The Role of Neurophysiology in the Treatment of Rett Syndrome
Rett syndrome, named after Dr. Andreas Rett (Briggs,2014) who first identified the condition, is a severe neurodevelopment disorder characterized by compromised brain functions, severe mental retardation, language and learning disabilities, repetitive stereotyped hand movements, and developmental regression (Liyanage & Rastegar, 2014). The high prevalence of Rett syndrome in small children and the associated developmental regression have supported the fact that Rett syndrome is a neurodevelopmental disorder. However, recent studies on adult mice with Rett syndrome suggest that it is a neurological disorder rather than a neurodevelopmental disorder. A neurodevelopmental disorder

They experience stunted growth, low weight, and smaller head circumference. During the first 2 years of life females undergo a deceleration of linear growth and weight decreases as well in proportion to height. Height and weight for girls with Rett syndrome typically falls below the expected height and weight for girls of their age (Smeets, Pelc, & Dan, 2012). Chahrour and Zoghbi (2007) warn that one of the early indicators of Rett syndrome is the deceleration of head growth, which leads to microcephaly, a condition where a patient’s head is significantly smaller than normal for their age and sex. Signs of microcephaly do not normally appear until the child’s second year of life. Although microcephaly is common in patients with Rett syndrome it is no longer essential for a diagnosis. Recent data on Rett syndrome patients shows that patients can have Rett syndrome but the circumference of their head is considered normal for their age. Therefore, the decline in head growth may be very obvious in classical cases of Rett, but it may not be present at all in atypical cases of Rett. Therefore, microcephaly is no longer an essential criterion for a Rett syndrome diagnosis (Smeets et al., …show more content…
Molecular testing does have the potential to lead to an early confirmation of Rett syndrome in an infant girl. Molecular testing would identify any MECP2 gene mutation. There are more than 200 different MECP2 mutations and in patients with classic Rett syndrome there is a 90% detection rate (Smeets et al., 2012). Often patients diagnosed with Rett syndrome show symptoms of autism and it is not unlikely that a patient could have both autism and Rett syndrome. Younger patients with Rett syndrome or intellectual disabilities actually have a higher likelihood to have a false diagnosis where their Rett syndrome symptoms are confused with autism and lead to a misdiagnosis (Briggs, 2014). The primary form of diagnosis for Rett syndrome is still based off of the previously listed symptoms and then some form of molecular testing may

    • Look for any characteristic of abnormality in shape or features of face and body. • Observe child's behaviour and interaction. If the child is alert, interested in new objects, keen to explore and relates in a friendly manner, a developmental problem is more likely because of an isolated condition rather than global retardation. • Observe growth of child including their head circumference. • Check children patterns of growth in weight, height and head circumference by observing infant health clinic booklet.…

    For example, posterior encephalocele is more often associated with neurological problems, while anterior encephalocele usually does not contain brain tissue. Thus, an infant is more likely to live if it has anterior encephalocele. An infant’s symptoms usually include poor vision, developmental delays, and seizures (“Encephaloceles - NORD (National Organization for Rare Disorders),” n.d.). Surgery to treat encephalocele includes placing the protruding tissue back into the skull or removing the sac. In this way, the surgeon tries to remove all of the protrusion without causing long-term neurological damage.…

    Signs and Symptoms Symptoms of hydrocephalus differ with age, disease development, and individual variations in acceptance to the illness. For instance, a child's capability to compensate for enlarged CSF pressure and extension of the ventricles varies from a grown-up's. The infant skull can enlarge to accommodate the buildup of CSF because the sutures (the fibrous joints that attach the bones of the skull) have not yet closed. In infancy, the clearest sign of hydrocephalus is frequently a fast growth in head circumference or a strangely big head size.…

    Craniosynostosis is a birth defect that causes one or more of these sutures in the skull to close prematurely. Craniosynostosis occurs in one out of two thousand live births and affects males twice as often as females. When these sutures prematurely fuse, it prevents the brain from growing and developing in the space needed. Some symptoms of craniosynotosis are unusual head shape, slow or no growth in head size as the baby gets older, earlier disappearance of the soft spot, and increased skull pressure. There are different types of craniosynostosis and each one causes a…

    Introduction Asymmetry is one of the most unusual and interesting errors of human reproduction. Subtle, asymmetric variation of the contra lateral structures of the head and face occur commonly in the general population in the absence of any local lesion or condition. [1] Some of these changes, however, may slowly but steadily progress and exhibit asymmetrical development. These changes usually do not follow any particular relationship with time or modifying circumstances such as trauma and often have been termed hemihypertrophy, congenital hemihypertrophy, hemimacrosomia, or partial gigantism. This phenomenon was first described by Meckel in 1822 [2] and reported first by Wagner in1839.…

    Fragile X syndrome (FXS) is a genetic disorder that is the most common cause of inherited mental retardation. Although often compared to autism, FXS is a comprehensive disorder, characterized by numerous physical and behavioral symptoms. FXS is a caused by trinucleotide repeats on the X chromosome, which prevents the production of the protein FMRP, that is necessary for normal brain functioning. It is important for parents, educators, and the general population to better understand this syndrome, as interventions must be targeted for the characteristics specific to FXS, rather than simply lumping it together with autism and expecting that those methods will be beneficial to the child. Fragile X syndrome affects about one out of every five…

    Starting in 2012, the year of the London Olympics, the International Olympics Committee knew that Brazil was not prepared to host the 2016 Olympics. This is because of several things such as water contamination and a lack of facilities and man power. Another major reason that the Olympics should not have been held in Rio is the Zika virus. Zika is a virus spread through mosquitos and sexual activity. It causes a minor sickness to the male population but can cause many things to happen to a woman if she becomes pregnant.…

    If an individual is suspected of displaying physical signs and symptoms of a disease or condition, a genetic test could confirm it. While some family members may seem unaffected by a genetic abnormality, a test could identify reproductive or psychosocial implications, putting the unaffected members at a higher risk of developing the disease. Diagnostic testing is suitable for all ages and can be performed at birth or any time during life, though it could alter their health care choices and medical…

    Researchers have found many genes that are associated with autism. Other researchers have found irregularities in certain parts of the brain. There are even others that have found abnormal serotonin levels in brains of those with autism. That research suggests that there may be a disruption in fetal brain development that is possibly caused by defects in genes that control brain growth. This could be caused by environmental factors that disrupt gene regulation.…
