Hoarding is considered one of the least central of all OCPD diagnostic criteria.

Focusing treatment on the perfectionism aspect can be effective, as perfectionism can obstruct progress in the therapeutic pursuit (stopping or not attempting treatment because they are not doing it perfectly).

One difference between OCPD and OCD is that the obsessions in OCD are seen as irrational or unwanted, yet persist because of the disorder. People with OCPD see their obsessions as reasonable because they are consistent with the person's belief system.

OCPD is one of the most prevalent personality disorders, yet it's also one of the least researched and known about.
Strong links with OCD, eating disorders, and drug/alcohol problems.
"OCPD may therefore be best conceptualized as a disorder characterized by rigid perfectionism and poor central coherence, with other traits influencing how the disorder manifests in individual cases."
