Mental Illness: What You Need To Know
Types of Mental Illness
Mental illness encompasses a wide range of conditions that affect mood, thinking, and behavior.
-
Mood Disorders impact emotional states. Examples include depression and bipolar disorder. Depression is characterized by prolonged feelings of sadness that impact daily life. Bipolar disorder involves extreme mood swings, ranging from highs (mania) to lows (depression).
-
Anxiety Disorders are characterized by an excessive and persistent sense of apprehension, with physical symptoms such as a rapid heartbeat or sweating, often without an identifiable trigger. Common types include generalized anxiety disorder, panic disorder, and social anxiety disorder.
-
Psychotic Disorders involve distorted thinking and awareness. Schizophrenia is a well-known psychotic disorder which affects how a person thinks, feels, and behaves, often resulting in a loss of touch with reality and might include delusions or hallucinations.
-
Eating Disorders are characterized by an unhealthy focus on food, body weight, and shape, leading to dangerous eating behaviors. Anorexia nervosa and bulimia nervosa are key examples. Anorexia nervosa involves a distorted body image that causes people to see themselves as overweight even when they are underweight, while bulimia nervosa involves episodes of overeating followed by purging.
Understanding the various categories of mental illness can aid in recognizing the diverse symptoms associated with each type.
Anxiety and Mood Disorders Overview
Anxiety and mood disorders affect millions worldwide, influencing how individuals feel, think, and handle daily activities. Anxiety disorders encompass a range of conditions where fear or worry does not go away and can worsen over time. These feelings can interfere with daily tasks such as job performance, school work, and relationships.
Mood disorders, also known as affective disorders, involve persistent feelings of sadness or periods of feeling overly happy, or fluctuations from extreme happiness to extreme sadness. The most common types are depression and bipolar disorder.
Understanding these conditions is vital for managing symptoms effectively. Both anxiety and mood disorders have treatments available that include:
- Medication
- Therapy
- A combination of both
Early intervention has been shown to improve outcomes.
Psychotic and Less Common Mental Illnesses
Psychotic disorders are a group of serious illnesses that affect the mind. These conditions impair an individual's ability to think clearly, make good judgments, respond emotionally, communicate effectively, understand reality, and behave appropriately. Symptoms of psychotic disorders can include hallucinations or delusions. Hallucinations involve seeing or hearing things that aren’t there, while delusions are characterized by false beliefs about what is happening or who one is.
Among these disorders, schizophrenia is perhaps the most known. It often involves a range of problems with thinking (cognition), behavior, or emotions. While psychosis can be a component of schizophrenia, the disorder also includes periods where symptoms might be less obvious.
Less common mental illnesses include conditions such as dissociative identity disorder (previously known as multiple personality disorder) and selective mutism.
- Dissociative identity disorder is marked by the experience of two or more distinct identities taking control of an individual's behavior at different times.
- Selective mutism is identified as a complex childhood anxiety disorder where a child is unable to speak in certain social situations, despite being able to speak comfortably in others.
Understanding these conditions contributes to a broader appreciation of the complexity of mental health issues, extending beyond the more frequently discussed depression and anxiety disorders. Awareness and education are vital for the early intervention and support for individuals affected by these diagnoses.

Eating Disorder Classifications
Eating disorders are complex mental health conditions characterized by abnormal eating behaviors and related thoughts and emotions. They are classified into various types, each with distinct features.
Anorexia Nervosa
Anorexia nervosa is marked by restricted food intake, an intense fear of gaining weight, and a distorted body image, leading individuals to perceive themselves as overweight even when they are underweight. This disorder results in a significantly low body weight for a person's age and height.
Bulimia Nervosa
Bulimia nervosa consists of episodes of binge eating followed by purging to prevent weight gain. Purging methods can include:
- Vomiting
- Excessive exercise
- The use of laxatives or diuretics
Individuals with bulimia often experience a loss of control during binge episodes.
Binge Eating disorder (BED)
Binge eating disorder is characterized by recurrent episodes of consuming large amounts of food in short periods, similar to bulimia nervosa, but without the compensatory purging behaviors. Episodes are accompanied by feelings of loss of control, guilt, or shame.
Avoidant/Restrictive Food Intake Disorder (ARFID)
ARFID involves the avoidance or restriction of food intake, not due to concerns about body weight or image, but because of:
- A lack of interest in eating
- Aversion to food colors, textures, or tastes
- Fear of aversive consequences like choking or vomiting
Each classification is defined by specific criteria based on psychological assessments and medical evaluations.
Impulse Control, Addiction, and Personality Disorders
Impulse Control Disorders (ICDs) are characterized by an inability to resist urges or impulses that may result in harm to oneself or others. These disorders are marked by a recognition of the harmful nature of these actions, coupled with a feeling of powerlessness to resist them. Addiction shares similarities with ICDs, with a focus on substance use or engagement in certain behaviors like gambling. Personality disorders encompass a broader range of issues, affecting individuals' thinking, feeling, and interactions, and can impact their ability to manage impulses and addiction.
The intersection of these conditions is important for understanding how to manage them. For example, Borderline personality disorder (BPD) is frequently associated with impulsivity and risky behaviors, including substance abuse. Similarly, Antisocial Personality Disorder is characterized by a disregard for norms and impulsive behavior.
Treatment options vary, often including therapy and, in some cases, medication. Cognitive Behavioral Therapy (CBT) has been shown to be effective in managing symptoms across these conditions, focusing on teaching coping mechanisms for impulsivity and addictive behaviors.
The role of patients in managing these conditions involves staying informed about their condition and the treatment options available, including clinical trials that offer innovative approaches not yet widely accessible.
Understanding OCD and PTSD
Obsessive-Compulsive Disorder (OCD) and Post-Traumatic Stress Disorder (PTSD) are mental health conditions that have a significant impact on many individuals worldwide. While these disorders can deeply affect a person's life, understanding their differences and similarities is key to recognizing their distinct characteristics.
OCD is identified by unwanted, intrusive thoughts (obsessions) and repetitive behaviors or mental acts (compulsions) that are performed in an effort to reduce anxiety triggered by these thoughts. An example of this is an individual with OCD who may have an excessive fear of germs, leading to compulsive hand-washing.
PTSD, in contrast, develops after experiencing or witnessing a traumatic event. Its symptoms include:
- Flashbacks of the trauma
- Avoidance of reminders of the event
- Increased reactivity (e.g., being easily startled)
- Negative changes in thoughts and mood associated with the traumatic experience.
Although both conditions are rooted in anxiety, they differ in their causes and expressions. Treatment frequently involves therapy—Cognitive Behavioral Therapy (CBT) being a common approach for both conditions. Medication may also be considered depending on the individual's circumstances.
