been reading up on psychology and the mind. it's really complex (and prolix) stuff, but there's always something interesting to keep me going. here are some of the things i've come across:
tourette's syndrome: in more extreme cases, there is a sudden onset of muscular spasm and the urge to yell and curse at anyone or anything in the surrounding area for no particular reason
factitious disorder: person craves a 'sick role' and so, pretends to have a physical or psychological condition
schizophrenia: comes in several types of which two are catatonic and paranoid. the former involves a sudden refusal to speak as well as the assumption of a rigid posture for hours or days on end. the latter results in the person being preoccupied with delusions and haunted by auditory hallucinations. (note that schizophrenia is different from the dissociative disorder commonly known as 'multiple personalities')
delusional disorders: grandiose, whereby the person has an inflated sense of self-worth that lasts for at least a month. an erotomaniac believes that s/he is deeply desired or loved by someone (usually of higher status) when in fact the person concerned has no such feelings. (sounds like a guy thing to me. heh.)
other psychotic disorders: induced psychosis whereby a close friend or relative is 'infected' by a psychotic person's delusion.
dissociative disorder: apart from the multiple personality disorder that we're all familiar with, i came across another one that's called psychogenic fugue. essentially, it is a sudden, unplanned and unexpected travel away from home or work by a person, accompanied by amnesia and then the assumption of a new identity.
impulse control disorders: there are several of which one of the most comon is trichotillomania, which is the inability of a person to stop the impulse to pull out their own hair.

'diffusion of responsibility': bystanders witnessing a crime in progress tend to think that somebody else has already made a decision about what to do and that further help is either on the way, or unnecessary. in the murder of kitty genovese in new york years ago, 38 people could have intervened to stop the murder from taking place, but nobody lifted a finger.
speech: 70% of left-hander's speech control comes from the left hemisphere, while 15% have their ability controlled by the right hemisphere. the remaining 15% rely on both hemispheres working together to speak. interestingly, 99% of right-handers use only their left hemisphere for speech. stuttering is most common in left-handed males, and one theory suggest that this is because the two hemispheres compete for control. the majority of autistic children (who tend to suffer from speech difficulties) are left-handed.
prosopagnosia: (big up to my bro here. i'm sure he knows this one well.) it's the inability to recognise faces, usually resulting from damage to or problems with the occipital lobes of both hemispheres of the brain. that's the bit right at the back of your brain. possibly if you wish you never met someone, a quick chop to the back of the head (yours or preferably, theirs) might do the trick.
neglect syndrome: results from extensive damage to the right-rear of the brain. sufferers behave as though the left side of everything does not exist, including their own body. they do not realise that they have a left arm or leg, for instance, and so men shave only the right half of their faces and women apply makeup to the right half only. they only eat what is on the right side of their plate and they are blind on the left-side of their visual fields. this condition only occurs with damage to the right hemisphere and only affects the left side of the body. the reverse does not.
narcolepsy: the condition whereby one cannot help suddenly and uncontrollably falling asleep.
cataplexy: during a moment of strong emotion, the sufferer loses all muscular control and collapses in a heap, while remaining fully concious.
stockholm syndrome: during some hostage situations, the hostage, due to the realisation that death may arrive at any moment, may grow a child-like dependence on the hostage-taker. the hostage begins to sympathise with the hostage-taker and may even fall in love. the hostage may even support the hostage-taker's motives and insist that his demands are met. if you watched 'the world is not enough', james bond found out (the hard way) that elektra king was suffering from this condition.

well, that's all for now. a long and interesting read, i hope. stay tuned for more, folks.
