✓ Peer-reviewed alzhub usefulness score 33 out of 100. Down syndrome and Alzheimer's

Topic: Brain proteins, microglia and lab models

Down Syndrome (DS) is the most common of the chromosomal disorders and manifests abnormalities in several organ systems. While mental retardation, skull and brain anomalies, and the development of Alzheimer-type neuropathological changes in patients greater than age 40 years are well recognized by neurologists and neuropathologists, less appreciated are the various cervical spine abnormalities that can occur. Widening of the anterior atlanto-odontoid distance (AAOD) and atlantooccipital instability occur in up to 21% and 63% of DS patients, respectively, but neurologic complaints are uncommon and rarely are severe enough to contribute to the patient's demise. We present a case of 49-year-old DS patient whose triplegia, subacute progressive respiratory failure, and death could be attributed to severe degenerative joint disease of the cervical spine with osteophyte formation and severe spinal canal stenosis. We provide the first detailed correlation study between pre-mortem magnetic resonance imaging (MRI) and extensive autoptic dissection in an adult DS patient with cervical spine abnormalities, as well as a review of the literature.

Key findings

Why it matters

This case report describes a 49-year-old person with Down syndrome whose triplegia, respiratory failure and death were attributed to severe degenerative cervical spine disease. It concerns cervical spine abnormalities, not the treatment, cure or prevention of Alzheimer's disease.

Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, so that was left out: it earned 32 of the 96 points we could judge it on, which is 33 out of 100.
