Some issues Dr. Lars Rikardsen, MD can help you with:

Mental Health Issues

Mental health issues, also referred to as mental health disorders or mental health illnesses, are a wide variety of conditions that impact behavior, emotion, and cognition. There are many different forms of mental health issues, some of which are acute (short-term), while others are chronic. Common mental health issues include:

Anxiety disorders, such as obsessive compulsive disorder (OCD), panic disorder, and phobias
Mood disorders, such as depression and bipolar disorder
Eating disorders, such as anorexia and bulimia
Personality disorders, such as borderline and narcissistic personality disorders
Grief and trauma, such as post-traumatic stress disorder (PTSD)
Impulse control and addiction disorders
Psychotic disorders, such as schizophrenia and schizoaffective disorder

No single cause of mental health issues exists. Multiple factors may increase one's risk for developing mental health issues, including but not limited to:

Genetic history
Chemical imbalances in the brain
Traumatic brain injury (TBI)
Substance use
Exposure to viruses, chemicals, or other substances in the womb
Adverse life experiences, such as childhood trauma or recurring stress
Isolation and poor living conditions

Mental health issues are typically diagnosed by a provider like a psychiatrist or a psychologist. These issues are diagnosed through psychological evaluation and talk therapy.

Mental health therapy can be an effective tool in supporting people who are struggling with unwanted feelings, behaviors, or difficult circumstances in their lives. Many forms of therapy are available, including specialized therapies tailored to particular disorders. For many issues, therapists help patients manage their conditions through talk therapy. Other treatments can include medication or stays at a psychiatric facility. Mental health therapy can help people with mental health issues improve their mental and emotional wellbeing.
