Are disorders such as depression and bipolar related to the myelin sheath?

I know that a thinner myelin sheath is related to autoimmune diseases such as MS. Although I would like to know if it is related to personality disorders as well.
What?!? I wanted a real scientific answer! Don't waste my time with that! Yes I believe there is always more to it but really?? I was excited to find an answer now I'm pissed.

No it isn't. First, Depression and Bipolar are not personality disorders. They are Affective disorders meaning that there is a physical cause. Personality disorders (like Borderline) are learned patterns of behavior that do not have a physical cause.

Depression and Bipolar are a dysfunction of the chemical messengers in the brain... the chemicals that pass from one nerve to another. There may be too much or too little or the chemicals themselves are defective...... No one really knows for sure but no it is not related to demyelination.

However..... having a chronic illness like MS can cause depression (but not Bipolar).... but it is related to the stress caused by the illness and not a part of the illness itself.  (+ info)

Is bisexuality and personality disorders somehow related?

Is bisexuality and personality disorders somehow related? The reason why I ask is because I've dated a few girls who had borderline personality disorder and bipolar disorder. They were both extremely promiscuous, which is why i'm not with them anymore, and were very much into girls. They were all bisexual, but it seemed to me that a lot of them were more into girls than guys. They were all messed up in the head with their disorders and were always promiscuous and wanting to make out with girls all the time. Is there some relationship between personality disorders and bisexuality?

Bisexuality is highly correlated with borderline personality disorder specifically. BPD is characterized by identity disturbance: markedly and persistently unstable self-image or sense of self. Gender identification is one avenue in which identity disturbance presents.

One study found that 57% of consecutive male patients with borderline personality disorder who presented for psychiatric treatment at two distant geographic sites were homosexual. Homosexuality was 10 times more common among the men and six times more common among the women with borderline personality disorder than in the general population.

The above is in no way a judgment against bisexuality or homosexuality. Ambiguous or unstable gender identity is a benign symptom of the disorder and not a motivation for treatment.

The promiscuity aspect is of course less benign. Both disorders are characterized by volatile mood swings and inappropriately outgoing behavior. Borderline personality disorder is characterized by all-or-nothing thinking. An erotic target may be viewed as extremely attractive, and due to instability of perceptions, a former target may be suddenly devalued. Adding in a lack of a sense of boundaries, you have a formula for promiscuity. I haven't found any sources on the incidence of such behavior among borderlines and bipolars, so just because there's a formula there doesn't mean there's a high incidence of acting on it. So I'm hesitant to say this is a characteristic of either disorder. Given that it is happening in a subject, I would tend to attribute it to the disorder.

Bisexual women tend to lean more toward an attraction to men than women.  (+ info)

Is there any truth in the views of some neurosurgeons that all behavioural disorders related to brain only?

Some neuro surgeons argue that all mental diseases like depression, psychoses, neurosis and other psychological disorders are due to some problems in brain only but no where related to mind.
In India, most of the neurosurgeons think they can cure all psychiatric disorders and seldom refer patients to psychiatrists.

I agreed to some degree, but many behavioural disorders are also defined by the culture in which one lives, socio economic status and roles that have to be assumed. Psychic trauma i.e behavioral disorders can ;also be the product of physical and mental cruelty. None the less there can be changes in the cerebral make up, as a result of depression, and even as a result of positive response to treatment, so the problem is a complex one. However it is not correct to ascribe single symptoms or etiology for behaviour disorders to unitary causation  (+ info)

What is the best medicine for balance disorders,I think its related to the inner ear because I have tinnitus.?

I need to know what is the best medicine for balance disorders and I think its because of Meniere's disease because of tinnitus.
Thank you

There are various options for treating balance disorders. One option includes treatment for a disease or disorder that may be contributing to the balance problem, such as ear infection, stroke, or multiple sclerosis. Individual treatment will vary and will be based upon symptoms, medical history, general health, examination by a physician, and the results of medical tests. Most types of balance disorders will require balance training, prescribed by a physiotherapist.

[edit] BPPV
Benign Paroxysmal Positional Vertigo (BPPV) is caused by misplaced crystals within the ear. Treatment, simply put, involves moving these crystals out of areas which cause vertigo and into areas where they do not. A number of exercises have been developed to shift these crystals. The following article explains with diagrams how these exercises can be performed at the office or at home with some help: [3] The success of these exercises depends on them being performed correctly.

The two exercises explained in the above article are:

The Brandt-Daroff Exercises, which can be done at home and have a very high success rate but are unpleasant and time consuming to perform.
The Epley's exercises[3] are often performed by a doctor but can be performed at home. Various devices are available for home BPPV treatment. [4]

[edit] Ménière's disease
Diet: Dietary changes such as reducing intake of sodium (salt) may help. For some people, reducing alcohol, caffeine, and/or avoiding nicotine may be helpful. Stress has also been shown to make the symptoms associated with ménière's worse
Beta-histine (Serc) is available in some countries and is thought to reduce the frequency of symptoms
Diuretics such as hydrochlorohyiazide (Diazide)have also been shown to reduce the frequency of symptoms
Aminoglycoside antibiotics (gentamicin) can used to treat Ménière's disease. Systemic streptomycin (given by injection) and topical gentamicin (given directly to the inner ear) are useful for their ability to affect the hair cells of the balance system. Gentamicin also can affect the hair cells of the cochlea, though, and cause hearing loss in about 10% of patients. In cases that do not respond to medical management, surgery may be indicated.
Surgery for meniere's disease is a last resort  (+ info)

How closely is Veganism related to eating disorders like anorexia?

I notice that the Vegans are mostly very young, and are controlling their diet more for fear of weight than anything else.
It makes me think Vegan is just a PC term for bulimia/anorexia.
The primary features of both anorexia and bulimia are that they are control driven behaviour. Study after study comes up with this.
Sorry but when I read answers from Y!A Vegans they are anorexic and bulimic style asnswers.
It is all about control.
Worms? Who said anything about worms? Oddly enough you can get them from salads too.

you obviously don't know too many vegans

what worms??  (+ info)

What is the correlation between substance abuse and eating disorders?

I am trying to find a research question.

I think the confusion arises because a lot of substance abuse results in appetite suppression, and the person gets diagnosed as having an eating disorder, when they haven't got an eating disorder at all.  (+ info)
