Yes, depression can significantly alter behavior, mood, and thinking patterns, leading to changes that appear to be personality shifts, such as increased irritability, withdrawal, or negativity, though core personality traits might not fundamentally change but rather become obscured or exaggerated by the illness. While some studies suggest typical episodes don't cause lasting personality changes, severe, chronic, or recurrent depression can affect brain function and lead to behavioral changes like loss of interest (anhedonia) or heightened emotional reliance, mimicking personality alterations over time.
The duration of depression can vary greatly depending on several factors. Typically, an untreated depressive episode can last about 6 months or longer. However, with effective treatment, the duration can be significantly reduced.

The person who has depression may also have a manipulative personality. And this combination of depression and manipulative behaviors can be especially difficult for anyone who is trying to help, whether it is the person's therapist, family members, spouse, or friends.
Current evidence suggests that depression is linked to traits such as neuroticism/negative emotionality, extraversion/positive emotionality, and conscientiousness.
New evidence shows that people who maintain a range of healthy habits, from good sleep to physical activity to strong social connections, are significantly less likely to experience depression.

Depression can also involve other changes in mood or behavior that include:
“Even if I'm not able to understand exactly how you feel, I care about you and want to help.” “You're important to me. Your life is important to me.” “When you want to give up, tell yourself you will hold on for just one more day, hour, or minute—whatever you can manage.”

Medical conditions: Chronic pain and chronic conditions like diabetes can lead to depression. Medication: Some medications can cause depression as a side effect.
Some people who have severe depression may also experience hallucinations and delusional thinking, the symptoms of psychosis. Depression with psychosis is known as psychotic depression.
These changes in personality and behavior can be caused by general medical conditions or mental health issues. People may have more than 1 type of change. For example, people with confusion due to a medication interaction sometimes have hallucinations, and people with mood extremes may have delusions.
