Personality Changes: Causes & Treatment

Personality Changes Symptoms

Recognizing the symptoms of personality changes is crucial for early intervention and management. Common symptoms include:

• Uncharacteristic Behavior: Notable deviations from usual behavior patterns.
• Mood Swings: Frequent and intense changes in mood.
• Difficulty in Relationships: Increased conflict or withdrawal from social interactions.
• Impulsive Actions: Engaging in risky or uncharacteristic behavior without forethought.
• Cognitive Changes: Alterations in thinking patterns or perceptions.

Extreme Personality Changes

Extreme personality changes can be particularly alarming and disruptive. These may manifest as:

• Severe Emotional Instability: Extreme fluctuations in emotional states.
• Aggressive Behavior: Increased irritability or aggression towards others.
• Paranoia or Delusions: Persistent, irrational beliefs or suspicions.
• Withdrawal: Significant withdrawal from social interactions and activities.

Causes of Personality Changes

Traumatic Brain Injury (TBI)

Traumatic Brain Injury can lead to personality changes due to physical damage to the brain.

• Bleeding in the brain: This can occur as a result of the spontaneous rupture of a blood vessel.
• Loss of oxygen in the brain: This can be due to drowning, heart attack, carbon monoxide poisoning, or other forms of suffocation. The damage occurs after a few minutes and will be evident once the person is conscious again.
• Diabetes side effects or blood sugar problems: Insufficient blood sugar, often in people with diabetes, robs the brain of energy.
• Infections: Viral and bacterial infections of the brain and spinal cord (meningitis)can cause serious damage to these tissues.
• Unconscious: Sometimes, after a hard blow to the head, behavior and personality change, especially if you pass out.

A Progressive Disease Affecting the Brain

Diseases that gradually affect the brain can cause personality changes of varying severity and onset.

• Neurological diseases: Most of them are genetic. These are known to produce profound personality changes due to their powerful effect on the brain.
• Ageing and Illness: The gradual loss of brain function due to aging, combined with unknown factors, can sometimes lead to severe disability.

Psychiatric Illnesses

Despite the complexity of these illnesses, clinicians can typically diagnose them after consulting the Diagnostic and Statistical Manual of Mental Disorders. These diseases can lead to disturbing or inexplicable behaviors due to chemical imbalances in the brain. Behavior changes can also result, affecting sleep patterns, food cravings or appetite, as well as sexual behavior in addition to mood.

Normal Aging

Normal aging can cause irritability, anger, and frustration due to:

• Hearing loss
• Loss of vision
• Loss of mobility
• Chronic pain

Rare and Unusual Causes

A brain tumour can cause the loss of some functions due to crowding and displacement of tissues, but personality change does not always occur.

Personality Changes Reasons

Various factors can contribute to personality changes, including:

• Genetic Predisposition: Inherited traits or predispositions to mental health conditions.
• Environmental Factors: Stressful or traumatic life events.
• Biological Factors: Changes in brain chemistry or function.
• Lifestyle Factors: Effects of lifestyle choices such as substance use or lack of self-care.

Diagnosis of Personality Changes

If you've been through a personality change, talk to your healthcare professional. Make sure to note:

• When the personality change started
• What time of day you experience it
• What triggers it
• If this happens after taking prescription medicine (bring the medicine with you)
• If you take drugs
• If you drink alcohol
• If you have a history of mental health problems
• If your family has a history of mental health problems
• Any other symptoms you may be experiencing
• If you have any underlying medical conditions
• The answers to these questions will be extremely helpful to your healthcare professional
• They will help you diagnose the cause of your unusual behavior. They will also help your healthcare professional determine if this is a mental health problem or a medical problem.
• They can choose to order tests.
• Tests may include a complete blood count, a glucose level test, a hormonal profile, and tests for infections
• Depending on the circumstances, your healthcare professional may also order imaging tests such as a CT scan or MRI.
• Your doctor may refer you to a psychological specialist if you don't have any apparent medical concerns.

Treatment for Personality Changes

Effective treatment for personality changes depends on the underlying cause and may include:

• Psychotherapy: Counseling or therapy to address emotional and behavioral issues.
• Medication: Prescribed drugs to manage symptoms associated with underlying conditions.
• Lifestyle Changes: Implementing healthier habits and stress management techniques.
• Support Groups: Engaging with others experiencing similar issues for support and shared experiences.

When to Visit a Doctor?

People who show warning signs should be seen by a healthcare professional as soon as possible. Law enforcement may need to be called in if people are violent.

People who have no warning signs should see a doctor within a day or two if the change in personality or behaviour is recent. If the change has occurred gradually over a period of time, people should see a doctor as soon as possible, but a delay of about a week is not harmful.
