What does unhinged mean?
Unhinged is chiefly an adjective meaning mentally or emotionally unstable, irrational, or so disturbed that normal self-control seems to have broken down. It often conveys a stronger and more dramatic impression than simply “upset”: “he seems completely unhinged” suggests someone whose judgment or behavior has become unpredictable. The word can also describe a situation or system that is wildly unstable or beyond control. Less commonly, it retains a literal sense of being detached from its hinges, and “unhinge” can mean removing the hinges from a door or gate. The word is used in both British and American English and is generally informal, though its figurative meaning is well established. Figuratively, the image is that of something securely fastened suddenly coming apart. This makes “unhinged” vivid for emotional collapse, frantic agitation, and loss of rational control, while also giving it a memorable connection to its literal mechanical origin.
Mentally or emotionally unstable and no longer in control of one's thoughts or behavior; wildly irrational or agitated.
"He was unhinged with grief after the accident."
Common in informal usage; often stronger and more dramatic than simply “distressed” or “upset.”
Remove the hinges from an object; figuratively, destabilize or unsettle something.
"The crew unhinged the gate and carried it away."
The literal meaning is now less common than the figurative meaning.
Originally, to unhinge a door was to remove its hinges; the figurative sense imagines a person's sanity as something similarly knocked loose.

Where does unhinged come from?
Unhinged was formed by adding the prefix un- and the participial ending -ed to hinge, paralleling the verb unhinge. Unhinge literally means to remove or detach the hinges from an object. Its figurative use developed by extension, suggesting a person whose mental or emotional stability has been similarly disrupted. The related forms hinge, hinged, and hinges belong to the same word family.

How unhinged is actually used
The figurative sense is common in informal speech and writing and can be deliberately hyperbolic. It is equally established in British and American English. When describing actual mental illness, less clinical wording may be more appropriate.
