Causes, complications, and consequences of neurodevelopmental disorders: encountered in a cohort of adults with childhood-onset brain dysfunction who are institutionalized.


Introduction:

In their 1997 article, Carl Tyler and Claire Bourguet discussed the national trend to deinstitutionalize de·in·sti·tu·tion·al·ize

In their research, the authors gathered information on 21 adults at the time of deinstitutionalization de·in·sti·tu·tion·al·i·za·tion

At deinstitutionalization, each patient had an average of 2.0 diagnoses related to chronic conditions with an average of 2.1 long-term medications. After one year of community care, they had an average of 2.9 diagnoses with an average of 1.7 long-term medications. Fifty percent of these diagnoses (which included hepatitis B Hepatitis B Definition

After one year of community-based practice, none of the patients had to be re-admitted to institutions. Although there were no quantitative comparisons made, many patients showed functional improvement in activities of daily living (most notably a patient who was wheelchair bound while institutionalized gained the ability to ambulate am·bu·late

Based on their findings, the authors discuss six main recommendations that should be heeded in order to better care for this patient population, whether institutionalized or not. First, it is important for physicians to attempt to identify the cause of a patient's mental retardation mental retardation, below average level of intellectual functioning, usually defined by an IQ of below 70 to 75, combined with limitations in the skills necessary for daily living.  so that one can be vigilant for syndrome-specific health complications that may occur. Second, look for conditions commonly seen in persons with mental retardation, such as hepatitis B, dysphagia, aspiration aspiration /as·pi·ra·tion/ (as?pi-ra´shun)

Fourth, identify and treat secondary disabilities or consequences that may occur as a result of a patient's primary complications. Fifth, apply medication reduction strategies. Lastly, preventative health care strategies are essential and should be implemented in this population.

In the years following Tyler and Bourget's work, other studies have been published discussing the issues faced by patients with neurodevelopmental disorders Neurodevelopmental disorders such as fragile X syndrome are severe disabling conditions often associated with life-long impairment. History

Their data showed that of those patients that followed up, more than half had new health concerns diagnosed (63 percent had one concern, 25 percent had two, and 12 percent more than two). Henderson, et al., performed a study of patients with Down syndrome Down syndrome, congenital disorder characterized by mild to severe mental retardation, slow physical development, and characteristic physical features. Down syndrome affects about 1 in every 730 live births and occurs in all populations equally.  and reported that certain medical conditions See carpal tunnel syndrome, computer vision syndrome, dry eyes and deep vein thrombosis.  occur more frequently in this group of adults.

It was with this work in mind that the following research project was begun.

Therefore, the purpose of this study is to show that NDD patients do not simply have an isolated condition, but rather a broad spectrum of complications and consequences that are related to the initial cause of dysfunction (i.e. the neurodevelopmental disorder).

Results:

The population being studied in this report consisted of 43 males whose ages varied from 27-75 years with a mean of 49. Table 1 shows the prevalence of the main "complications" of NDD in this population. Overall, 100 percent of patients had a cognitive dysfunction, 91percent had a motor dysfunction, 84 percent had seizures, and 51 percent had behavioral issues. Unit 1 patients had an average of 3.2 complications where Unit 2 patients had an average of 3.3. Motor dysfunction and seizures were more prevalent in Unit 2, whereas, behavioral issues were more common in Unit 1. Table 2 shows the prevalence of certain common "consequences". Overall, pneumonia pneumonia (nmōn`yə), acute infection of one or both lungs that can be caused by a bacterium, usually Streptococcus pneumoniae , GERD, scoliosis, polypharmacy, dental problems, and visual deficits were seen in over 50 percent of the population. When examining each consequence individually, certain trends were observed. Pneumonia was evident in 93 percent of the patients in Unit 1 but was only seen in 57 percent of Unit 2 patients. Similarly, chronic lung disease lung disease Pulmonary disease Pulmonology Any condition causing or indicating impaired lung function Types of LD Obstructive lung disease–↓ in air flow caused by a narrowing or blockage of airways–eg, asthma, emphysema, chronic bronchitis;  (47 percent vs. 18 percent), oropharyngeal oropharyngeal /oro·pha·ryn·ge·al/ (-fah-rin´je-al)

 (40 percent vs. 21percent) had prevalence rates that were much higher in Unit 1. Scoliosis (47 percent vs. 68 percent) and dental problems (20 percent vs. 68 percent) were the only two consequences seen at much higher rates in Unit 2. Table 3 shows the prevalence of various causes of NDDs. As a group, genetic disorders The following is a list of genetic disorders and their origins. Beside most disorders is a code that indicates the type of fertilization and the chromosome involved.

Acquired disorders An acquired disorder is a medical condition which develops post-fetally; in contrast with a congenital disorder, which is present at birth. A congenital disorder may be antecedent to an acquired disorder (such as Eisenmenger's syndrome).  caused 35 percent of cases, with prematurity being the single most common cause (9 percent) of that group. Unknown causes comprised 42 percent of cases, and was therefore the most common category. Thus, a precise etiologic diagnosis (i.e. a specific neurodevelopmental disorder) has not been established for most of our patients with a childhood-onset brain dysfunction.

Discussion:

After reviewing the charts of these 43 patients, it is clear how NDDs present as a constellation Constellation, ship

 of complications and consequences. Hunterdon Developmental Center provided for a sample size with a variety of NDD causes. The specific etiologic origins of NDDs were not evenly divided with 42 percent having unknown causes, 23 percent having genetic causes, and 35 percent having acquired causes. Also, patients in this study were found to average 3.3 complications of NDDs. With regards to secondary consequences, pneumonia, GERD, scoliosis, polypharmacy, dental concerns, and visual deficits were the most common ones in this population.

The differences in the complications and consequences observed in Unit 1 versus Unit 2 can be explained by the manner in which Hunterdon divides their patients. For the most part, patients at this facility are assigned to a unit based on their functional abilities. Unit 1 is located in the Health Services health services Managed care The benefits covered under a health contract  Residence building and consists of patients with severe complications and medical consequences. This can be noted by the fact that this unit has a high incidence of pneumonia, chronic lung disease, oropharyngeal dysphagia, and feeding tube placement. In contrast, Unit 2 consists of patients who are non-ambulatory and more prone to seizures. Therefore, these patients had a higher number of motor and seizure complications but fewer consequences that required immediate medical attention.

The primary limitation of this study was its small sample size (n=43). Also, the charts reviewed were those of patients who were more medically ill (Unit 1) or more likely to be non-ambulatory (Unit 2) than a typical NDD patient, which introduced selection bias into this study. In addition, this was a retrospective study retrospective study,

 so it was subject to the bias of the original charting physician and staff. For future studies, it would be advised to perform a cohort study A cohort study is a form of longitudinal study used in medicine and social science. It is one type of study design.
