Are treatments in neurology really advancing? Everyone keeps saying so

Seems like everywhere on the medical side of the internet you turn these past couple years there's a neurologist or neuroscientist reminding other medical-adjacent people that we're living in "exciting times" because treatment options for long-term neurological conditions have rapidly advanced and neurologists don't just passively watch patients deteriorate anymore (which i don't think was ever very accurate).

I'm not doubting at all, i'm just interested in the field as a student and would like more details. Any info would be appreciated. How much are they advancing? How fast? Any examples?

Thanks in advance !!
