| − | * Congenital malformations may involve the spinal cord, brain, meninges, calvaria or vertebral column.
| |
| − | * Abnormalities typically result from defects in neural tube development.
| |
| − | * Congenital malformations are present at or before birth, and manifest as either:
| |
| − | ** Morphological problems
| |
| − | ** Functional problems
| |
| − | *** Tend to arise as biochemical abnormalities, such as the lysosomal diseases or leukodystrophies.
| |
| − | * Causes of congenital abnormalities include:
| |
| − | ** Environmental causes
| |
| − | *** For example, these may be toxic, infectious, nutritional, or physical (e.g. radiation)
| |
| − | *** This is by far the most common cause.
| |
| − | ** Inherited traits.
