What r/dementia Is For

This community is for information and support for people dealing with dementia. It's a place where dementia patients and their families can connect and feel less alone. The description mentions several common forms of dementia including Alzheimer's disease, vascular, frontotemporal, Lew Body, and semantic dementia.

Rules That Matter Before Posting

This community displayed no rules on its public rules page. But the public description says self promotion, solicitation, and AI created content are not allowed.

What To Post

If you're a founder doing respectful Reddit marketing, your options here are extremely limited. You can't promote, solicit, or share AI content. The only honest path is to participate as a human being, sharing genuine support or information without any link, pitch, or brand mention. If your product is relevant, it should only come up naturally in conversation if someone asks. And even then, be careful. This is a support space first, not a marketing channel.

What To Avoid

Do not post any self promotion. Do not solicit users. Do not share AI created content. These bans are in the public description and the policy brief confirms they are enforced to keep the space safe.
