Development disorders.
Mental retardation.
Personality disorders.
Pervasive Development Disorders
• is a group of conditions that involve
delays in the development of many
basic skills, most notably the ability
to socialize with others, to
communicate and to use
imagination. Children with these
conditions often are confused in their
thinking and generally have
problems understanding the world
around them.
Types of pervasive development
disorders:
• Autism
• Asperger’s syndrome
• Childhood disintegrative disorder
• Rett’s syndrome
• Pervasive development disorder not
otherwise specified
• Autism: Children with autism have
problems with social interaction,
pretend play and communication.
They also have a limited range of
activities and interests. Many (nearly
75%) of children with autism also
have some degree of mental
retardation.
The symptoms of autism
• 1. impairment in social interaction,
• 2. impairment in communication
• 3. impairment in behavior.
• Impairment in social interaction
- fail to develop normal personal
interactions in virtually every setting.
- affected behaviors can include eye
contact, facial expressions, and body
postures.
- inability to develop normal peer and
sibling relationships, the child seems
isolated.
- little or no joy or interest in normal age-
appropriate activities. Affected children or
adults do not seek out peers for play or
other social interactions
Communication
• What the individual understands
(receptive language) as well as what
is actually spoken by the individual
(expressive language) is significantly
delayed or nonexistent.
• Deficits in language comprehension
(inability to understand simple
directions, questions, or commands)
• Absence of dramatic or pretend play
• Repetitive, abnormal behaviors.
• hypersensitivity to sensory input
through vision, hearing, or touch.
• hyposensitivity to the same type of
stimulation.
• The causes of autism
• tuberous sclerosis (an inherited disorder),
the fragile X syndrome, cerebral
dysgenesis etc.
• Genetic factors – heritability is 90%. Many
of the non-autistic co-twins had learning
or social disabilities.
• Prenatal factors (maternal infection,
gestational diabetes, influence of
teratogens, maternal stress, ultrasound
etc.), perinatal and postnatal factors
(poisoning with mercury, side-effects of
vaccines, autoimmune disease, use of
paracetamole, vitamin D deficiency, viral
infection etc.).
• Treatment of autism
• educational or vocational program that is
suited to the developmental level of the
child or adult, respectively.
A fundamental behavior such as putting
hands on the tabletop, for example, must
be mastered before the child is required to
perform any other tasks, or before more
information is presented.
• No medication has consistently proven to
be of benefit in closely controlled clinical
trials.
• Asperger's syndrome: children have
difficulty with social interaction and
communication, and have a narrow range
of interests. However, children with
Asperger's have average or above
average intelligence, and develop normally
in the areas of language and cognition.
They have difficulty concentrating and may
have poor coordination.
• Asperger syndrome
• limited interests or an unusual preoccupation
with a particular subject to the exclusion of other
activities
• repetitive routines or rituals
• peculiarities in speech and language, such as
speaking in an overly formal manner or in a
monotone, or taking figures of speech literally
• socially and emotionally inappropriate behavior
and the inability to interact successfully with
peers
• problems with non-verbal communication,
including the restricted use of gestures, limited or
inappropriate facial expressions, or a stiff gaze
• clumsy and uncoordinated motor movements
A treatment program includes:
• social skills training, a form of group therapy that
teaches children the skills they need to interact
more successfully with other children
• cognitive behavioral therapy, a type of 'talk'
therapy that can help the more explosive or
anxious children to manage their emotions better
and cut back on obsessive interests and repetitive
routines
• medication for co-existing conditions such as
depression and anxiety
• occupational or physical therapy for children with
sensory integration problems or poor motor
coordination
• specialized speech/language therapy to help
children who have trouble with normal conversation
• parent training and support, to teach parents
behavioral techniques to use at home
• Childhood disintegrative disorder:
Children with this rare condition begin their
development normally in all areas,
physical and mental. At some point,
usually between 2 and 10 years of age, a
child with this illness loses many of the
skills he or she has developed.
• Childhood disintegrative disorder
• Language skills
• Receptive language skills
• Social skills & self-care skills
• Control over bowel and bladder
• Play skills
• Motor skills
• The exact causes of childhood disintegrative
disorder are still unknown. Sometimes it occurs
within days or weeks, while in other cases it
develops over a longer period of time.
• CDD has also been associated with certain other
conditions, particularly the following:
• Lipid storage diseases is a toxic buildup of
excess fats (lipids) in the brain and nervous
system.
• Subacute sclerosing panencephalitis: Chronic
infection of the brain by a form of the measles
virus causes subacute sclerosing panencephalitis.
This condition leads to brain inflammation and
the death of nerve cells.
• Tuberous sclerosis is a genetic disorder when
tumors may grow in the brain and other vital
organs like kidneys, heart, eyes, lungs, and skin.
In this condition, noncancerous (benign) tumors,
hamartomas, grow in the brain
• Rett's syndrome: children generally suffer
the loss of many motor or movement,
skills—such as walking and use of their
hands—and develop poor coordination.
• linked to a defect on the X chromosome,
so it almost always affects girls.
Mental retardation
• is a condition diagnosed before age
18 that includes below-average
general intellectual function, and a
lack of the skills necessary for daily
living.
• Mental retardation affects about 1 -
3% of the population.
Causes of mental retardation:
• Infections (present at birth or
occurring after birth)
– Congenital CMV
– Congenital rubella
– Congenital toxoplasmosis
– Encephalitis
– HIV infection
– Listeriosis
– Meningitis
• Chromosomal abnormalities
– Chromosome deletions (cri du chat
syndrome)
– Chromosomal translocations
– Defects in the chromosome or
chromosomal inheritance (for example,
fragile X syndrome, Angelman
syndrome, Prader-Willi syndrome)
– Errors of chromosome numbers (such
as Down syndrome)
• Environmental
– Deprivation syndrome
• Genetic abnormalities and inherited
metabolic disorders
– Adrenoleukodystrophy
– Galactosemia
– Hunter syndrome
– Hurler syndrome
– Lesch-Nyhan syndrome
– Phenylketonuria
– Rett syndrome
– Tay-Sachs disease
– Tuberous sclerosis
• Metabolic
– Congenital hypothyroid
– Hypoglycemia (poorly regulated diabetes)
– Reye syndrome
– Hyperbilirubinemia
Nutritional
– Malnutrition
• Toxic
– Intrauterine exposure to alcohol, cocaine,
amphetamines, and other drugs
– Lead poisoning
– Methylmercury poisoning
• Trauma (before and after birth)
– Intracranial hemorrhage before or after birth
– Lack of oxygen to the brain before, during, or after birth
– Severe head injury
Symptoms of mental retardation
• Continued infant-like behavior
• Decreased learning ability
• Failure to meet the markers of
intellectual development
• Inability to meet educational
demands at school
• Lack of curiosity
• Behavioral disturbances
– aggression, self-injury, inattention,
hyperactivity, anxiety, depression, sleep
disturbances, and stereotypic behaviors.
– have difficult temperaments,
noncompliance, hyperactivity, poor
social skills, and delays in play skills.
• Language delay
– delayed expressive language
development
– Many infants are thought to be deaf at
presentation owing to lack of expressive
language and environmental inattention.
• Fine motor/adaptive delay
– Significant delays in self-feeding, toileting,
and play skills
– Prolonged and messy finger feeding often is
accompanied by oral-motor incoordination.
– lack of interest in age-appropriate toys and
delays in imaginative play and reciprocal play
with age-matched peers. Odd, repetitive
behaviors often replace imaginative play with
symbolic toys.
• Gross motor delay
– Delays in gross motor development
Neurologic and physical abnormalities
– seizure disorders, microcephaly,
macrocephaly, history of intrauterine or
postnatal growth retardation,
prematurity, and congenital anomalies.
• Comorbid psychiatric conditions
- Schizophrenia may have a prevalence of 3% in
individuals with MR, compared to 0.8% in the
general population.
– Bipolar disorder has a 2- to 3-fold greater
prevalence in the cognitively impaired than in
the general population.
– Attention deficit/hyperactivity disorder (ADHD)
is diagnosed in 8-15% of children and 17-52%
of adults with MR.
– Self-injurious behaviors require treatment in 3-
15%, particularly in the severe range of MR.
– Major depression, autistic spectrum disorders,
obsessive-compulsive disorder, anxiety
disorders, conduct disorder, tic disorders, and
other stereotypic behaviors are diagnosed
more commonly in the cognitively impaired.
• Mortality/Morbidity
• Neurologic dysfunction resulting in
immobility, significant oral motor
incoordination, dysphagia, and aspiration
confers a greater risk of premature death.
When significant neurologic dysfunction is
associated with other organ system
anomalies, an individual's life expectancy
is shortened further.
• Respiratory disease is the most prevalent
cause of death among individuals with
profound mental retardation.
