Mania ( ; also known as manic syndrome) is a psychiatric behavioral syndrome defined as a state of abnormally elevated arousal, affect, and energy level. During a manic episode, an individual will experience rapidly changing emotions and moods, highly influenced by surrounding stimuli. Although mania is often conceived of as a "mirror image" to depression, the heightened mood can be dysphoric as well as euphoric. As the mania intensifies, irritability can be more pronounced and result in anxiety or anger.

Dysthymia ( ), known as persistent depressive disorder (PDD) in the DSM-5-TR and dysthymic disorder in ICD-11, is a psychiatric condition marked by symptoms that are similar to those of major depressive disorder, but which persist for at least two years in adults and one year among pediatric populations. The term was introduced by Robert Spitzer in the late 1970s as a replacement for the concept of "depressive personality."

Anhedonia is a diverse array of deficits in hedonic function, including reduced motivation or ability to experience pleasure. While earlier definitions emphasized the inability to experience pleasure, anhedonia is currently used by researchers to refer to reduced motivation, reduced anticipatory pleasure (wanting), reduced consummatory pleasure (liking), and deficits in reinforcement learning. In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), anhedonia is a component of depressive disorders, substance-related disorders, psychotic disorders, and personality di

Catatonia is a neuropsychiatric syndrome which is most commonly seen in people with underlying mood disorders, such as major depressive disorder, or psychotic disorders, such as schizophrenia. People who have catatonia exhibit abnormal movement and behaviors that vary from person to person and may fluctuate in intensity within a single episode.

Dysphoria (; ) is a profound state of unease or dissatisfaction. It is the semantic opposite of euphoria. In a psychiatric context, dysphoria may accompany depression, anxiety, or agitation.

Hospitalism (or anaclitic depression in its sublethal form) 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.

S100 calcium-binding protein A10 (S100A10), also known as p11, is a protein that is encoded by the S100A10 gene in humans and the S100a10 gene in other species. S100A10 is a member of the S100 family of proteins containing two EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells. They regulate a number of cellular processes such as cell cycle progression and differentiation. The S100 protein is implicated in exocytosis and endocytosis by reorganization of F-actin.

Pseudodementia (otherwise known as depression-related cognitive dysfunction or depressive cognitive disorder) is a condition that leads to cognitive and functional impairment imitating dementia that is secondary to psychiatric disorders, especially clinical depression. Pseudodementia can develop in a wide range of neuropsychiatric disease such as depression, schizophrenia and other psychoses, mania, dissociative disorders, and conversion disorders. The presentations of pseudodementia may mimic organic dementia, but are essentially reversible on treatment and doesn't lead to actual brain degene
