Neurosis: Definition, Symptoms, Causes, and Treatment

Neurosis is characterized by obsessive thinking, anxiety, distress, and a certain level of dysfunction in everyday tasks. Neurotic behavior is the result of a neurosis or neuroticism. While research in this area is lacking, one study in Xi’an, China, found an estimated lifetime prevalence of 10.8% for any neurotic disorder. Specific phobias (5.7%), obsessive-compulsive disorders (3.8%), and social phobias (1.3%) were among the most prevalent subtypes.

Neurosis vs. Anxiety

Of all the diagnoses you can find in the American Psychiatric Association’s Diagnostic and Statistical Manual, 5th Edition (DSM-5), neurosis isn’t one of them. “Neurosis” became a footnote in the 1970s in the DSM-3 version, and was then removed entirely in the next revisions.

Being neurotic is associated more with being a worrier or an overthinker rather than a mental disorder. Still, without some help, neuroticisms that are surrounded by unhealthy coping mechanisms and high-stress environments may lead to anxiety disorders.

Anxiety disorders may include: 

  • Separation anxiety disorder 
  • Generalized anxiety disorder
  • Specific phobia
  • Social anxiety disorder
  • Panic disorder or panic attack disorder
  • Substance- or medication-induced anxiety disorder 


If you’re wondering if you have neurosis, ask yourself if you’ve ever experienced any of the following symptoms or traits:

  • Anxiety and apprehension 
  • Excessive worry and guilt
  • Tendency toward more negative emotions and reactions
  • Irritability and anger
  • Low self-esteem and self-consciousness
  • Poor response to stressors
  • An interpretation of everyday situations as threatening
  • Depression
  • Emotional instability

If you’re concerned that a friend or family member may have neurosis, here’s what to watch for:

  • Constantly needing reassurance (even on small matters and things you’ve previously validated)
  • Being overly dependent on others or codependent in relationships 
  • Making their dissatisfaction or stress well known to you 
  • Conflicts with others due to a lack of emotional resilience or ability to bounce back 
  • Perfectionist tendencies or obsessing about getting things right
  • Flying off the handle whenever you try to have a serious conversation 

Of course, these symptoms don’t necessarily mean your loved one is neurotic. But if it’s a pattern of behavior over time and it’s causing them distress, you should encourage them to seek help from a mental health professional. 


Left untreated, neurosis can grow into bigger health concerns for you and your relationships. This is because being neurotic takes a toll on your mental health and ability to function in everyday life.

Physical complications over time may include:

Neurosis can also lead to other health complications, including:

  • Perceived and actual marital issues (marital dissatisfaction)
  • Decreased work performance and occupational failure
  • Increased vulnerability to conditions like eating disorders, mood disorders, and use disorders to try to cope with the emotional instabilities of neuroticism


Researchers have identified an association between neuroticism and mental disorders and lower quality of life, but have not pinpointed its exact cause. Several factors are believed to be at play in the development of neuroticism.


People who have a family history of neuroticism may be more likely to have it. The evidence that shows this includes:

  • Twins studies suggesting overlap of genetic factors between different traits in neuroticism, along with other anxiety disorders.
  • The G72 gene, which plays a role in glutamate functioning (the neurotransmitter responsible for proper brain functioning), has also been associated with neuroticism, but these findings are not consistent.
  • Genetic studies on neuroticism have found a small but noteworthy difference in one of the serotonin transporter genes associated with emotion processing.


Both shared environments (common to family members) and nonshared environments like a child’s individual classroom are associated with the likelihood of developing neurotic traits.

One large-scale twins study of over 3,330 Dutch twins found that shared environments were insignificant compared with nonshared environments in predicting future neurotic behavior, meaning things that happen outside your home may have a bigger impact. However, this has been explained more so by the gene-environment interactions than the conclusion that shared environments have no impact.

Mental health conditions associated with neurotic behavior include:


If neurotic behavior is becoming a problem, you can talk to your family doctor or a mental health professional. Your doctor will likely conduct a physical exam and request lab work to determine the cause of your symptoms. 

While you will not get a diagnosis of neuroticism, you may be diagnosed with a mental health disorder if the behaviors are causing severe distress and relationship issues.


If the neurosis is stemming from an underlying mental disorder, you and your healthcare team will discuss the best treatments for that diagnosis.


Your family doctor or psychiatrist can prescribe the appropriate medications to help reduce symptoms associated with disorders like anxiety, depression, and others. Medications work to help change the brain chemistry behind neurotic behavior.

Common medications prescribed for mental disorders associated with neuroticism include:

  • Anti-anxiety medications work to reduce anxiety and associated symptoms like nervousness or restlessness. One commonly prescribed example is benzodiazepine, which is fast-acting, but people can build up a tolerance to it. 
  • Antidepressants like selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors can be used for managing the symptoms of depression.


Various forms of talk therapy, including cognitive behavioral therapy, can help address negative thought patterns and help a person work to change unhealthy ways of coping. It can also be useful for helping a person identify their neurotic behaviors and how those behaviors are contributing to other problems they’re facing.

Lifestyle Changes

Coping with your own neurotic behavior can be tiring. Practicing self-awareness and recognizing what can trigger these behaviors are critical and ongoing steps in managing neurosis. Once you know what makes your neuroticism worse, you can make some or all of the following positive lifestyle changes to support your mental health:

  • Create a “no” list: Lists can help you set boundaries throughout the day when things come up that are stressful. If you’re unsure how to proceed and are obsessing about what to do, check the list.
  • Be proactive about triggers: For example, if you know staying up later than usual too many times a week is almost always followed by an increase in symptoms or neurotic behaviors, make routine sleep times a top priority.
  • Practice breathing exercises: They help counter anxiety-related shallow breathing that deprives your body and brain of oxygen, which can then progress to full-blown anxiety or panic attacks.
  • Download a meditation or sleep story app: These can help guide you through stressful times and promote better sleep. Use apps that let you track mindfulness, write notes, or document mood so you can see your progress over time.


Neuroticism is not a mental disorder but a personality trait. It’s characterized by obsessive thinking and anxiety. Sometimes it can contribute to the development of a mental disorder like an anxiety disorder, though. It’s not something you can cure, but you can reduce neurotic behaviors by learning and managing your triggers and developing healthy ways to cope with daily stress.

Frequently Asked Questions

What’s the difference between neurosis and psychosis?

Neurosis is a personality trait, whereas psychosis is a symptom that affects the way your brain processes information. In a psychotic episode, you can hear, see, and believe things that are not real and lose touch with reality. 

How do you cure neurosis naturally?

You can’t really cure a personality trait, but you can learn to manage it by becoming aware of what triggers your behavior, such as high-stress environments or feeling out of control, and what makes your symptoms worse. Then you can address those issues directly and reduce neurotic behaviors.

There is no specific diet for people with neurosis, but the link between nutrition and mental health is well known: What you eat feeds the way you feel. This is largely because the majority of serotonin, a neurotransmitter critical for emotions, is produced in your gastrointestinal tract. Add more fresh, colorful foods to your plate and consider talking to a dietitian to come up with a healthy diet.

A Word From Verywell 

Some people have more neurotic tendencies than others, and it doesn’t mean anything is wrong with you. It’s not a mental disorder. However, if you start feeling like your neuroticism is taking over or has more control over your moods than you do, it’s time to talk to someone. Addressing the cause of your behavior can help you make impactful changes and manage these personality traits so they don’t interfere with your daily life.
