When the mother has high blood pressure (hypertension ) or blood poisoning (toxemia), the flow of oxygen to the fetus may be reduced, causing brain damage and mental retardation.
Stem cell research has the potential to help with mental retardation by better understanding the underlying causes of intellectual disabilities and developing new treatments. However, more research is needed to fully understand how stem cells could be used to improve outcomes for individuals with mental retardation.
Downs syndrome is caused by having 3 copies, trisomy, of chromosome 21 in your DNA. This can be random, causes are often unknown although it is associated with increased maternal age. Symptoms include characteristic facial features, varying degrees of mental retardation/learning difficulties, a happy and sociable disposition, increased susceptibility to certain heart conditions and other medical conditions and many others. Best to google it for a very quick overview.
Down syndrome is the genetic disorder characterized by varying degrees of mental retardation. It is caused by the presence of an extra copy of chromosome 21. Symptoms of Down syndrome can vary widely, but intellectual disability is a common characteristic.
It may be necessary to consult with a neurologist or neuropsychologist in the diagnosis of mental retardation when there are complex neurological or cognitive issues that require specialized assessment. They can provide valuable insights into brain function and help identify underlying causes or contributing factors to the individual's cognitive impairments. Working together, they can offer a comprehensive evaluation and treatment plan for individuals with mental retardation.
Chromosome mutations such as aneuploidy (caused by trisomy or monosomy of specific chromosomes), microdeletions (e.g. Cri du Chat syndrome), and translocations (e.g. Fragile X syndrome) are known to be associated with mental retardation or intellectual disabilities. These mutations can disrupt normal gene function and development in the brain, leading to cognitive impairments.
Maternal infections and such illnesses as glandular disorders, rubella, toxoplasmosis, and cytomegalovirus (CMV) infection may cause mental retardation
The two conditions are not at all related. Autism does not cause mental retardation.
Autism and mental retardation are two separate conditions, but they can co-occur in some individuals. Not all people with autism have mental retardation, and not all people with mental retardation have autism. It is important to recognize and address each condition separately, as they have different characteristics and require different approaches to support and intervention.
Overstudy does not cause mental retardation.
Maternal infection at conception or within the first two weeks of pregnancy may lead to hearing and vision loss and mental retardation.
Maternal infections and illnesses such as glandular disorders, rubella, toxoplasmosis, and cytomegalovirus infection may cause mental retardation.
TThere are quite high as it comes in different types of mental retardation.
Exposure to lead can also cause mental retardation.
literature review on mental retardation with reference
Mental retardation has different levels. There is Mild intellectual disability; moderate intellectual disability; severe intellectual disability; and Profound intellectual disability.https://www.floridahospital.com/mental-retardation-mr/symptoms-and-signs-mental-retardation
because some ppl are born with birth defects like mental retardation
About one-third of individuals with CP have moderate-to-severe mental retardation, one-third have mild mental retardation, and one-third have normal intelligence.
