The disease occurs worldwide, but is most prevalent in Japan, the Middle East, and in the Mediterranean region. There is a wider prevalence among males than females in a ratio of two to one.
Sturge-Weber syndrome is a sporadic disease that is found throughout the world, affecting males and females equally.
Males are affected with Bassen-Kornzweig syndrome with greater frequency (70%) than girls, which is uncharacteristic in most autosomal recessive conditions.
No, as it is a chromosomal disorder I am fairly sure it would affect all demographics equally.
Have your Doctors considered Neuro-Behcets as a diagnosis? It is quite rare and usually is found in Middle Eastern people, along the "old silk Highway", But Americans and English people get it too. I am very white skinned and I have Neuro-Behcets. Do you have a history of Oral Canker sores OR Genital Ulcers? (in Females on the inside of the Labia. On Males, on the Scrotum and some times the Penis.) Neuro-behcets can cause very, very, severe headaches and Back Aches. Even "Aseptic Meningitis", and Gastro-Intestinal Ulcers. And many other skin problems. The Neuro-Behcets Brain Lesions usually appear in the deep white matter of the FRONTAL LOBE of the brain. Have you had an M.R.I with and without contrast material yet? If not you should ask your doctor to perform one. Neuro-Behcets can cause Frontal Lobe damage and Mental Problems - all the way to "Dementia". Persons with Neuro-Behcets can be, "Mentally and/or Physically Dependent on others" before they die. There is no test FOR it. Ruling out M.S., Rhumatoid Arthritis , Lupus, etc., are some of the first steps to a diagnosis of Behcets or Neuro-Behcets. The Bla-52 gene test, may show up as a possible Positive indicator. Also, a "Positive Pathergy" Test, is positive in about 50% of Behcets patients. (I am very "reactive" when Blood is drawn for Lab Tests, about 24-48 hour later, I have large red "welt" like an ant bite , where ever the needle punctured my skin.) This is when some one reacts with small to large red bumps when "Pricked" with sterile needles on the inside of the fore arm. I suggest you go to the American Behcets Society website and see if all, or some of the symptoms match up with your symptoms. (When I went to the site - There I was! All of those symptoms were mine.

Carpal tunnel syndrome is more common in women than in men, perhaps because the carpal tunnel generally has a smaller cross section in women than in men.
Down syndrome occurs in people of all races; however, studies have shown that people of Caucasian descent have a higher incidence of Down syndrome compared to other races. This is likely due to differences in genetic makeup and population demographics.
As with other types of spinal cord injuries, men are more frequently affected by central cord syndrome than women. In younger individuals (secondary to trauma) or in older individuals (secondary to spondylosis).
Down syndrome occurs in approximately 1 in 700 live births. Given California's population of around 39 million, the number of individuals with Down syndrome can be estimated to be around 0.14% of the population. However, exact percentages can vary based on specific demographics and reporting methods.
