Depression causes a range of emotional and physical effects that can significantly shape behavior. Someone living with depression can experience huge changes to their social life, daily responsibilities, and routine, because of how the condition affects their behavior.

Behavioral signs of depression exist on a spectrum, beginning with small signals that someone’s not feeling great and ending with severe self-neglect after a deep and chronic depression.

  • Common behavioral symptoms of depression and what causes them.

Common Depression Behavior Changes

Mental health affects behavior because it influences how you think, feel, and respond to the world around you. This holds true for depression, which can drastically change how you think and feel, and is characterized by persistent feelings of sadness and a loss of interest.[1] These emotional symptoms of depression can cause you to behave differently because of neurochemical changes in the brain.

There are also physical symptoms of depression, such as sleep disturbances and changes to appetite, which can drive other behavioral symptoms.[1] At first, these symptoms might be most noticeable with friends, in the mornings, or at mealtimes, but then slowly take over your life. 

Below, we explore some of the most common depression behavior changes.

Low Motivation

A loss of interest and motivation is a core feature of depression, as the brain no longer produces feel-good neurochemicals in the same way. This can reach the point of anhedonia, which is the name for when someone experiences almost no pleasure, enjoyment, motivation, or interest in anything.[1][2]

This can result in several behavioral symptoms, such as:

  • Not pursuing hobbies and interests that you previously enjoyed.
  • Reduced willingness to expend mental or physical effort to achieve goals and rewards.
  • Finding it hard to start tasks that require effort, including basic daily responsibilities.
  • Less interest in sex than before.
  • Turning down invitations for social events because they feel less appealing.

These changes can be confusing for people who care about you. A loss of motivation can look like laziness or even rudeness when people want to spend time with you. In fact, it comes from the brain not producing the chemical signals that normally make effort feel worthwhile.

Isolation and Withdrawal

Depression can cause you to withdraw significantly from your social circle. It could stem from a lack of motivation, as discussed above, but there are other drivers of social withdrawal when it comes to depression. 

For instance, you may feel a lack of confidence and courage to get out there into the world. It might be because depression can cause low energy and make you feel as though you’re too fatigued to see friends.[3]

Importantly, depression and isolation have what’s known as a “bidirectional” relationship. This means that they affect each other. Depression causes people to self-isolate, and being isolated can also cause depressive symptoms. This makes it especially hard to get out of the trap of withdrawal, because the longer it goes on, the urge to be alone can increase.[4] 

Self-Neglect

Experts suggest that depression is a primary predictor of self-neglect.[5] It’s strongly correlated with people finding it hard to manage their physical and mental health care needs.[5] 

Self-neglect is defined as a refusal or failure to attend to your own emotional, social, and physical needs. It might involve:[5] 

  • Living in isolation or poor conditions.
  • Poor hygiene.
  • Mismanaged medications.
  • Eating poorly and not drinking enough water.

Changes in self-care and hygiene can be incredibly difficult for people with depression, as they can be a source of shame. These changes can be caused by low motivation, as discussed above, with self-care tasks becoming overwhelming. Some people with depression may carry such terrible feelings of low self-worth that they don’t believe they deserve to be taken care of.

Self-neglect can become a behavioral health crisis if it reaches an extreme point. When someone is no longer able to take care of themselves, it’s usually a sign that urgent mental healthcare is needed.

Long-Term Impacts of Depression Behaviors

People with mild depression have less intense symptoms and fewer long-term impacts, particularly if they get treatment early. However, if depression-related behavior changes are more severe and long-lasting, there are more long-term risks to health and well-being.[6] 

People with depression are at higher risk of developing chronic diseases, such as:[6] 

  • Heart disease.
  • Chronic pain.
  • Diabetes. 

This can be due to self-neglect, or because they find it harder to access healthcare that could help detect, prevent, and treat physical health conditions early.[6] 

Due to the link between depression and social withdrawal, some people find it hard to form trusting, deep, and intimate relationships. If this persists over a long time, they may feel deeply unsatisfied and lonely in later years.

Treatment for Depression Behavior Changes

If you feel like you can’t function because of depression, it’s most likely time for professional mental health treatment. There are many options for treating changes in behavior from depression.

If your depression behaviors have gone on for a long time, your treatment may need to be a longer-term process. It can require careful work to untangle the habits and beliefs that have developed over many years, so be kind to yourself if you don’t start to feel better right away.

How Does Behavioral Health Treat Depression Behavior Changes?

A behavioral health approach focuses less on emotion and mental activity when treating mental health conditions. Instead, it emphasizes the behavioral impacts of mental health conditions like depression and attempts to reverse them. The idea is that by changing behavior, you can change how you think and feel, creating an upward spiral of positive change.

Behavioral health techniques are informed by cognitive behavioral therapy (CBT), which shares its philosophy of behavioral change.

Behavioral healthcare for depression and daily functioning may involve:[7] 

  • Behavioral activation: This technique is built around taking action first. It will invite you to do the things that depression makes hard: exercise, socializing, or household chores, for example. 

It may break tasks down into manageable steps and then invite you to rate your mood after completing them. It gradually breaks the cycle of depression behaviors and gives you evidence of your capability. Plus, mood-lifting activities then make it easier to do more of them.

  • Education: A large part of behavioral therapy is psychoeducation, which involves teaching you how behavior can affect your mental health. The idea is that by giving you the theory, you’ll have greater awareness of your choices in the future.
  • Exposure: While mainly a treatment for anxiety, exposure techniques can be useful for depression too. It might invite you to do things that you’re afraid of, in a similar way to behavioral activation, to demonstrate that they’re not as dangerous or difficult as you think.

Humanistic and Psychotherapy Approaches to Depression Treatment

You can also try talk therapies for depression, such as humanistic or psychodynamic therapy. Rather than jumping straight to behavioral changes, these therapies are known as “insight-based,” which means they help you understand yourself.

Humanistic and psychodynamic approaches don’t view depression as the result of faulty beliefs. Instead, they see it as a developmental issue. This means depression comes about because of childhood experiences and should be treated within a therapeutic relationship.[8] 

These options may be more appealing to you if you want more time to speak about your feelings in therapy. If your depression has been caused by childhood neglect or abuse, or it stems from a bereavement, it can be useful to spend more time unpacking complicated feelings. 

In psychodynamic therapy, you might explore depression as a sense of grief for the loving caregivers that you never had. Children can experience frustration and hurt because of their parents but internalize those feelings (leading to depression) because they can’t voice them. Putting them into words in therapy can be key to identifying unmet needs and false beliefs about your worthiness.[8] 

Humanistic therapy provides a therapeutic relationship based around empathy, honesty, and unconditional acceptance. This is thought to provide a unique kind of relationship, one without conditions, expectations, or judgment. This can be a fruitful setting to nurture self-acceptance and self-love, often helping people with depression develop their self-determination and a unique identity.[8]
