Mental illness, also known as a mental health disorder, refers to a wide range of conditions that affect a person’s mood, thinking, behavior, and overall functioning. These conditions can cause significant distress and impair daily life activities, such as work, school, and relationships. It’s important to understand that mental illness is a health condition, just like physical illnesses, and is not a result of personal weakness or a character flaw.
Key Aspects of Mental Illness:
- Disturbance in Functioning: Mental illnesses involve significant changes in cognitive processes (thinking, memory, perception), emotional regulation (mood, feelings), or behavior that deviate from cultural norms and cause distress or impairment.
- Spectrum of Severity: Mental illnesses range from mild to severe, and their impact on an individual’s life can vary greatly.
- Not Always Visible: Unlike physical illnesses, the signs of mental illness are not always obvious, which can lead to misunderstanding and stigma.
- Treatable: With appropriate treatment and support, many individuals with mental illness can experience significant improvement and lead fulfilling lives.
Different Types of Mental Illness:
There are numerous recognized mental illnesses, categorized based on their primary symptoms. Some of the main categories include:
- Anxiety Disorders: Characterized by excessive fear, worry, and related behavioral disturbances. Examples include:
- Generalized Anxiety Disorder (GAD)
- Panic Disorder
- Social Anxiety Disorder
- Specific Phobias
- Obsessive-Compulsive Disorder (OCD)
- Post-Traumatic Stress Disorder (PTSD)
- Mood Disorders: Involve significant disturbances in mood, affecting energy levels, activity, judgment, behavior, and the ability to function in everyday life. Examples include:
- Major Depressive Disorder (MDD)
- Bipolar Disorder
- Persistent Depressive Disorder (Dysthymia)
- Psychotic Disorders: Characterized by a detachment from reality, often involving hallucinations (seeing or hearing things that aren’t there) and delusions (false beliefs). The most well-known example is:

Examples include:
- Borderline Personality Disorder
- Narcissistic Personality Disorder
- Antisocial Personality Disorder
- Trauma- and Stressor-Related Disorders: Develop following exposure to a traumatic or stressful event. PTSD is a primary example.
