Mental Health Diagnosis Terms 

Addiction

Addiction is a complex condition, a brain disease that is manifested by compulsive substance use despite harmful consequence. People with addiction (severe substance use disorder) have an intense focus on using a certain substance(s), such as alcohol or drugs, to the point that it takes over their life. They keep using alcohol or a drug even when they know it will cause problems. Yet a number of effective treatments are available and people can recover from addiction and lead normal, productive lives.

Anorexia

Anorexia has the highest mortality rate of any psychiatric illness. It is an eating disorder characterized by restricting food, intense fears of weight gain, and distorted body image. Inadequate calorie intake and/or excessive energy expenditure result in potentially life-threatening damage to the body and metabolism. Supportive care by health care providers, structured behavioral therapy, psychotherapy, and anti-depressant drug therapy are some of the methods that are used for treatment. Despite stereotypes perpetuated by media, anyone, regardless of gender, race, or sexuality, can develop Anorexia.

Agoraphobia

A fear and avoidance of situations where you might feel unsafe or unable to escape if you have a panic attack

Anti-Social Personality Disorder

Persons with this disorder characteristically disregard the feelings, property, authority, and respect of others, for their own personal gain. This may include violent or aggressive acts involving or targeting other individuals, without a sense or remorse or guilt for any of their destructive actions

Anxiety

Anxiety is your body’s natural response to stress. It is a feeling of fear and apprehension about what’s to come. Symptoms range from chronic, exaggerated worry, tension, and irritability and appear to have no cause or are more intense than the situation warrants. Physical signs, such as restlessness, trouble falling or staying asleep, headaches, trembling, twitching, muscle tension, or sweating, often accompany these psychological symptoms. Anxiety is among the most common, most treatable mental disorders.

Anxiety Disorders

Anxiety disorders range from feelings of uneasiness to immobilizing bouts of terror. Most people experience anxiety at some point in their lives and some nervousness in anticipation of a real situation. However if a person cannot shake unwarranted worries, or if the feelings are jarring to the point of avoiding everyday activities, he or she most likely has an anxiety disorder.

Attention Deficit Hyperactivity Disorder(ADD-ADHD)

Attention-deficit/hyperactivity disorder, sometimes called ADHD, is a chronic condition and the most commonly diagnosed behavioral disorder among children and adolescents. It affects between 3 and 5 percent of school-aged children in a 6-month period (U.S. Department of Health and Human Services, 1999). Children and adolescents with attention-deficit/hyperactivity disorder have difficulty controlling their behavior in school and social settings. They also tend to be accident-prone. Although some of these young people may not earn high grades in school, most have normal or above-normal intelligence.

Asperger’s

Is often considered to be a developmental disorder that can usually be diagnosed prior to adolescence. People with Asperger’s experience repetitive and restrictive behaviours and interests that may lead to impaired functioning at work and socially. Asperger’s is considered one of the several disorders on the Autism Spectrum and is unique because there is no significant delay in language development. Many people with Asperger’s live full and productive lives without any (or minimal) treatment. Recent research is challenging the idea that Asperger’s is a disorder but much more study of this is needed.

Autism

Autism, also called autistic disorder, is a complex developmental disability that appears in early childhood, usually before age 3. Autism prevents children and adolescents from interacting normally with other people and affects almost every aspect of their social and psychological development.

Avoidant Personality Disorder

Persons with this disorder are hypersensitive to rejection and thus, avoid situations with any potential for conflict. This reaction is fear-driven, however, persons with avoidant personality disorder become disturbed by their own social isolation, withdrawal, and inability to form close, interpersonal relationships.

Binge Eating Disorder

Binge eating disorder (BED) is a severe, life-threatening, and treatable eating disorder characterized by recurrent episodes of eating large quantities of food (often very quickly and to the point of discomfort); a feeling of a loss of control during the binge; experiencing shame, distress or guilt afterwards; and not regularly using unhealthy compensatory measures (e.g., purging) to counter the binge eating. It is the most common eating disorder in the United States.

Bipolar Disorder

Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks.

There are four basic types of bipolar disorder; all of them involve clear changes in mood, energy, and activity levels. These moods range from periods of extremely “up,” elated, and energized behaviour (known as manic episodes) to very sad, “down,” or hopeless periods (known as depressive episodes). Less severe manic periods are known as hypomanic episodes.

Borderline Personality Disorder

Symptoms of borderline personality disorder, a serious mental illness, include pervasive instability in moods, interpersonal relationships, self-image, and behaviour. The instability can affect family and work life, long-term planning, and the individual's sense of self-identity.

Bulimia Nervosa

Bulimia nervosa is an eating disorder characterized by excessive eating. People who have bulimia will eat an excessive amount of food in a single episode and almost immediately make themselves vomit or use laxatives or diuretics (water pills) to get rid of the food in their bodies. This behaviour often is referred to as the "binge/purge" cycle. Like people with anorexia, people with bulimia have an intense fear of gaining weight.

Compulsion

Individuals engaging in compulsions typically feel an irresistible need to engage in the compulsive behaviour. Everyday behaviours such as hand-washing, praying, and counting can become compulsions.

It causes severe symptoms that affect how you feel, think, and handle daily activities, such as sleeping, eating, or working. To be diagnosed with depression, the symptoms must be present for at least two weeks.

Dyslexia

Dyslexia is a language-based learning disability. Dyslexia refers to a cluster of symptoms, which result in people having difficulties with specific language skills, particularly reading. Students with dyslexia usually experience difficulties with other language skills such as spelling, writing, and pronouncing words. Dyslexia affects individuals throughout their lives; however, its impact can change at different stages in a person’s life. It is referred to as a learning disability because dyslexia can make it very difficult for a student to succeed academically in the typical instructional environment, and in its more severe forms, will qualify a student for special education, special accommodations, or extra support services.

Some people may develop mental health concerns as a result of distress experienced with gender dysphoria, but this incongruence itself is not a mental health condition, just as being transgender is not a mental health condition.

Many—though not all—trans people experience dysphoria. Non-binary, agender, and other gender non-conforming individuals might also experience dysphoria, as may some intersex people. Anxiety, depression, stress, and feelings of isolation may develop in those who experience dysphoria, and a therapist or counsellor can offer support to individuals coping with these and other concerns.

When stressed, the body thinks it is under attack and switches to ‘fight or flight’ mode, releasing a complex mix of hormones and chemicals such as adrenaline, cortisol and norepinephrine to prepare the body for physical action.
