Human Genetic Diseases

The main reason why genetic diseases are a cause of worry for many people is the fact that man can do little to prevent them from occurring. Genetic diseases occur because of chromosome problems. Some genetic diseases are extremely rare while others occur more often.

Some genetic diseases relate to one's reproductive health. Recent research has also shown that some genetic diseases are gender-driven, that is, they affect members of one gender only. A case in point is color blindness, which is known to affect male members of a community only.

Researchers have devised several ways of drawing ethnic, racial and demographic lines when researching on human genetic diseases. When researching the Alzheimer's disease, scientists had to rely on a previous finding, which showed that very few cases of the disease are reported among the Caucasian people.

The Alzheimer's disease can bring rather catastrophic effects to both the patients and loved ones. It affects the brain and makes the patient lose memory and psychomotor coordination. The patient loses complete control of all his bodily functions. One does not even remember to eat. If food is put into his mouth, he does not know when to chew and when to swallow. Such patients require special care, often in a nursing home. Majority of people who are affected are over sixty years.

DNA tests are always helpful in determining if any member of the family is a carrier of a dominant gene. Some genetic diseases are caused by dominant genes. In some cases, recessive genes also cause genetic disorders. In families where the genetic disorders are caused by a dominant gene, if the parent has the disease, the sibling has a 50% likelihood of suffering from the same disease at some point in life.

The process of diagnosing genetic disorder is very complicated. As if that is not enough, one has to take care of the patient both financially and psychologically. This might drain a family's financial resources. It can also make one marriage partner feel emotionally detached. Help from third parties would be very much appreciated.

Many support groups for people who suffer from genetic disorders have been set up across the country. A person who suffers from a genetic condition can reap many benefits by becoming a member of such a group. One can get to know how to pursue treatment. One can get to regain a feeling of belonging after depressive moments especially immediately after diagnosis.
