, or OCPD.
OCPD is a personality disorder diagnosis involving an intense occupation with perfectionism, orderliness, or control. The condition is marked by a pervasive pattern of personality traits the person may not see as problematic.
Dependent Personality Disorder
Dependent personality disorder is characterized by fear of separation and an excessive need to be taken care of. People with this personality type often rely on others to make decisions for them and may be passive or submissive so as to avoid conflict.
