Summary
Moyamoya syndrome, a rare cerebrovascular condition, was observed in two children with Down syndrome. This association highlights the importance of monitoring neurological symptoms in pediatric Down syndrome patients.
Area of Science:
- Neurology
- Pediatrics
- Genetics
Background:
- Down syndrome is a genetic disorder associated with various health complications.
- Moyamoya syndrome is a rare, progressive cerebrovascular disease.
- The co-occurrence of Down syndrome and Moyamoya syndrome is exceptionally uncommon.
Observation:
- Two pediatric patients with Down syndrome presented with neurological deficits.
- Age of patients: 3-year-old and 6-year-old females.
- Clinical presentation included persistent neurological deficits.
Findings:
- Cerebral angiography confirmed the characteristic Moyamoya pattern in both cases.
- Magnetic-resonance angiography and digital-subtraction angiography were utilized for diagnosis.
- One patient developed epilepsy secondary to the cerebrovascular condition.
Implications:
- This case series suggests a potential link between Down syndrome and Moyamoya syndrome.
- Early recognition and monitoring of neurological symptoms in children with Down syndrome are crucial.
- Further research is warranted to understand the underlying mechanisms of this association.

02:57Meiosis vs. Mitosis
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.

01:49Meiosis I
Meiosis is a carefully orchestrated set of cell divisions, the goal of which—in humans—is to produce haploid sperm or eggs, each containing half the number of chromosomes present in somatic cells elsewhere in the body. Meiosis I is the first such division, and involves several key steps, among them: condensation of replicated chromosomes in diploid cells; the pairing of homologous chromosomes and their exchange of information; and finally, the separation of homologous chromosomes by a...
03:09Meiosis I
Meiosis is the division of a diploid cell into haploid cells forming sperm and eggs in animals through differentiation. Meiosis I is the first stage of meiosis, where the genetic recombination of homologous chromosomes and the reduction of the ploidy level by half occurs.
Prophase I is the most extended and complex step of meiosis I characterized by synapsis, chromosome pairing, and recombination of the homologous chromosomes. This process is facilitated by a proteinaceous structure called the...

01:29Nondisjunction
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.

01:21Nondisjunction
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold sister...
