What is Mental Illness?
Mental illness refers to a wide range of conditions that affect mood, thinking, and behavior. It can be mild or severe and requires long-term professional treatment. Early detection and proper care optimize recovery.
Signs and Symptoms of Mental Illness
There are several general signs and symptoms that could indicate someone is experiencing a mental illness:
- Changes in mood: Feeling unusually sad, anxious, empty, hopeless, worried, or irritable throughout most of the day, nearly every day.
- Changes in personality: Significant changes in personality that are not typical for the individual, such as new risky behavior, hostility, or increased anger.
- Changes in behavior: Behaviors such as social isolation, avoiding activities that were once enjoyed, increased aggression or withdrawal from family and friends can indicate a mental illness.
- Changes in perception: Experiencing hallucinations, episodes of mania, or delusional thoughts could be signs of serious mental illnesses like schizophrenia or bipolar disorder.
- Changes in concentration and memory: Trouble focusing, making decisions, or remembering things could signal conditions like depression or anxiety.
- Changes in sleep and appetite: Sleeping too much or too little, sudden weight loss or gain, could indicate an underlying mental health issue.
- Loss of interest in self-care: Neglecting hygiene, diet, exercise, or medical/dental care beyond what is typical for the individual points to possible mental illness.
- Increased substance use: Using alcohol or drugs in excess as a way to cope with mental or emotional problems needs medical evaluation.
- Physical ailments: Unexplained chronic pain, headaches, and digestive issues that don’t resolve could be related to psychiatric conditions.
- Self-harm or suicidal thoughts: Thinking about or attempting suicide is always a medical emergency requiring immediate help.
Types of Mental Illnesses
There are several major categories of mental illnesses. Recognizing the signs is important, but most people are not able to diagnose themselves. Consulting a licensed mental health professional is advised if the symptoms persist for weeks or longer. Here is an overview of some common mental illness types:
- Anxiety Disorders
- Mood Disorders
- Psychotic Disorders
- Eating Disorders
- Substance Use Disorders
- Personality Disorders
- Neurodevelopmental Disorders
- Obsessive Compulsive Disorder (OCD)
This was a broad overview of common mental illness symptoms and types. The next section will delve deeper into some of the more prevalent conditions.
Anxiety Disorders
Anxiety disorders are among the most common forms of mental illness. It is estimated that nearly 1 in 5 Americans will experience an anxiety disorder in their lifetime. Some of the major types include:
- Generalized anxiety disorder causes chronic, exaggerated worry about everyday life activities and events. Physical symptoms like headaches, nausea, and fatigue can occur.
- Social anxiety disorder involves excessive fear of social situations and being evaluated by others. Avoiding gatherings or speaking in public due to anxiety are hallmarks.
- Panic disorder results in unexpected and recurring panic attacks where the individual experiences intense fear and physical symptoms lasting minutes. Worrying over future attacks is also common.
- Specific phobias relate to irrational fears of particular objects or situations that pose little real threat, like flying, heights, snakes, etc. Avoidance behaviors are persistent.
Mood Disorders
The three most prevalent mood disorders are major depressive disorder, persistent depressive disorder, and bipolar disorder:
- Major depressive disorder causes depressed mood, loss of interest in usually enjoyable activities, changes in appetite, sleep, energy levels, concentration difficulties, and sometimes suicidal thoughts. Episodes typically last at least two weeks.
- Persistent depressive disorder (previously dysthymia) involves chronic but less severe symptoms of depression for at least two years during periods where criteria for major depression have not been met.
- Bipolar disorder is characterized by extreme mood swings between mania and depression. Mania causes unusually elevated mood, racing thoughts, and risky behaviors, while depression brings severe sadness and potentially suicidal thoughts. Proper diagnosis and treatment are crucial to manage this condition.
Psychotic Disorders
Psychotic disorders involve loss of contact with reality through hallucinations or delusions. Schizophrenia and schizoaffective disorder are two of the most serious mental illnesses:
- Schizophrenia causes disrupted thinking, perceptions, emotion, language, and sense of self. Symptoms may include delusions, hallucinations, disorganized speech/behavior, and catatonia. Onset is often in the late teens to 30s.
- Schizoaffective disorder features psychotic symptoms as well as mood episodes meeting the criteria for depression or bipolar disorder. Diagnosis requires the presence of psychosis and mood symptoms for a period of time.
Eating Disorders
Eating disorders are another group of serious conditions:
- Anorexia nervosa involves a lack of weight maintenance due to refusal to eat adequately, intense fear of gaining weight, and distorted body image.
- Bulimia nervosa is characterized by binge eating episodes followed by purging behaviors like vomiting, laxative use, and fasting to compensate for overeating.
- Binge eating disorder involves frequent consumption of unusually large amounts of food coupled with feeling unable to stop or control eating episodes.
Neurodevelopmental Disorders
Neurodevelopmental disorders involve atypical brain development that impacts function:
- Autism spectrum disorder (ASD) affects social communication and restricted/repetitive behaviors. Symptoms must be present in early development but may not fully manifest until social demands increase.
- Attention deficit hyperactivity disorder (ADHD) involves a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning. Symptoms appear in childhood.
Obsessive Compulsive Disorder
Obsessive-compulsive disorder involves distressing, intrusive thoughts (obsessions) and repetitive behaviors or mental acts (compulsions) performed to temporarily reduce associated anxiety:
- Common obsessions include contamination fears, unwanted terrible thoughts, and the need for symmetry/order.
- Compulsions can include excessive handwashing, counting, arranging, and checking.
