Bipolar disorder, previously known as manic depression or manic depressive disorder, is a mental disorder characterized by periods of depression and periods of abnormally elevated mood that each last from days to weeks. If the elevated mood is severe or associated with psychosis, it is called mania; if it is less severe and does not significantly affect functioning, it is called hypomania. During mania, an individual behaves or feels abnormally energetic, happy, or irritable, and they often make impulsive decisions with little regard for the consequences; there is usually also a reduced need for sleep during manic phases. During periods of depression, the individual may experience crying, have a negative outlook on life, and demonstrate poor eye contact with others. The risk of suicide is high; over a period of 20 years, 6% of those with bipolar disorder died by suicide, while 30–40% engaged in self-harm. Other mental health issues, such as anxiety disorders and substance use disorders, are commonly associated with bipolar disorder. The global prevalence of bipolar disorder is estimated to be between 1-5% of the world's popluation.
Paranoia is an instinct or thought process that is believed to be heavily influenced by anxiety, suspicion, or fear, often to the point of delusion and irrationality. Paranoid thinking typically includes persecutory beliefs, or beliefs of conspiracy concerning a perceived threat towards oneself. Paranoia is distinct from phobias, which also involve irrational fear, but usually no blame.
Avolition or amotivation as a symptom of various forms of psychopathology, is the decrease in the ability to initiate and persist in self-directed purposeful activities. Such activities that appear to be neglected usually include routine activities, including hobbies, going to work or school, and most notably, engaging in social activities.

Paranoid personality disorder (PPD) is a mental disorder characterized by paranoia, and a pervasive, long-standing suspiciousness and generalized mistrust of others. People with this personality disorder may be hypersensitive, easily insulted, and habitually relate to the world by vigilant scanning of the environment for clues or suggestions that may validate their fears or biases. They are eager observers and they often think they are in danger and look for signs and threats of that danger, potentially not appreciating other interpretations or evidence.
The Hearing Voices Movement (HVM) is the name used by organizations and individuals advocating the "hearing voices approach", an alternative way of understanding the experience of those people who "hear voices". In the medical professional literature, ‘voices’ are most often referred to as auditory verbal hallucinations.

Prairie madness or prairie fever was an affliction that affected European settlers in the Great Plains during their migration to, and settlement of, the Canadian Prairies and the Western United States in the 19th century. Settlers moving from urbanized or relatively settled areas in the East faced the risk of mental breakdown caused by the harsh living conditions and the extreme levels of isolation on the prairie. Symptoms of prairie madness included depression, withdrawal, changes in character and habit, and violence. Prairie madness sometimes resulted in the afflicted person moving back East or, in extreme cases, suicide.

Incident stress is a condition caused by acute stress which overwhelms a staff person trained to deal with critical incidents such as within the line of duty for first responders, EMTs, and other similar personnel. If not recognized and treated at onset, incident stress can lead to more serious effects of posttraumatic stress disorder.
The Rivermead Post-Concussion Symptoms Questionnaire, abbreviated RPQ, is a questionnaire that can be administered to someone who sustains a concussion or other form of traumatic brain injury to measure the severity of symptoms. The RPQ is used to determine the presence and severity of post-concussion syndrome (PCS), a set of somatic, cognitive, and emotional symptoms following traumatic brain injury that may persist anywhere from a week, to months, or even more than six months.
Sundowning, or sundown syndrome, is a neurological phenomenon associated with increased confusion and restlessness in people with delirium or some form of dementia. It is most commonly associated with Alzheimer's disease but is also found in those with other forms of dementia. The term sundowning was coined by nurse Lois K. Evans in 1987 due to the timing of the person's increased confusion beginning in the late afternoon and early evening. For people with sundown syndrome, a multitude of behavioral problems begin to occur and are associated with long-term adverse outcomes. Sundowning seems to occur more frequently during the middle stages of Alzheimer's disease and mixed dementia and seems to subside with the progression of the person's dementia. People are generally able to understand that this behavioral pattern is abnormal. Research shows that 20–45% of people with Alzheimer's will experience some variation of sundowning confusion. However, despite lack of an official diagnosis of sundown syndrome in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), there is currently a wide range of reported prevalence.

The delusion can be found in various disorders, being more usual in psychotic disorders.
The COVID-19 pandemic has impacted the mental health of people across the globe. The pandemic has caused widespread anxiety, depression, and post-traumatic stress disorder symptoms. According to the UN health agency WHO, in the first year of the COVID-19 pandemic, prevalence of common mental health conditions, such as depression and anxiety, went up by more than 25 percent. The pandemic has damaged social relationships, trust in institutions and in other people, has caused changes in work and income, and has imposed a substantial burden of anxiety and worry on the population. Women and young people face the greatest risk of depression and anxiety. According to The Centers for Disease Control and Prevention study of Mental Health, Substance Use, and Suicidal Ideation During the COVID-19 Pandemic, "63 percent of young people reported experiencing substantial symptoms of anxiety and depression".
