which chromosomes does ocd effect?

As in X or Y chromosomes??  Don't know,but I do know that OCD is due in part to an imbalance of serotonin in the brain.

My husband has O.C.D.!   He is has many rituals and strange quirks, for instance:\n1) when he takes off his shoes, his laces all have to be pulled straight toward the front\n2) he must buy 5 tacos at Taco Bell even though  he is only hungry enough to eat 3\n3) when he goes to a new store where ever he parked that first time is HIS parking place for life!  And he must always drive all the way into the one infront of it so he doesn't have to back out\n4) he must wear certain color shirts each day of the week and must where only those colors on those days.  And by the way, they must be in the sequence of the rain bow!\n\nI could go on but I think you get the picture.  Are you on medication?  He is on Zoloft.  It has  changed his life.  He is very happy on it ...... and I AM SO HAPPY HE IS ON IT, TOO.  LOL  You're not alone, honey.

not necessarily.  math may just be her weak subject.  however, a lot of OCD behaviors involve counting...counting steps when you walk, etc.  it is possible that she sees numbers and has a hard time moving on to the next step because it is, for example, an odd #.  i struggled with some minor ocd.  heres an example...i would sort my m&m's by color.  i'd lay them out on the table and count them.  if there was an odd number, like 11, i would throw one out.  people often make fun of these kinds of habits and think they are quirks.  many don't realize it is something that we can't always control.  good luck to your friend...study with her to keep her mind busy and keep her brain from getting "stuck" on a number.

umm, though i'm not sure what the question really says- i think you are asking about genetic diseases involved with chromosome number, if i'm right the following stands, if not then ignore it. \nif you have less or more chromosomes than 46 you will not survive far past fertilization, at least thats what i understand- either that, or you would be a different species- unable to produce a fertile offspring with a human.\n\nHowever there is a lot of confusion around Down's syndrome. This is caused by non-disjunction of chromosomes during meiosis, and creates trisomy genotypes on chromosome 21. \n\nTrisomy and non-disjunction can also occur on chromosome 17- causing another disease, which i have momentarily forgotten the name of. sorry.

Obsessive-compulsive disorder (OCD) is a psychiatric disorder; more specifically, it is an anxiety disorder. OCD is manifested in a variety of forms, but it is most commonly characterized by a subject's obsessive, distressing, intrusive thoughts and related compulsions (tasks or rituals) which attempt to neutralize the obsessions.\n\nI have OCD and when I fight the fact that I have to do something, it stresses me out bad.  So I just do the things I have to and deal with that is how I am.

A female egg has 23 chromosomes. A male sperm has 23 chromosomes. Thus, when a sperm fertilizes an egg, the embryo has 46 chromosomes. Women have two x chromosomes, whereas males have an x and a y. Each contribute one. The woman will always contribute an x. If the man contributes an x, the child will be female. If he contributes a y, the child will be male. Abnormalities can be caused by an added or subtracted part or whole of a chromosome. For example, trisomy 21, or down dyndrome, involves an extra chromosome. Kinefelter's involves a child having an xxy genotype, rather than the normal xy for a male.

OCD sufferers are blessed with an innate ability to focus on the things that are important to them. They can drown out all other forms of input (screaming people, problems in their perosnal life) and focus on the game in front of them.

You already had good and detailed answers in here.\nAnyway as everyone had mentioned OCD stands for Obsessive Compulsive Disorder.\n\nIt is a type of anxiety that happens when there is a problem with the way the brain deals with normal worrying and doubts. Anyone with OCD worry a lot and feel afraid about bad things that could possibly happen. \n\nIt is very normal for anyone to worry every now and then but this normal worries usually go without causing any problem. When such worries become really intense and happening over and over again, it turns as OCD where the brain replays the worry thoughts and if nothing is done, the worry feeling can get worse and worse. These frequent worry thoughts are called obsessions, and the behaviors people do to try to make the worry thoughts go away are called compulsions, thus making it obsessive-compulsive  disorder. The thoughts and behaviors a person with OCD has are senseless, repetitive, distressing, and sometimes harmful, but they are also difficult to overcome. \n\nSomeone may have obsession on anything.  The obsessive worries just don't quit. The brain keeps repeating them instead of moving on to something else. No matter how much you don't want to hear it, your brain just keeps playing it back. Yelling the word "Stop!" loudly to a person with an obsessive thought is an incompatible response. Someone may have obsessions about:\n>>germs or dirt \n>>illness or injury (involving the person or someone else) \n>>coming across unlucky numbers or words \n>>things being even or straight \n>>things being perfect or just right in a certain way \n>>making mistakes or not being sure \n>>doing or thinking something bad \n\nCompulsions are ritualitic behaviors, or actions believed to let the bad feelings go away (and for a while, it often does), with fear that not doing the ritual will make something bad to happen. The more the rituals are done, the more the feelings of doing them.OCD afflicted persons know the repetition is unnecessary, but are unable to stop themselves.Afflicted individuals usually experience severe anxiety if unable to complete their rituals, though many therapies work by helping the individual learn that no catastrophe occurs when the behaviors do cease. \n\nResearch has shown that one of the most difficult problems in OCD is in getting family members to understand that the patient is unable to simply stop the behavior. Many times relatives become angry and upset when they are forced to deal with the time-consuming and unrealistic repetitive behaviors. With this background, it is no wonder that many patients do not volunteer their symptoms, and instead complain only of anxiety or depression. \n\nSome OCD compulsions:\n>>checking things over and over (such as doors, locks, or stoves and lights)\n>>recurrent intrusive thoughts of hurting oneself or one's children. \n>>lots of hand washing or showering (doing this way more than usual or having a hard time stopping) \n>>counting (like having to count 25 white cars before going into school) \n>>touching (like touching every single fence post between home and the bus stop) \n>>doing things a certain number of times (like having to try on five dresses before leaving your room) \n>>arranging things in a very particular or neat way \n>>asking the same question over and over \n>>tying and retying shoes over and over until they feel just right.\n\nOCD is a long term illness and a very disruptive illness which definite cause is still under research. Research and treatment trials suggest that abnormalities in serotonin (5-HT) transmission in the central nervous system are central to this disorder. Tke known causes which take their roles are genetics, some infectious diseases, stress, and defective interpersonal relationship. OCD should be differentiated from those being a perfectionist and being overly conscientious. \n\nIt

Not that I'm aware of. This genetic condition involves the X and Y chromosomes, and not anything else.

Yeah. Sometimes OCD is triggered by something, like a memory or occurance. It doesn't have to be constant, but it should be fairily regularily.

It is the chromosome after #2.  It is the reason why your momma dresses you funny and your daddy disowns you.

I sure do. There are basically 4 different types of chromosomal mutations:  deletions, duplications (both of which are caused by nondisjunction), inversions (a piece of the chromosome breaks off, rotates 180 degrees and then reattaches), and translocation (a piece of a chromosome breaks off and reattaches to another chromosome).

I don't think there is ever a connection with OCD. I have it, too and some of the things I consistently do are really weird. Mine is a number thing mostly.

I would go to www.ocfoundation.org to see if they have a recommendation for someone in your area.  If you are not limited to your area, I think the best person out there is Dr Bruce Hyman at www.ocdhope.com, he helped me.\n\nIt is possible to manage OCD.  \nAlso you if you can find a support group in your area through the oc foundation, that would be good too.

I know exactly what you're going through, i have ocd too. im not going to a psycologist or anything though. its like i cant stop thinking. i think the thing that usually helps me is to go out with friends, they help me feel better and keep my mind off things.

We normally have 23 pairs of chromosomes, that is, 46 chromosomes in total. When they're seen inside of a cell nucleus, they just look like similar V , X and Y shaped little dark spots, but the specialists are able to order them and know which ones belong to each pair (i.e. are homologous). They've labeled the pairs from 1 to 23 (the 23rd pair is the XX or XY sex chromosomes). \nIn Down syndrome, there is an extra chromosome. If you just looked at an image of the nucleus, you'd just count 47 chromosomes. But it has been determined that the "extra" one is a duplicate of one of the members of pair 21. \nIn the case of other duplicate chromosomes, the effects are not Down syndrome. Most cases of chromosomal duplication are lethal.
