Specific phobia is an anxiety disorder, characterized by an extreme, unreasonable, and irrational fear associated with a specific object, situation, or concept which poses little or no actual danger. Specific phobia can lead to avoidance of the object or situation, persistence of the fear, and significant distress or problems functioning associated with the fear. A phobia can be the fear of anything.
Hypochondriasis or hypochondria is a condition in which a person is excessively and unduly worried about having a serious illness. Hypochondria is an old concept whose meaning has repeatedly changed over its lifespan. It has been claimed that this debilitating condition results from an inaccurate perception of the condition of body or mind despite the absence of an actual medical diagnosis. An individual with hypochondriasis is known as a hypochondriac. Hypochondriacs become unduly alarmed about any physical or psychological symptoms they detect, no matter how minor the symptom may be, and are convinced that they have, or are about to be diagnosed with, a serious illness.
Dependent personality disorder (DPD) is characterized by a pervasive psychological dependence on other people. This personality disorder is a long-term condition in which people depend on others to meet their emotional and physical needs, with only a minority achieving normal levels of independence. Dependent personality disorder is a cluster C personality disorder, which is characterized by excessive fear and anxiety. It begins prior to early adulthood, and it is present in a variety of contexts and is associated with inadequate functioning. Symptoms can include anything from extreme passivity, devastation or helplessness when relationships end, avoidance of responsibilities, and severe submission.
Avoidant personality disorder (AvPD) or Anxious personality disorder is a Cluster C personality disorder characterized by excessive social anxiety and inhibition, fear of intimacy, severe feelings of inadequacy and inferiority, and an overreliance on avoidance of feared stimuli as a maladaptive coping method. Those affected typically display a pattern of extreme sensitivity to negative evaluation and rejection, a belief that one is socially inept or personally unappealing to others, and avoidance of social interaction despite a strong desire for it. It appears to affect an approximately equal number of men and women.
Reactive attachment disorder (RAD) is described in clinical literature as a severe and relatively uncommon disorder that can affect children, although these issues do occasionally persist into adulthood. RAD is characterized by markedly disturbed and developmentally inappropriate ways of relating socially in most contexts. It can take the form of a persistent failure to initiate or respond to most social interactions in a developmentally appropriate way—known as the "inhibited form". In the DSM-5, the "disinhibited form" is considered a separate diagnosis named "disinhibited attachment disorder".
Child psychopathology refers to the scientific study of mental disorders in children and adolescents. Oppositional defiant disorder, attention-deficit hyperactivity disorder, and autism spectrum disorder are examples of psychopathology that are typically first diagnosed during childhood. Mental health providers who work with children and adolescents are informed by research in developmental psychology, clinical child psychology, and family systems. Lists of child and adult mental disorders can be found in the International Statistical Classification of Diseases and Related Health Problems, 10th Edition (ICD-10), published by the World Health Organization (WHO) and in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), published by the American Psychiatric Association (APA). In addition, the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood is used in assessing mental health and developmental disorders in children up to age five.
Dissociative disorders (DD) are conditions that involve disruptions or breakdowns of memory, awareness, identity, or perception. People with dissociative disorders use dissociation as a defense mechanism, pathologically and involuntarily. The individual experiences these dissociations to protect themselves. Some dissociative disorders are triggered by psychological trauma, but depersonalization-derealization disorder may be preceded only by stress, psychoactive substances, or no identifiable trigger at all.
Complex post-traumatic stress disorder (CPTSD) is a stress-related mental disorder generally occurring in response to complex traumas, i.e. commonly prolonged or repetitive exposures to a series of traumatic events, within which individuals perceive little or no chance to escape.
Childhood trauma is often described as serious adverse childhood experiences (ACEs). Children may go through a range of experiences that classify as psychological trauma; these might include neglect, abandonment, sexual abuse, emotional abuse, and physical abuse, witnessing abuse of a sibling or parent, or having a mentally ill parent. These events have profound psychological, physiological, and sociological impacts and can have negative, lasting effects on health and well-being such as unsocial behaviors, attention deficit hyperactivity disorder (ADHD), and sleep disturbances. Similarly, children whose mothers have experienced traumatic or stressful events during pregnancy have an increased risk of mental health disorders and other neurodevelopmental disorders.
Traumatic stress is a common term for reactive anxiety and depression, although it is not a medical term and is not included in the Diagnostic and Statistical Manual of Mental Disorders (DSM). The experience of traumatic stress include subtypes of anxiety, depression and disturbance of conduct along with combinations of these symptoms. This may result from events that are less threatening and distressing than those that lead to post-traumatic stress disorder. The fifth edition of the DSM describes in a section titled "Trauma and Stress-Related Disorders" disinhibited social engagement disorder, reactive attachment disorder, acute stress disorder, adjustment disorder, and post-traumatic stress disorder.
Mental disorders diagnosed in childhood can be neurodevelopmental, emotional, or behavioral disorders. These disorders negatively impact the mental and social wellbeing of a child, and children with these disorders require support from their families and schools. Childhood mental disorders often persist into adulthood. These disorders are usually first diagnosed in infancy, childhood, or adolescence, as laid out in the DSM-5 and in the ICD-11.
Victimization refers to a person being made into a victim by someone else and can take on psychological as well as physical forms, both of which are damaging to victims. Forms of victimization include bullying or peer victimization, physical abuse, sexual abuse, verbal abuse, robbery, and assault. Some of these forms of victimization are commonly associated with certain populations, but they can happen to others as well. For example, bullying or peer victimization is most commonly studied in children and adolescents but also takes place between adults. Although anyone may be victimized, particular groups may be more susceptible to certain types of victimization and as a result to the symptoms and consequences that follow. Individuals respond to victimization in a wide variety of ways, so noticeable symptoms of victimization will vary from person to person. These symptoms may take on several different forms, be associated with specific forms of victimization, and be moderated by individual characteristics of the victim and/or experiences after victimization.
Childhood schizophrenia is similar in characteristics of schizophrenia that develops at a later age, but has an onset before the age of 13 years, and is more difficult to diagnose. Schizophrenia is characterized by positive symptoms that can include hallucinations, delusions, and disorganized speech; negative symptoms, such as blunted affect and avolition and apathy, and a number of cognitive impairments. Differential diagnosis is problematic since several other neurodevelopmental disorders, including autism spectrum disorder, language disorder, and attention deficit hyperactivity disorder, also have signs and symptoms similar to childhood-onset schizophrenia.
Autophobia, also called monophobia, isolophobia, or eremophobia, is the specific phobia or a morbid fear or dread of oneself or of being alone, isolated, abandoned, and ignored. This specific phobia is associated with the idea of being alone, causing severe anxiety
A childhood phobia is an exaggerated, intense fear "that is out of proportion to any real fear" found in children. It is often characterized by a preoccupation with a particular object, class of objects, or situation that one fears. A phobic reaction is twofold—the first part being the "intense irrational fear" and the second part being "avoidance."
The Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood-Revised is a developmentally based diagnostic manual that provides clinical criteria for categorizing mental health and developmental disorders in infants and toddlers. It is organized into a five-part axis system. The book has been translated into several languages, and its model is utilized for the assessment of children up to five years of age.
Separation anxiety disorder (SAD) is an anxiety disorder in which an individual experiences excessive anxiety regarding separation from home and/or from people to whom the individual has a strong emotional attachment. Separation anxiety is a natural part of the developmental process. It is most common in infants and little children, typically between the ages of six to seven months to three years, although it may pathologically manifest itself in older children, adolescents and adults. Unlike SAD, normal separation anxiety indicates healthy advancements in a child's cognitive maturation and should not be considered a developing behavioral problem.
Emotional abandonment is a subjective emotional state in which people feel undesired, left behind, insecure, or discarded. People experiencing emotional abandonment may feel at a loss. They may feel like they have been cut off from a crucial source of sustenance or feel withdrawn, either suddenly or through a process of erosion. Emotional abandonment can manifest through loss or separation from a loved one.
Externalizing disorders are mental disorders characterized by externalizing behaviors, maladaptive behaviors directed toward an individual's environment, which cause impairment or interference in life functioning. In contrast to individuals with internalizing disorders who internalize their maladaptive emotions and cognitions, such feelings and thoughts are externalized in behavior in individuals with externalizing disorders. Externalizing disorders are often specifically referred to as disruptive behavior disorders or conduct problems which occur in childhood. Externalizing disorders, however, are also manifested in adulthood. For example, alcohol- and substance-related disorders and antisocial personality disorder are adult externalizing disorders. Externalizing psychopathology is associated with antisocial behavior, which is different from and often confused for asociality.
Early childhood trauma refers to various types of adversity and traumatic events experienced during the early years of a person's life. This is deemed the most critical developmental period in human life by psychologists. A critical period refers to a sensitive time during the early years of childhood in which children may be more vulnerable to be affected by environmental stimulation. These traumatic events can include serious sickness, natural disasters, family violence, sudden separation from a family member, being the victim of abuse, or suffering the loss of a loved one. Traumatic experiences in early childhood can result in severe consequences throughout adulthood, for instance developing post-traumatic stress disorder, depression, or anxiety. Negative childhood experiences can have a tremendous impact on future violence victimization and perpetration, and lifelong health and opportunity. However, not all children who are exposed to negative stimuli in early childhood will be affected severely in later life; some children come out unscathed after being faced with traumatic events, which is known as resilience. Many factors can account for the invulnerability displayed by certain children in response to adverse social conditions: gender, vulnerability, social support systems, and innate character traits. Much of the research in this area has referred to the Adverse Childhood Experiences Study (ACE) study. The ACE study found several protective factors against developing mental health disorders, including mother-child relations, parental health, and community support. However, having adverse childhood experiences creates long-lasting impacts on psychosocial functioning, such as a heightened awareness of environmental threats, feelings of loneliness, and cognitive deficits. Individuals with ACEs are more prone to developing severe symptoms than individuals in the same diagnostic category.
