A mental disorder, also referred to as a mental illness, a mental health condition, or a psychiatric disorder, is a behavioral or mental pattern that causes significant distress or impairment of personal functioning. A mental disorder is also characterized by a clinically significant disturbance in an individual's cognition, emotional regulation, or behavior, often in a social context. Such disturbances may occur as single episodes, may be persistent, or may be relapsing–remitting. There are many different types of mental disorders, with signs and symptoms that vary widely between specific disorders. A mental disorder is one aspect of mental health.
Health has a variety of definitions, which have been used for different purposes over time. Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress. Some factors affecting health are due to individual choices, such as whether to engage in a high-risk behavior, while others are due to structural causes, such as whether the society is arranged in a way that makes it easier or harder for people to get necessary healthcare services. Still, other factors are beyond both individual and group choices, such as genetic disorders.
Elder abuse is "a single, or repeated act, or lack of appropriate action, occurring within any relationship where there is an expectation of trust, which causes harm or distress to an older person." This definition has been adopted by the World Health Organization (WHO) from a definition put forward by Hourglass in the UK. Laws protecting the elderly from abuse are similar to and related to laws protecting dependent adults from abuse.
A factitious disorder is a mental disorder in which a person, without a malingering motive, acts as if they have an illness by deliberately producing, feigning, or exaggerating symptoms, purely to attain a patient's role. People with a factitious disorder may produce symptoms by contaminating urine samples, taking hallucinogens, injecting fecal material to produce abscesses, and similar behaviour. The word factitious derives from the Latin word factītius, meaning "human-made".
Mental health encompasses emotional, psychological, and social well-being, influencing cognition, perception, and behavior. According to World Health Organization (WHO), it is a "state of well-being in which the individual realizes his or her abilities, can cope with the normal stresses of life, can work productively and fruitfully, and can contribute to his or her community". It likewise determines how an individual handles stress, interpersonal relationships, and decision-making. Mental health includes subjective well-being, perceived self-efficacy, autonomy, competence, intergenerational dependence, and self-actualization of one's intellectual and emotional potential, among others. From the perspectives of positive psychology or holism, mental health may include an individual's ability to enjoy life and to create a balance between life activities and efforts to achieve psychological resilience. Cultural differences, personal philosophy, subjective assessments, and competing professional theories all affect how one defines "mental health". Some early signs related to mental health difficulties are sleep irritation, lack of energy, lack of appetite, thinking of harming oneself or others, self-isolating, and frequently zoning out.
Developmental disability is a diverse group of chronic conditions, comprising mental or physical impairments that arise before adulthood. Developmental disabilities cause individuals living with them many difficulties in certain areas of life, especially in "language, mobility, learning, self-help, and independent living". Developmental disabilities can be detected early on and persist throughout an individual's lifespan. Developmental disability that affects all areas of a child's development is sometimes referred to as global developmental delay.
Psychiatric nursing or mental health nursing is the appointed position of a nurse that specialises in mental health, and cares for people of all ages experiencing mental illnesses or distress. These include: neurodevelopmental disorders, schizophrenia, schizoaffective disorder, mood disorders, addiction, anxiety disorders, personality disorders, eating disorders, suicidal thoughts, psychosis, paranoia, and self-harm.
Self-care has been defined as the process of establishing behaviors to ensure holistic well-being of oneself, to promote health, and actively manage illness when it occurs. Individuals engage in some form of self-care daily with food choices, exercise, sleep, and hygiene. Self-care is not only a solo activity, as the community—a group that supports the person performing self-care—overall plays a role in access to, implementation of, and success of self-care activities.
Hospitalism was a pediatric diagnosis used in the 1930s to describe infants who wasted away while in a hospital. The symptoms could include decreased physical development and disruption of perceptual-motor skills and language. In the first half of the 20th century, hospitalism was discovered to be linked to social deprivation between an infant and its caregiver. The term was in use in 1945, but the term can be traced back as early as 1897.
A mental health professional is a health care practitioner or social and human services provider who offers services for the purpose of improving an individual's mental health or to treat mental disorders. This broad category was developed as a name for community personnel who worked in the new community mental health agencies begun in the 1970s to assist individuals moving from state hospitals, to prevent admissions, and to provide support in homes, jobs, education, and community. These individuals were the forefront brigade to develop the community programs, which today may be referred to by names such as supported housing, psychiatric rehabilitation, supported or transitional employment, sheltered workshops, supported education, daily living skills, affirmative industries, dual diagnosis treatment, individual and family psychoeducation, adult day care, foster care, family services and mental health counseling.
The recovery model, recovery approach or psychological recovery is an approach to mental disorder or substance dependence that emphasizes and supports a person's potential for recovery. Recovery is generally seen in this model as a personal journey rather than a set outcome, and one that may involve developing hope, a secure base and sense of self, supportive relationships, empowerment, social inclusion, coping skills, and meaning. Recovery sees symptoms as a continuum of the norm rather than an aberration and rejects sane-insane dichotomy.
A caregiver, carer or support worker is a paid or unpaid person who helps an individual with activities of daily living. Caregivers who are members of a care recipient's family or social network, and who may have no specific professional training, are often described as informal caregivers. Caregivers most commonly assist with impairments related to old age, disability, a disease, or a mental disorder.
Psychoeducation is an evidence-based therapeutic intervention for patients and their loved ones that provides information and support to better understand and cope with illness. Psychoeducation is most often associated with serious mental illness, including dementia, schizophrenia, clinical depression, anxiety disorders, eating disorders, bipolar and personality disorders. The term has also been used for programs that address physical illnesses, such as cancer.
A psychiatric assessment, or psychological screening, is the process of gathering information about a person within a psychiatric service, with the purpose of making a diagnosis. The assessment is usually the first stage of a treatment process, but psychiatric assessments may also be used for various legal purposes. The assessment includes social and biographical information, direct observations, and data from specific psychological tests. It is typically carried out by a psychiatrist, but it can be a multi-disciplinary process involving nurses, psychologists, occupational therapist, social workers, and licensed professional counselors.
Services for mental health disorders provide treatment, support, or advocacy to people who have psychiatric illnesses. These may include medical, behavioral, social, and legal services.
In a study in Western societies, homeless people have a higher prevalence of mental illness when compared to the general population. They also are more likely to suffer from alcoholism and drug dependency. It is estimated that 20–25% of homeless people, compared with 6% of the non-homeless, have severe mental illness. Others estimate that up to one-third of the homeless have a mental illness. In January 2015, the most extensive survey ever undertaken found 564,708 people were homeless on a given night in the United States. Depending on the age group in question and how homelessness is defined, the consensus estimate as of 2014 was that, at minimum, 25% of the American homeless—140,000 individuals—were seriously mentally ill at any given point in time. 45% percent of the homeless—250,000 individuals—had any mental illness. More would be labeled homeless if these were annual counts rather than point-in-time counts. Being chronically homeless also means that people with mental illnesses are more likely to experience catastrophic health crises requiring medical intervention or resulting in institutionalization within the criminal justice system. Majority of the homeless population do not have a mental illness. Although there is no correlation between homelessness and mental health, those who are dealing with homelessness are struggling with psychological and emotional distress. The Substance Abuse and Mental Health Services Administration conducted a study and found that in 2010, 26.2 percent of sheltered homeless people had a severe mental illness.
Post-intensive care syndrome (PICS) describes a collection of health disorders that are common among patients who survive critical illness and intensive care. Generally, PICS is considered distinct from the impairments experienced by those who survive critical illness and intensive care following traumatic brain injury and stroke. The range of symptoms that PICS describes falls under three broad categories: physical impairment, cognitive impairment, and psychiatric impairment. A person with PICS may have symptoms from one or multiple of these categories.
Involuntary commitment or civil commitment is a legal process through which an individual who is deemed by a qualified agent to have symptoms of severe mental disorder is detained in a psychiatric hospital (inpatient) where they can be treated involuntarily.
Geriatric psychology is a subfield of psychology that specializes in the mental and physical health of individuals in the later stages of life. These specialized psychologists study a variety of psychological abilities that deplete as aging occurs such as memory, learning capabilities, and coordination. Geriatric psychologists work with elderly clients to conduct the diagnosis, study, and treatment of certain mental illnesses in a variety of workplace settings. Common areas of practice include loneliness in old age, depression, dementia, Alzheimer's disease, vascular dementia, and Parkinson's disease.
Mental health inequality refers to the differences in the quality, access, and health care different communities and populations receive for mental health services. Globally, the World Health Organization estimates that 350 million people are affected with depressive disorders. Mental health can be defined as an individual's well-being and/or the absence of clinically defined mental illness. Inequalities that can occur in mental healthcare may include mental health status, access to and quality of care, and mental health outcomes, which may differ across populations of different race, ethnicity, sexual orientation, sex, gender, socioeconomic statuses, education level, and geographic location. Social determinants of health, more specifically the social determinants of mental health, that can influence an individual's susceptibility to developing mental disorders and illnesses include, but are not limited to, economic status, education level, demographics, geographic location and genetics.
