Which bona fide physical diseases do they treat? I'm drawing a blank, and my brain stopped working about an hour ago .... I'm going to have to take a time out shortly ....
If we're including short term physical problems, they treat seizures, which are physical. Of course i agree they're not the best treatment long term bc of their dependence forming, there are better anticonvulsant, but in emergencies they stop seizures.
They also have been found to help.some me/cfs patients a lot , probably bc of glutamate activity and they're used by some mcas doctors. Whether or not they have awful side effects long term isn't the point I was trying to make , just that psych med is a meaningless category, meds can treat psych issues and also physical problems.
Benzos are used to treat muscle spasms post surgery. This is not a disease so much as a symptom but it is very much a physical symptom, there is not a psychological reason for the muscle spasms.
I believe they can also treat tremors and dystonia and nystagmus, all usually physically caused symptoms.
Fluvoxamine is a psych med that has some antiviral activity in vitro i believe and has been used in acute covid.
Amitryptiline is a psych med, a tricyclic antidepressant, used for neuropathic pain too.
And the other way around there are many meds that were primarily used for physiological things that end up working for psychiatric diseases. For 3xample, buprenorphine has helped in some case studies of treatment resistant extreme depression . Minocycline has helped with schizophrenia.
