Many people experience mental health difficulties at some point in their lives. It's not accurate to immediately attribute this to a psychiatric illness. What are commonly referred to as "psychological illnesses" in everyday life, in medical terms, can be defined as: These illnesses affect emotions, thoughts, and behaviors, impairing a person's relationships and functioning. They can be temporary or chronic and can affect a person's daily life. Defining psychiatric illnesses can be difficult, but it's important to understand that these illnesses are often associated with mental distress and impaired functioning in various areas of life.

Psychological diseases and their causes

• Anxiety disorder: Anxiety, or anxiety disorder, is a state of intense and persistent worry beyond the usual anxieties encountered in normal daily life. This condition can interfere with daily activities and may manifest as panic attacks. Types of anxiety disorders include social anxiety disorder, separation anxiety disorder, specific phobias, and generalized anxiety disorder. Treatment may include medications, therapy, or a combination of these, depending on the type and severity of the anxiety and the individual's situation.
• Depression: Depression is a condition that impacts quality of life, reduces functionality, and is often characterized by symptoms such as anhedonia (a decreased ability to experience pleasure), persistent sadness, and hopelessness. Chemical imbalances, environmental factors, and genetic factors may play a role in the development of depression. Treatment may include psychotherapy and/or medications.
• Attention-deficit/hyperactivity disorder (ADHD): A neurodevelopmental disorder characterized by symptoms such as inattention, hyperactivity, and impulsivity, beginning in childhood. Treatment for this condition may include various therapies, education, and medications.
• Bipolar disorder: Also known as bipolar disorder, this condition fluctuates between periods of mania and depression. Symptoms include high energy, little sleep, excessive self-confidence, and risky behavior during manic periods, while symptoms include sadness, hopelessness, and apathy during depressive episodes. Medication and therapy can be used for treatment.
• Schizophrenia: A brain disorder that typically begins in adolescence and manifests itself with symptoms such as distorted perception of reality, decreased emotional expression, and social withdrawal. Medication, therapy, and social support are important in treatment.
• Post-traumatic stress disorder (PTSD): A condition characterized by long-lasting feelings of fear, terror, or helplessness following a severe trauma. This can manifest as flashbacks, nightmares, and avoidance behaviors. Therapy and support are essential for treatment.
• Eating disorders: Eating disorders are characterized by disturbances in eating behaviors and can seriously impact a person's physical health. They include anorexia nervosa, bulimia nervosa, and binge eating disorder. Treatment may include therapy, nutritional counseling, and support groups.
• Obsessive-compulsive disorder (OCD): A disorder characterized by intrusive and repetitive thoughts (obsessions) and repetitive behaviors (compulsions) to suppress these thoughts. Treatment may include psychotherapy and medication.

Treatment for each mental illness is individualized and can vary depending on the individual's situation, symptoms, and medical history. Therefore, it is important to work with a qualified healthcare professional in every situation.

How to understand psychological disorder?

While there is no specific test to diagnose psychological disorders, experts attempt to make a diagnosis by observing a person's signs and symptoms and conducting a detailed clinical assessment. The following steps can be taken during this process:

• Clinical assessment: Specialists conduct a detailed clinical assessment to understand the person's symptoms and past medical and mental health history. This may include when symptoms began, their course, their impact on daily life, and any family history.
• Physical exam: Some psychiatric disorders may be associated with physical health problems. Professionals will take steps to rule out any underlying medical conditions by performing a physical exam.
• Laboratory tests: In some cases, certain signs or symptoms may be associated with other medical conditions. Therefore, laboratory tests such as blood tests, hormone level measurements, biochemical tests, or neurological tests may be necessary.
• Psychiatric assessment tools: Scales and tests are used to diagnose specific psychiatric disorders and assess their symptoms. These tests can help assess specific symptoms and guide a diagnosis.

Diagnosis of psychological disorders is often made through a combination of methods. These methods are based on the professional's clinical experience, the patient's symptoms, physical condition, and medical history. Diagnosis of each condition is individualized, and specialists adopt a personalized approach for each patient. Therefore, it is important to seek professional help for psychiatric issues.

How are psychological illnesses treated?

Various methods can be used to treat psychiatric illnesses, and treatment is often customized to the type and severity of the illness, as well as individual circumstances. The main treatment methods include:

• Psychotherapy: This type of therapy is conducted by psychologists, psychiatrists, or therapists. Therapies that include various techniques can range from cognitive behavioral therapy, psychoanalysis, and emotionally focused therapy. It helps individuals understand, manage, and change their emotional, cognitive, and behavioral processes.
• Medication: Medications prescribed by psychiatrists can help manage the symptoms of depression, anxiety, bipolar disorder, and other psychiatric disorders. Medications such as antidepressants, antipsychotics, and anxiolytics may be used. Medication should be administered under the regular supervision of a specialist.
• Therapeutic activities: Lifestyle changes such as exercise, regular sleep, a balanced diet, and stress management can play an important role in managing psychiatric disorders. These activities can positively impact overall mood and mental health.
• Supportive therapies: Complementary and alternative therapies, such as yoga, meditation, art therapy, and music therapy, can help restore emotional balance. They can reduce stress, promote relaxation, and support mental health.
• Social support and network: Maintaining social relationships and receiving support is an important factor in coping with psychiatric illness. Seeking help from sources such as family, friends, support groups, or counseling services can support a person's recovery.
• Electroconvulsive therapy (ECT): This is a rarely used but effective treatment method in certain situations. It may be preferred, particularly in cases of severe depression and resistant bipolar disorder.

Treatment for psychiatric illnesses often requires a combination of treatment modalities and can vary for each patient. Seeking evaluation and guidance from a qualified healthcare professional is crucial in determining the most effective treatment options.

Difference between psychologist and psychiatrist

Treatment approach:

• Psychologists: Typically focus on therapy and counseling. They address emotional, mental, and behavioral issues using methods such as talk therapy and counseling sessions with individuals, couples, or groups.
• Psychiatrists: They may use both biological and psychological treatment methods. They may use psychotherapy alongside biological treatments such as medication and electroconvulsive therapy.

Psychologists and psychiatrists often work together to develop a patient's treatment plan. Psychologists provide therapeutic support, while psychiatrists may administer medication or other biological treatments. Both play important roles in mental health issues and, by working together, can help patients achieve a better outcome.
