What causes congenital disabilities

The baby has other injuries in the mother's body.

Poor nutrition or premature birth.

Or the mother took certain drugs or took drugs during pregnancy.

Here's the exact answer.

Genetic factors include chromosomal aberrations and genetic mutations. The number of chromosomes is aberration, that is, the chromosomes of embryonic cells are no longer 23 pairs, such as trisomy 21, trisomy 18, and trisomy 13. Polyploidy mostly leads to early miscarriage.

Chromosomal structural aberrations can lead to congenital disorders, such as the loss of a segment of chromosome 5 that causes laryngeal hypoplasia, and the baby's crying is small, monotonous, or cat-like, called crying cat syndrome. The symptoms of gene mutations are more obvious, such as polydactyly, syndactyly, achondroplasia, dwarfism, hydrocephalus and cataracty. Some congenital diseases are not accompanied by morphological distortions and must be diagnosed by laboratory tests, such as acetonuria and hemoglobinopathies, which are also congenital diseases that should be strictly guarded against.

At present, more than 6,000 genetic diseases have been discovered, and more than 100 new genetic diseases are added every year. It involves various organs and systems of the human body and is an important cause of perinatal fetal death and congenital disability.

The only way to explain heredity is genetics, or it's when you are born where you touch your body, and babies are very vulnerable.

According to reports, in China, the vast majority of disabilities are caused by acquired factors. According to the Second National Sample Survey of Persons with Disabilities, the proportion of disability caused by congenital factors, and the proportion of disability caused by acquired factors is also unknown or other reasons). According to the World Health Organization, at least 50% of disability can be controlled or delayed using existing technologies.

At present, there are 2.21 million disabled people in our province, and as long as effective preventive measures are taken and systematic services are provided, the number of people with disabilities can be reduced and the degree of disability can be reduced. August 25 this year is the first National Disability Prevention Day. The reporter learned from the Provincial Disabled Persons' Federation that according to the implementation plan of the "National Disability Prevention Action Plan (2016-2020)" issued by our province, by 2020, the province's disability prevention work system and prevention and control network will be more perfect, the awareness and ability of disability prevention in the whole society will be significantly enhanced, and the incidence of comparable disability will be lower than the national average.

Congenital disability comes from birth.

Diseases such as abnormal or defective appearance and structure, dysfunction, metabolic abnormality, mental retardation, etc., at the time of origin or after birth. Congenital disabilities** are caused by diseases and injuries that occur in the mother's womb and in the birth canal during birth. Some of these diseases and injuries are visible or recognizable to the naked eye at birth, and some do not manifest themselves until months and years after birth.

Acquired disability is a disability that is healthy at birth but is caused by an accident or illness after birth.

To put it simply: the disease brought from the mother's womb is called congenital disability. Diseases caused by various factors after birth are called acquired disabilities.

There are more than 85 million disabled people in China, accounting for the proportion of the total population. The causes of disability include population aging, chronic diseases, accidental injuries, birth defects, etc. However, among the various causes of disability, acquired factors are the main factors of disability, and the proportion of people who are disabled due to congenital factors and the number of people who are disabled due to acquired factors account for the proportion of those who are disabled.

Common causes of disability are genetic, developmental, traumatic, disease, environment, behavior, etc., in China, the vast majority of disability is caused by acquired factors, according to the statistics of the second national sample survey of the disabled, congenital disability due to nasty, acquired disability due to acquired factors, unknown cause or other factors to disability.

The main causes of disability can be summarized into three main areas, namely, genetic and developmental disability, trauma and disease disability, and environmental and behavioural disability. The three interact with each other to create congenital disability and acquired disability or acquired disability.

According to the World Health Organization, about 15% of the world's population currently suffers from disability, and this number is growing due to demographic changes, including population ageing and the increase in chronic diseases worldwide. One may wonder, what are the causes of a person's disability? Hunan Expert Technology understands that there are mainly these.

1. Inbred marriage and childbearing.

Disorders can lead to almost all categories of disability. According to a survey conducted in six provinces in China, 80 percent of peasants do not leave the county, 50 do not leave the township, and 30 do not leave the village, resulting in many congenital disabilities. Most of the disabled children in China are disabled by congenital factors.

The proportion of congenital disability in children with various types of disabilities is as follows: visual disability; Intellectual disability accounted for; 47 with hearing or speech impairment; Physical disability accounted for. According to statistics, more than 300,000 children born with congenital diseases are born in China every year, of which 68,000 are children with cerebral palsy.

2. Infectious diseases: such as Japanese encephalitis, encephalitis, ankylosing spondylitis, mumps, etc., which can cause intellectual, physical, and reproductive disabilities. Diseases during pregnancy, such as rubella, intrauterine infection, pre-eclampsia disease, syphilis, AIDS, etc.

Chronic diseases and geriatric diseases, such as cardiovascular and cerebrovascular diseases, chronic obstructive pulmonary disease, diabetes, rheumatoid arthritis, tumors, etc. can lead to different types of disabilities.

3. Drug-induced disability.

The more common ones are drug-induced deafness, drug-induced peripheral neuritis, etc. At present, it is known that there are dozens of drugs that can cause deafness, such as streptomycin, gentamicin, etc., and the proportion of drug-induced deafness in patients with acquired deafness has risen from 5 in the 50s of the last century to 40 in the 90s. In addition, tetracyclines, aspirin-like drugs, sex hormones, reaction arrest, valproic acid, etc., can cause fetal limb disability, which is mainly related to the nature of the drug itself, the dose, the duration of the drug and the gestational age at the time of medication.

4. Disability caused by accidents: The number of accidents, such as enterprises, mines, traffic accidents, etc., has increased year by year, according to the statistics of about 400,000 in 1994. In addition, sports injuries, birth injuries, etc., can also cause craniocerebral injuries, musculoskeletal system injuries, etc.

Physical disability in children caused by trauma accounts for the proportion.
