Do आप think एल has a mental disorder?

Yea. Its called Idontgiveafuck Syndrome.

It can be contagious.

My friend and I just had a conversation about this. we think he was sexually abused as a child. he sits and stands like he's protecting himself, he has a eating, erm, disorder, I suppose. (excuse my bad english) An oral fixtation (biting/ sucking on his fingers) he doesn't seem to want to form any relashionships, and he doesn't care about how he looks. I knnow, we put way too much thought into it.

Ok, I'm not an expert when it comes to एल या Death Note, because my friend is the DN fanatic, but from what she told me and from few episodes I saw online I tend to think एल has a Schizoid personality disorder.
Schizoid personality disorder (SPD) is a personality disorder characterized द्वारा a lack of interest in social relationships, sometimes sexually apathetic, a tendency towards a solitary lifestyle, secretiveness, and emotional coldness.

I'm not an expert on those types of things, but I'm pretty sure that एल is anti-social. That means that he doesn't like being around people. :D

I myself have Asperger's syndrome though my symptoms are not as prominent as L's, I think he does in fact have a case of it though significantly worse than I do.

OCD is my best guess.

NO!!!!!!!!!!!!!!!!!!!!!! XP

NOOOOOOOOOOO!HE DOESN'T!IF HE HAS A MENTAL DISORDER THEN SO DO I,well tenchnically I have adhd,BUT THAT HAS NOTHING TO DO WITH THE MATTER!AND NOW a बिना सोचे समझे picture, WACHA!

Being autistic myself, I wouldn't be to surprised if he was as the few things about him are shared with my own.

I actually have this theory that Light and एल are just meant to be very similar in both personality and ideas of justice, however obviously, Light's way was completely to get rid of that person while L's was to simply arrest and let the authorities deal with it. I just see एल as a really calm, laid-back guy and as arrogant as Light is. Like when they where discussing the case with the yoshba group, did आप notice that एल was so arrogant he basically told them they where wrong and he wasn't there to argue and left the room completely. I'd go so far to say that they both act the same but Light's was और mentality where L's was और in the way he acted. That I think was also Light's demise and L's both where soo similar and manipulating others with ease that it was there downfall. Light and एल could get into each other's heads as well, which is why both had to be so careful. The main difference is that Light didn't care about anyone at all to obtain his goals and एल did care about the other detectives. I actually don't think एल has a disorder at all just since he had to keep his identites a complete secret so except for Watari he probably wasn't used to interacting with others outside of a computer screen.

I'm going to say it's quite likely.

आप may want to take a look at the Wikipedia page on Asperger Syndrome.

For starters, I would say he appears to have a lack of empathy, and isn't the best a socializing. Then there's the fact that he normally communicates with a different voice and uses the fancy 'L' instead of his face. He also has a tendency to put his thumb to his lips (repetitively), which isn't uncommon for people with Aspergers. He's also quite intelligent, which is common in any form of autism.

आप probably would want to look into different forms of autism (I really only know about Aspergers because I am affected द्वारा it.)

I'd say Near is also likely to have some form of autism, so if आप wanted to look into that आप could.

What an interesting टिप्पणियाँ section XD when I first saw DN, I thought "L isn't going to have many fans. We have a number of things in common and only the few people who get to know me like me--everyone else is put off द्वारा the surface anti-social awkwardness and other eccentricities." I was STUNNED to find he was not only the most लोकप्रिय character in the show, but voted the most लोकप्रिय character of an entire year's worth of anime! (or something like that) Whatever he has, I have similarities, and yes, he does have mental issues. Nothing like sexual abuse (possibly subliminal), and likely not full-blown autism anything. Narcissism is in there, unfortunately. :( But it's not so bad once आप reign it in. I could go on, but the टिप्पणी दे box is limited ^_^

He definitely has insomnia. आप can tell mostly because he never sleeps, and also आप see directly below his eyes the dark area. Though, insomnia is generally not categorized as a mental disorder, rather a physical one. He probably has a sugar-filled खाना obsession. आप see in the series that he is really never seen without cake या strawberries या some other फल या dessert.

एल has insomnia.
Insomnia is a sleep disorder that keeps आप from sleeping. एल is known for having dark bags या shadows under his eyes. This is the cause of insomnia.
Also एल Is a sweet tooth which means he eats a lot of sugary foods.

That's all my knowledge really says about his mental disorders. I do not believe there is anything else wrong with him besides his lack of sunlight which is why his skin is so light. And the way he sits is not a disorder, it's just his preferred way of sitting because it "increases his intelligence skills द्वारा 40%."

This is a VERY late answer, but I think the answer is yes. I myself have Asperger's Syndrome, and he acts A LOT like I do. People seem to think he has this because he tends to act like a child, but that's (most likely) not why. The way he always has his thumb on his lips या in his mouth is similar to what I used to do. I used to suck on two of my fingers almost constantly. And like me, he seems to always have to need to be moving. Another thing I used to do was rock back and forth whenever I was on a सोफ़ा, सोफे या in a chair. I've stopped that, but I now have a rocking chair I use when I'm at home; usually only when I'm on my laptop, thinking about anything and everything, या reading. Also, I noticed that his pupils are rather large. Due to the medications I take, my pupils are also very close to the size of my iris. Another thing is how he likes to stack things. When I was little, I used to stack everything that would stack. Especially stacking Legos into gigantic towers. I still do stack things, actually. Another thing is how he basically didn't pay attention to that Misa Misa commercial; like it wasn't even there. A lot of people think that Aspies are just asexual, which isn't true. I can't speak for everybody, but एल seems a lot like me when it comes to that. I do experience attraction to people, but it's not something आप can see clearly on my face nor will I seem to be paying attention. And yes, sometimes I'm not paying attention to it, even though it's there. A lot of the time, people with Asperger's tend to have a very little attention span unless it's something that speaks to them. For example, संगीत and history speak to me. I could spend all दिन listening to संगीत and studying the history of the world; though there are quite a few more. Anyway, before I forget what I'm supposed to be doing: I think that unless एल is particularly interested in things like that at the time, he's just going to ignore it, like I do. And आप mentioned less social behavior. Like L, I don't leave my room या my house unless I absolutely have to. People with Asperger's tend to need time alone; like to be alone. They may not always want to be alone, but will like to be alone (with या without someone they consider a true friend; like Watari is to L) और often than not. And I can see your point about inability to register social cues. The only emotions I can see are happiness, sadness, and anger. To me, everything else looks like a blank face; with no emotion at all. I also lack the ability to read body language, so I can't understand what people are trying to do या how they feel. When I first saw L, my brain went "Literally me!" because I used to look exactly like that. The hair and just omg. Another thing with Asperger's in insomnia, which I do have as well. I probably don't need to go into that, though. Anyway I'm sO SORRY IT'S SO LONG PLEASE FORGIVE MY NEED TO RABMLE!

I think he has depression? He seems to talk and act slower and और tired, and depression causes this and lack of emotion. He definitely has insomnia, which is usually caused द्वारा depression. Plus he overeats कचरा, जंक, रद्दी खाना and rarely cares for his health. Personally I deal with all of this because of my depression and anxiety.

Who knows maybe he had a screwed up childhood
