Personality changes can be caused by a mental illness like depression, bipolar disorder, or personality disorders. It may also be caused by physical illnesses like a urinary tract infection (especially in older adults), concussion, or brain tumor. Understanding the cause can help create an effective treatment.
Dissociative identity disorder (DID) is a mental health condition. Someone with DID has multiple, distinct personalities. The various identities control a person's behavior at different times. The condition can cause memory loss, delusions or depression.
It has long been believed that people can't change their personalities, which are largely stable and inherited. But a review of recent research in personality science points to the possibility that personality traits can change through persistent intervention and major life events.
If you don't find effective ways to relieve stress, it can lead to changes in mood and personality. If you or someone you know is under frequent stress or has experienced a traumatic event, you may notice personality changes, such as: Withdrawal from friends and family.

According to previous studies, the correlation between anxiety and neuroticism is two times the correlation between anxiety and introverted personality traits. In this paper, we examined the relationship between personality traits, emotions and neurotransmitters related to anxious traits.
Nearly all personality disorders have some links to anxiety. Personality disorders in the anxious/fearful category are often characterized by their anxiety, and most personality disorders coincide with a severe disruption in coping ability, which in turn makes developing stress and anxiety problems much more likely.
Anxiety and personality changes can be seen in many different conditions. Examples include generalized anxiety disorder, panic disorders, bipolar disorder, depression, and dementia conditions.
Having a stroke can affect your emotions and personality. You may laugh or cry for no reason. These changes can be hard to adjust to, especially for those closest to you. Emotional and personality changes can get better with time.

A mood swing is a sudden or intense change in emotional state. During a mood swing, a person may quickly switch from feeling happy and upbeat to feeling sad, irritable, or angry.
The most prominent symptoms of MDD include a severe and persistent low mood, profound sadness, or a sense of despair. The way depression affects the brain can directly result in personality changes.
It's not clear exactly what causes personality disorders, but they're thought to result from a combination of the genes a person inherits and early environmental influences – for example, a distressing childhood experience (such as abuse or neglect).
Eventually, personality disorders characterized by a high level of neuroticism and psycho-social dysfunction, especially in relationships, such as BDP (Jovev, 2006), are associated with frequent exposure to stressors and difficulty responding to them.
From 36% to 76% of patients with anxiety disorders have been found to have a comorbid personality disorder diagnosis, with avoidant, dependent, obsessive-compulsive and paranoid being the most frequent [12].
