Mental Disability!Dean

At Bay - http://honeylocusttree.livejournal.com/880.html

Summary: Dean Winchester is a functioning schizophrenic. Except when he's not. (AU)

Deaf!Dean

Pity, Sympathy, and People Discussing Me - http://sw0rdy.livejournal.com/21415.html

Summary: Dean's comments seem to indicate it's only just hit him that he has a permanent, life-changing injury and Sam knows he was right to worry that his brother seemed to be taking to his new situation a little too easily. Trust a girl to be his undoing.

Mute!Dean

Like a Bell Through the Night - http://roque-clasique.livejournal.com/144394.html

Summary: At first, Dean was all eager determination, spending hours a day on the exercises his neurologist and speech therapist had suggested: speaking to himself in a mirror, speaking slowly, speaking one word at a time, practicing the sounds of the alphabet, and even meditating.

My Life's Come off Its' Tracks - http://mimblexwimble.livejournal.com/90454.html

And Now for Something Completely Different - http://roque-clasique.livejournal.com/17153.html

Summary: Something is wrong with Dean...

The Empty Man - http://legoline.livejournal.com/624731.html

Summary: Sam managed to get Dean out of the deal. But six months after Dean's year should have been up, Sam and Dean still have to deal with the aftermath.

If a wip story is okay
you have a Dean with mental imparment (hurt!dean) here.

No Promises (http://missnegreenwood.livejournal.com/6725.html) 7 Chapters

Summary: Saving his little brother from being crushed under a gravestone puts Dean under it instead. It becomes a fight for Dean's life and it turns out to never be the same again.

It's not betad or finished because of a writes block.

The Final Concussion 'Verse (http://etoile-etiolee.livejournal.com/6049.html) by etoile_etiolee has a seriously brain damaged Dean due to having one concussion too many.

I really like this 'verse. She doesn't cut any corners with a disability like this one, either, so be ready.

Check out my general disability (http://pinboard.in/u:rbmifan/t:fandom:_Supernatural/t:misc%253A_Disability_-_All) tag on pinboard. The vast majority of links are about Dean.

Physically Disabled Dean - This Christmas Day (http://tolakasa.livejournal.com/2388.html)
Summary: Happy endings are never quite what you expect them to be.

Amnesia Dean - I See the Moon (http://kaylennz.livejournal.com/4828.html)
Summary: Sam had known how Dean felt about him when he'd left for Stanford. His own feelings weren't so clear. He'd needed time away from it all, hunting, his father, and especially Dean. It took him five years and a degree he hadn't planned on to realize there was only one person he wanted to share his life with. He'd never considered the possibility that Dean would move on without him...or that something could happen that would erase him from his brother's life completely.
