Causes and Prevention of Intellectual Disability Intellectual disability can be caused by any condition that impairs development of the brain before birth, during birth or in the childhood years. Several hundred causes have been discovered, but in about one-third of the people affected, the cause remains unknown.

Mental Illness Basics Experts believe that many mental conditions are linked to problems in multiple genes -- not just one, as with many diseases -- which is why a person inherits a susceptibility to a mental disorder but doesn't always develop the condition.

Autism vs. mental retardation Mental Retardation generally refers to one's intelligence quotient (IQ). It is not about the symptoms listed about. Those who fall below and IQ of 70 (2 std dev below the mean) qualify for a diagnosis of mental retardation.

- Intellectual disability originates before the age of 18 and may result from physical causes, such as autism or cerebral palsy, or from nonphysical causes, such as lack of stimulation and adult responsiveness.

What Is Risperidone Used For? Schizophrenia is one of the most confusing and disabling mental illnesses. It is a group of mental disorders that involve abnormal thinking.

- Because there are lots of kinds of learning disabilities, it is hard to diagnose them and pinpoint the causes. LDs seem to be caused by the brain, but the exact causes are not known. Some risk factors are: 1  Heredity. 2  Low birth weight, prematurity, birth trauma or distress. 3  Stress before or after birth.

- Males with a MECP2 mutation suffer severe encephalopathy (brain disease) and die before their first birthday. More detail: Rett syndrome is a uniform and striking, progressive neurologic developmental disorder and one of the most common causes of mental retardation in females.irls with the syndrome show normal development during the first 6-18 months of life followed first by a period of stagnation and then by rapid regression in motor and language skills. The hallmark of Rett syndrome is the loss of purposeful hand use and its replacement with stereotyped hand-wringing.

- I do believe this idea of environmental causes of mental illness deserves a close look. Every human body/being is different so just one thing probably would not be the cause of distress in all cases, e.g. 'childhood trauma' OR environmental factors, e.g. bacteria, fungi, etc.

Mental Illness Basics What Causes Mental Illness? Although the exact cause of most mental illnesses is not known, it is becoming clear through research that many of these conditions are caused by a combination of genetic, biological, psychological, and environmental factors -- not personal weakness or a character defect -- and recovery from a mental illness is not simply a matter of will and self-discipline.

fragile X syndrome It is the most common form of inherited mental retardation. Fragile X syndrome is caused by a mutation in the FMR-1 gene, located on the X chromosome. The role of the gene is unclear, but it is probably important in early development.

Overview It's not known what causes schizophrenia, but researchers believe that a combination of genetics and environment contributes to development of the disorder. Problems with certain naturally occurring brain chemicals, including neurotransmitters called dopamine and glutamate, also may contribute to schizophrenia.

Cancer Mental health disorders in children and adolescents are caused mostly by biology and environment. Examples of biological causes are genetics, chemical imbalances in the body, or damage to the central nervous system, such as a head injury.

The roots of mental illness Yet for other conditions, such as depression or anxiety, the biological foundation is more nebulous. Often, McNally notes, mental illnesses are likely to have multiple causes, including genetic, biological and environmental factors. Of course, that's true for many chronic diseases, heart disease and diabetes included.
