Researchers now sometimes use the terms "math dyslexia" or "math learning disability" when they mention the condition. Cognitive disabilities specific to mathematics were originally identified in case studies with patients who experienced specific arithmetic disabilities as a result of damage to specific regions of the brain. More commonly, dyscalculia occurs developmentally as a genetically linked learning disability which affects a persons ability to understand, remember, or manipulate numbers or number facts (e.g., the multiplication tables). The term is often used to refer specifically to the inability to perform arithmetic operations, but is also defined by some educational professionals and cognitive psychologists such as Stanislas Dehaene and Brian Butterworth as a more fundamental inability to conceptualize numbers as abstract concepts of comparative quantities (a deficit in "number sense"), which these researchers consider to be a foundational skill upon which other mathematics abilities build. Symptoms of dyscalculia include the delay of simple counting, inability to memorize simple arithmetic facts such as adding, subtracting, etc. There are few known symptoms because little research has been done on the topic. Etymology
The term dyscalculia dates back to at least 1949.Dyscalculia comes from Greek and Latin and means "counting badly". The prefix "dys-" comes from Greek and means "badly". The root "calculia" comes from the Latin "calculare", which means "to count"; it is also a cognate of "calculation" and "calculus". See also

Bleeding disorder
Women with a bleeding disorder may be prone to more excessive bleeding. A hematologic work-up should discover the cause. Other
On occasion an ovarian cyst can rupture and give rise to internal hemorrhage. This may occur during ovulation or as a result of endometriosis. If the pregnancy test is positive, consider pregnancy related bleeding (see obstetrical hemorrhage), including miscarriage and ectopic pregnancy. Diagnosis
A history will establish if the condition is acute or chronic, and if external circumstances are involved. A gynecologic examination is usually complemented by a gynecologic ultrasonography. A blood count determines the degree of anemia and may point out bleeding problems. The pregnancy test is important, particularly as bleeding in early pregnancy presents as gynecological hemorrhage and ectopic pregnancy can be fatal. Diagnosis is broadly classified into supportive and definitive investigations:

Supportive
Complete blood count to assess degree of anemia. Ultrasonography to rule out uterine lesions, PID. Definitive
Pregnancy test for those who are not yet post menopausal mandatory. Speculum examination to take samples for pap smear. Dilation and curettage to get samples for histology and also control the bleeding if associated with abortion. Colposcopy. Definition
Menstruation occurs typically monthly, lasts 3–7 days, and involves up to 80 ml blood. Bleeding in excess of this norm in a nonpregnant woman constitutes gynecologic hemorrhage. In addition, early pregnancy bleeding has sometimes been included as gynecologic hemorrhage, namely bleeding from a miscarriage or an ectopic pregnancy, while it actually represents obstetrical bleeding. However, from a practical view, early pregnancy bleeding is usually handled like a gynecological hemorrhage.
