Different societies or cultures, even different individuals in a subculture, can disagree as to what constitutes optimal versus pathological biological and psychological functioning.
Research has demonstrated that cultures vary in the relative importance placed on, for example, happiness, autonomy, or social relationships for pleasure.
Likewise, the fact that a behavior pattern is valued, accepted, encouraged, or even statistically normative in a culture does not necessarily mean that it is conducive to optimal psychological functioning.
People in all cultures find some behaviors bizarre or even incomprehensible.
But just what they feel is bizarre or incomprehensible is ambiguous and subjective.
These differences in determination can become highly contentious.
Religious, spiritual, or transpersonal experiences and beliefs are typically not defined as disordered, especially if widely shared, despite meeting many criteria of delusional or psychotic disorders.
Even when a belief or experience can be shown to produce distress or disability—the ordinary standard for judging mental disorders—the presence of a strong cultural basis for that belief, experience, or interpretation of experience, generally disqualifies it from counting as evidence of mental disorder.
The process by which conditions and difficulties come to be defined and treated as medical conditions and problems, and thus come under the authority of doctors and other health professionals, is known as medicalization or pathologization. 
Pathology is the precise study and diagnosis of disease.
"Pathologization", to pathologize, refers to the process of defining a condition or behavior as pathological, e.g.
pathological gambling.
Pathologies (or pathoses) is synonymous with diseases.
The suffix "path" is used to indicate a state of disease, and may be used to indicate psychological (e.g.
psychopath) or physical disease (e.g.
cardiomyopathy).
A physician practicing pathology is called a pathologist.
Pathology addresses four components of disease: cause/etiology, mechanisms of development (pathogenesis), structural alterations of cells (morphologic changes), and the consequences of changes (clinical manifestations).
Pathology is further separated into divisions, based on either the system being studied (e.g.
dermatopathology) or the focus of the examination (e.g.
forensic pathology and determining the cause of death).
