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.

Mysophobia (from Ancient Greek μύσος (músos), meaning "pollution", and φόβος (phóbos), meaning "fear"), also known as verminophobia, germophobia, germaphobia, bacillophobia and bacteriophobia, is a pathological fear of contamination and germs. It is classified as a type of specific phobia, meaning it is evaluated and diagnosed based on the experience of high levels of fear and anxiety beyond what is reasonable when exposed to or in anticipation of exposure to stimuli related to the particular concept (in this case germs or contamination). William A. Hammond first coined the term in 1879 when d

The striatum (: striata) or corpus striatum is a cluster of interconnected nuclei that make up the largest structure of the subcortical basal ganglia. The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia.

Scrupulosity is the pathological guilt and anxiety about moral issues. It is personally distressing, dysfunctional, and often accompanied by significant impairment in social functioning. It is typically conceptualized as a moral or religious form of obsessive–compulsive disorder (OCD). The term is derived from the Latin scrupus, a sharp stone, implying a stabbing pain on the conscience. Scrupulosity was formerly called scruples in religious contexts, but the word scruple now commonly refers to a troubling of the conscience rather than to the disorder.

Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) is a controversial hypothetical diagnosis for a subset of children with rapid onset of obsessive–compulsive disorder (OCD) or tic disorders coming immediately after a Streptococcus infection. Symptoms are proposed to be caused by group A streptococcal (GAS), and more specifically, group A beta-hemolytic streptococcal (GABHS) infections. OCD and tic disorders are hypothesized to arise in a subset of children as a result of a post-streptococcal autoimmune process. The proposed link between infection

Apeirophobia () (from ) is the specific phobia of infinity, eternity, endlessness, or the uncountable and is also known as the fear of infinity, the fear of eternity, or the fear of endlessness, causing discomfort and sometimes panic attacks from intrusive thoughts of the infinity. It normally starts in adolescence or earlier and it is currently not known how it normally develops over time. Apeirophobia may be caused by existential dread about eternal life or oblivion following death. Due to this, it is often connected with thanatophobia (the phobia of death), chronophobia (the phobia of time

thumb|Plyushkin, drawing by Alexander Agin (1846-1847) Stepan Plyushkin () is a fictional character in Nikolai Gogol's novel Dead Souls. He is a landowner who obsessively collects and saves everything he finds, to the point that when he wants to celebrate a deal with the protagonist Chichikov, he orders one of his serfs to find a cake that a visitor brought several years ago, scrape off the mold, and bring it to them. At the same time, his estate is incredibly inefficient; the cut wheat rots on the ground and any potential income is lost.
