Understanding Mental Health Disorders: A Statistical Overview
While many individuals experience occasional periods of stress or emotional difficulty, certain mental health conditions can cause more significant changes that substantially interfere with daily functioning. Mental health disorders encompass a wide range of conditions that affect mood, thinking, and behavior. A review of the facts and figures reveals that mental health disorders represent a serious public health concern affecting diverse communities worldwide. Read on to learn more about common mental health conditions and key statistics about their prevalence globally.
What are mental health disorders?
Mental health disorders are conditions characterized by alterations in thinking, mood, or behavior that cause distress or impair functioning.
Different types of mental health disorders may affect different aspects of mental functioning, which is why symptoms can vary significantly in every individual’s journey. However, in general, common symptoms of mental health disorders include:
- Changes in mood or emotional regulation
- Difficulty with concentration or decision-making
- Changes in energy levels or sleep patterns
- Persistent feelings of worry, fear, or sadness
- Social withdrawal or isolation
Telehealth mental health services through ReachLink can provide individuals with the support they need as they address these symptoms. An individual with a mental health condition will often benefit from a care team approach, which may include a primary care provider, psychiatrist, therapist, and support network. While some mental health conditions are chronic in nature, evidence-based treatments can significantly alleviate symptoms and improve quality of life for those affected.
Types
Mental health professionals recognize several major categories of mental health disorders. Here’s a brief overview of some common types.
Adjustment disorders
If typical reactions to stressful life events progress to the point where they’re persistent and begin to affect your daily functioning, you may be experiencing an adjustment disorder. In this case, it’s typically best to speak with mental health professionals to discuss treatment options, as early intervention can prevent progression to more severe conditions.
Anxiety disorders
Anxiety disorders are the most common form of mental health condition. They are characterized by excessive worry, fear, or nervousness that interferes with daily activities. These disorders often target the body’s stress response system, affecting thought patterns, physical sensations, and behavior.
Mood disorders
Mood disorders are the second-leading cause of mental health impairment worldwide, according to recent studies. People living with mood disorders may experience persistent feelings of sadness or periods of excessive happiness, irritability, or both, that represent a significant change from their typical emotional state.
Other forms to note
Less common but significant mental health conditions include:
- Psychotic disorders, which involve distorted awareness and thinking. People with psychotic disorders typically experience symptoms like hallucinations, delusions, and disorganized thinking or speech.
- Personality disorders, which involve rigid and unhealthy patterns of thinking, functioning, and behaving that significantly differ from cultural expectations and cause problems in relationships and other areas of functioning.
- Trauma-related disorders, which develop following exposure to a traumatic event and can cause flashbacks, nightmares, severe anxiety, and uncontrollable thoughts about the experience.
Risk factors
A person living with certain risk factors may be more likely to develop mental health disorders. Key risk factors include:
- Family history of mental health conditions
- Traumatic life experiences
- Chronic medical conditions
- Substance use
- Social isolation or lack of support
- Childhood abuse or neglect
- The presence of other mental health conditions
To evaluate an individual for mental health disorders, a clinician will typically take a thorough medical and psychological history and conduct a comprehensive evaluation to eliminate other potential causes of symptoms, such as physical health conditions or medication effects. The process may also include standardized assessments, questionnaires, or other diagnostic methods to determine the nature and severity of symptoms.
