My mom scratches and claws her head all the time. Anxiety. We've tried everything. Just let it go or?

Could an antidepressant be considered? There are some that help with that behavior. My mother has elements of behavior such as this but since she is on so many medications I don't bring this up as she has endured surviving a septic infection and is mild mannered at least. I imagine your mother may do this out of habit rather than a skin condition.

The anxiety is what needs treatment.

Talk to her doctor about prescribing a mild anti anxiety med.

Has she been to a dermatologist?
