What are the 5 developmental disabilities?

Examples of developmental disabilities include autism, behavior disorders, brain injury, cerebral palsy, Down syndrome, fetal alcohol syndrome, intellectual disability, and spina bifida. For more information, see the Developmental Disabilities Assistance and Bill of Rights Act of 2000.

Can abnormal prenatal development be corrected?

Summary: Researchers have found the first direct evidence that early embryos with genetic abnormalities can correct their faults as they develop, marginalizing cells with an incorrect number of chromosomes, while allowing the growth of normal cells.

What kind of abnormalities can occur during development?

These notes cover abnormalities that can occur during development ( abnormal development) often described as congenital abnormalities or birth defects.

What is the absence of an organ during embryonic development?

Absence of the physiological opening or the lumen of a (hollow) organ, or occlusion thereof. Continued existence of an organ or part of an organ that, physiologically, only exists for a limited period during embryonic development. Describes the frequent appearance of two or more malformations with an unknown shared cause.

When do developmental anomalies occur in a fetus?

During prenatal development there are “windows of time” or “critical periods”, that following exposure to teratogens can lead to developmental abnormalities (anomalies, congenital). In general, the effects for each system are more severe (major anomalies) in the earlier embryonic period during organogenesis in the first trimester.

What causes severe malformations during embryonic and fetal development?

Severe embryopathies, such as vision disorders, heart disorders, and mental impairment due to neural damage, may be caused by viruses (rubella, CMV, HSV, varicella virus, HIV virus), bacteria (syphilis from Treponema pallidum ), and protozoa (toxoplasmosis from Toxoplasma gondii ).
