What are three things that can cause an acquired neurodevelopmental disorder?
What Causes Neurodevelopmental Disorders?
- Low birth weight.
- Environmental contaminants, such as lead.
- Fetal exposure to smoking, alcohol, recreational drugs, or medications during pregnancy.
- Premature birth.
What are examples of neurodevelopmental disorders?
Examples of neurodevelopmental disorders in children include attention-deficit/hyperactivity disorder (ADHD), autism, learning disabilities, intellectual disability (also known as mental retardation), conduct disorders, cerebral palsy, and impairments in vision and hearing.

- Lead.
- Methylmercury.
- PCBs.
- Organophosphate pesticides.
- Organochlorine pesticides.
- Endocrine disruptors.
- Automotive exhaust.
- Polycyclic aromatic hydrocarbons.
What is complex neurodevelopmental disorder?
Complex neurodevelopmental disorders, such as schizophrenia, autism, attention deficit (hyperactivity) disorder, (manic) depressive illness and addiction, are thought to result from an interaction between genetic and environmental factors.
What are the neurodevelopmental disorders DSM 5?
The DSM-5 categorizes the following disorders under Neurodevelopmental Disorders:
- Intellectual Disorders:
- Communication Disorders.
- Autism Spectrum Disorder.
- Attention-Deficit/Hyperactivity Disorder.
- Specific Learning Disorders.
- Motor Disorders.
- Tic Disorders.
- Other Neurodevelopmental Disorders.
What is neurobehavioral disorder?
Neurobehavioral disorders are composed of a large group of behavioral impairments seen in association with brain disease (e.g., stroke, multiple sclerosis, dementia, and neuro-oncological conditions), transient as well as permanent brain impairments (e.g., metabolic and toxic encephalopathies), and/or injury (e.g..
What toxins can cause developmental disabilities?
Lead, mercury, and polychlorinated biphenyls (PCBs) have been extensively studied and found to impair development at levels of exposure currently experienced by significant portions of the general population. High-dose exposures to each of these chemicals cause catastrophic developmental effects.
What are some environmental factors that can cause a learning disability?
Environmental causes of learning and behavior problems, as contrasted with genetic or congenital causes, are explored for the purpose of alerting the learning disabilities professional to those conditions for which remedial measures may be taken These environmental causes fall into five general categories chronic …
What are the two most common neurodevelopmental disorders?
Introduction: Autism spectrum disorder (ASD) and attention deficit and hyperactivity disorder (ADHD) are the two most common neurodevelopmental disorders observed in childhood.
Is Asperger’s a neurodevelopmental disorder?
Asperger syndrome is a neurodevelopmental disorder within the large family of autism spectrum disorder. It is characterized by impaired social communication and interaction, average or superior intelligence, and no significant language delay.
How are toxic chemicals linked to brain disorders?
Toxic chemicals linked to brain disorders in children A recent study indicates that children’s exposure to certain chemicals, including some pesticides, may trigger disabilities such as autism, attention-deficit hyperactivity disorder, and dyslexia.
What are the effects of toxic chemicals on children?
Toxic chemicals may be triggering recent increases in neurodevelopmental disabilities among children — such as autism, attention-deficit hyperactivity disorder, and dyslexia — according to a new study from Harvard School of Public Health (HSPH) and Icahn School of Medicine at Mount Sinai.
How are environmental factors related to neurodevelopmental disorders?
Interactions of environmental contaminants and other environmental factors may combine to increase the risk of neurodevelopmental disorders. For example, exposure to lead may have stronger effects on neurodevelopment among children with lower socioeconomic status.
How are PCBs linked to neurodevelopmental disorders in children?
Several studies of children who were prenatally exposed to elevated levels of polychlorinated biphenyls (PCBs) have suggested linkages between these contaminants and neurodevelopmental effects, including lowered intelligence and behavioral deficits such as inattention and impulsive behavior.
