Birth defects have many causes and currently, are the leading cause of death for infants in the first year of life. Some of the causes of birth defects include genetic or chromosome problems. Exposure of the mother to rubella or German measles during pregnancy, or using drugs or alcohol during pregnancy. The treatment for birth defects depends upon the condition of the effected child.
Hearing loss (deafness) may be present at birth or it may manifest later in life. Deafness may be genetic or due to damage from noise. Treatment of deafness depends upon its cause. Sensorineural hearing loss can be caused by conditions affecting the: cochlea, eighth cranial nerve, spinal cord, or brain. Examples of conditions that can lead to sensorineural hearing loss include: Meniere's disease, noise-induced hearing loss hearing loss of aging (presbycusis), nerve injury from syphilis, hearing loss of unknown cause (idiopathic hearing loss), nerve tumors, and drug toxicity (such as aspirin and aminoglycosides).
Genetic Diseases (Disorder Definition, Types, and Examples)
The definition of a genetic disease is a disorder or condition caused by abnormalities in a person's genome. Some types of genetic inheritance include single inheritance, including cystic fibrosis, sickle cell anemia, Marfan syndrome, and hemochromatosis. Other types of genetic diseases include multifactorial inheritance. Still other types of genetic diseases include chromosome abnormalities (for example, Turner syndrome, and Klinefelter syndrome), and mitochondrial inheritance (for example, epilepsy and dementia).
American Sign Language (ASL) is a complete, complex language that employs signs made with the hands and other movements, including facial expressions and postures of the body. No one form of sign language is universal. For example, British Sign Language (BSL) differs notably from ASL. Different sign languages are used in different countries or regions.
