What does alienism mean?
Alienism is a noun with two principal senses, both now largely historical. Its dominant meaning is the branch of medicine devoted to mental illness — essentially what we today call psychiatry. The word derives from the older notion that people suffering from mental disorder were 'alienated' from their own minds, and physicians who practised this specialty were known as alienists, a title still encountered in nineteenth-century fiction and histories of the asylum. A second, rarer sense refers to the legal or social condition of being an alien, meaning a foreigner or non-citizen. Both senses have fallen out of everyday use: the psychiatric one was displaced by modern terminology during the twentieth century, while the legal one survives only in specialized contexts. Alienism therefore appears chiefly in academic, literary, or historical writing, where it lends period flavour and precision when discussing how earlier eras understood and treated mental illness.
The study and treatment of mental illness; the historical precursor to modern psychiatry.
"She wrote her dissertation on alienism and the rise of the Parisian asylums."
This sense is archaic; 'psychiatry' is the standard modern equivalent.
The state or condition of being an alien, especially under law.
"His prolonged alienism prevented him from voting in national elections."
Rare and largely obsolete; 'alienage' is the more usual modern term.
The plural is uncommon but grammatically regular; it may refer to multiple doctrines, systems, or instances of alienist practice.
"The conference compared competing alienisms across nineteenth-century Europe."
Before 'psychiatrist' caught on, doctors who treated the mentally ill were called 'alienists' — because their patients were thought of as 'aliens' from their own minds.

Etymology of alienism
Alienism derives from the Latin root 'alienus', meaning 'belonging to another' or 'foreign', which also gives English words such as alien, alienate, and alienation. The psychiatric sense arose in France in the late eighteenth and early nineteenth centuries, associated with pioneers like Philippe Pinel and Jean-Étienne Dominique Esquirol, whose field was called médecine mentale or aliénisme; English borrowed the term via French. The legal sense of alienism, denoting the status of an alien, developed independently from the same Latin root through the legal vocabulary of nationality and citizenship.
How alienism is actually used
Alienism is an archaic or historical term. In its psychiatric sense it survives mainly in scholarly writing about the history of medicine, where 'alienist' denotes pre-twentieth-century practitioners of mental medicine. Its legal sense relating to foreigner status is rare and largely obsolete.
