major causes and examples of MR
infection, intoxication, trauma or physical agent, disturbances in metabolism, conditions related to new growths, uncertain or presumed psychological causes
inflammation of the brsin/ causes brain damage.
Encephalitis (infection)
Inflammation of meninges around the brain causing damage
Meningitis (infection)
increase in temperature may lead to convulsions/ brain involvement. Contagious, scarlet rash, streptcocci
Scarlett Fever (infection)
MR in child due to mother contracting disease during pregnancy. Also results in deafness, cardiac malformation, catarcts, etc
Rubella (infection)
contracted from Mother to fetus, symptoms are progressive.
Congential Syphilis (infection)
congenital infection from intake (by Mother) of an organism usually transmitted through poorly cooked meats, particularly chicken.
Toxoplasmosis (infection)
may have disease involving the brain and therefore , develop delays, intellectual abnormalities, etc.
Aids (infection)
Other related to infection
aids, cytomegalic inclusion disease, herpes (infection)
causes from infection
encephalitis, meningitis, scarlet fever, rubella, congenital syphilis, toxoplasmosis, aids, cytomegalic inculsion disease, herpes
causes from intoxication
toxemia, fetal alcohol syndrome, smoking/nicotine intoxication, hyperbilirubin, post-immunization reactions, lead poisoning, carbon monoxide, botulism-food poisoning, and nutrasweet/saccharin
damage to the brain (pip) or post natally due to ingestion of too much of a foreign agent
intoxication
retention of salt leading to increased BP and retention of fluids resulting in harm to the baby
toxemia (intoxication)
due to ingestion of too much alcohol during pregnancy. have low birth weight with unique facial features such as "Hachet Faced"
Fetal Alchol Syndrome (intoxication)
poisioning that leads to low birth weight, premature, "at risk" for "failure to thrive"
smoking/nicotine intoxication
presence of bile in blood stream, very mild cases seen as "jaundice". If allowed to progress will become quite serious. Many times related to blood incompatiblility between Mother and baby
Hyperbilirubin (intoxication)
allergic reaction to live virus, such as MMR, etc.
Post-immunization reactions (intoxication)
other common causes from intoxication include:
lead poisoning, carbon monoxide, botulism-food poisoning and nutrasweet/saccharin (intoxication)
damage to brain from x-rays, amniocentesis, ultrasound, etc
prenatal testing (trauma or physical agent)
forceps, difficult labor/poor birth positioning (Breech-presentation of baby's bottom 1st instead of head 1st)
Mechanical Injuries at Birth (trauma or physical agent)
cord around neck at birth, animia of Mother, compression of the cord
asphyxia (trauma or physical agent)
drop on head during birth process, pressure or blow to soft spot, falls (from bed)
postnatal testing (trauma or physical agent)
m.r. related to disturbances in metabolism
usually congenital and may be ethnic specific
high level of lipids deposited in tissues, nerves, brain, and blood due to inability to metabolize because of absence of enzyme
lipid storage disorders (metabolism)
incidence in Jewish people of European decent. Due to lack of specific enzyme, fat is stored in nerve and brain cells. Death by 18 months old
Tay-Sachs disease (metabolism)
poor breakdown of carbohydrates due to defective enzymes, get interference of brain metabolism due to inadequate supply of glucose of high level of it
carbohydrate metabolism disorders (metabolism)
state requirement to test at birth prior to discharge from hospital. can't convert phenylpyruvic acid to tyroside
phenylketonuria (metabolism)
accumulation of galactose "milksugar" in blood stream, deposits in tissues
galatosemia (metabolism)
abnormally low blood glucose level
hypogycemia (metabolism)
related to trauma or physical agent
prenatal testing, mechanical injuries at birth, asphyxia, postnatal head injury, thrombosis
related to disturbances in metabolism
lipid storage disorders, tay-sachs disease, carbohydrate metabolism disorders, phenylketonuria, galatosemia, hypoglycemia
M.R. related to conditions of New Growth
have some growth occuring in the cerebrum
conditions related to new growth
neurofibromatosis, tuberous sclerosis,
von recklinghausen's disease. heredity tumors within the skull lead to increased intracranial pressure and facial compression. Associated with epilepsy. May be progressive. "cafe o'lait" spots and external neuro-fibromas present
neurofibromatosis (new growth)
hereditary multiple nodules deposited through the brain and CNS with convulsive seizures, progressive mental disorder
tuberous sclerosis (new growth)
M.R. related to new growths
neurofibromatosis and tuberous sclerosis
M.R. related to uncertain or presumed psychological causes
cultural-familiar retardation, psychogenic retardation, psychotic or major personality disorders
usually 1 or more parents are retarded, some degree of cultural deprivation, usually mild M.R.
cultural-familiar retardation (uncertain or presumed psychological causes)
usually associated with emotional disturbances, deprived or normal learning situations, experience will be different either due to impaired sensory functioning or a typical cultural experience
psychogenic retardation (uncertain or presumed psychological causes)
associated with autism, schizophrenia, etc
psychotic or mojor personality disordersm (certain or presumed psychological causes)
