Childhood disintegrative disorder (CDD), also known as Heller's syndrome and disintegrative psychosis, was originally described by Austrian educator Theodor Heller in 1908, 35 years before Leo Kanner and Hans Asperger described autism, but it has not been officially recognised until recently. Heller had previously used the name dementia infantilis for the syndrome.[1] CDD is a rare condition(1.7 cases per 100,000 condition).[2][3] Characterized by late onset (>3 years of age) of developmental delays in language, social function, and motor skills. Researchers have not been successful in finding a cause for the disorder. CDD has some similarity to autism, and is sometimes considered a low-functioning form of it.[4][5]
CDD has an apparent period of fairly normal development is often noted before a regression in skills or a series of regressions in skills.[6] The age at which this regression can occur varies,[7] and typically after 3 years typical development.[8] The regression can be so dramatic, that the child may be aware of it, and in its beginning he may even ask, vocally, what is happening to him. Some children describe or appear to be reacting to hallucinations, but the most obvious symptom is that skills apparently attained are lost.
Many children are already somewhat delayed when the disorder becomes apparent, but these delays are not always obvious in young children. This has been described by many writers as a devastating condition, affecting both the family and the individual's future. As is the case with all pervasive developmental disorder categories, there is considerable controversy about the right treatment for CDD.
Signs and symptoms
A child affected with childhood disintegrative disorder shows normal development and he/she acquires "normal development of age-appropriate verbal and nonverbal communication, social relationships, motor, play and self-care skills" comparable to other children of the same age. However, from between the age of 2 through the age of 10, skills acquired are lost almost completely in at least two of the following six functional areas:
- Expressive language skills (being able to produce speech and communicate a message)
- Receptive language skills (comprehension of language - listening and understanding what is communicated)
- Social skills & self care skills
- Control over bowel and bladder
- Play skills
- Motor skills
Lack of normal function or impairment also occurs in at least two of the following three areas:
- Social interaction
- Communication
- Repetitive behavior & interest patterns
In her book, Thinking in Pictures, Temple Grandin claims that comparing to "Kanner's classic autism" and to Asperger syndrome, CDD is characterized with more severe sensory processing disorder but less severe cognitive problems. She also claims that comparing to most persons with autism, persons with CDD have more severe speech pathology and they usually do not respond well to stimulants.
Causes
All of the causes of childhood disintegrative disorder are still unknown. Sometimes CDD surfaces abruptly within days or weeks, while in other cases it develops over a longer period of time. A Mayo Clinic report indicates: "Comprehensive medical and neurological examinations in children diagnosed with childhood disintegrative disorder seldom uncover an underlying medical or neurological cause. Although the occurrence of epilepsy is higher in children with childhood disintegrative disorder, experts don't know whether epilepsy plays a role in causing the disorder."[9] Child abuse may appear as this disorder,as in the case of young Daniel Pelka, whom died of abuse,(despite many persons noting signs of abuse but not linking together and investigating with depth), and due to the covering up of his true affliction by one of the parents, had been considered by Dr Supratik Chakraborthy as possibly having poor health and actions due to autism,and in need of testing for autism.< www.news.com.au,,article by Matthew Cooper,AAP,1 AUG 2013,"Opportunities missed to save Daniel Pelka>
CDD has also been associated with certain other conditions, particularly the following:
- Lipid storage diseases: In this condition, a toxic buildup of excess fats (lipids) takes place 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 (TSC): TSC is a genetic disorder. In this disorder, 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.
Treatment
 |
Loss of language and skills related to social interaction and self-care are serious. The affected children face ongoing disabilities in certain areas and require long term care. Treatment of CDD involves both behavior therapy, environmental therapy and medications.
- Behavior therapy: Applied Behavior Analysis (ABA) main aim is to systematically teach the child to relearn language, self-care and social skills. The treatment programs designed in this respect "use a system of rewards to reinforce desirable behaviors and discourage problem behavior." ABA programs may be designed by a board-certified specialist in behavior analysis called a "BCBA" (Board Certified Behavior Analyst), but ABA is also widely used by a number of other health care personnel from different fields like psychologists, speech therapists, physical therapists and occupational therapists with differing levels of expertise. Parents, teachers and caregivers are instructed to use these behavior therapy methods at all times.
- Environmental Therapy: Sensory Enrichment Therapy uses enrichment of the sensory experience to improve symptoms in autism, many of which are common to CDD.
- Medications: There are no medications available to directly treat CDD. Antipsychotic medications are used to treat severe behavior problems like aggressive stance and repetitive behavior patterns. Anticonvulsant medications are used to control seizures.
