[Treatment of rapid nodding "salaam" spasms in childhood]
Insights
Blitz nodding spasms, a severe neurological disorder, affect boys more often and are linked to genetic factors and perinatal brain damage. Early treatment with hormonal therapy and other drugs showed limited success, with most children experiencing developmental delays or early death.
Area of Science:
- Neurology
- Pediatrics
- Epidemiology
Background:
- "Blitz" nodding spasms present a significant challenge in pediatric neurology.
- The etiology and epidemiology of this condition require further investigation.
- Early onset and severe developmental impact are characteristic features.
Purpose of the Study:
- To investigate the etiology and epidemiology of "blitz" nodding spasms.
- To evaluate the effectiveness of various therapeutic interventions.
- To assess the long-term outcomes and prognosis in affected children.
Main Methods:
- Longitudinal study of 70 children diagnosed with "blitz" nodding spasms between 1965 and 1976.
- Clinical observation, electroencephalographic (EEG) examination, and assessment of psychomotor development.
- Administration of various therapies including ACTH, nitrazepam, and other anticonvulsants.
Main Results:
- A higher prevalence in boys, with evidence suggesting a role for genetic factors and perinatal brain damage.
- Early signs of psychomotor retardation were observed in most children due to early brain damage.
- EEG findings frequently showed type I (generalized) hypsarrhythmia.
- Therapeutic regimens required frequent revisions and combination treatments.
- Only 5 out of 70 children showed age-appropriate development; 18 died before age 5 from infections.
Conclusions:
- Perinatal brain damage is a critical factor in the etiology of "blitz" nodding spasms.
- Current therapeutic strategies, including hormonal therapy and newer drugs, have limited efficacy in improving prognosis.
- The condition is associated with severe developmental impairment and high mortality rates.
Abstract:
The paper deals with the etiology and epidemiology of "blitz" nodding spasms. The course of the disease was followed in 70 children who received various kinds of therapy within 1965 to 1976. Apparent prevalence of boys, role of genetic factors and the decisive importance of perinatal damages are noted. Even in the initial stage of the disease most children showed apparent signs of psychomotor retardation because of an early damage to the brain. The earliest time of the disease onset was the third week of life. An electroencephalographic examination showed a prevalence of type I (generalized) hypsarrhythmia. Treatment with ACTH and nitrazepam (radedorm) and in some cases also with apidan, lepsiral and chlopazepam was given. Frequent revision of the treatment schemes and combined treatment were found necessary. Only 5 of the 70 children developed in accordance with age; 18 children died of intercurrent infections at an age of under 5 years. Modern drugs (nitrazepam, dipromyl acetate, chlonazepam) did not improve the disease prognosis and could not replace completely the hormonal therapy.
