Anxiety is different from fear in that fear is defined as the emotional response to a present threat, whereas anxiety is the anticipation of a future one. It is often accompanied by nervous behavior such as pacing back and forth, somatic complaints, and rumination.
Major depressive disorder (MDD), also known as clinical depression, is a mental disorder characterized by at least two weeks of pervasive low mood, low self-esteem, and loss of interest or pleasure in normally enjoyable activities. Introduced by a group of US clinicians in the mid-1970s, the term was adopted by the American Psychiatric Association for this symptom cluster under mood disorders in the 1980 version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III), and has become widely used since. The disorder causes the second-most years lived with disability, after lower back pain.
A mental disorder, also referred to as a mental illness, a mental health condition, or a psychiatric disability, 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.
Schizophrenia is a mental disorder characterized by reoccurring episodes of psychosis that are correlated with a general misperception of reality. Other common signs include hallucinations, delusions, disorganized thinking and behavior, and flat or inappropriate affect. Symptoms develop gradually and typically begin during young adulthood and are never resolved. There is no objective diagnostic test; diagnosis is based on observed behavior, a psychiatric history that includes the person's reported experiences, and reports of others familiar with the person. For a diagnosis of schizophrenia, the described symptoms need to have been present for at least six months or one month. Many people with schizophrenia have other mental disorders, especially substance use disorders, depressive disorders, anxiety disorders, and obsessive–compulsive disorder.
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by executive dysfunction occasioning symptoms of inattention, hyperactivity, impulsivity and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and otherwise age-inappropriate.
Post-traumatic stress disorder (PTSD) is a mental and behavioral disorder that develops from experiencing a traumatic event, such as sexual assault, warfare, traffic collisions, child abuse, domestic violence, or other threats on a person's life or well-being. Symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress to trauma-related cues, attempts to avoid trauma-related cues, alterations in the way a person thinks and feels, and an increase in the fight-or-flight response. These symptoms last for more than a month after the event. Young children are less likely to show distress, but instead may express their memories through play. A person with PTSD is at a higher risk of suicide and intentional self-harm.
Depression is a mental state of low mood and aversion to activity. It affects more than 280 million people of all ages. Depression affects a person's thoughts, behavior, feelings, and sense of well-being. Depressed people often experience loss of motivation or interest in, or reduced pleasure or joy from, experiences that would normally bring them pleasure or joy.
A plant-based diet is a diet consisting mostly or entirely of plant-based foods. Plant-based diets encompass a wide range of dietary patterns that contain low amounts of animal products and high amounts of fiber-rich plant products such as vegetables, fruits, whole grains, legumes, nuts and seeds. They do not need to be vegan or vegetarian, but are defined in terms of low frequency of animal food consumption.
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.
Orthomolecular psychiatry is the use of orthomolecular medicine for mental illness. Orthomolecular psychiatry has been rejected by evidence-based medicine and has been called quackery. The approach uses unorthodox forms of individualized testing and diagnosis to attempt to establish an etiology for each patient's specific symptoms, and claims to tailor the treatment accordingly, using a combination of nutrients, dietary changes and medications that are claimed to enhance quality of life and functionality as well as to reduce or eliminate symptoms and the use of xenobiotic drugs. Scientific studies have shown mixed results; although there are some promising results from nutritional psychiatry, some forms of orthomolecular psychiatry are ineffective.
Suicide prevention is a collection of efforts to reduce the risk of suicide. Suicide is often preventable, and the efforts to prevent it may occur at the individual, relationship, community, and society level. Suicide is a serious public health problem that can have long-lasting effects on individuals, families, and communities. Preventing suicide requires strategies at all levels of society. This includes prevention and protective strategies for individuals, families, and communities. Suicide can be prevented by learning the warning signs, promoting prevention and resilience, and committing to social change.
Abram Hoffer was a Canadian biochemist, physician, and psychiatrist known for his "adrenochrome hypothesis" of schizoaffective disorders. According to Hoffer, megavitamin therapy and other nutritional interventions are potentially effective treatments for cancer and schizophrenia. Hoffer was also involved in studies of LSD as an experimental therapy for alcoholism and the discovery that high-dose niacin can be used to treat high cholesterol and other dyslipidemias. Hoffer's ideas about megavitamin therapy to treat mental illness are not accepted by the medical community.

Nutrition psychology (NP) is the psychological study of the relationship between dietary intake and different aspects of psychological health. It is an applied field that uses an interdisciplinary approach to examine the influence of diet on mental health. Nutrition psychology seeks to understand the relationship between nutritional behavior and mental health/well-being NP is a sub-field of psychology and more specifically of health psychology. It may be applied to numerous different fields including: psychology, dietetics, nutrition, and marketing. NP is a fairly new field with a brief history that has already started to contribute information and knowledge to psychology. There are two main areas of controversy within nutrition psychology. The first area of controversy is that the topic can be viewed in two different ways. It can be viewed as nutrition affecting psychological functions, or psychological choices and behavior influencing nutrition and health. The second controversy is the defining of what is "healthy" or "normal" as related to nutrition.

The relationships between digital media use and mental health have been investigated by various researchers—predominantly psychologists, sociologists, anthropologists, and medical experts—especially since the mid-1990s, after the growth of the World Wide Web. A significant body of research has explored "overuse" phenomena, commonly known as "digital addictions", or "digital dependencies." These phenomena manifest differently in many societies and cultures. Some experts have investigated the benefits of moderate digital media use in various domains, including in mental health, and the treatment of mental health problems with novel technological solutions.
