Local parent support groups are an excellent start. What evaluations and services can the DSCRC provide to families, in addition to the care provided by their pediatrician? Kennedy Krieger has so much to offer—referrals for appropriate evaluations and services from multiple disciplines can be provided.
When a child is seen in our clinic for the first time, in addition to a complete medical and developmental evaluation, a physical therapy evaluation is usually scheduled, as motor delay is a prevailing concern for parents during the first year.
Raising a child with special needs is a long journey, and navigating through the system is almost always a challenge.
To schedule an evaluation for your child with Dr. Bay, please call Kennedy Krieger Institute at During that time, Dr. Capone cycled miles to surpass his target of miles. Thank you to all who supported this effort. Support the Down Syndrome Clinic and Research Center: Support Our Down Syndrome Clinic and Research Center Your financial gift ensures that children, adolescents, and adults with Down syndrome are able to participate in studies designed to advance treatment now and in the future.
Current Down Syndrome Research Initiatives at Kennedy Krieger Institute: Sleep Apnea and Beta-Amyloid in Adults with Down syndrome, Ages Years Researchers at Kennedy Krieger Institute and Johns Hopkins University are recruiting for a study examining the relationship between sleep apnea and beta-amyloid protein, which plays a role in dementia and can impair thinking and cognition.
Participants will receive an assessment for sleep apnea and undergo a lumbar puncture in order to measure the amount of beta-amyloid in spinal fluid. Compensation is offered for your time. Please contact the study coordinator, Cathleen Weadon, at for more information.
Clinical Trial for Adults with Down syndrome, Ages Years The purpose of this study is to learn about the safety, tolerability, and efficacy of a new drug RG This drug may improve learning, memory, and behavior in people with Down syndrome, but this cannot yet be confirmed. This study involves taking the investigational drug twice a day by mouth for about six months. Sometimes in coincidence with a decrease in frequency of the epileptic seizures, the cognitive ability improves slghtly.
In the first years of the disease, the motor and visuomotor functions are better preserved than language skills that are constantly compromised. The aetiology of the cognitive and behavioural disturbances is not clear.
Risk factor for the presence of mental retardation are the onset of the epilepsy in the 1st year of life, high recurrence of seizures, status epilepticus and the presence of additional minor seizures.
Other neurological symptoms, such as progressive ataxia and pyramidal signs, give these patients a characteristic aspect. With the recurrence of febrile and afebrile seizures, abnormalities become evident consisting of generalized, focal or multifocal anomalies, such as multifocal spikes, spike and waves, polyspike and waves discharges and a slowing of background activity. The intermittent light stimulation can be positive even before 1 year.
Photosensitivity is not a constant feature during the course of the disease but in SMEI patients there is a photosensitivity spectrum because this response can persist and in some patients can be used as self-stimulation [ 15 ].
In general paroxysmal activity tends to disappear while awake but is prominent during sleep. Ictal EEG anomalies, are suggestive of the syndrome and have been reported by Dravet e coll. The EEG discharge is bilateral but according to three modalities: 1 bilateral abnormalities from onset as slow spike or slow waves followed by a brief attenuation, 2 initially bilateral abnormalities becoming asymmetric, 3 bilateral and symmetric at their onset.
The postictal EEG shows diffuse flattening or slowing. Moreover, the peculiar clinical seizures and EEG features still not permit the real nature of this syndrome if multifocal or generalized. Brain imaging Neuroimaging studies CT and MRI , do not show any typical brain lesions even if brain abnormalities may exist [ 17 ] In a recent review by Striano and coll.
These findings, if confirmed do not support the association in between prolonged febrile seizures and hippocampal sclerosis as previously reported by Siegler [ 19 ] in a retrospective study in 10 of 14 patients. Diagnosis DS is still a clinical diagnosis that is mainly based on seizure history, clinical aspects, neurologic examination, EEG pattern and a long observation.
In Appendix 1 are reported some diagnostic criteria. Currently, the diagnosis is suspected and performed earlier than before, because of the possibilities offered by molecular diagnosis.
These seizures start early and persist beyond 6 years of age. The afebrile seizures usually begin in childhood a continuum with febrile seizures being characteristic, occurring often after a variable seizure-free period.
The prognosis is relatively benign without severe neurologic impairment. The first gene is SCN1B located on 19q Baulac et al [ 20 ] localized another gene of the gamma aminobutyric acid receptor GABA A on chromosome 5q34 but only few patients show this abnormality [ 21 ] Differential diagnosis The differential diagnosis must consider simple febrile seizures, benign myoclonic epilepsy, LGS, MAE and the progressive myoclonic epilepsy.
Thus, it is advised to closely follow-up the cases to prevent such hurdles and to have a multidisciplinary specialized follow-up, with pediatricians, nurses, psychologists, physiotherapists, a home care team, and an educational system to patients and their parents.
