It's also a bit weird that the term 'gaslighting' has recently become so mainstream that it is beginning to be used as a synonym for "invalidating symptoms", rather than the narrower original definition of "convincing someone they are mentally ill when they are not"...
Another term that has recently entered the mainstream is "brain fog".
Unfortunately, people are starting to use it as a synonym for "simple forgetfulness", so it looks like we now have to move on to more specific terminology for ourselves such as "cognitive dysfunction".
Yes. Endogenous Depression. Not caused by an outside event ie traumatic event. Biological in origin.
That's another term that may have changed meaning once it went from clinical to mainstream.
Although the word "depression" had been used as a synonym for "sadness" for some time, the clinical sense (pre-1980) often referred to an observed lack of activity or motivation of an individual. Because it implicated mental illness, it was not talked about.
In the 1980s people started to talk openly about suffering from clinical depression, which represented a change in social attitudes that has been attributed to both the publication of the DSM-IV and the advent of Prozac, although other factors may have been involved.
Then the clinical term "depression" went mainstream and people started to confuse the clinical term with "sadness". And here we find ourselves...
EDIT: I fact-checked what I had written and I made a few corrections.
