Learning disabilities result from general problems in the brain rather than specific genetic or neurological defects, the British Association Festival of Science in Salford was told on Tuesday. There are four main types of genetic inheritance, single, multifactorial, chromosome abnormalities, and mitochondrial inheritance. A significant proportion of children with learning disability will have an underlying genetic cause. Affected individuals usually have delayed development of speech and language by age 2. Poor brain development causes learning disabilities in 2% to 3% of the population, but the problem is more prevalent in males. What's your experience of using our hospitals and services? Mostly, learning disabilities occur because there is an enormous range of variation that occurs normally in people’s cognitive strengths and weaknesses. The two most common genetic causes of intellectual disabilities are Down syndrome and Fragile X syndrome. Many intellectual disabilities (ID, formerly mental retardation) are caused by genetic abnormalities. There are thousands of different causes of learning disabilities. In this article, we'll focus on a handful of causes of learning disabilities and briefly define them to give parents, teachers, and family members a greater understanding of how broad the realm of a learning disability really is. However, for many children the causes of their learning disability Learning disabilities (LD) vary from person to person. Researchers working on this project are Examples of such accidents are development of an extra chromosome 18 (trisomy 18) and Down syndrome, which is the most common genetic cause. For everyday healthy living advice and services information. Much like a line of dominoes, one learning disability can affect another aspect of learning or academic development. Specific causes of learning disabilities can have associated phenotypes including specific physical and mental ill-health e.g. Let’s take a look at how genetic factors of specific learning disabilities can be passed on to children.

The latter can include effects such as pollution or lifestyle effects such as smoking, drug use and diet. Autism and Asperger's syndrome. Fragile X syndrome. • Prader-Willi syndrome and affective psychosis inherited genetic learning disability; genetic mutations, or chromosomal abnormalities taking place at or around the point of conception; illness, either in the mother during pregnancy, or in the child during early years. Possible causes include the following: An inherited condition, meaning that certain genes passed from the parents affected the brain development, for example Fragile X. A parent may have a learning disability and their child may not. Global developmental delay. Some known causes include chromosomal abnormalities, such as Down syndrome, and single-gene disorders, such as fragile X syndrome. Method. Exact causes of learning Disabilities are not known but some factors are linked with Learning Disorder. The first theory is the cognitive theory. Based on this theory, if children have parents with learning disabilities, then they will essentially inherit the disability as well, they will essentially “learn” the disability.

No one really knows what causes a learning disability. Sometimes the specific cause is not known. Numerous factors cause learning disabilities, and each of them affects different areas or centers of the brain.

There may possibly be a genetic link that causes people in families to have learning disabilities. This theory also states that processes for thinking, memory, problem solving, and knowing are all affected by the brain’s processor. These processing problems can interfere with learning basic skills such as reading, writing and/or math. Tell us your experience of our services, have your say, and more.

Heredity: It is observed that a child, whose parents have had a learning disability, is likely to develop the same disorder. In the USA, Down Syndrome is the most common genetic condition, and about 6,000 babies with Down Syndrome are born each year. Vygotsky’s theory of social development states that learning develops from the interaction with people and the interaction within the mind of the person.

Reading disabilities run in families and this familiarity may be due in part to genetic influences and in part to environment. Along those same lines, a genetic diagnosis may provide the ability to anticipate associated comorbidities and other affected organ systems that have not yet been recognized.
